For each ingredient in Signal and Source, at least one published human study: what was tested, at what dose, and what it measured. Links go to the original paper.

Signal · daily amounts

Everyday doses, not megadoses.

Signal is made for every day. Every amount sits within official limits for food supplements, and at or below what human studies used.

Some studies below used higher doses than Signal. We show both numbers, so you can compare. Not for children, or for anyone pregnant or breastfeeding. Do not exceed one scoop a day.
