Monograph
Overview Vitamin E is a family of eight fat-soluble antioxidant compounds: four tocopherols (alpha, beta, gamma, delta) and four tocotrienols (alpha, beta, gamma, delta). Alpha-tocopherol is the most biologically active form in humans and the primary form measured in serum. It is the only form…

Monograph
Overview Iodine is an essential trace element required exclusively for the synthesis of thyroid hormones—thyroxine (T4) and triiodothyronine (T3)—which regulate metabolic rate, thermogenesis, cardiac output, neurological development, and nearly every organ system. Iodine deficiency is the…

Monograph
Overview Copper is an essential trace mineral and catalytic cofactor for more than 30 enzymes involved in energy metabolism, iron homeostasis, antioxidant defense, connective-tissue synthesis, neurotransmitter production, and immune function. Though required in small amounts (RDA ~0.9 mg/day)…

Monograph
Overview Chromium is a trace mineral historically classified as essential for glucose metabolism due to its proposed role in potentiating insulin signaling. While early research on "glucose tolerance factor" (GTF) generated significant clinical interest in chromium supplementation for insulin…

Monograph
Overview Manganese is an essential trace mineral required as a cofactor for dozens of enzymes spanning carbohydrate metabolism, antioxidant defense, bone formation, amino acid metabolism, and immune function. Like many trace minerals, its clinical significance is primarily on two ends of the…

Monograph
Overview Iron is a trace mineral essential for oxygen transport (hemoglobin), cellular respiration (cytochromes, mitochondrial electron transport), DNA synthesis (ribonucleotide reductase), and neurotransmitter production (tyrosine hydroxylase for dopamine/norepinephrine). Iron deficiency is…

Monograph
Overview Phosphorus is the second most abundant mineral in the body after calcium, with approximately 85% residing in bone and teeth as hydroxyapatite and the remaining 15% distributed in soft tissues and blood. It is a structural component of DNA, RNA, phospholipid membranes, and ATP—making…

Monograph
Overview Molybdenum is an ultra-trace mineral required as a cofactor for four mammalian enzymes: sulfite oxidase, xanthine oxidase/dehydrogenase, aldehyde oxidase, and mitochondrial amidoxime reducing component (mARC). Deficiency is exceptionally rare in humans outside of genetic enzyme…

Monograph
Overview Potassium is the primary intracellular cation, with ~98% residing inside cells at concentrations of 140–150 mEq/L, compared to a tightly regulated serum concentration of 3.5–5.0 mEq/L. It is fundamental to resting membrane potential, cardiac rhythm, skeletal and smooth-muscle…

Monograph
Overview Vanadium is a trace element present in tiny amounts in the human body (~0.1 mg total). It is found across all human tissues and is present in several oxidation states, most commonly as vanadate (V⁵⁺) and vanadyl (V⁴⁺) ions. Whether vanadium meets the formal criteria for an "essential"…

Monograph
Overview Strontium is an alkaline earth metal that sits directly below calcium on the periodic table and shares many of its chemical properties, including the ability to incorporate into bone mineral. Strontium ranelate, a pharmaceutical form developed in Europe, was the first bone-specific…

Monograph
Overview Conjugated linoleic acid (CLA) refers to a family of geometric and positional isomers of linoleic acid (LA, 18:2n-6) in which the double bonds are conjugated (separated by a single bond) rather than methylene-interrupted. The two biologically active isomers are c9,t11-CLA (rumenic…
