Micronutrients & recovery

Men following vegan, vegetarian, fish-eater, and meat-eater diets exhibit significantly different plasma concentrations of lysine, methionine, tryptophan, alanine, glycine, and tyrosine, with vegans generally having the lowest concentrations of essential amino acids and highest concentrations of glycine.

If you are a man on a plant-based diet, your blood levels of certain amino acids (like lysine and methionine) will be lower than a meat-eater's, but your body maintains them at functional levels. You do not need to fear 'incomplete' protein; eating a variety of plant foods ensures you get what you need. Focus on overall dietary variety rather than specific amino acid pairing.
