Copper

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 β-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.

Myricetin

3 shared conditions ¡ 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.

Manganese

3 shared conditions ¡ 14 outcomes

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.

Cyanidin

3 shared conditions ¡ 10 outcomes

Cyanidin is a type of anthocyanin pigment found in dark berries, purple vegetables, and black rice. Cyanidin-3-glucoside (C3G) is the most studied form. Shows promise for blood glucose regulation, anti-inflammatory effects, and metabolic health. Notable for potentially improving glucose uptake without impairing muscle protein synthesis (unlike some AMPK activators). However, bioavailability is a major concern - most cyanidin is rapidly metabolized. Human evidence is limited despite promising in vitro data.

Clove

3 shared conditions ¡ 9 outcomes

Clove is a spice derived from the flower buds of Syzygium aromaticum, native to Indonesia. The primary active compound is eugenol (70-90% of clove oil), which has potent antimicrobial, analgesic, and anti-inflammatory properties. Clove oil is FDA-approved as a dental analgesic and has been used traditionally for toothache, respiratory ailments, and as an aphrodisiac. Modern research supports antimicrobial and antioxidant effects, but human clinical trials for most applications are limited.

7,8-Dihydroxyflavone

3 shared conditions ¡ 15 outcomes

7,8-DHF is a natural flavonoid which can reach the brain and activate a receptor (TrkB) that promotes neuronal growth. Some animal evidence suggests that 7,8-DHF may have some cognitive and motor benefits and may be nootropic, but no human evidence for these claims exists to date.

Vitamin K2 (MK-7)

2 shared conditions ¡ 10 outcomes

Vitamin K2 MK-7 (Menaquinone-7) is the most bioavailable form of vitamin K2, derived from natto (fermented soybeans). Unlike vitamin K1, MK-7 has a long half-life allowing it to reach extrahepatic tissues including bone and vasculature. Clinical trials demonstrate benefits for osteocalcin carboxylation, bone mineral density preservation in postmenopausal women, and arterial stiffness reduction. MK-7 activates proteins (osteocalcin, matrix Gla protein) that direct calcium to bones and away from arteries.

Vitamin K

2 shared conditions ¡ 78 outcomes

Vitamin K is a fat-soluble vitamin that plays a key role in blood coagulation, bone metabolism, and vascular health. Vitamin K1 is found in many leafy greens and soy, while vitamin K2 is found in meat and fermented foods and is synthesized by intestinal bacteria. Supplementation with vitamin K improves markers of bone health, and vitamin K is administered to newborns to prevent vitamin K deficiency bleeding.

Vitamin B5 (Pantothenic Acid)

2 shared conditions ¡ 15 outcomes

Vitamin B5 (pantothenic acid) is an essential water-soluble B-vitamin required for the synthesis of coenzyme A (CoA) and acyl carrier protein (ACP). CoA is critical for fatty acid metabolism (synthesis and beta-oxidation), acetylcholine synthesis, steroid hormone production, and the citric acid cycle. Pantothenic acid is widely distributed in foods ('pantos' means 'everywhere' in Greek), making deficiency extremely rare. The Adequate Intake (AI) is 5mg/day for adults. Clinical applications include high-dose supplementation for acne vulgaris (reduces sebum production), topical dexpanthenol (provitamin B5) for wound healing and skin barrier repair, and potential benefits for lipid profiles. Pantothenic acid has very low toxicity with no established Upper Limit.
