This is Professor David Sinclair's discovery and proof that this herb promotes long living, energy and good health.His book "Why we age and why we don't have to"explains why this is so. I will continue to buy this as anti aging supplement as I feel it doing me good
This was a gift for my daughter in law.... who is obviously breast feeding my grandchild so my review is only anecdotal! She is really delighted with the product - so much so a second jar was requested! She reckons that she knows by her supply if she's forgotten to take a dose and is delighted with the difference it has made to her.
