Niacinamide, a vitamin B3 form, supports skin health by improving barrier function, reducing inflammation, and minimizing wrinkles. It aids energy metabolism, enhances DNA repair, and may lower skin cancer risk. Found in meat, fish, and supplements.

Essential trace mineral that enhances insulin action and is involved in macronutrient metabolism.

Water-soluble vitamin (pantothenic acid) essential for synthesis of coenzyme A (CoA), critical for fatty acid metabolism.

Essential trace mineral involved in bone formation, blood clotting, and metabolism.

Essential trace mineral critical for iron metabolism, connective tissue formation, and neurotransmitter synthesis.

Folate (vitamin B9) is essential for DNA synthesis, methylation, and cell division. It is critical during pregnancy for neural tube development. Supplemental forms include folic acid (synthetic), methylfolate (5-MTHF, active form), and folinic acid. MTHFR gene variants affect folate metabolism in ~40% of the population.

Pantothenic acid (vitamin B5) is an essential water-soluble vitamin and precursor to Coenzyme A (CoA), one of the most important cofactors in metabolism. CoA participates in over 100 metabolic reactions including fatty acid synthesis/oxidation, citric acid cycle, and acetylcholine production.

Fat-soluble vitamin essential for blood clotting and bone metabolism. K1 from plants and K2 from bacteria and fermented foods.

Biotin strengthens hair, skin, and nails by supporting keratin production, and aids in metabolism by helping convert food into energy. Deficiency can lead to brittle nails or hair loss.

Niacin (vitamin B3) exists as nicotinic acid, niacinamide, and nicotinamide riboside (NR). Nicotinic acid uniquely causes vasodilatory "flush" and is the most effective natural agent for raising HDL cholesterol. All forms serve as precursors to NAD+/NADH, essential cofactors for 400+ enzymatic reactions.

Vitamin K1, also known as phylloquinone, is crucial for the synthesis of proteins involved in blood clotting and the building of bones.

Water-soluble vitamin (niacin) involved in over 400 enzymatic reactions.

Vitamin K2 MK-7 (menaquinone-7) is the most bioavailable and longest-acting form of vitamin K2, derived from natto fermentation. It activates osteocalcin (directing calcium to bones) and matrix Gla protein (preventing arterial calcification). MK-7 has a 72-hour half-life vs 1-2 hours for MK-4, making it superior for daily dosing.

L-5-MTHF, the active folate form, supports DNA synthesis and repair, crucial for cell division and fetal development. It aids homocysteine metabolism, reducing heart disease risk, and enhances mood by supporting neurotransmitter production. Leafy greens and supplements provide it.

Vitamin K2 MK4 is a form of Vitamin K2 that plays a critical role in calcium metabolism, supporting bone and cardiovascular health.

Vitamin B8 refers to inositol, a cyclohexane polyol that functions as a second messenger in insulin signaling and neurotransmitter pathways. Myo-inositol and D-chiro-inositol are the primary supplemental forms. Strong clinical evidence for PCOS, anxiety, OCD, and metabolic syndrome.

Benfotiamine, a fat-soluble vitamin B1 derivative, supports nerve health, reduces diabetic complications, and protects against oxidative stress. It enhances energy metabolism and may improve cognitive function. Found in supplements and fortified foods.

Nicotinamide riboside (NR) is a form of vitamin B3 and the most efficient oral precursor to NAD+ (nicotinamide adenine dinucleotide). NAD+ declines 50% between ages 40-60, driving aging and metabolic dysfunction. NR uniquely enters cells via NRK1/2 pathway, bypassing rate-limiting enzymes. Patented as Niagen.

Alpha Tocopherol, the primary vitamin E form, acts as a potent antioxidant, protecting cells from damage and supporting immune function. It promotes heart health and skin repair. Found in nuts, seeds, and oils.

Pyridoxal-5-Phosphate, the active vitamin B6 form, supports neurotransmitter synthesis, reducing depression and boosting brain function. It aids protein metabolism, red blood cell production, and immune health. Found in meat, fish, and supplements.

Beta Tocopherol, a vitamin E form, acts as an antioxidant, protecting cells from oxidative stress and supporting heart health by preventing lipid oxidation. It complements other tocopherols for immune support. Present in nuts, seeds, and vegetable oils.

Gamma Tocopherol, a form of vitamin E, acts as a potent antioxidant, neutralizing harmful free radicals and reducing inflammation. It may also help protect against certain cancers and heart disease by combating oxidative stress.

Delta Tocopherol, a vitamin E form, acts as a powerful antioxidant, protecting cells from oxidative damage and reducing inflammation. It supports heart health by preventing LDL cholesterol oxidation and may lower cancer risk. Found in nuts and seeds, it complements other tocopherols for overall wellness.

Adenosylcobalamin, an active vitamin B12 form, supports energy production, nerve health, and red blood cell formation. It aids mitochondrial function and may improve neurological symptoms. Found in meat, fish, and supplements.

Pantethine, a vitamin B5 derivative, lowers cholesterol by reducing LDL and triglycerides while raising HDL. It supports energy metabolism and adrenal function, promoting stress resilience. Available in supplements and small amounts in foods like liver.

Vitamin B4 refers to adenine, a purine base component of DNA, RNA, ATP, NAD, and FAD. While no longer classified as a vitamin (the body synthesizes it), adenine is essential for cellular energy, genetic material, and coenzyme function. Historical classification as a B-vitamin.

Para-aminobenzoic acid (PABA) is a B-vitamin complex factor that serves as a precursor to folate synthesis in bacteria. While not a true vitamin for humans, it has been used for skin conditions, hair graying, and as a UV protectant. Also used to counteract sulfanilamide drug effects.
