So, just a few minutes ago, I became aware that for years Lecithin has been known to lower serum cholesterol. I had no idea this was the case. There are many studies supporting this, here's one for example from https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3065734/, summarized in the popular press here (https://www.medicalnewstoday.com/articles/319260.php)
It seems more likely that it was the choline that lowered my cholesterol, rather than the NMN or the PT. I didn't mean to confuse anyone by the omission; I just didn't think it was important.Lecithin supplements have also shown promise in lowering cholesterol. In a 2008 study, participants took 500 milligrams (mg) of soy lecithin a day. After 2 months, the average total cholesterol was reduced by 42 percent, and LDL cholesterol was reduced by 56.15 percent.
The reason why I was supplementing with the creatine and lecithin is from this podcast with Chris Masterhjohn: https://peterattiamd.com/chrismasterjohn/ [1:50:00]. Basically Chris says that if you have MTHFR problems (I'm homo for C677T), taking massive B3 (ie NMN) will further stress your methylation inadequacies. Since the choline cycle can prop up a substandard folate cycle and since creatine supplementation will avoid the need to deplete methyl groups for creatine replenishment, he recommends these for people with MTHFR deficiencies, especially if you're gonna experiment with NMN or NR.
