Lycopene

Lycopene is a red carotenoid found in tomatoes, watermelon, and pink grapefruit. Epidemiological data links higher intake to reduced prostate cancer risk, but RCT evidence is limited. May improve endothelial function in CVD patients. Accumulates in prostate and skin tissue. Cooking tomatoes INCREASES bioavailability. CAUTION: Antioxidant effects may interfere with chemotherapy/radiation - avoid during cancer treatment. Dietary sources may be superior to supplements.

Vitamin E

2 shared conditions · 274 outcomes

Vitamin E is a fat-soluble antioxidant that protects cells from oxidative damage and is found in several common foods. Supplementing with extra vitamin E does not have broad health benefits, except in people with vitamin E deficiency, and long-term high-dose supplementation may cause harm.

Copper

2 shared conditions · 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 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.

Morus Alba (White Mulberry) is a plant where both the fruit and roots have been used traditionally for vitality and immune support; it may have cognitive enhancing properties (mostly unexplored) and anti-cancer effects.

White Kidney Bean Extract

1 shared condition · 6 outcomes

White Kidney Bean extract (Phase 2) is an alpha-amylase inhibitor that blocks starch digestion. It DOES work but potency is variable and modest - blocks ~25-65% of starch calories in acute studies. Meta-analyses show ~2kg weight loss over 4-12 weeks. Must be taken with starchy meals. Undigested starch goes to colon bacteria (gas, bloating). Better for preventing weight gain than losing existing weight. Works best with high-starch meals.

Vitamin K2 (MK-7)

1 shared condition · 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.
