Why It Works

Key Benefits

💪
Plant Protein Blend
The label lists fava bean protein isolate and YESTEIN fermented nutritional yeast protein, with 20 g of protein per serving (2 scoops, 35 g; 24 servings per container). In a meta-analysis of 49 trials, protein supplements added to resistance training were associated with small gains in strength and muscle size, with no further gain in fat-free mass once total protein intake passed about 1.6 g/kg/day (about 112 g a day for a 70 kg adult). Those trials did not test this product, and their abstracts do not give supplement doses. The label gives no amino acid profile.
🌱
What Studies Show on Plant Protein
A meta-analysis of 16 trials found no difference between plant and animal protein in changes in absolute lean mass or muscle strength, but animal protein was favored for percent lean mass, especially in adults under 50. No trial of fava bean protein isolate on muscle was found; one 6-month trial of yeast protein in older adults found improved physical function, with no difference between groups in muscle mass or handgrip strength. The abstracts of the meta-analyses do not give doses, and it is not stated that the yeast protein in that trial is the one in this product.

Science

Clinical Evidence

Published research relevant to this product. These studies were generally not conducted on this specific product.

🔬
A systematic review and meta-analysis of 49 randomized trials (1,863 participants) found that dietary protein supplementation increased gains in strength (2.49 kg in one-repetition-maximum), fat-free mass (0.30 kg) and muscle size during resistance training of 6 weeks or more in healthy adults. The effect on fat-free mass was reduced with increasing age, and protein intakes above about 1.6 g/kg/day gave no further gain. This product provides 20 g of protein per serving; the abstract does not give the supplement doses used in the trials.
Morton RW et al. Br J Sports Med, 2018;52(6):376-384. ↗
🔬
A systematic review and meta-analysis (16 trials in the meta-analysis) found that protein source (animal or plant) did not affect changes in absolute lean mass or muscle strength. Animal protein favored percent lean mass, and adults under 50 gained 0.41 kg more absolute lean mass with animal protein.
Lim MT et al. Nutrients, 2021;13(2):661. ↗
🔬
In a randomized trial of 92 Chinese older adults, 6 months of daily whey protein or yeast protein improved 6-m walk speed and Short Physical Performance Battery scores compared with no supplement, with no differences between groups in appendicular skeletal muscle mass or handgrip strength. The yeast protein used is not stated to be the one in this product.
Huijing B et al. Food Sci Nutr, 2026;14(3):e71552. ↗
🔬
A meta-analysis of 22 randomized trials in adults without chronic kidney disease found that high-protein diets increased estimated GFR (which the authors say may reflect short-term hemodynamic adaptation) and did not significantly change serum creatinine, without consistent biochemical evidence of kidney injury; most trials were short and relied on creatinine-based estimates, so long-term kidney effects remain uncertain.
Teixeira Silva PR et al. Diabetes Obes Metab, 2026;28(9):7672-7683. ↗
🔬
A systematic review of dietary protein intake and risk of bone disease, kidney disease and sarcopenia found the overall evidence insufficient; only one randomized trial addressed kidney disease in adults and showed no significant effects.
Lamina T et al. Curr Dev Nutr, 2025;9(3):104546. ↗
🔬
A prospective cohort of 236 children hospitalized with acute hemolysis due to G6PD deficiency found that fava bean ingestion was the documented trigger in 51.6% of episodes, and that fava bean-induced hemolysis was more severe. The study concerned fava beans as food, not fava bean protein isolate.
Prashanth GP et al. Pediatr Blood Cancer, 2025;72(5):e31609. ↗
🔬
A 2026 narrative review on preserving lean mass during GLP-1-based obesity treatment concluded that protein supplementation and nutritionally complete meal replacements may be useful when intake is insufficient. It describes the evidence for supportive strategies as mainly indirect.

Science behind this product

Protein supplements and muscle: A meta-analysis of 49 randomized trials (1,863 healthy adults) found that protein supplementation increased gains in muscle strength, fat-free mass and muscle size during resistance training lasting 6 weeks or more. The effect on fat-free mass was smaller with increasing age, and no further gain was seen once total protein intake exceeded about 1.6 g per kg of body weight per day. These trials did not test this product. Morton 2018

Plant versus animal protein: A meta-analysis of 16 trials found that protein source (animal or plant) did not affect changes in absolute lean mass or muscle strength, although animal protein was favored for percent lean mass, especially in adults under 50. Lim 2021

Fava bean and yeast protein: No trial of fava bean protein isolate on muscle outcomes was found in PubMed. In one 6-month trial in 92 Chinese older adults, yeast protein and whey protein each improved walking speed and physical performance scores compared with no supplement, with no difference between groups in appendicular muscle mass or handgrip strength; this was not the same product. Huijing 2026

Protein and the kidneys: A 2026 meta-analysis of 22 trials in adults without chronic kidney disease found that high-protein diets increased estimated GFR and did not significantly change serum creatinine, with no consistent biochemical evidence of kidney injury; most trials were short and relied on creatinine-based estimates, so the long-term effects are uncertain. A 2025 systematic review found the evidence on protein intake and kidney disease insufficient. Ask your clinician for your protein target if you have kidney disease. Teixeira Silva 2026 · Lamina 2025

Fava beans and G6PD deficiency: Fava bean ingestion is a recognized trigger of acute hemolytic episodes in people with G6PD deficiency. Whether fava bean protein isolate triggers hemolysis was not established in the sources found, so people with G6PD deficiency should ask their doctor first. Prashanth 2025 · Tesfamariam 2026

Protein amount versus the trials: In the 49-trial meta-analysis above, adding supplemental protein gave no further gain in fat-free mass once total protein intake passed about 1.6 g per kg of body weight per day, which is about 112 g a day for a 70 kg adult; one serving of this product provides 20 g of protein. The abstracts of that meta-analysis and of the plant-versus-animal protein meta-analysis do not state the supplement doses used, so this page cannot compare a serving with the doses in the trials. Morton 2018
