Multiple studies have shown that individuals who supplement with creatine experience greater increases in muscle strength, power, and endurance compared to non-users. For example, a meta-analysis published in the Journal of the International Society of Sports Nutrition found consistent performance improvements among athletes and recreational exercisers using creatine. Creatine is naturally present in foods such as red meat and fish, but supplementation is a common and well-researched strategy to maximize muscle stores. The typical supplementation protocol involves a loading phase followed by a maintenance dose. Creatine is generally safe for healthy adults, but it is important to stay hydrated and consult with a healthcare professional, particularly if you have kidney concerns or other medical conditions.

34. Taurine

Taurine is a sulfur-containing amino acid that plays a multifaceted role in the human body, especially in energy production, nerve function, and cardiovascular health. It is involved in the regulation of calcium signaling within cells, supports mitochondrial function, and helps stabilize cell membranes, all of which contribute to efficient energy metabolism and muscle performance. Taurine also assists in neurotransmitter regulation, aiding in the transmission of nerve impulses and supporting overall nervous system health.

Taurine is commonly found in energy drinks, where it is marketed as a performance and alertness enhancer. Research, such as that reviewed by the Journal of Functional Foods, indicates that taurine supplementation may have modest benefits for reducing exercise-induced fatigue and supporting muscle recovery. However, these effects are often modest and can be influenced by the combination of other stimulants, such as caffeine, often present in energy drinks. Taurine is naturally present in meat, fish, and dairy products, and most people meet their needs through a balanced diet. Supplementation is generally considered safe for healthy adults at moderate doses, but excessive intake from energy drinks or supplements should be approached cautiously and discussed with a healthcare professional.

35. Glutamine

Glutamine is the most abundant amino acid in the body and plays a vital role in energy support, particularly during periods of illness, injury, or intense physical stress. It serves as a key fuel source for rapidly dividing cells, such as those in the immune system and the lining of the digestive tract, helping to maintain muscle mass and overall metabolic balance during catabolic states. Glutamine also supports nitrogen transport and acid-base balance, both crucial for optimal cellular energy production and recovery.

Clinical studies in hospital settings have shown that glutamine supplementation can benefit critically ill patients by supporting immune function, reducing infection rates, and improving outcomes in trauma or burn recovery. For example, research in the Journal of Parenteral and Enteral Nutrition highlights its use in parenteral nutrition to reduce hospital stays and complications. Most healthy individuals synthesize enough glutamine endogenously and obtain additional amounts from dietary sources such as meat, eggs, dairy products, beans, and certain vegetables. Supplementation may be warranted during times of extreme stress, critical illness, or high-intensity training, but should be guided by a healthcare professional to ensure safe and appropriate use.

36. Vitamin B Complex

The B vitamin complex consists of eight distinct vitamins—B1 (thiamine), B2 (riboflavin), B3 (niacin), B5 (pantothenic acid), B6 (pyridoxine), B7 (biotin), B9 (folate), and B12 (cobalamin)—that work synergistically to support energy production and overall metabolic health. These vitamins serve as coenzymes in the breakdown of carbohydrates, fats, and proteins, facilitating the conversion of food into ATP, the body’s primary energy molecule. Together, they also support nerve function, red blood cell formation, and stress resilience, making them essential for sustained physical and mental energy.

While supplements can be effective for individuals with diagnosed deficiencies or absorption issues, research—such as that from the Nutrients journal—suggests that obtaining B vitamins from whole foods promotes better absorption and provides additional health benefits from other nutrients and fiber. Good dietary sources include whole grains, lean meats, eggs, dairy products, legumes, leafy greens, seeds, and nuts. For most people, a balanced, varied diet is the best way to ensure adequate intake of all B vitamins. If supplementation is required, it should be used under medical supervision to avoid excess and ensure balanced nutrient intake.

37. Sulfur

Sulfur is a key mineral found in several energy-related amino acids, including methionine and cysteine, which are crucial for protein synthesis and cellular metabolism. As part of these amino acids and other sulfur-containing compounds like glutathione, sulfur supports detoxification processes, antioxidant defense, and the production of enzymes required for generating ATP—the body’s main energy source. Proper sulfur balance helps maintain healthy cartilage and connective tissue, promote efficient energy cycles, and protect the body from oxidative stress.

Although outright sulfur deficiency is rare, inadequate intake may result in symptoms such as fatigue, poor wound healing, brittle hair or nails, and joint discomfort. Most people meet their sulfur needs through the regular consumption of protein-rich foods. Good dietary sources include meats, poultry, fish, eggs, dairy products, legumes, onions, garlic, and cruciferous vegetables like broccoli and Brussels sprouts. According to the National Institutes of Health (NIH), a balanced diet with adequate protein is typically sufficient to maintain optimal sulfur status. For those with restricted diets, focusing on both animal and plant-based protein sources can help ensure adequate sulfur intake and support ongoing energy production.

38. Vitamin B8 (Inositol)

Inositol, often referred to as vitamin B8, is a naturally occurring compound that plays a vital role in cell signaling pathways, which are essential for energy regulation, mood, and metabolic function. Inositol is a component of cell membranes and serves as a precursor for molecules involved in transmitting signals inside cells, particularly those related to insulin and neurotransmitter activity. Through these actions, inositol influences how the body processes glucose and generates cellular energy, thereby supporting overall vitality and emotional balance.

Research has demonstrated inositol’s benefits in improving insulin sensitivity and energy metabolism, particularly in individuals with metabolic syndrome or polycystic ovary syndrome (PCOS). For instance, a review in the International Journal of Molecular Sciences found that inositol supplementation can enhance glucose uptake and support metabolic health. Dietary sources of inositol include fruits (especially cantaloupe and citrus), beans, nuts, seeds, whole grains, and organ meats. Although the body can synthesize inositol from glucose, a diet rich in these foods may provide additional metabolic support. For those considering supplementation, it is best to consult a healthcare professional to determine appropriate dosage and ensure safety.

39. Vitamin B4 (Adenine)

Adenine, sometimes referred to as vitamin B4, is a purine base that plays a foundational role in both DNA structure and cellular energy transfer. Adenine is one of the four nucleotides that make up DNA and RNA, ensuring the proper storage and transmission of genetic information in every cell. Most importantly for energy, adenine is a critical component of adenosine triphosphate (ATP), the primary energy carrier in the body. ATP is responsible for delivering energy to power countless cellular processes, including muscle contraction, nerve impulse transmission, and metabolic reactions.

While adenine is not officially classified as a vitamin by major health authorities today, research continues to explore its importance in cellular metabolism and genetic function. A review in the Journal of Physiology emphasizes adenine’s role in the structure of ATP and energy cycling. The body can synthesize adenine, but it is also available from dietary sources such as whole grains, organ meats, fish, eggs, nuts, and legumes. Consuming a balanced diet rich in these foods supports both DNA synthesis and optimal cellular energy production, making adenine a cornerstone for sustained vitality and metabolic health.

40. PQQ (Pyrroloquinoline Quinone)

Pyrroloquinoline quinone (PQQ) is a redox cofactor and antioxidant found in plant foods that has gained attention for its role in supporting mitochondrial health and energy production. PQQ is believed to stimulate the growth of new mitochondria (mitochondrial biogenesis) and protect existing mitochondria from oxidative damage, enabling cells to generate ATP more efficiently. By enhancing the number and function of mitochondria, PQQ may contribute to improved cellular energy, cognitive function, and overall vitality.

Supplementation trials have investigated PQQ’s impact on energy and fatigue. For example, a study published in the Journal of Nutritional Biochemistry found that daily PQQ supplementation reduced markers of fatigue and improved sleep quality in healthy adults. PQQ is naturally present in foods such as kiwi, green peppers, parsley, tofu, and fermented soybeans (natto), but only in small amounts. While available as a dietary supplement, current evidence suggests that moderate doses are generally well-tolerated, though long-term safety has not been fully established. It is best to consult with a healthcare provider before starting PQQ supplements, especially for those with underlying health conditions or who are pregnant or breastfeeding.

41. Lipoic Acid

Lipoic acid, also known as alpha-lipoic acid (ALA), is a unique antioxidant that plays a dual role in protecting cells from oxidative stress and supporting energy metabolism. As a cofactor in mitochondrial enzyme complexes, lipoic acid is essential for the conversion of carbohydrates into ATP, the body’s main source of energy. Its antioxidant capability allows it to neutralize free radicals both in water- and fat-soluble environments, helping to regenerate other antioxidants like vitamin C and glutathione.

Numerous studies have explored lipoic acid’s benefits, particularly in individuals with diabetes. Research summarized in the Diabetes Care journal indicates that lipoic acid supplementation can improve insulin sensitivity and reduce symptoms of diabetic neuropathy, such as fatigue and nerve pain. Dietary sources of lipoic acid include spinach, broccoli, organ meats, and potatoes, but the amounts are relatively low compared to supplement forms. Lipoic acid supplements are generally well-tolerated, but individuals with diabetes or other medical conditions should consult a healthcare professional before use, as it may interact with blood sugar levels and certain medications. For more information, refer to the NIH Alpha-Lipoic Acid Fact Sheet.

42. Carnitine

Carnitine is a naturally occurring compound that plays a crucial role in cellular energy production by transporting long-chain fatty acids into the mitochondria, where they are oxidized to generate ATP. This shuttling process is essential for the efficient metabolism of fats, particularly during periods of increased energy demand such as exercise or fasting. Without adequate carnitine, fatty acids cannot effectively enter the mitochondria, leading to reduced energy output and potential accumulation of fat in tissues.

Carnitine deficiency is rare but may occur due to genetic disorders affecting carnitine transport or synthesis, as well as certain medical conditions or medications. Symptoms of deficiency can include muscle weakness, fatigue, and, in severe cases, heart and liver dysfunction. According to the National Center for Biotechnology Information (NCBI), genetic carnitine deficiencies may require lifelong supplementation. For the general population, dietary sources such as red meat, poultry, fish, and dairy products provide sufficient carnitine. Plant-based foods contain much lower levels, so vegetarians and vegans should ensure a balanced diet with adequate protein. For more information, refer to the NIH Carnitine Fact Sheet and consult a healthcare provider for personalized advice.

43. Vitamin H

Vitamin H, more commonly known as biotin or vitamin B7, is a water-soluble B vitamin essential for the body’s energy metabolism. It acts as a coenzyme in the breakdown of carbohydrates, fats, and proteins, enabling the conversion of these macronutrients into glucose and, ultimately, ATP—the primary energy molecule used by cells. By supporting these metabolic pathways, vitamin H/biotin is vital for maintaining steady energy levels, healthy skin, hair, and nervous system function.

There is complete overlap between vitamin H and vitamin B7, as they are different names for the same nutrient. Biotin is well-researched for its role in enzymatic reactions that facilitate energy production at the cellular level. Deficiency is uncommon but can occur in cases of malnutrition, genetic disorders, or prolonged consumption of raw egg whites, which contain avidin and inhibit biotin absorption. Symptoms may include fatigue, thinning hair, skin rashes, and neurological issues. To ensure adequate intake, include foods such as eggs (cooked), nuts, seeds, salmon, sweet potatoes, and leafy greens in your regular diet. For further reading, refer to the NIH Biotin Fact Sheet and consult a healthcare provider if you are concerned about your biotin status.

44. Manganese

Manganese is a trace mineral essential for activating several enzymes that are crucial for energy metabolism and antioxidant defense. It functions as a cofactor for enzymes involved in the breakdown of carbohydrates, amino acids, and cholesterol, facilitating the conversion of nutrients into ATP, the cell’s main energy source. Manganese-dependent enzymes, such as superoxide dismutase, also help protect cells from oxidative stress, further supporting efficient energy production and cellular health.

Intake of manganese can vary widely based on dietary habits and regional differences in food and soil content. According to the National Institutes of Health (NIH), most people in developed countries get sufficient manganese through a balanced diet, but those who consume little whole grains, nuts, or leafy vegetables may be at risk for suboptimal intake. Symptoms of deficiency, while rare, can include poor bone health, impaired glucose tolerance, and reduced energy levels. To ensure adequate manganese intake, include foods such as whole grains (brown rice, oats), nuts, legumes, leafy greens, and tea. For more information on safe intake and dietary sources, consult the NIH factsheet or a registered dietitian.

45. Vitamin B10 (Para-aminobenzoic acid)

Vitamin B10, also known as para-aminobenzoic acid (PABA), is a compound once considered part of the B vitamin complex due to its role in folic acid synthesis in bacteria. However, its significance in human nutrition is controversial, as the human body does not require PABA directly and it is not recognized as an essential vitamin by major health authorities. While PABA acts as a precursor in the synthesis of folate by intestinal bacteria, humans obtain sufficient folate from dietary sources, making direct PABA supplementation largely unnecessary.

Research on PABA’s benefits and requirements in humans remains limited. Some historical and anecdotal uses include its application for skin health and as a sunscreen ingredient, as discussed by the National Center for Biotechnology Information (NCBI). However, there is little scientific evidence supporting a vital role for PABA in energy metabolism or overall nutrition. For most people, focusing on a well-balanced diet rich in natural sources of B vitamins—such as leafy greens, legumes, whole grains, and animal products—provides all the necessary nutrients for optimal energy. Supplementation with PABA is generally not recommended unless prescribed for specific medical reasons, and it is best to consult a healthcare professional before use.

46. Betaine

Betaine, also known as trimethylglycine, is a naturally occurring compound that plays a critical role in methylation—an essential process for many biochemical reactions, including those involved in energy production. Methylation is necessary for the synthesis of creatine, DNA repair, and the regulation of homocysteine levels, which collectively support efficient cellular metabolism and overall vitality. By donating methyl groups, betaine helps facilitate these energy-related reactions and maintains healthy liver and cardiovascular function.

Studies on betaine supplementation in athletes have shown potential benefits for strength, power, and endurance. Research highlighted in the Journal of the International Society of Sports Nutrition suggests that betaine may support improved exercise performance and reduced fatigue, though results can vary depending on the individual and training regimen. Good dietary sources of betaine include beets, spinach, whole grains (such as quinoa and wheat bran), shellfish, and certain cereals. Including these foods in your diet can help support natural methylation processes and energy metabolism. For those considering supplementation, it is advisable to consult with a healthcare professional, especially if you have underlying health conditions or are taking medications that may interact with methylation pathways.

47. Choline

Choline is an essential nutrient that plays a crucial role in brain and muscle energy regulation. It is a precursor for acetylcholine, a neurotransmitter involved in muscle control, memory, and cognitive function. Choline also supports the structural integrity of cell membranes and is necessary for the transport and metabolism of fats, all of which contribute to efficient energy utilization and overall cellular health. A lack of choline can impair mental focus, muscle performance, and the body’s ability to generate and use energy effectively.

Choline deficiency, though relatively rare, can occur in specific populations such as pregnant women, individuals with certain genetic variations, or those following very restrictive diets. Symptoms of deficiency may include muscle damage, liver dysfunction, fatigue, and cognitive decline. According to the National Institutes of Health (NIH), adult men should aim for 550 mg per day and adult women for 425 mg per day, with higher needs during pregnancy and lactation. To support optimal choline intake, prioritize foods such as eggs (especially yolks), beef liver, chicken, fish, broccoli, and soybeans. For more about choline’s health benefits and guidance on supplementation, visit the Harvard T.H. Chan School of Public Health.

48. Vitamin F (Essential fatty acids)

Vitamin F is a collective term for essential fatty acids, primarily omega-3 and omega-6, which are vital for energy production, cell membrane structure, and inflammation regulation. These fatty acids cannot be synthesized by the body and must be obtained through diet. Omega-3s (such as EPA and DHA) are particularly important for brain function, reducing inflammation, and supporting mitochondrial efficiency, thereby promoting sustained energy and mental clarity. Omega-6 fatty acids (like linoleic acid) are essential for cell signaling and skin health, though excessive intake relative to omega-3s can promote inflammation.

A balanced ratio of omega-3 to omega-6 fatty acids is key for optimal energy and overall health. Modern diets, especially in Western countries, tend to be higher in omega-6 and lower in omega-3, which may contribute to fatigue and inflammatory conditions. To improve this balance, prioritize foods rich in omega-3s, such as fatty fish (salmon, sardines, mackerel), chia seeds, flaxseeds, and walnuts, while moderating processed oils high in omega-6. For further guidance, see the NIH Omega-3 Fatty Acids Fact Sheet and the Harvard Nutrition Source.

49. Vitamin B13 (Orotic acid)

Orotic acid, sometimes referred to as vitamin B13, is a compound involved in the metabolism of nucleic acids and energy production at the cellular level. While historically considered a vitamin, its classification and essentiality in human nutrition remain debated. Orotic acid is a precursor in the synthesis of pyrimidines, which are critical for DNA and RNA formation—processes that underpin cell growth, repair, and energy transfer. However, most healthy individuals synthesize sufficient orotic acid endogenously, and direct dietary requirements are not established.

Scientific evidence regarding the benefits of orotic acid supplementation for energy enhancement is limited and inconclusive. Some early studies suggested potential benefits for athletic recovery and liver function, but more recent research, such as that summarized by the National Center for Biotechnology Information (NCBI), indicates no clear necessity for supplementation in a balanced diet. Dietary sources of orotic acid include dairy products, organ meats, and certain vegetables, but it is not considered an essential nutrient. For most people, focusing on a varied and nutrient-rich diet is sufficient to support nucleic acid metabolism and energy production without the need for orotic acid supplements.

50. Vitamin T (Carnitine)

Vitamin T is an alternative name sometimes used for carnitine, a nutrient essential for optimal energy metabolism. Carnitine’s primary function is to facilitate the transport of long-chain fatty acids into the mitochondria, where they are oxidized to produce ATP—the fundamental energy molecule for bodily processes. This makes carnitine especially important during periods of increased energy demand, such as exercise or fasting, as it enables efficient fat utilization and supports muscle performance and endurance.

Although the term “vitamin T” is not widely recognized in modern nutrition science, carnitine itself is well studied for its metabolic roles. Most people obtain sufficient carnitine through dietary sources such as red meat, poultry, fish, and dairy products, while smaller amounts are present in some plant foods. The body can also synthesize carnitine from the amino acids lysine and methionine. Supplementation may be considered for individuals with genetic deficiencies, certain medical conditions, or restrictive diets, but it is generally unnecessary for those with a balanced diet. For further information on carnitine’s health benefits and dietary guidance, visit the NIH Carnitine Fact Sheet and consult a healthcare provider before starting supplementation.
