About form
Form is Rain’s protein powder and the only product in the range that carries an approved health claim without detours: protein contributes to a growth in muscle mass and to the maintenance of muscle mass. At 20 grams per serving, form sits well above the threshold required for that claim.
The protein comes from four plant sources: pea, hemp, chia and sacha inchi. Blending several sources is common practice in plant protein, because the amino acid profiles complement one another. Pea protein is rich in lysine but lower in methionine, while hemp and sacha inchi contribute a broader profile. Each serving provides 20 grams of protein and zero grams of sugar.
Form is free from soy and gluten and is also available in vanilla flavor. One package provides 15 servings.

BCAA stands for branched chain amino acids, that is leucine, isoleucine and valine. In form they are not added separately but come naturally from the plant protein, more than three grams per serving. The serving also contains all nine essential amino acids, the ones the body cannot make itself and must get from food.
