Ascorbyl Palmitate (Fat soluble vitamin C): possesses all the benefits of vitamin C, but unlike the water-soluble form, is able to be stored in the lipid cell membrane until the body is ready to put it to use. Furthermore, it has histamine lowering properties and increases lymphocyte formation.

Glucosamine HCl: a natural compound that is found in healthy cartilage. It is used to help form and repair body tissues and as your animal ages, the natural production of glucosamine in the body slows. It has been shown through many studies to alleviate pain and help rebuild cartilage. Research shows that providing supplements of glucosamine can help restore joint function and activity levels.

Chondroitin Sulfate: is a naturally occurring product found in animal cartilage. When chondroitin is added to the diet it helps to reduce the level of destructive enzymes, which accelerates cartilage destruction.

Lithothamnium (Calcified algae): a calcium supplement that absorbs water, and relieves pain.

Active-Aloe 200:1: is the leading aloe vera for purity and biological activity. Our 200:1 extract is produced by refractance window drying the juice from the inner leaf. The result is the highest biological activity of any drying method. All the immunological activity of fresh aloe is concentrated in Active-Aloe.

Bromelain 2400 GDU (Gelatin Digesting Units): is an enzyme with documented anti-inflammatory activity. Our bromelain is 2400 GDU (Gelatin Digesting Units), the highest potency available.

Calcium Fructo-Borate: Plant-based boron supplement
Serrazimes is a fungal enzyme with wide ranging therapeutic benefits. It has been scientifically proven to reduce inflammation and promote joint flexibility.

Vitamin K2 (menaquinone): has a wide variety of benefits for the circulatory system.

Argentinean Beef Liver: is rich in vital nutrients including energy producing B vitamins, extremely low in carbohydrates and serves as an excellent source of protein. It is a flavoring well liked by cats and dogs. Additionally, our “flavoring” has many health benefits. It comes from fresh, hormone-free Argentinean Beef liver carefully processed to preserve all the fragile nutritional elements.

Arabinogalactan (larch tree extract): is a source of dietary fiber. It has potential therapeutic benefits as an immune stimulating agent. Arabinogalactan is a pre-biotic, actively fermented by intestinal microflora and is effective at increasing beneficial anaerobes such as those in Pet Flora.

Success Stories

The statements on the Testimonial pages are those of the Vitality Science Costumers only. Any statements and opinions included in these pages are not those of Vitality Science.

” I also ordered the Combo Canine Flex Lipids for our 8ish year old pound scrounge named Tater Tot who tore his ACL on both his back legs. He was on another brand of glucosamine/conjointin pill and was doing OK but not great on it. Tater Tot has also shown much improvement on the Combo Canine Flex Lipids program. He still is sore sometimes when he runs and plays too much but he’s much brighter and his back legs definitely seem to bother him less. Those torn ACL’s are a bugger. The only other option for him was surgery which I wasn’t too keen on because of the cost and who knows how he’ll do even if he did have the surgery. Thank you, Vitality Science for great products and great customer service. It’s nice to call and actually get a human who knows the products and can answer all your questions. I’ve already recommended VS to my dad.”
