Vegan/Vegetarian Delayed-Release HMPC Capsule

We use a special delayed-release capsule for our probiotic. The delayed-release makes sure that the probiotic is released in your gut where it will have the greatest effect, rather than breaking down in your stomach acid.

Our capsule shell is made from HMPC (hypromellose), so it contains 0% gelatine. This means they are suitable for everybody including both vegetarians and vegans.
