Now L-Lysine is a Pharmaceutical Grade essential amino acid.

L-Lysine is an essential amino acid that must be obtained through the diet or through supplementation. Lysine is necessary for the production of all proteins in the body, and is required for the maintenance of the structural proteins collagen and elastin, which form all connective tissue such as skin, tendon, and bone. L-Lysine is also a precursor to L-carnitine, which is needed for fat metabolism and energy production. In addition, L-Lysine may help to support a healthy immune system and proper cardiovascular function.

Suggested Use

Take 1/4 level teaspoon daily.

It isn´t just vitamin C that your arteries and blood need

Posted by Reviewer2725717 on Jan 06, 2017

My advice to all those weight conscious people who limit their calories as they age, is to support your arteries with Lysine as well as vitamin C. Lack of Lysine may be a factor in age related slower healing. My informal studies in CardioRetinometry®, greatly obstructed by the UK NHS, protecting profits before people (and pharmaceutical dirty tricks) seem to show that it helps just as Linus Pauling and Matthias Rath predicted it would. CardioRetinometry® as and when research funding allows and more doctors qualify in the speciality, will reveal far more about the benefits and risks of different foods, nutrients, environmental stresses and fill the vacuum of a black hole in medical research that plainly threatens pharmacy profits which is why there are scant papers listed in PubMed. Try finding papers on the value of 20 grams of vitamin C - or even a danger. People don´t die of vitamins. They just live longer and too healthily to suit PharmacoMedicine. Eventually family doctors will realise they have been "conned" by their more clever pharmacy colleagues into thinking their incomes depended on sickness and drugs. When the penny drops, they will realise how they have lost fortunes because people want prevention not cures; will pay half what they pay Medicare for it; and it all goes to the doctor - not drug companies and insurers. Only CardioRetinometry can guarantee freedom from arterial disease and heart attacks. Why consult doctors who die of heart attacks? Mine don´t!

Bitter, but easy to take, and cheaper!

Posted by Reviewer2945633 on Dec 23, 2016

I think this is much cheaper than the pill form, which can be a bit like horse pills, to be honest. I have wondered if I will need Heimlich myself a few times with the 1000 mg pills. For this, just stir into a small amount of water, and swallow quickly. Helpful hint- add a bit of "Natural Calm" magnesium powder to it, and it all goes down without the bitter taste.
