Our take on the Rule 1 Source 7 Protein

Rule 1 Source 7 is a slow-digesting protein powder built on pea protein and micellar casein, with 22g of protein and no added sugar per serving. The blend is designed for sustained amino acid release rather than a fast post-workout spike, which makes it a fit for meal replacement, between-meal hunger, or nighttime use. It is Informed Choice certified and screened for banned substances, a step many budget plant-and-casein blends skip. Against a plain whey isolate it digests slower and mixes thicker; against pure casein it adds pea protein for a dairy-light amino acid profile.

Questions and answers

Is Source 7 a post-workout protein?

It can be, but it is built for slow release. Pea protein and micellar casein digest over hours, so it suits between meals or before bed better than a fast whey isolate right after training.

How does it compare with Rule 1 whey?

Whey digests faster and usually carries more protein per scoop. Source 7 trades that speed for longer amino acid delivery and a dairy-light base, with no added sugar.

Does it contain lactose?

The base is pea protein and micellar casein, so it is not a whey product. Casein still contains milk protein, so it is not dairy-free; check the label if you avoid milk.

How much protein per serving?

22g per serving, with 0g added sugar and 1.5g saturated fat. Serving count per tub varies by flavor.

Is it third-party tested?

Yes. It is Informed Choice certified, meaning batches are screened for banned substances, which matters for tested athletes.

When should I take it?

Morning, between meals, or before bed all work. The slow blend is aimed at steady amino acid delivery rather than an immediate spike.
