Yes it's is the same. See here.Is N-acetyl-D-glucosamine the same as N-acetyl-Glucosamine? Im having problems finding it in the netherlands
N-acetyl-glucosamine combines an acetyl molecule with a glucosamine molecule. All they are saying is that if you have 750 mg of N-acetyl-glucosamine, then by weight 610 mg of that is glucosamine, and 140 mg of that is acetyl. (It's incorrect to call glucosamine an element though).Ok i did find one source. Its kind of weird on the front it sais: n-acetyl glucosamine 1500 mg, and in the text on the back it sais:contains per tablet: 750 mg N-Acetyl Glucosamine, of which 610 mg elementary glucosamine. What do they mean by this, is this ok?
(translated from dutch)
Do they mean there is onky 750-610=140 mg n-acetyl glucosamine, and the rest is 'elementary' glucosamine (what is that?)... But what about the 1500 mg statement on the front then?
Glucosamine is an anti-inflammatory compound, but cannot cross the blood-brain barrier (BBB) and get into the brain. By attaching an acetyl molecule to glucosamine, it allows it to cross the BBB. So N-acetyl-glucosamine is likely having an anti-inflammatory effect in the brain, which I think may be the basis of its anti-anxiety action. My biochemical guesses as to why NAG seems to work so well as an anti-anxiety agent are given at the bottom of this post.
And when I weigh them: little more that over a gram (1030 mg per tablet). Am I misunderstanding something here, or did they really screw up with what they put on the bottle?
A tablet will usually weigh a little more than its stated contents, because of the filler and binder materials placed into the tablet to hold it together.
By the way, I tend to buy my NAG from iHerb in the US. They have very low prices, and it takes just 3 or 4 days to get to the UK.
Where did you find arginine pyroglutamate powder, and why/how does it help? I can't seem to find it, only arginine (freeform). Does it have other names as well?
Arginine pyroglutamate in bulk powder can be bought at very good prices from these bulk sellers: purebulk.com and www.bulksupplements.com. I don't know of any other suppliers.
I have found other arginine-containing amino acid powders (such as arginine, di-arginine malate, or arginine alpha ketoglutarate) also have potent anti-anxiety effects, when taking doses in the range of 5 grams of powder. However, arginine pyroglutamate crosses the BBB more easily than other arginine powders, so it is more potent in the brain.
I am not really sure on the mechanism of action of the anti-anxiety effect I observed with arginine powders. One study found L-lysine and L-arginine together have an anti-anxiety effect in rats. And this study suggests that arginine may potentiate GABA neurotransmission. Note that drugs or supplement s that work on GABA tend to have a tolerance build-up (ie, after some days, their effects get less). So arginine pyroglutamate may best be used as a short term boost to an anti-anxiety regimen.
