Manganese

Manganese is an essential trace mineral required for numerous enzymatic reactions in the body. It serves as a cofactor for manganese superoxide dismutase (MnSOD, the primary mitochondrial antioxidant), arginase (urea cycle), glutamine synthetase (ammonia detoxification), and pyruvate carboxylase (gluconeogenesis). Manganese is critical for bone formation, glucose metabolism, wound healing, and neurotransmitter synthesis. The Adequate Intake (AI) is 2.3mg/day for men and 1.8mg/day for women. Deficiency is rare due to widespread dietary availability but can cause impaired growth, skeletal abnormalities, and altered glucose tolerance. Toxicity from excessive intake (primarily occupational inhalation) can cause manganism, a Parkinson-like neurological syndrome.

Copper

3 shared conditions Β· 16 outcomes

Copper is an essential trace mineral required for numerous enzymatic reactions in the body. It serves as a cofactor for superoxide dismutase (antioxidant defense), cytochrome c oxidase (energy production), lysyl oxidase (collagen/elastin cross-linking), ceruloplasmin (iron metabolism), and dopamine Ξ²-hydroxylase (neurotransmitter synthesis). Meta-analysis evidence shows copper supplementation can improve antioxidant status and reduce oxidative stress markers. Clinical trials demonstrate benefits for wound healing, bone density in deficient populations, and immune function. The RDA is 0.9mg/day for adults. Deficiency is rare but can occur with high zinc intake, malabsorption syndromes, or gastric bypass surgery. Excess copper (>10mg/day) is associated with gastrointestinal distress and potential liver toxicity.

Poly-Ξ³-glutamic acid (Ξ³-PGA) is a polymer produced by Bacillus bacteria, found naturally in natto (fermented soybeans). Used in skincare (hydration), food industry (texture), and has research interest for health applications. NO GRADED OUTCOMES - research is mostly preclinical. May have calcium absorption, immune, and antioxidant properties. Biodegradable and safe. Primarily used topically in cosmetics rather than as an oral supplement.

Myricetin

2 shared conditions Β· 8 outcomes

Myricetin is a flavonoid found in berries, vegetables, and wine, structurally related to quercetin and kaempferol. Among flavonoids, myricetin has been particularly associated with bone health and anti-osteoporotic effects in preclinical research. Also has antioxidant and potential anti-diabetic properties. NO GRADED OUTCOMES - human research is limited. Found in foods like berries, onions, and red wine. Not widely available as an isolated supplement. Low bioavailability may limit therapeutic use.

Magnesium

Magnesium is an essential dietary mineral that is involved in energy production, nervous system function, blood pressure regulation, and blood glucose control. A lack of magnesium in the diet β€” which is common in modern societies β€” is associated with an increased risk of diabetes, cardiovascular disease, and other health conditions.

Longan

2 shared conditions Β· 7 outcomes

Dimocarpus longan (Longan or Dragon Eye) is a tropical fruit related to lychee, consumed widely in Asia. Preclinical research suggests neuroprotective and cognitive-enhancing effects from the seed and fruit extracts. NO GRADED OUTCOMES - limited human research on medicinal use. The fruit flesh is nutritious but not unique; bioactive compounds are concentrated in seeds and peel. Traditional use includes tonifying blood and calming the spirit in TCM. Safe as a food; medicinal use of extracts lacks human validation.
