Body composition evidence brief
Rice protein powder is a plant-based protein option often used by people avoiding dairy, soy, or pea protein. It is commonly promoted for muscle gain and recovery when total protein intake is the limiting factor.
Rice protein can support training when enough protein is consumed, but the evidence base is smaller than whey and dose quality matters.
8-week RCT: 24 g/day rice or whey produced similar lean-mass, FFM, bench, and leg-press changes.
Larger servings or blends may be needed to match essential amino acid and leucine density; scoop weight alone is a poor comparison.
Heavy-metal testing, amino acid completeness, and serving-size math are central to judging rice protein products.

The score reflects evidence that the supplement does its stated job. Some jobs are direct, such as strength, endurance, or recovery; others are indirect, such as sleep, mood, appetite, or health support. A real effect can still receive a cautious practical rating when dose, safety, product quality, or audience fit remain uncertain.
