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.

Dog approved for fun, human approved for durability for the price.
Size: 8 Inch Diameter, Color: Orange
This has been my dogs favorite outdoor toy for years . I love these because they are durable and won't deflate when bitten or when carried around in their mouth.... no matter how many holes the dogs put in them. We leave these outside year round even in Minnesota winters. It is strong enough to hold up yet soft enough to be safe on their teeth. Now I do want to say although it is really durable it is not indescribable. IF you have a heavy chewer or a dog that loves to destroy toys, they would need supervision with this I think. My dogs don't try to chew this up but they do wear out over time. We replace it every 2 to 3 years on average. Definitely dog approved and recommended in my home, and human approved for cost and durability. I hope your dogs love it as much as mine do.

Best ball for dogs!
Size: 8 Inch Diameter, Color: Red
This is the best quality and long lasting ball for dogs. It's soft enough to kick and durable enough to where they can chew and chew and it will not lose It's shape. We play hardcore everyday for months and it holds up. Never have to worry about chunks falling off and peeling. Border Collie approved!! Also, $8 cheaper off amazon VS pet store or pet store website. You'll know when it has to be replaced once you have to manually re-inflate with your hands but thats after many many months.

GOOD BALL
Size: 6 Inch Diameter, Color: Apple Green
This is my second time buying this ball for my blue heeler, and it is easily his favorite toy. It is very sturdy, especially for hard-playing dogs, and handles rough outdoor play sessions effortlessly. The design is brilliant because it does not go flat, yet my dog is still able to bite it and get a good grip on it. It’s the perfect combination of being tough but still flexible enough for a dog to enjoy carrying around. For comparison, our first ball finally stayed flat after a solid 2 months of non-stop, hardcore playing, which is a massive win compared to other toys he destroys in minutes. If you have an active, high-energy dog that loves to play rough, this ball is highly recommended!

Best Ball ever! Aussie is obsessed
Size: 6 Inch Diameter, Color: Orange
I will never buy any other ball!!!! I bought the 8 inch which my crazy Aussie liked. The 6 inch one he won't stop carrying it around. his face use to be so sad when he would pop other balls. This one deflates and fills back up instantly! He chases it and chews on it. We gone through a lot of balls, but this is going to be a staple in our house!

Great for crazy pups!
Size: 8 Inch Diameter, Color: Ocean Blue
Tough and fun! This is a great toy to keep in the yard for play. I have a heavy chewer. He can get a hold of it and carry it around but it doesn't pop. It is soft enough but also strong. My dog loves to herd it around. He loves it!
