Other Ingredients (2)

Hypoallergenic Plant FiberFiller

Plant-derived cellulose fiber used as a hypoallergenic filler, common in Thorne and Pure Encapsulations products

Capsule ShellCapsule

Generic capsule shell where the label does not specify the material. Common materials are hypromellose (HPMC) for vegetarian capsules and gelatin for traditional capsules — both are GRAS-listed and safe. Fish gelatin and pullulan variants also exist.

How to Take It

Take it anytime

No evidence a formula this broad works better at any particular hour. Take it with a meal containing fat — the vitamins A, D, E and K in it absorb poorly without one.

With a meal containing fat
Space it a couple of hours from Iron and Calcium

On the label

As a dietary supplement, take 1 capsule with each meal.

General guidance based on the ingredients, not a substitute for the label or your doctor.
