L-Methionine
Key Notes on Sources of L-Methionine Bioavailability: L-methionine from animal sources is more bioavailable than plant sources due to the absence of antinutritional factors and balanced amino acid ratios. Vegetarians/vegans can improve bioavailability by combining plant sources (e.g., soy + quinoa) to complement amino acid profiles. Industrial Purity: Food-grade and pharmaceutical-grade L-methionine (from chemical synthesis or fermentation) has a purity of ≥98%, meeting safety standards (e.g., FAO/WHO, GB 2760) for human consumption. Feed-grade products may include DL-methionine or lower-purity L-methionine, which is cost-effective for animal use. Dietary Balance: L-methionine works synergistically with other sulfur-containing amino acids (e.g., cysteine) and B vitamins (e.g., vitamin B6, folate) in metabolism. Excessive intake (e.g., >1g/day from supplements) may lead to hyperhomocysteinemia, so intake should be balanced with dietary sources or guided by nutritional recommendations.
