SP-TOK · Category system

Every label carries a token. The colour is the category.

A rounded square sits top-right on every pack — Its colour tells you the product's category in line with the protocol.

SP-FORM · Bioavailable forms

The right form, at a dose your body can actually use.

Methylated B-vitamins. Chelated minerals. Triglyceride-form EPA and DHA. Bioavailability isn't a marketing word for us — it's the reason the numbers on the label match the numbers in your blood.
