I recently had a stent and arterial blockage which more artery's heading for the same problem, so I have been scouring the internet for help.
So I came across the Pauling therapy which sounded amazing and gave me hope, so I did purchase their Cardio product which is 5000mg of Ascorbic acid and Lysene .... one point to note Ascorbic acid is not vitamin C it's a component of vitamin C.
If you actually look up what makes up vitamin C you will find that their are more components than ascorbic acid which are needed for absorption.
Anyway back to the background, I tried this for a few days and noticed I was struggling with right side pain - which I knew was my liver as have had meds before which can cause issues with liver if you have fatty liver syndrome. I immediately threw this stuff out.
I don't disagree with the concept from Linus Pauling but I am switching to a whole food Vit C rather than a chemically created ascorbic acid. I haven't got into the L-Lysene side but there are alot of foods I normally eat heavy in Lysene anyway.
Most opinions regarding arterial plaque and heart disease will lead you to a lifestyle change, to follow the Omega 3 diet and/or the 100% veggie diet for reducing Omega and reducing LDL - the bad fats.
I'm on the fence for the whole veggie diet but try to remain open minded, the Omega 3 thing however I am can't dispute at all as investigations have proven increasing Omega 3's is key to managing your health overall in addition to heart conditions.
Hope you find something that works for you and if the Pauling products work then great, but my experience was not good with them.
