But why not to use gelatin directly? [calf´s foot gely directly]
I do not like the idea to use an isolated aminoacid;[/QUOTE]
What you're looking for is the methyl groups not the glycine, I was just pointing out that this supplement is best because glycine has none of the unwanted side effects that can occur with other vitamins/amino acids...for example supplementing with methylfolate means your getting some methyl groups in there but you have to take in a bunch of folate, if you're deficient that might be great but excess folate consumption can cause cancer...glycine is the most simple amino acid and is safe in huge doses, it's physiological effects are limited, it has a calming effect if anything...1-2g of glycine a day won't make a considerable physiological change...look up studies for Betaine supplementation it's been found to be safe even in high doses...
