Honest comparison

Why not just drink AG1?

AG1 is one daily formula, the same for every user. ProtocolEngine builds a protocol around you: your goals, your routines and the supplements you already take.

Choose AG1 if

You want one scoop instead of several bottles, from a brand that says it has run clinical trials on its own formula and has it tested by third parties. For convenience, AG1 wins.

Choose ProtocolEngine if

You want a protocol built around your goals and what you already take, with the evidence grade behind each choice. Your protocol covers habits and diet too.

The honest difference

AG1 answers the question "what is an easy daily supplement?" ProtocolEngine answers "what fits my goals, and how strong is the evidence?" These are different questions, and some people will want only the first.

If you like AG1, keep it. Your protocol covers the habits and diet that no powder can.
