  • • Those on a low-protein diet
MYTHS & FACTS
Myth: Pea protein is inferior to animal protein.
Fact: While animal proteins are complete, pea protein is still high in essential amino acids and can be effectively combined with other plant proteins to achieve a complete amino acid profile.
Myth: Pea protein causes digestive issues for everyone.
Fact: While some individuals may experience mild digestive discomfort, many find pea protein to be easier to digest than other protein sources, especially dairy.

04 / INTERACTIONS

Medicine interactions

  • Antibiotics· antibiotic

    High protein intake may affect the absorption of certain antibiotics.

    → Space out the intake of antibiotics and pea protein.

    MODERATE

  • Blood thinners· blood_thinner

    High protein diets can affect vitamin K levels, which may influence blood thinning.

    → Monitor vitamin K intake and consult with a healthcare provider.

    LOW

  • Diuretics· diuretic

    Increased protein intake may lead to dehydration if fluid intake is not adequate.

    → Ensure adequate hydration when using diuretics and pea protein.
