Alpha Lipoic (ALA) is a thioctic acid that is produced by the body. It plays an essential role as an antioxidant, protecting cells from damage, and specifically supports healthy vision and optimal liver function.

Special Note: We recommend consulting with your veterinarian or our veterinary support team before using this supplement with cats or if your animal has any ongoing medical concerns or known allergies to pollen, grass or plants.

For cats, we would recommend Ocu-GLO Powder Blend because of the lower, cat-appropriate dosing.

Alpha Lipoic Acid (ALA) is a water and fat-soluble endogenous thioctic acid that acts as an antioxidant and cofactor for cellular mitochondrial metabolism. ALA is reported to neutralize free radicals, dissolve toxic substances in the liver1, recycle vitamin C (ascorbic acid), and increase the body’s production of glutathione.2 Glutathione is the body’s most potent endogenous universal antioxidant. An imbalanced cellular glutathione redox cycle contributes to the formation of cataracts, and ALA recycles glutathione to protect the lens from oxidative stress causing cataracts.3 This universal antioxidant promotes normal insulin sensitivity and glucose metabolism, though actual levels of insulin and glucose may not change.4

ALA as a natural supplement is rapidly absorbed from the gastrointestinal tract. If patients have concurrent medical conditions, including insulin resistance, please contact our veterinary support team for recommendations.

Special note: This supplement provides a dose of ALA that is, on average depending on weight, 4.5 times less than the toxic dose established for cats.5 For cats, do not exceed doses greater than 13 mg/kg daily, and for dogs, do not exceed doses greater than 400 mg/kg daily.
