L-Methionine is an essential amino acid, which means that it cannot be manufactured by the body and must be obtained through the diet or by supplementation. L-Methionine supports the production of the cellular radical scavenger glutathione, and thereby assists in natural detoxification processes. In the body, L-Methionine can also be converted into SAMe (S-Adenosyl Methionine), a compound that supports healthy joints. Furthermore, the human body relies on ingested sulfur amino acids, such as L-Methionine, for the synthesis of protein, as well as for biologically active sulfur.

Suggested Use

Take 2 capsules daily as needed, preferably on an empty stomach. Do not exceed the recommended daily dose.

Other Ingredients

Gelatin (capsule), magnesium stearate (vegetable source) and silica.

Not manufactured with wheat, gluten, soy, milk, egg, fish, shellfish, or tree nut ingredients. Produced in a GMP facility that processes other ingredients containing these allergens.

Natural color variation may occur in this product.

Caution: For adults only. Consult physician if pregnant/nursing, taking medications (especially antidepressants), or have a medical condition. L-Methionine may increase the blood levels of homocysteine in some individuals. Keep out of reach of children.

I was tested with Kinesology with this and it was a great supplement for me

Some supplements from iHerb are not tested with strict policy, its just how it is, so you do run a risk of it not being the product you want. But in this case this is a terrific product in this brand. Other brands they sell I don't know about.

Thanks for your feedback!

Seems to help with histamine intolerance

Posted by iHerb Customer on Apr 21, 2017 | Verified Purchase

I have dermatographia, a rare skin condition in the dermatology/eczema family. No doctor has been able to explain why I suddenly got it 3 years ago but I've been on daily anti-histamines ever since. After more research I now strongly believe it's a histamine intolerance - there is no arguing, my body is over loaded with histamine. These tablets manage to degrade histamine levels slightly, I can get 36 hours between anti-histamine tablets where normally I need them every 24 hours. Early days, I hope they can work better over time.

Thanks for your feedback!

quality NOW amino acid 500mg is a good choice ( I require 1500mg dosage) and it is a good size for ease of swallowing ( not a horse tablet!! )

Thanks for your feedback!
