Anecdotally there is a lot of testimonials online that high doses of Vit C combined with high dose Lysine helping with cardiovascular disease. I doubt Vitamin C alone will be of any help. Don’t know about Lysine and longevity though.
I agree, if there is one thing I regret it’s putting too much hope in things like diet/lifestyle/supplements. The only thing I probably did right and that was completely by accident with no thought for my heart was going on the estrogen patch at menopause. My 52 y/o SIL barely survived a heart attack recently and that was quite a reality check. I still eat a heart healthy diet and exercise etc but no longer think those alone are enough to protect me.
Simon Hill from “The Proof” podcast recently had a CT angiogram to determine his coronary calcium score and to see if any evidence of heart disease was present. This video is a detailed exploration of the test, his results, and a plethora of lipid related topics.
For context, in 2015 Simon had an LDL of 120 mg/dl - at that point he shifted to a plant-based diet. Within a year he had an LDL of 70-80mg/dl. It should be noted that Simon has a strong family history of CVD. Simon’s results included a clearly AI analysis.
The transparency and honesty in the video is very much apparent, and it includes a great discussion around plaque progression, cardiovascular/metabolic health blood test results, and input from Dr. Thomas Dayspring and Dr. Dan Soffer. I would encourage folks to check it out.
