Owen, Just wanted to ask you a question...Is it the L-Lysine Powder that you take with the Vitamin C Powder together that helps your heart health?
Adding lysine to vitamin C is the Pauling/Rath invention for reversing heart disease.
You might review http://PaulingTherapy.com
Vitamin C is the necessary component (to keep arteries strong) but it is lysine (and proline) that together with vitamin C stop and seem to reverse the process of atherosclerosis. Together these are "Lp(a) binding inhibitors."
At the bottom of the first post, http://www.vitaminc.foundation/forum/viewtopic.php?f=11&t=11598, is the Pauling story of when and why he first recommended lysine to a fellow member of the national academy of science - the member with severe CVD had been taking vitamin C, but vitamin C alone did not resolve his heart condition.
