Grape Seed Extract
Grape Seed Extract
Grape Seed Extract is rich in antioxidants and proanthocyanidins which support the normal inflammatory response and are powerful free radical scavengers.
Grape Seed Extract
Lutein is a rich source of carotenoid antioxidants necessary for protection against free radical damage in the retina and lens.
Omega-3 Fatty Acids
Omega-3 Fatty Acids
Omeg-3 fatty acids contain essential fatty acids EPA and DHA that cannot be made by the body and support retinal health.
Omega-3 Fatty Acids
Vitamin C
Vitamin C
Vitamin C, also known as ascorbic acid, is a potent water-soluble antioxidant that is necessary for the growth, development, and repair of all body tissues. Vitamin C is vital to your body's healing process.
Vitamin C
Green Tea Leaf Extract
Green Tea Leaf Extract
Like green tea, green tea leaf extract is a great source of antioxidants, credited with a wide range of health benefits. The antioxidants in green tea leaf extract help to support heart, liver, and brain health, as well as supporting healthy skin and overall immune system wellness.
Green Tea Leaf Extract
Vitamin E
Vitamin E
Vitamin E is found naturally in some foods, added to others, and available as a dietary supplement. Vitamin E is the collective name for a group of fat-soluble compounds that provide antioxidant support.
Vitamin E
Alpha Lipoic Acid
Alpha Lipoic Acid
Alpha Lipoic Acid, or ALA, is an occurring antioxidant that's made in the body. Alpha Lipoic Acid is a universal antioxidant that is important for normal liver function and vision.
Alpha Lipoic Acid
Aids in blood circulation and helps your body produce collagen. Rutin enhances vitamin C activity to scavenge free radicals but can also possess some of this activity on its own.
Astaxanthin helps to filter harmful blue light from the eyes and improve blood flow.

  • Our powder form is easier to mix versus regular Ocu-GLO® Gel-Caps - just open the capsule and sprinkle!
  • Easier administration at mealtime for medium and large dogs
  • Formulated by board certified veterinary ophthalmologists
  • Includes GLO® for optimal vision health: Grape seed extract, Lutein and Omega-3 fatty acids
  • Specifically formulated to support canine eyes
  • Optimal for pets with sensitive GL tracts
  • Astaxanthin for enhanced antioxidant support
  • Safe for perioperative use in dogs

Ocu-GLO® also:

  • Contains 3Xs the Lutein/antioxidant potency of the other internet supplement brands
  • Has no synthetic colors
  • Has no harmful or unwanted preservatives
  • Is made in the USA from US and globally sourced ingredients

Some of our canine friends have always been extremely hard to pill. With Ocu-GLO® PB XL, it's very easy to give them the supplement they need! Simply crack open the capsule and sprinkle the powder. Our new formula is great tasting and will go down easily the first time.

Store this product in a cool, dry place (59 - 86 degrees Fahrenheit / 15 - 30 degrees Celsius).
Ocu-GLO® is formulated with different antioxidants that work to support eye health through the quenching of reactive oxygen species (ROS). These active ingredients include:
  • GLO® Proprietary Blend
    • Grape seed extract: Grape seed extract contains different proanthocyanidins such as: catechin, epicatechin and gallic acid, which work to inhibit key components of reactive oxygen species production and stress induced cell signaling in the canine lens epithelium.1
    • Lutein: Lutein is a carotenoid that has a large body of evidence that supports its antioxidant activity in the eye. Lutein deficiency has been associated with an increased risk of age-related macular degeneration.2 Lutein supplementation also increases lymphocyte proliferative response and the expression of major hiscompatability complex II (MHC II).3
    • Omega-3 fatty acids: Omega-3 fatty acids, in the form of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), regulate the inflammatory response, vascular death and regeneration, and photoreceptor apoptosis (cell death) in the eye. A decrease in DHA has been associated with an increase in cytokine-induced proinflammatory signaling in the retina. An increase in both EPA and DHA have been shown to reduce blood vessel damage and hypoxic injury after a retinal insult, as well as reduce photoreceptor apoptosis.4
  • Vitamin C: Vitamin C, in the form of ascorbic acid, is a water soluble vitamin and antioxidant that is vital to the healing process. It is required for neutrophil apoptosis and clearance, and contributes towards collagen synthesis, maturation, secretion, and degradation.5
  • Green tea leaf extract: Green tea leaf extract is a great source of antioxidants that have been credited with a range of health benefits. Green tea leaf extract contains catechins that have been shown to regulate the inflammatory response in the eye from infectious, non infectious, and oxidative complications.6
  • Vitamin E: Vitamin E refers to a group of fat-soluble compounds. Supplementation of one of these compounds, α-tocopherol, attacks free radicals to prevent lipid oxidation in retina and other body tissues.7,8
  • Alpha Lipoic Acid: Alpha Lipoic Acid, or ALA, is an essential cofactor for the synthesis of glutathione, the body’s most potent endogenous antioxidant. ALA and glutathione both work to scavenge free radicals to protect the lens from oxidative stress.9
  • Coenzyme Q10: Coenzyme Q10, or CoQ-10, is a naturally occurring quinone found in most organisms. CoQ-10 is essential for the health of virtually all tissues since it is involved with the production of adenosine triphosphate (ATP). Decreases in CoQ-10 have been linked to the development diseases that result in an increase in reactive oxygen species (ROS), as its antioxidant activity helps prevent modifications of proteins and DNA by ROS.10
  • Zinc: Zinc is a mineral that has potent antioxidant activity. Zinc can help protect membranes from iron-initiated lipid oxidation while working synergistically with other antioxidants.11
  • Vitamin B1 (Thiamin HCl): Vitamin B1 is important for neuromuscular development and aids in cellular metabolism.
  • Vitamin B3 (Niacin): Vitamin B3 may help lower serum triglyceride, cholesterol, low density lipoprotein, and very low density lipoprotein levels in the blood.
  • Vitamin B5 (d-calcium Pantothenate): Vitamin B5 is essential for the breakdown of fatty acids, amino acids, steroids, and cholesterol. Vitamin B5 also functions as an antioxidant.
  • Vitamin B6 (Pyridoxine HCl): Vitamin B6 helps with hemoglobin formation as well as the metabolism of fats, carbohydrates, and proteins.
  • Vitamin B7 (Biotin): Biotin is an enzyme cofactor involved in the metabolism of amino acids and the biosynthesis of fats and carbohydrates.
  • Vitamin B9 (Folic Acid): Vitamin B9 is important for cell growth and development.
  • Vitamin B12 (Cyanocobalamin): Vitamin B12 is an enzyme cofactor that is essential for cell growth and red blood cell development.
