Vegans and vegetarians are at increased risks for L-cysteine deficiencies because as a natural compound it is found primarily in foods like red meats, seafood, poultry, dairy products and others that are not suitable for animal-free diets. Vegan L-cysteine is available, wholly derived from plant sources, but it is costly, especially when compared to non-vegan products and you would have to read the makers descriptions to discern this. If the label is not specific and does not mention Vegan or plant sources then look for one that does. This product, which I would recommend to most, states on the label “not manufactured with wheat, gluten, soy, milk, egg, fish, shellfish or tree nut ingredients” – however, red meats and poultry are not mentioned in that statement.
