A must have highly beneficial quality product to supplement anyone's diet during these times of viral infections.(Take 600mg – 1000mg per day, or up to 3 times per day for severe illness)NAC (N-acetylcysteine) is a precursor ingredient to glutathione, and also has direct effects related to the coronavirus and the spike protein. It has antiviral and anti-inflammatory effects and counteracts excessive immune reactions. It also protects against lung damage and blood clots.NAC has been discontinued on Amazon and Walmart.It is the one main product that is necessary to boost lung health. This really helps fight off a lung infection. It is usually in short supply, so if you see it, get it!!

Part of my reversing grey hair protocol...
14 December 2022

I use several supplements to combat early grey hairs.WHAT IS N-ACETYL-L-CYSTEINE? As a dietary supplement, N-acetyl-L-cysteine supports comprehensive health in a variety of ways, including promoting normal liver function. NAC is a powerful antioxidant that protects cells from oxidative stress.So as you may know the cause of grey hair is caused by the weak liver that does not want to convert the hormones so more strain is out onto the thyroid and as a result, the hair can go grey. This helps to fight off free radicals. This has no taste, size is ok not too big but not small either - standard capsule.The vegetarian capsules are much easier on the stomach than the standard amino acid capsules. This supplement indeed has many benefits

Very good NAC
31 January 2022

When you open the bottle it has that characteristic sulfur smell that rotten eggs have. Can be a bit overpowering for some people but if that is the case then just hold you breath and chug it down with some water. I remember the first time I took a NAC supplement. It gave me such a massive amount of energy., though I never felt it so much after that. It's one of those rare supplements that I really noticed taking. Another one that I really noticed and that gave me a lot of energy is Dragon Herbs High Mountain Shilajit. And the effects are even more pronounced when you are fasting, detoxing or just eating light and healthy food. The energy comes from the replenishment of the glutathione in the body and as I said it's noticeable. NAC is also a very good antioxidant ... MoreWhen you open the bottle it has that characteristic sulfur smell that rotten eggs have.

It benefits the respiratory system and the immune system as well. It's good for the liver too. It's also good for getting you sober fast, but please don't let this be an excuse and go for some crazy drinking. I have read that some toxicology departments it the hospitals give NAC to their intoxicated patients to get better. Stay safe and healthy and may God bless you!
