Supplement Ingredients Explained: Evidence, Safety and How to Choose

Every ingredient page keeps two things separate: what the scientific literature says about the ingredient, and what a manufacturer claims about a product containing it. Those are different statements and they deserve different weight.

Botanicals

Vitamins

Minerals

Nutrients

Structural and joint ingredients

Live cultures

How we treat evidence

Ingredient evidence is dose-specific and preparation-specific. A trial on a standardised extract at a defined dose does not transfer to a different extract of the same plant, and much of the research circulating online is laboratory or animal work that cannot support a claim about people. Each page says which is which, and links to the underlying reference sources.

We never claim an ingredient treats a disease. Where a regulator has issued a safety signal — as for concentrated turmeric, high-dose green tea extract and ashwagandha — we say so.
