All remedies A–Z

Short, sourced profiles of the remedies we cover. Informational only, not medical advice.

Supplement

Vitamine B7

Biotin only helps hair and nails when you are deficient, which is rare. Otherwise there is no proven benefit.

Supplement

Collageenpeptiden

Collagen peptides are marketed for skin. A few small, often industry-funded trials show minor effects.

Supplement

Visolie (EPA/DHA)

Omega-3 supports the skin barrier and may help inflammatory skin conditions a little.

Supplement

Ascorbinezuur

Vitamin C is needed to make collagen; a normal diet already covers this for most people.

Supplement

Zinc matters for skin and can help acne when you are low; it is not a cure-all.
