What is Doctor's Best Stabilized R-Lipoic-Acid?
Alpha-lipoic acid is a sulfur-containing fatty acid that performs vitamin-like roles in the body but since the body produces lipoic-acid on its own, it is not classified as a true vitamin. It functions as a co-enzyme in the metabolism of carbohydrates and is required for synthesis of acetyl CoA, a key metabolite in the cellular process that turns glucose (blood sugar) into energy. Stabilized R-Lipoic Acid contains Na-RLA, the sodium salt of R-Lipoic acid. Pure R-Lipoic acid is a very unstable molecule that has a tendency to polymerize with exposure to heat, light, and moisture. Na-RLA is a stabilized form of R-Lipoic acid that won't degrade at high temperatures.

How does it work?
Lipoic acid is a key factor in the cellular process that metabolizes glucose for energy production. Aging is accompanied by a decreased ability of the liver to recycle ascorbic acid following oxidative stress. R-lipoic acid, has been shown after two weeks of supplementation to aged rats, to reverse the age-related impairment of ascorbic acid recycling and concentration in liver cells. Aging is also associated with oxidative stress in the brain. The brain's high rate of metabolism and its long-lived neurons make it particularly vulnerable to oxidative stress. Since lipoic-acid interrupts cellular oxidative processes in both its oxidized and reduced forms, it plays a modulatory role in the brain and nervous system.

Why should I take Doctor's Best Stabilized R-Lipoic-Acid?
An ideal antioxidant would have the ability to quench a wide variety of free radicals, to support the functioning of other antioxidants, to bind or "chelate" metal ions that can generate free radicals, to function in watery and fatty environments and to be present in a variety of tissues, cells, and extracellular spaces. Lipoic-acid meets all of these criteria and is often termed as "the universal antioxidant." As we age, our ability to synthesize alpha-lipoic acid decreases. Age also brings an accumulation of oxidized proteins that interfere with mitochondrial efficiency and Alpha-lipoic acid addresses this situation. Alpha-lipoic acid comes in two forms, designated as "R-lipoic acid" and "S-lipoic acid." R- and S- lipoic acid are enantiomer isomers--molecules that appear as mirror images of each other. R-lipoic acid is naturally synthesized by humans, animals, and plants.

Protect your skin
Size: 6 Ounce (Pack of 2), Style: SPF 50
I really like this sunscreen spray. It’s easy to apply, dries quickly, and doesn’t feel greasy on my skin. The SPF 50 protection works great, even when I’m outside for a long time. It also stays on well when I sweat or get in the water. Overall, it’s a reliable and convenient sunscreen that I’d definitely recommend.

Awesome value for quality Banana Boat sunscreen
Size: 24 Ounce (Pack of 1), Style: SPF 50
Inside the package you get 2 sprays and 1 lotion, each 8oz. For the price, you really can’t beat it. Banana Boat is a staple sunscreen especially for my nieces and nephews who can go through a bottle of sunscreen in just a couple weeks. I like the lotion for base layer, and spray for reapplication when they don’t want to sit still, haha. The sport formula is great, it blends and goes on without much hassle. Definitely sweat resident too!

Excellent Coverage and Very Easy to Apply
Size: 6 Ounce (Pack of 2), Style: SPF 50, Size: 6 Ounce (Pack of 2), Style: SPF 50
I bought this Banana Boat Sport SPF 50 spray about six months ago, and it has worked perfectly for all my outdoor activities. It provides strong and reliable sun protection, even on very sunny days, and I really appreciate that it protects from up to 98% of burning rays. I’ve used it at the beach, walking outdoors, and even on long days outside, and I haven’t experienced any sunburn. The spray format makes it very easy to apply—quick, even, and mess-free. It absorbs fast without feeling sticky or heavy on the skin, which is something I love because I don’t like sunscreens that leave a greasy layer. It’s also water-resistant, so it stays on even when I sweat or go into the water. Overall, this sunscreen is ideal if you want strong protection, easy application, and a formula that feels comfortable on the skin. I would definitely buy it again and recommend it for anyone who spends a lot of time outdoors.

29 years of riding a Harley, THIS is the best sun protection I have found for long SUNNY day rides!
Size: 6 Ounce (Pack of 2), Style: SPF 50, Size: 6 Ounce (Pack of 2), Style: SPF 50
This is my "Go To" Sunscreen of choice that I find is the best to quickly spray my arms down good before a long Harley Motorcycle ride! I have tried many brands and styles from creams to face specific to lip balm but this one can does it all in my case! I quickly spray my arms ( no rubbing in required ) and a quick spray in my hand and I then rub my nose and ears , face and i'm ready to ride and I am protected! Most times I only apply this product once a day and works better than anything else for my needs. I am light skin but I have ridden lots this Summer and my arms never burn and now have a deep tan as we are entering fall... I made the mistake of trying a store brand that looked like this product but was oily and never used it but once! This Banana boat once sprayed on my arms, I never think about it again as its gone but still protecting my skin! This is the best I have found after 29 years or riding a motorcycle to protect my skin with the least amount of trouble , No strange or tropical smell, NO greasy feel just quick applied lasting sun protection that has proven itself mile after mile! The BEST Sun product I have found!
