ChefT, I tried to include some scholarly articles referencing research for nutritional supplementation of r-alpha lipoic acid (shown to support neuropathy in various metabolic and other mechanisms), and sunflower lecithin (shown to support brain cell integrity), however I received a message blocking my post due to new members being unable to share links for an unspecified timeframe.
The article titles are: Insights on the use of a-lipoic acid for therapeutic purposes (doi 10.3390/biom9080356), and Top 8 sunflower lecithin benefits and uses, published on Healthnews dot com, dated April 28, 2023.
I found them informative, and the references supporting the article are included at the end.
I also am investigating other nutritional methods of supporting the unique symptoms that accompany MGUS/SMM, with other quality and researched nutrients, and if I find further info I’ll list it here (hopefully I’ll be able to share links soon).
