How to Read a Supplement Label (and Spot Fillers)

Short answer: A good supplement label shows the exact dose of each active ingredient, in a well-absorbed form, with minimal fillers and no vague proprietary blends. Learn to read the form (e.g. magnesium glycinate vs oxide) and check the 'other ingredients' line.

What to look for

  • Named, dosed actives: not a hidden proprietary blend.
  • Good forms: e.g. magnesium glycinate, zinc glycinate, P5P (B6).
  • Short 'other ingredients' list: minimal fillers.

Fillers worth questioning

Bulking agents and flow agents aren't always bad, but a long list of additives, artificial colours, or a 'proprietary blend (X mg)' that hides individual doses is a red flag.

We list every active and its dose on Femme Flourish, no proprietary blends, no nasty fillers.

Frequently asked questions

What is a proprietary blend?

A mix where the total is shown but individual ingredient doses are hidden, making it impossible to judge if actives are dosed effectively.

What fillers should I avoid?

Be wary of artificial colours and long additive lists; some flow agents are harmless in small amounts.

How do I know if a dose is effective?

Compare the listed dose to the amounts used in research for that ingredient.
