Common dosing range
amount needed to help reach ~0.8–1.6 g protein/kg/day

Weeks (as part of overall protein intake)
Watch out for
People with G6PD deficiency should avoid fava-derived products (favism risk)
What is it
Broad bean (faba bean) protein is a plant protein concentrate or isolate made from Vicia faba, used as a vegan protein ingredient in powders and foods. It offers a legume amino acid profile, relatively high in lysine but lower in methionine, similar to pea protein. Evidence is largely general protein-intake data rather than faba-specific clinical trials.

meeting dietary protein needs
Supplement benefitFaba bean protein supplies a legume amino acid profile and can contribute to daily protein requirements, supporting muscle maintenance when total intake is adequate. Faba-specific outcome trials are scarce, so its role is inferred from broader plant-protein evidence.
Bottom line: A practical vegan protein source for meeting protein needs, with little faba-specific clinical data.
How to take it
- Typical dose
- enough to help reach daily protein targets, e.g. 15–30 g per serving
- Timing
- any time; around training if used for muscle support
- With food
- either, often blended
- How long to try
- ongoing as a dietary staple
What to track
- total daily protein intake
- GI tolerance
- satiety
Safety
Common side effects
bloating, gas
Serious risks
- hemolytic reaction (favism) in G6PD-deficient individuals
Who should avoid it
- people with G6PD deficiency
- people with legume allergy
Pregnancy & breastfeeding
Likely fine as a food-grade protein for those without G6PD deficiency; choose tested products and consult a clinician.
Choosing a product
Look for
- states protein content per serving and amino acid profile
- clear faba/Vicia faba sourcing
- third-party tested for contaminants
Be skeptical of
- implying superiority over other proteins without data
- muscle-building guarantees beyond adequate protein intake
- unverified 'clean' or detox marketing
