Should Amino NAC be taken with Selenium?

Amino NAC be taken with SeleniumQ:  I have heard that Amino NAC should be taken with Selenium – 100 mcg with each Amino Nac capsule.  Do you advise this and if so what is the reason?

A: It is good to be getting selenium with your diet (i.e. liver, meat, grains, if eaten) and supplements when taking NAC.  NAC can be taken for many different reasons, but one thing it does is help increase the body’s production of glutathione.  Glutathione and vitamin E work to catalyze the conversion of organic peroxides to organic hydroxy acids through a selenium dependent enzyme called glutathione peroxidase.  This process is also used to then can be used to neutralize lipid peroxides as well.  These peroxides are free-radicals which can damage cells.

Selenium doesn’t have to be taken with a NAC at the same time, but it is good to be getting it in sometime during the day.  Recommended doses for women are 55 mcg / day and for men is 70 mcg.  Higher dosed can be taken, especially in those who have low antioxidant status (which is most adults, but can determined through lab testing), but doses that exceed 200 mcg per day has been found to be the lowest observed adverse effect level for selenium, so for some it may be good not to go over that amount or a person may have negative intestinal effects.

There is some positive research on male infertility and using 600mg of NAC + 200 mcg of selenium per day to improve semen quality.  One major study limitation was that the analysis did not include the pregnancy rate, which makes it difficult to conclude if increases in sperm quality would in fact affect fertility.

We do carry a Selenium + Vitamin E supplement with Genestra.

Each Tablet Contains

  • Vitamin E (d-alpha tocopheryl succinate) 200 IU
  • Selenium (as selenomethionine) 200 mcg

I would recommend 1/2 tablet with each NAC supplement you take.
