@Sara I’ll reply one by one below:
Resveratrol is a potent antioxidant therefore it can help reduce inflammation in the body, which you’ve noticed on your skin.
NAC vs Glutathione
Glutathione is made from 3 amino acids: glycine, glutamine and cysteine. NAC (or N-acetylcysteine) is made from cysteine (and is dependent on vitamin B6) that can be used by the body to make glutathione. Glutathione is a powerful antioxidant particularly concentrated in the liver.
The OAT test has a marker called N-acetylcysteine. If this marker is low, it means that you either
don’t produce NAC or
it is being used up because there is an increased need for NAC or
both!
Do we need both? The advantage of supplemental liposomal glutathione is that you know you are getting in glutathione in an absorbable form. NAC still needs to be converted to glutathione, but in a lot of cases, it does help raise glutathione. To form glutathione, you still need the other amino acids and cofactors. If someone is vegan, has poor digestion affecting protein breakdown, has malabsorption issues, is exposed to mold/toxins, etc., glutathione may be a better choice.
In terms of NAD (Nicotinamide Adenine Dinucleotide), I encourage you to watch this video inside the Mold & Mycotoxin Illness course about mitochondrial health to better understand where it fits into the whole picture of how the cell functions (cellular metabolism) and the Electron Transport Chain where cellular energy is produced.
Glutathione does help neutralize free radicals and detoxify harmful substances in the liver, potentially reducing the oxidative stress caused by heavy alcohol consumption.
Some studies suggest that glutathione or its precursors (such as N-acetylcysteine, which boosts glutathione levels) can mitigate alcohol-induced liver damage. But ultimately, the best way to avoid liver damage is to reduce/eliminate alcohol altogether.
