2 capsules daily cover the daily requirement

Your body relies on the daily intake of 13 to 16 mg of the sulfur-containing essential amino acid L-methionine per kg of body weight. At a body weight of 75 kg, for example, about 975 to 1.200 mg are needed daily. This means that a normal-weight person with two capsules of 500 mg each can cover his daily requirement in addition to the diet. If your eating habits are unbalanced and lead to a change in the intake and availability of L-methionine, you are on the safe side with the consumption of capsules.

Essential amino acids

L-methionine, which as a proteinogenic amino acid is part of many different proteins, cannot be produced by your body. The human metabolism is also unable to convert other amino acids to L-methionine, so it is considered essential and must be taken with the food.


L-methionine is of central importance for many metabolic processes and as a necessary component of many structural proteins. In addition, L-methionine is used as a raw material from which the body can if necessary also produce the amino acid cysteine through modification, if cysteine is not absorbed in sufficient quantity with the food.

Sulfur in hair and nails

The ZeinPharma L-Methionine Capsules provide you with valuable sulfur. Because the amino acid L-methionine is next to the L-cysteine (which in turn is formed from L-methionine), the only amino acid containing sulfur compounds.


L-methionine and cysteine are necessary constituents of many proteins because of their sulfur linkages, especially structural proteins that provide structure and firmness to individual cells and fascia, such as ligaments and tendons. Sulfur plays a role in normal fingernails, toenails and hair. The strength of these is related to the number of sulfur bridges in the keratin. The keratin forms the firm horn structure in hair and nails.

Methionine in the metabolism

With L-methionine you get the basic building block for proteins in your body. Because the amino acid is always the starting point for the construction of proteins. L-methionine plays the role of the so-called starter amino acid, thus forming the first building block of proteins. Subsequently, further amino acids are attached.


In its role as a cofactor, L-methionine in intermediary metabolism often plays the role of the methyl group donor for the synthesis of certain hormones and neurotransmitters, such as epinephrine and others as well as for the biocatalysts creatine, choline and histidine. In many intermediate metabolic processes, methionine is degraded and rebuilt. However, if necessary, the body is able to re-synthesise new L-methionine from the degradation residues of methionine. It is a kind of practical recycling.

High purity

With the L-methionine capsules of ZeinPharma® you get to 99 percent pure L-methionine. One percent foreign substances refer to the pure water from the manufacturing process which has no effect on the bioavailability of L-methionine. You can consume the methionine capsules of ZeinPharma® at the recommended dosage without any hesitation.

Vegan and natural

If you have no or only a few methionine-containing foods in your diet, supplementation with the capsules may be useful and helpful. In case of an overdose, which is both theoretically and practically possible, with the simultaneous consumption of capsules and foods with a high L-methionine content, you do not have to worry about complications; because your body easily breaks down the excess methionine and uses the breakdown products as far as possible for other metabolic processes.


The L-methionine capsules of ZeinPharma® are also suitable for vegans and vegetarians. For the production of the amino acid L-methionine only raw materials of non-animal origin are being used. The capsule shells contain no ingredients of animal origin. They are made of pure vegetable cellulose, not gelatin, which is made from animal products like the capsule shells of other manufacturers.

Safe - no impurities

With the L-Methionine Capsules you get a completely safe and pure product. ZeinPharma uses only certified raw materials for the production of L-methionine, which are constantly controlled for contamination. ZeinPharma attaches particular importance to the fact that the L-methionine capsules contain no residues such as heavy metals or microorganisms. Only when the raw materials have passed all analyses and quality controls regarding purity without any objections, they can be used to manufacture the capsules.
