I already had some NAC and glycine. Do you think this would work as well as glutathione?
BTW I take stearic acid in the morning with some yogurt. As I mentioned before my BP has been surprisingly low recently. It was 114/74 a few minutes ago. I don't think I've ever had a reading that low. I don't know if it was the SA but at least it doesn't raise it.
Let's make the calculations, they are easy.
Molar mass NAC = 163.19 g / mol
Molar mass of glycine = 75.07 g / mol
The study was conducted in humans. Their weight is not specified, but it is indicated how much they consumed both substances:
"OAs were provided capsules of glycine (1.33 mmol / kg / day) and cysteine (0.81 mmol / kg / day, provided as N-acetylcysteine [NAC]) prepared by a licensed pharmacist, and replenished every 4-weeks for 24-weeks . "
Let's calculate for a body weight equal to 70 kg:
For NAC: (0.81 * 70/1000) * 163.19 = 9.25 grams
For glycine: (1.33 * 70/1000) * 75.07 = 6.99 grams
This is a very high dosage, much higher than the commonly used dosage.
How did the concentration of reduced GSH change? The study says:
"Compared to YA controls, RBC concentrations of reduced-GSH in OA were 76% lower, and plasma TBARS and F2-isoprostane concentrations were 845% and 318% higher, respectively (Table 2) (Figure 2). GlyNAC supplementation was associated with a 200% increase in RBC concentrations of reduced-GSH, and 75% and 74% decline in TBARS and F2-isoprostance concentrations respectively. "
So your dosage is unlikely to be as high.
