Buying Guide
What should vegetarians consider when choosing protein tablets or powders?
- Protein source: algae (chlorella/spirulina) for greens and B vitamins, or pea protein for complete amino acids and higher protein per serving.
- Amino acid profile: look for products with essential amino acids and, if possible, B-12 if you follow a completely vegan diet.
- Form factor: tablets may be easier for some; powders offer mixing flexibility but require preparation.
- Allergens and additives: check for dairy, gluten, soy, artificial colors or flavors if you have sensitivities.
- Absorption and bioavailability: products with broken cell walls or added vitamins may improve nutrient uptake.
- Intended use: daily greens and B-12 support vs. high-protein shake supplementation for workouts.
