L-Methionine 100 CAPS - 500 MG

Write a review

The sulfur containing essential amino acid L-methionine is particularly important because it:


  • Assists in the breakdown of fats
  • Aids in maintaining healthy skin tone, well-conditioned hair, and strong nails*
  • Serves as an important antioxidant and detoxifying agent*

What is L-Methionine?

Foods found in the typical adult diet are often limited in their protein value due to a lack of sulfur-containing amino acids such as methionine [1]. L-Methionine (the most efficient form of this amino acid) has antioxidant values, works as a detoxifier, and is considered a protective agent, as it is involved with DNA methylation, synthesis, and repair [2].


How does L-Methionine Work?

S-Adenosyl methionine (SAMe), the first product in the breakdown of methionine, is a key metabolite that regulates the growth, death, and differentiation of liver cells [3]. SAMe can only be synthesized when methionine levels are adequate, and decreased hepatic SAMe biosynthesis is tightly related to all forms of chronic liver injury [3]. Therefore, methionine supplementation may aid in the maintenance and function of a healthy liver.

Likely due to the fact that L-methionine is used to create creatine, which provides muscles with short-term chemical energy, supplementing L-methionine may help patients reach a healthy body weight, and strengthen bone, especially when supplementation is combined with a regular exercise regimen [4].

Dietary methionine is also crucial for the health of the intestine and the immune system (specifically, gut-associated lymphoid tissue) during development and growth, and when the gut is in a state of inflammation [5, 6]. L-Methionine’s role in the metabolism of fatty substances also helps to support blood flow and function of healthy arteries [7].

Last, but not least, L-methionine is essential for the production of collagen, which is a primary component in connective tissues such as skin and cartilage [8]. Healthy tendons, ligaments, bone, hair, and fingernails also require synthesis of significant amounts of collagen. These anti-inflammatory and regenerative effects also support a role for methionine in general wound healing and recovery from injury or disease.


What are the Suggested Uses for L-Methionine?

  • To assist in the breakdown of fats, supporting clear arteries and healthy blood flow. *
  • To support collagen production, which may help to maintain healthy cartilage, efficient wound-healing, youthful skin tone, well-conditioned hair, and strong nails. *
  • To serve as an important antioxidant and detoxifying agent, providing the liver with SAMe substrate for healthy function and regeneration. *


Source Materials: L-Methionine is made by chemical synthesis. Cellulose for capsules is derived from softwood tree pulp. All ingredients are vegan and non-GMO.


Allergens:  According to information provided by our suppliers, these capsules are free of the eight major allergens as identified by the Food Allergen Labeling and Consumer Protection Act of 2004 (FALCPA): Wheat (gluten), eggs, milk, soybeans, fish, shellfish, peanuts, tree nuts.


Recommendations: Use as directed by a healthcare professional.


Precautions: Pregnant or lactating women and individuals taking prescription medications should consult with a healthcare professional before taking any supplement. Because about one-half of methionine is metabolized by the liver, methionine supplementation may be ineffective in alcoholic liver disease [9].
