NAC: Treating Apnea that contributed to AFIB

After trying 0, 1/4, 1/2, and 1 teaspoonful of NAC (n-acetyl-l-cysteine powder) at bedtime, my AHI (pulse oximeter adjusted index) has dropped significantly.

It is tart to me so I mix it with warm honey water.

Tolerance of NAC & impact on AHI probably will vary greatly depending on individuals; only way to find out is to try it; just **beware** that NAC does THIN your blood; I wait over 3 hours after my 5mg of Eliquis before taking NAC.

Self-hacked site has nice summary on NAC benefits.

Next experiment is adding glycine to see if it helps or not (glycine is needed in Glutathione synthesis).

What is the view of your consultant regarding what you are taking?

As for consultant's view, not sure; however (a) specialists around here they are not the best & (b) too recent of a development & (c) my bodily empirical response speaks the loudest & (d) risk of drug interactions are minimized by slow gradual increase in dosage after Google/Youtube searches; you are rightfully cautious, please do consult with whomever you trust before trying NAC if you do indeed have apnea; just sharing what works for me specifically.

Yes I have sleep apnoea, diagnosed 7 years ago, interesting info.

I'm sorry but I've no idea what this is so can't make a helpful reply!

I take NAC and L-glycine every night before bed. I think it helps sleep - not sure whether it affects my AF or not. No NHS practitioner I’ve met has heard of these sorts of supplements, but I do a lot of online research before I try things and go slowly to check out any effects.

May I ask what is your proportions of NAC relative to Glycine (like 2mg NAC per 1mg of Glycine)? My Glycine will be arriving this coming Friday.

#2

How do you measure the impact/effects?

In my case, I use SPO2 assistance with pulse oximeter nightly.

I noticed my O2 level flattens above 95 for over 3.5 hours duration with NAC.

Before NAC, apnea events occurs after ~2 to 2.5 hours.

The ratio of NAC to L-glycine that I’ve found most commonly recommended is 1:4. For example 50mg NAC to 200mg glycine. I take this, or sometimes up my dose of NAC a bit. I’ve been treating various auto-immune and other conditions for 30 years, both by myself and with a functional doctor, so I use a combination of research, medical professional input, intuition and self-observation.
