The best way to remain young is to take anti oxidants.... it could be any food or supplement rich in that.
Shilajit --- just google it.
This is the world's richest natural source of anti oxidants that could delay aging by centuries.... this herb is most potent herbal supplement. As per ayurved there is no such disease that could not be treated using this herb.
Amla - just google it.
One of the best anti oxidants available. The vitamin C rich stuff makes you young.
Keeping the supplements apart... if you take lot of fruits daily u wont require anything for aging..
u take pine apple daily for sometime I can bet u, you could see the difference. Your skin would glow.
Collagen/ Bird;s best as per me is more commercialised these days especially among chinese ladies. I know many ladies at mid 30's who take alot of collagen and bird's nest. There are many other cheaper but more potent solutions available.
The best an ti aging thing is KEEP Smiling
