Thought I'd check back in.
In my previous posts I was touting NAG for mental clarify. I'm still taking it and consider it a likely permanent part of my stack, but at the end of the day I still wasn't getting where I wanted to be. I have decided that inflammation is only half the battle (actually more than half), but that I really need some direct NMDA agonism as well.
As such, I have been taking glycine, and added sarcosine back to my stack. Good results at first, though they appeared to become attenuated over time. So, I added a supplement that I have used in the past to good effect but which is controversial for some: l-glutamic acid (glutamate). Combined with the other supplements in my stack, which I will list below, I am currently at a sweet spot. We'll see how consistent it is.
I'm not going to recommend that anyone take l-glutamic acid, simply because there is so much doubt out there as to its safety. It is well known that glutamate is neurotoxic under certain circumstances, though it is also absolutely key to cognitive function and is one of the primary neurotransmitters. Personally, I accept the risk in light of how effective it is for me and because there appears to be no evidence that it is harmful at reasonable doses. The closely related substance MSG has been extensively studied, and a panel of experts recently concluded that doses up to 16,000mg/kg are safe, which is an astronomical number. I have been dosing between 1,000 mg and 2,000 mg per day. I am sure that glutamic acid would be exactly the wrong supplement for some, particularly those suffering from more of an over-active mind, but for me it feels right.
So, my current stack, honed over 3-4 years, and which is as of today making me feel almost cured, is as follows:
-L-glutamic Acid: 1,000-2,000 mg daily
-glycine 10,000(ish) mg daily
-Sarcosine: 2,000(ish) mg daily
-methylfolate: 400 - 1,200 mg daily
-NAC: 500 mg, every other day or so
-Quercetin: 1,000 mg daily
-NAG: 700 mg, every other day or so
-Vitamin D: 5,000-10,000iu per day (correcting a deficiency)
-Multivitamin
I am still fascinated to try BH4, especially after hearing about Chadwick's success, and I hope that it becomes more readily available soon. BH4 seems to be implicated in all of the symptoms I complain of, and I have a feeling it could be related to my issues.
