Many of you will know of Linus Pauling's work linking heart disease to chronic scurvey. Vit C is good on its own, L-Arginine is good alone too, but a drink mix of 4-5 grams Arginine and 2-3 grams of Vit C shaken well in some Water Cure d me of two months of severe chest pains and other symptoms very very quickly. I call it a near miracle.
Hawthorn and Cayenne, a supposed miracle combo, hardly helped at all.
Im afraid I don't have time to go into the Science behind this but there are a lot of testimonials out there. No need to buy expensive products, I get standard bulk L-Arginine.
I now take 10+ grams of L-Arginine per day, some people take up to 20 g's. 5-10 grams of Vit C too...
Good Luck all, I hope this helps at least one person.
