I take arginine powder, which is a vasodilator, helping
keep blood vessels wider.
However the top recommendation I can make is
Undenatured whey powder!
When taken without using heat or blenders,
cysteine, glycine, and glutamate which are amino-acids naturally present in the whey powder, become Glutathione precursors.
Glutathione, a tri-peptide, happens to be the Master-Anti-oxidant and it can contribute to our good health and wellness, more than anything else available to us.
When in adequate levels in the body, it helps keep the JNK gene inactive. The JNK gene's activation, initiates the signalling of disease processes:
Diseases like Cancer, Alzheimer's, Autoimmune conditions, Parkinson's, Diabetes and so on.
I take 40 grams of undenatured whey isolate powder daily with milk, mixed in a sports blender-bottle (manual-not electric)

I hope this helps,
