I had forgotten about this thread. The original question was re antioxidents and skin protection in the sun. I should have replied that my absolute favorite for that dual role is astaxanthin. It is a great antioxident and at the same time doubles the time I can stay out in the sun. For the first time in 50 I repeat FIFTY, years, I have a tan. They call it the "King of the Carotinoids". Besides being some 500 to a 100X more potent than vitamin E, it really does enhance skin health and reduce ultraviolet skin damage. For me it ranks up there with Vitamin D, Omega 3s and Green Tea as a "must have" supplement for health and longevity.
There is a long article in Natural News about Astaxanthin, it's uses, dosage and their recommended source to find it. Google and you can find numerous additional sources. I take 4X 4mg gel caps ED. Its amazing my fair Irish skin just isn't burning like usual and I only use 4PF accelrant/lotion for protection. The link below is to a long monologue from Mike Adams the holistic "Health Ranger" as he calls himself. Let some of his hot air out and he often has some great info.
