Best Vitamins for People Looking to Increase Energy

Vitamin B12

Vitamin B12, also known as cobalamin, is essential for converting food into cellular energy (ATP) and maintaining healthy red blood cells, brain, and nervous system function. Deficiency in B12 is clinically linked to fatigue and weakness, as it impairs red blood cell production and oxygen delivery to cells, leading to tiredness. Supplementation with B12 is strongly supported by scientific evidence, including clinical trials and authoritative guidelines, for boosting energy especially in individuals with low B12 levels due to dietary intake or absorption issues. While B12 does not increase energy in people with normal levels, it is crucial for those deficient to improve energy and reduce fatigue. B12 is naturally found in animal-based foods and fortified products, and absorption requires intrinsic factor produced in the stomach. Safety considerations include proper diagnosis of deficiency before supplementation. Overall, B12 is a top recommended vitamin for people looking to increase energy levels based on robust research.

Vitamin B6

Vitamin B6, also known as pyridoxine, is a water-soluble vitamin essential for cellular metabolism and energy production. It acts as a critical co-factor in over 140 biochemical reactions, primarily related to amino acid metabolism, including transamination, decarboxylation, and racemization. Vitamin B6 supports the Krebs cycle and gluconeogenesis, processes vital for converting nutrients into usable cellular energy. It facilitates glycogen breakdown (glycogenolysis) to release glucose for energy, aids glucose metabolism through glycolysis, and sustains amino acid metabolism by converting amino acids into intermediates for energy production pathways like the citric acid cycle and electron transport chain. Additionally, Vitamin B6 is essential for synthesizing neurotransmitters, regulating hormonal activity, and producing hemoglobin, which improves oxygen transport necessary for energy generation in tissues. Deficiency in Vitamin B6 is linked to fatigue and decreased energy, and supplementation has been shown to benefit individuals with suboptimal B6 levels. It is found naturally in many foods such as fish, poultry, potatoes, and fruits, and is also available as dietary supplements. Proper intake of Vitamin B6 supports optimal energy levels and overall metabolic health, while excessive intake should be avoided due to potential nerve damage risks.

Vitamin B6 taken in doses of 500 mg or more daily may cause brain and nerve problems, so dosage should be carefully managed to avoid toxicity (Mayo Clinic, WebMD, Cleveland Clinic, NCBI, Drugs.com).

Product Selection Advice

When choosing a Vitamin B6 supplement to support energy production, look for products that specify the form of B6 (pyridoxine HCl vs. pyridoxal-5′-phosphate, or P5P), list the exact amount of the active ingredient per serving, and carry third-party quality certifications.

• Ingredient form & dosage: Pyridoxal-5′-phosphate (P5P) is the coenzyme form of B6 that may be more bioavailable, particularly for those with impaired conversion (e.g., older adults or people with liver issues), whereas pyridoxine HCl is a stable, cost-effective form suitable for general supplementation. Choose P5P if you need quicker, more efficient uptake; otherwise, pyridoxine HCl at 25–100 mg/day is adequate for most adults (NIH Fact Sheet).

• Label transparency: Avoid products using “proprietary blends” that don’t disclose individual ingredient amounts. A clear label should read “Pyridoxal-5′-phosphate (P5P) 50 mg” or “Pyridoxine HCl 100 mg” so you know exactly what and how much you’re getting (ConsumerLab red flags).

• Certifications & testing: Opt for supplements certified by USP, NSF, or ConsumerLab, and look for Non-GMO Project, vegan/vegetarian, and gluten-free seals if you have dietary restrictions or allergies. Third-party testing ensures potency, purity, and absence of contaminants (DSLD; Allergy Research Group).

• Brand reputation: Trusted brands with rigorous quality control include NOW Foods, Life Extension, Solgar, and Allergy Research Group. These companies offer both pyridoxine HCl and P5P products and typically list full ingredient profiles and testing credentials on their labels.

• Allergen & additive considerations: Check for minimal excipients—ideally plant-based capsules and rice flour as fillers—and confirm absence of common allergens (soy, dairy, gluten, shellfish, tree nuts) if needed.

• Red flags: Avoid supplements that claim “pharmaceutical grade,” “FDA approved lab,” or “clinically tested formula” without specifying ingredient details. Steer clear of high-dose (>200 mg/day) formulations unless under medical supervision, as excessive B6 can risk peripheral neuropathy (TGA safety alert).

• Usage tip: Take B6 with a light meal earlier in the day to support cellular energy pathways and reduce potential gastrointestinal upset.

Integration Tips

To effectively integrate Vitamin B6 supplementation into daily routines for people looking to increase energy, it is best to take the supplement consistently at a time you will remember, often in the morning to align with its potential energy-boosting effects. Vitamin B6 can be taken with or without food, but if it causes stomach upset, taking it with a meal is recommended. Always take Vitamin B6 with a full glass of water. The typical recommended daily intake for adults is around 1.3 to 1.7 mg, depending on age and gender. Avoid exceeding recommended doses to prevent side effects like numbness or sensitivity to light.

This dosage guidance is based on authoritative sources including the NIH Office of Dietary Supplements and Mayo Clinic, tailored for people seeking to increase energy through folate supplementation. (ods.od.nih.gov, mayoclinic.org, mindlabpro.com)

Safety Considerations

Folate (B9) supplementation is generally safe when taken at recommended doses. The Tolerable Upper Intake Level (UL) for folic acid from fortified foods or supplements is set at 1,000 mcg per day for adults to avoid potential adverse effects. Taking folate within recommended levels (around 400 mcg daily for most adults) is effective and safe, especially for preventing deficiency and supporting energy metabolism. However, doses above 1 mg (1,000 mcg) daily may cause side effects such as stomach upset, nausea, diarrhea, irritability, confusion, skin reactions, and seizures. Long-term high doses (0.8-1.2 mg daily or more) might increase the risk of cancer or heart issues in some individuals with preexisting heart conditions.

Folate can interact with certain medications, so it is important to avoid taking folate supplements within 2 hours before or after antacids containing aluminum or magnesium, as these can reduce folate absorption. Folate may also affect the efficacy or metabolism of drugs such as methotrexate, phenytoin, phenobarbital, primidone, some cancer treatments (fluorouracil, capecitabine, raltitrexed, tegafur), antibiotics, zinc-containing medicines, sulfasalazine, and cholestyramine. Individuals on these medications should consult their doctor before supplementing with folate.

Folate supplementation does not mask vitamin B12 deficiency with current diagnostic methods, so it is safe in that regard. Unmetabolized folic acid may be present in the bloodstream but has not been shown to cause confirmed health risks.

For people looking to increase energy, folate supports DNA synthesis and red blood cell formation, critical for energy delivery. Safety considerations include adhering to recommended doses, being aware of possible drug interactions, and consulting healthcare providers if taking medications or having health conditions.

Vitamin D Vitamin D impacts muscle function and mitochondrial energy generation. Multiple studies, including those from Harvard Health and NCBI, show a clear association between vitamin D deficiency and fatigue. Supplementation with vitamin D benefits energy levels, particularly in people with low vitamin D levels. Vitamin D helps maintain bone and muscle strength, which supports physical energy and reduces weakness. It also plays a role in reducing oxidative stress and inflammation, improving mitochondrial function, and regulating neurotransmitters linked to fatigue. Recommended supplementation doses vary by age, with vitamin D3 being the preferred form for better absorption, especially in older adults.

Vitamin D plays a crucial role in muscle function and mitochondrial energy production, which are key factors in maintaining and enhancing energy levels. Scientific studies have demonstrated that vitamin D deficiency is strongly associated with muscle weakness and fatigue. Vitamin D supports mitochondrial oxidative function in skeletal muscle, helping to reduce oxidative stress and improve ATP production, which is essential for energy generation at the cellular level. Supplementation with vitamin D has been shown to improve muscle strength and reduce fatigue symptoms, particularly in individuals with low vitamin D levels. This is because vitamin D influences muscle regeneration, mitochondrial health, and the balance of neurotransmitters linked to fatigue. Therefore, vitamin D supplementation can be beneficial for people looking to increase their energy, especially if they have a deficiency. It is important to monitor vitamin D levels and consult healthcare providers for appropriate dosing to safely integrate vitamin D into daily routines for optimal energy support.

Evidence-Based Pros

• Vitamin D supports mitochondrial chemical processes, which are essential for energy production; deficiency may negatively affect mitochondrial function leading to fatigue.
• Correcting vitamin D deficiency has been shown to significantly improve fatigue symptoms, including physical, mental, and emotional aspects, in adults with low vitamin D levels.
• Vitamin D supplementation in deficient individuals has led to significant improvements in self-perceived fatigue compared to placebo.
• Case studies report complete resolution of excessive daytime fatigue in vitamin D deficient individuals after vitamin D therapy.
• Vitamin D plays a role in regulating mood, potentially reducing negative emotions, which can indirectly support energy levels and overall well-being.

Evidence-Based Cons

• Vitamin D supplementation can lead to toxicity if taken in excessively high doses, with the upper safe limit generally considered to be 4,000 IU per day for people with normal vitamin D levels. Toxicity symptoms may include nausea, vomiting, weakness, and serious complications like kidney damage.
• Some individuals may experience side effects such as drowsiness or fatigue if vitamin D is taken in excess, which can counteract the intended energy-boosting effects.
• Vitamin D supplementation should be carefully dosed and monitored, especially in people with certain medical conditions or those taking other medications, to avoid adverse interactions or contraindications.
• The benefits of vitamin D supplementation on energy levels are primarily observed in individuals with vitamin D deficiency; supplementation in people with normal vitamin D levels may not provide noticeable energy improvements.
• Vitamin D's role in fatigue and energy is complex, and other factors beyond vitamin D deficiency may contribute to fatigue, so supplementation alone may not resolve energy issues.

Dosage Guidelines

Recommended Dosage Guidelines for Vitamin D to Increase Energy in People with Low Vitamin D Levels

• General Adult Dosage:
  • For adults aged 19 to 70 years, the recommended daily allowance (RDA) is typically 600 IU (15 mcg) per day.
  • Adults over 70 years may require 800 IU (20 mcg) per day.
• For Those with Vitamin D Deficiency or Low Levels:
  • If vitamin D deficiency is confirmed (serum 25-hydroxyvitamin D levels below 20 ng/mL), higher doses may be needed initially.
  • A common approach is to take 50,000 IU of vitamin D3 once weekly for 6 to 8 weeks to replenish levels.
  • Alternatively, moderate daily doses of around 4000 IU/day can be used, especially if testing is not immediately available.
• Maintenance Dosage:
  • After repletion, maintenance doses typically range from 800 to 2000 IU per day, depending on individual needs and blood levels.
• Special Considerations:
  • Vitamin D is best obtained through a combination of sunlight exposure, diet, and supplementation.
  • People at higher risk for deficiency include those with limited sun exposure, darker skin, older age, obesity, or certain medical conditions affecting absorption.
  • Supplementation should be done under medical supervision if high doses are used, to avoid toxicity.
• Safety and Toxicity:
  • The upper intake level generally considered safe is 4000 IU per day for most adults.
  • Excessive intake can lead to hypercalcemia with symptoms like nausea, vomiting, muscle weakness, and kidney issues.
  • Regular monitoring of blood vitamin D levels is recommended when taking high doses.
• Usage Tips:
  • Take vitamin D supplements with meals containing fat to enhance absorption.
  • Consistency in daily intake helps maintain stable blood levels.

These guidelines support improving energy levels by correcting vitamin D deficiency, which is linked to fatigue and impaired muscle function. Always consult a healthcare provider before starting supplementation, especially at higher doses.

Safety Considerations

Vitamin D supplementation is generally safe when taken at recommended doses. For most adults and children over 1 year, 10 micrograms (400 IU) daily is sufficient. Exceeding the upper safe limit of 100 micrograms (4,000 IU) per day chronically can cause hypercalcemia (excess blood calcium), manifesting as nausea, weakness, frequent urination, and muscle pain, and may lead to weakened bones, kidney damage, and heart arrhythmias. Children 1–10 years should not exceed 50 micrograms (2,000 IU) daily, and infants under 12 months should not exceed 25 micrograms (1,000 IU) daily. Individuals with conditions like granulomatous diseases, hyperparathyroidism, or renal impairment should consult a healthcare provider for lower dosing. Vitamin D overdose cannot occur from sunlight but prolonged UV exposure increases risks of skin damage and cancer; sun protection measures are recommended. These considerations ensure safe vitamin D use for energy enhancement. (NHS)

Common Side Effects

Common side effects of Vitamin D supplementation, especially relevant for people looking to increase energy, include fatigue, dizziness, nausea, vomiting, stomach pain, constipation, diarrhea, weakness, confusion, and loss of appetite. Excessive intake can also cause elevated calcium levels leading to symptoms such as increased thirst and frequent urination. Mild side effects like headaches or light-headedness may occur initially as the body adjusts. Vitamin D toxicity is rare and usually results from very high doses over a long period. It is important to follow recommended dosages and consult a healthcare professional if symptoms occur.

Product Selection Advice

When choosing a Vitamin D supplement to increase energy, consider the following guidance:

• Brand Recommendations: Trusted brands include Transparent Labs (Vitamin D3 + K2), Nutricost, Thorne, Now, Sports Research, Nature Made, Nature's Bounty, Vitafusion, Nordic Naturals, and NatureWise. These brands are recognized for quality and transparency.
• Ingredient Focus: Look for Vitamin D3 (cholecalciferol), which is better absorbed than D2. Some supplements combine Vitamin D3 with Vitamin K2 (MK-7) to enhance absorption and utilization. Dosages commonly range from 1,000 IU to 5,000 IU per serving.
• Certifications: Prefer supplements with third-party testing and certifications such as Informed Choice, NSF (National Sanitation Foundation), USP (United States Pharmacopeia), and NPA GMP. These certifications ensure product quality, ingredient accuracy, and safety.
• Form and Additives: Vitamin D supplements come in softgels, gummies, liquid drops, and chewables. Vegan options are available, such as Transparent Labs' vegan softgels. Avoid products with artificial ingredients, allergens, fillers, or misleading proprietary blends.
• Red Flags: Avoid supplements that do not clearly list the amount of Vitamin D per serving, use proprietary blends without transparency, or make exaggerated health claims. Be cautious of products with unrecognizable ingredient names or those claiming "FDA Approved" testing, as the FDA does not approve supplements.
• Safety Tips: Vitamin D is fat-soluble, so taking it with a meal containing fat improves absorption. Avoid megadoses unless prescribed by a healthcare provider, as excessive intake can cause toxicity. Consult a healthcare professional before starting supplementation, especially if on medications or with health conditions.
• Additional Considerations: For vegans, look for Vitamin D3 sourced from lichen rather than lanolin (sheep wool). Check for allergen-free labels if you have sensitivities. Liquid drops offer customizable dosing and may be preferred by those who dislike pills.

This guidance helps select a high-quality, effective Vitamin D supplement tailored to energy support and overall health needs. (Fortune, U.S. News, Verywell Fit, GoodRx, ConsumerLab)

Integration Tips

To effectively integrate Vitamin D supplements into daily routines for people looking to increase energy, consider the following tips:

• Take Vitamin D supplements consistently, as energy improvements may take about a month to manifest, especially if you have low Vitamin D levels.
• Prefer Vitamin D3 (animal source) over D2 (plant source) for slightly better efficacy, but focus more on the correct dosage.
• Aim for a daily dose between 1,000 IU and 2,000 IU for energy benefits, but consult a healthcare provider as this is an off-label use and doses above 4,000 IU should be supervised.
• Take Vitamin D with meals containing some fat to enhance absorption since it is fat-soluble.
• Consider pairing Vitamin D supplements with magnesium, omega-3 fatty acids, vitamin K2, and probiotics to improve absorption and synergistic health benefits.
• Get moderate sun exposure (10-15 minutes daily around midday) when possible to naturally boost Vitamin D levels, but balance with skin cancer risk by using sunscreen if exposure is prolonged.
• Include Vitamin D-rich foods in your diet such as salmon, trout, mushrooms exposed to UV light, fortified milk, and plant-based milks.
• Avoid taking Vitamin D with certain medications like orlistat, statins, steroids, and thiazide diuretics without medical advice.
• Monitor Vitamin D levels through blood tests to adjust supplementation as needed.

These steps help ensure Vitamin D supplementation is safe, effective, and tailored to boost energy levels for those with deficiency or low Vitamin D status. (GoodRx, Aware.app, Verywell Health)

Vitamin C

Vitamin C is a vital antioxidant that plays a core role in cellular energy metabolism by being essential for the synthesis of carnitine, a compound necessary for the transport of long-chain fatty acids into mitochondria where energy is produced. Deficiency in Vitamin C can lead to fatigue, and clinical trials confirm that supplementation restores energy levels in individuals who are deficient. Vitamin C also supports overall metabolic functions and helps reduce physical and mental fatigue. When selecting Vitamin C supplements, it is important to consider product quality, ingredient purity, and certifications to avoid allergens and contaminants. Typical usage involves daily intake through diet or supplements, with attention to recommended doses to avoid side effects such as gastrointestinal discomfort. Overall, Vitamin C supplementation is a well-supported, evidence-based approach to enhancing energy, particularly in those with inadequate Vitamin C status or increased needs.

Top Recommended Supplements

• Vitamin C - A core antioxidant necessary for carnitine synthesis which drives cellular energy metabolism. Supplementation helps restore energy in deficient individuals and reduces fatigue, especially post-viral fatigue (e.g., long COVID).
• Vitamin B Complex - Includes B1, B2, B3, B5, B6, B7, B9, and B12, essential for ATP production, red blood cell formation, and brain function. Deficiency causes fatigue and low energy.
• Vitamin D - Important for bone health and immune function. Low levels are linked to fatigue; supplementation improves symptoms in deficient individuals.
• Iron - Vital for red blood cell production and oxygen delivery. Iron deficiency anemia causes fatigue; supplementation is effective if deficient.
• Coenzyme Q10 (CoQ10) - Supports mitochondrial energy production. May improve energy but consult healthcare provider due to possible interactions.
• Ginseng and Ashwagandha - Herbal supplements that may help increase energy and reduce fatigue but have potential side effects and drug interactions.

Key Benefits

• Vitamin C is essential for energy production as it supports the synthesis of L-carnitine, which helps convert fatty acids into energy, thereby reducing fatigue and tiredness.

• Vitamin C enhances iron absorption from plant-based foods, which helps reduce fatigue and increase energy, especially important for vegans and vegetarians.
• Vitamin C acts as an antioxidant, reducing oxidative stress and inflammation in the body, which can lower the energy demands of stress on the body.

Evidence-Based Pros

• Vitamin C supplementation effectively increased work motivation and attentional focus in healthy young adults, contributing to better performance on cognitive tasks requiring sustained attention (NCBI).
• Intravenous vitamin C administration significantly reduced fatigue in office workers within two hours, with effects lasting for one day, indicating rapid and sustained energy restoration (NCBI).
• Vitamin C acts as a powerful antioxidant, reducing oxidative stress which is associated with fatigue, thereby potentially alleviating fatigue symptoms (NCBI).
• Vitamin C deficiency can cause fatigue, and supplementation restores energy in deficient individuals, supporting its role in cellular energy metabolism via carnitine synthesis (NCBI).

Evidence-Based Cons

• Taking more than 2,000 mg per day can cause unpleasant side effects such as diarrhea, nausea, and stomach cramps due to the body's inability to absorb excessive amounts.
• High doses may contribute to kidney stones, especially in individuals with kidney disorders.
• Excessive supplementation during pregnancy can affect a baby's vitamin C levels after birth.
• There are concerns about high vitamin C intake in individuals with specific health conditions, such as iron overload disorder or hereditary hemochromatosis.
• Vitamin C supplement use has shown mixed results regarding eye health, with some studies suggesting an increased risk of cataracts at high doses.

Dosage Guidelines

For people looking to increase energy, the recommended daily intake of Vitamin C is typically 75 mg for women and 90 mg for men. Pregnant women require about 85 mg, and breastfeeding women need around 120 mg daily. Some studies suggest that higher intakes, around 500 mg to 1000 mg per day, may be beneficial for boosting energy levels and overall well-being. Smokers need an additional 35 mg daily due to increased oxidative stress. Vitamin C is water-soluble, so excess amounts are excreted in urine, and doses up to 2,000 mg per day are considered safe for most adults. Taking Vitamin C in split doses (e.g., 200 mg twice daily) can improve absorption. High doses above 2,000 mg may cause side effects such as diarrhea, nausea, and stomach upset. It is best to combine supplementation with Vitamin C-rich foods like citrus fruits, bell peppers, and broccoli. Individuals with specific health conditions should consult healthcare professionals before high-dose supplementation.

Safety Considerations

Vitamin C supplements are generally safe when taken at recommended doses. However, taking high doses, especially above 2,000 milligrams per day, can cause side effects such as upset stomach, vomiting, diarrhea, heartburn, stomach cramps, bloating, headache, tiredness, and insomnia. Long-term use of very high doses increases the risk of serious side effects including kidney stones, particularly in people with a history of kidney disorders. Individuals with G6PDH deficiency may experience hemolytic anemia from high doses of vitamin C. Vitamin C can interact with certain medications and conditions: it may increase aluminum absorption from antacids containing aluminum, potentially harmful for those with kidney disease; it may interfere with chemotherapy effectiveness; it can raise estrogen levels when taken with birth control pills or hormone replacement therapy; it may reduce the efficacy of protease inhibitors, statins, and niacin; it enhances iron absorption which can be harmful in iron overload disorders such as hemochromatosis; and high doses might reduce the effectiveness of blood-thinning medications like warfarin. Before medical tests, inform healthcare providers about vitamin C supplementation as it can affect test results such as blood sugar and stool tests. Pregnant women should avoid excessive supplementation as it may affect the baby’s vitamin C levels after birth. It is advised to obtain vitamin C primarily from a balanced diet rich in fruits and vegetables. Smokers require an additional 35 mg per day due to increased oxidative stress. Overall, vitamin C supplementation should be tailored to individual health status and medication use, preferably under healthcare supervision.

Common Side Effects

Typical side effects of Vitamin C supplementation include upset stomach, vomiting, loose stools, heartburn, stomach cramps or bloating, tiredness or sleepiness, insomnia, and headache. Allergic reactions such as skin rash, itching, hives, and swelling of the face, lips, tongue, or throat can occur and require immediate medical attention. High doses above 2,000 mg/day may lead to stomach upset and diarrhea. Rare but serious side effects include kidney stones and iron overload. These side effects are particularly relevant for people taking Vitamin C to increase energy or for general health purposes.
