PREVENTION: If you are otherwise healthy with no known genetic pre-disposed risk of heart disease in your family tree, then you would want to consider:
3000 mg/ (1 gram) of vitamin C per day, along with 1000 to 2000 mg of an essential amino acid (L-Lysine) and possibly 500 mg to 1000 mg of a non-essential amino acid (L-Proline)
MILDLY THERAPEUTIC: If you do have heart disease or stroke in your immediate family and in your gene pool (I.E) Mother, father, sister, brother has had a heart attack or stroke or diagnosed with heart disease)
3000 to preferably 6000 mg of Vitamin C each day and 2000 to 3000 mg of L-Lysine along with 1000 mg of L-Proline
THERAPEUTIC: If you yourself have had a heart attack or stroke and/or signs of heart disease then:
6000 mg of Vitamin C (MINIMUM) and up to 8000 mg or more along with 4000 to 5000 mg of L-Lysine and up to 2000 mg of L-Proline.
In addition depending on what site you visit additional nutrients of benefit include Vitamin E, Vitamin D3, CO-enzyme Q10, magnesium Omega 3 fatty acids, and others.
I am currently on 8000 to 10,000 mg of vitamin C (From a product called C-salts / SEE my other posts of types of vitamin C), I also take 4000 to 5000 mg of L-Lysine either by tablet form along with 1000 mg of L-Proline. (I usually also drink a WHEY protein shake every day which contains all the amino acids and the one I use has apprx 1600 mg of L-Lysine and 1100 mg of L-Proline)
(There are cautions on different sites and in my many blog posts of this subject of NOT jumping into mega doeses of vitamin C if you are on some sort of blood thinner.) Blood thinners would be considered coumadin, plavix, even 81 mg aspirin a day therapy, and could include (BUT NOT LIMITED TO) warfarin, heparin, lovenox, fragmin, eliquis, pradaxa, xarelto.
ANOTHER CAUTION is too much Vitamin K from otherwise healthy GREEN SMOOTHIES , green leafy vegetables etc.
PLEASE consult with your doctor, cardiologist, or naturopath etc. BEFORE TAKING HIGH DOESES OF VITAMIN C IF ON ANY SORT OF BLOOD THINNER REGIMEN.
