Frequently Asked Questions

Do whey powders need preservatives?

The low moisture keeps bacteria down, so most brands skip chemical preservatives.

What additives still appear?

Lecithin, enzymes, or anti-caking silica may remain. These are processing aids, not preservatives.

How long does preservative-free whey last?

Sealed tubs keep 18–24 months; store them cool and dry to avoid clumping.
