I've been using lysine for a long time and only recently found that some people are reporting angina they think is related to using too much lysine. So, I thought back over the past several years. In the past 10 years, I've had occasional angina. But for the past several years, haven't had any.
But, lately, I'd been upping the lysine to around 2000 mg a day. Some days more.. And occasionally, I felt the pain again. So, I decided to use just 500 mg daily. A compromise. Anyway, just my experience and my present decision on my dosage.
Lysine is an antagonist to the Nitric Oxide substrate Amino Acids like Arginine/Citrulline. Perhaps that contributes to heart issues.
