The abstract describes the “single specific amino acid” as being cysteine, which we can get from food and was believed to also be readily made by our bodies, but recently was found to be restricted in its creation by aging.

Other amino acids we stop properly making include glycine and taurine. Together, supplementing these three amino acids has been found to allow our bodies to again make glutathione and superoxide dismutase (SOD), the two key antioxidants we have plenty of, as children.

These studies were previously posted here on Free Republic under “GlyNAC” and “Taurine” in the titles and keywords.

The form of Vitamin A in the essential step is a heavily converted form our bodies make from Vitamin A.

And yet we are supposed to believe all these mechanisms are just an accident of evolution, without a Creator to guide the processes from the very beginning..........................

I recently started taking two grams each of glycine and nac —three times a day.

This combination has significantly increased my feeling of health and well being

I’ve not read of any upper limits for the safe intake of glycine much below 10 grams daily

However, the literature generally limits the safe intake of NAC to only 2 grams daily. However, the only study on unsafe NAC limits I’ve seen were at about 10 grams daily and that was outlier.

Have you read about any safe upper limits to NAC daily intake.

Appreciate the data streams.

your comment is the first I’ve read of superoxide dismutase (SOD).

do taurine and cysteine individually increase SOD or do they work together like gly/nac work together to increase glutathione

Can you post more on that.

I did not know that our cysteine and taurine levels decline with age.

How much cystein and taurine do you recommend as a daily supplements.

Glutathione levels drop with age. But also auto immune and chronic diseases as well as high bmi push glutathione levels lower.

Have you seen that these diseases also lower cystein and taurine levels—and therefor SOD— beyond what aging does?

Other amino acids we stop properly making include glycine and taurine.

I've been taking 3,000 mg of Taurine a day for many years now. I believe it's improved my vision.

do NAC and vitamin a work independently to improve the eyes or do they work together to improve the eyes.
