Vitamin B5 (Pantothenic Acid)

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.

Vitamin E

2 shared conditions Β· 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.

Saffron

Saffron is a spice with antioxidant properties derived from the flowering plant Crocus sativus. When used as a supplement, saffron seems to be effective at reducing symptoms of depression and possibly anxiety.

Rose hip, the fruit of Rosa canina, is a dietary supplement for joint health. It can alleviate symptoms of arthritis if taken daily.

Resveratrol

2 shared conditions Β· 318 outcomes

Resveratrol is a bioactive molecule found in plant sources such as grapes, peanuts, blueberries, and, famously, red wine. Resveratrol has anti-inflammatory and antioxidant properties that benefit cardiovascular function, glycemic control, and lipid metabolism. Although it’s promoted for lifespan extension, there’s no evidence for this in humans and limited evidence in animals.

Nicotinamide

Nicotinamide, also commonly known as niacinamide, is a form of vitamin B3. It is effective for the treatment of a vitamin B3 deficiency and may improve skin health.

Fish Oil

Fish oil is a mix of mostly EPA and DHA derived from fatty fish. It reduces triglycerides, but does not seem to affect the rate of cardiovascular events. It appears to reduce the symptoms of depression and improve some painful, inflammatory conditions.

Copper

2 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.
