What is Ocu-GLO®?
Ocu-GLO® is a canine and feline vision supplement that contains a unique blend of antioxidants, vitamins, and minerals that work together to support ocular health and protect against free radical damage.
What are the key ingredients in Ocu-GLO®?
Ocu-GLO® contains key ingredients such as Grape Seed Extract, Lutein, and Omega-3 Fatty Acids which help protect the retina from harmful UV rays and other environmental toxins. Ocu-GLO® helps neutralize free radicals and reduce oxidative stress to promote healthy vision and support ocular health.
How do I give Ocu-GLO® to my pet?
Ocu-GLO® Vision Supplement is available in three unique formulations to meet the specific needs of dogs and cats. This includes our original Gelcaps, our convenient Powder Blend Capsules which can be opened and sprinkled for easy administration, and our most tasty formulation - Ocu-GLO® Chewables! Refer to label instructions for the proper dosage based on your pet's weight.
To ease the administration of Ocu-GLO®, you can wrap the gelcap (or capsule if opening and sprinkling is not preferred) in a small piece of meat, cover it with peanut butter, as long as your animal is not allergic or sensitive, or hide it in something your pet enjoys.
How long does it take to see results with Ocu-GLO®?
The amount of time it takes to see results can vary depending on the individual pet and their specific eye health issues. Some pet owners may notice improvements within a few weeks, while others may take longer. It is important to note that no further change in vision, i.e. maintaining stable vision, is also a positive result of Ocu-GLO®. Continue administering Ocu-GLO® as directed and consult with your vet if you have any concerns.
Is Ocu-GLO® safe for pets of all ages and breeds?
Ocu-GLO® is safe for cats over 1 year of age that do not have a history of liver disease and all dogs over 6 months of age. Ocu-GLO® is formulated by Veterinary Ophthalmologists and has been thoroughly tested for safety and quality.
Can I trust Ocu-GLO® for my dog?
Two very important reasons that you can trust Ocu-GLO®:
- Two Board-Certified Veterinary Ophthalmologists and a Compounding Pharmacist, with over 75 years combined experience in veterinary health, designed Ocu-GLO® and tested its safety and palatability.
- The antioxidant ingredients in Ocu-GLO® are all pharmaceutical grade, which means that they are made under strict Good Manufacturing Practices (GMP) guidelines. GMP standards are much higher than those which nutritional product manufacturers are required to meet. The ingredients are of the highest quality.
I have read that grapes are toxic to dogs, why is Ocu-GLO® safe?
This is a common question and there are some articles in the literature about this topic. There are two components to grapes that have nutritional benefits. The seeds of grapes are completely safe for all species evaluated so far, including dogs. The seeds of grapes contain proanthocyanidins, a group of antioxidants that benefit eyes and the rest of the body. There have been no side effects to grapeseeds known as of yet. However, there are compounds in the skins of grapes and raisins, especially darker varieties of the fruits, that cause kidney damage in dogs.
Why was titanium dioxide removed from the inactive ingredients and replaced with red and black iron oxide?
You may have noticed a recent adjustment to the inactive ingredients of our Ocu-GLO gel cap formula. Recently, the titanium dioxide was removed from our formula and replaced with red and black iron oxides. These ingredients are used for coloring purposes only. It gives the gel cap itself its color. Our team of advisors are constantly evaluating the best available options for our formulary and in general, we have found this to be a more "comfortable" fit for our pets!
What is the shelf life of Ocu-GLO®?
The shelf life is three years due to the special way in whichOcu-GLO®is manufactured. Because oxygen can oxidize and break down antioxidants, oxygen is intentionally removed from the inside of the Gelcap during the manufacturing process via a nitrogen gas exchange process.
What sizes does Ocu-GLO® come in? What is the suggested serving, and do the Gelcaps need to be given with food?
Ocu-GLO® comes in 90 count bottles in two convenient sizes:
1. One for Small Dogs weighing 10 lbs or less. They are given 1 Gelcap daily.
2. One for Medium to Large Dogs weighing 11 lbs or more. Dogs between 11 and 30 lbs receive 1 Gelcap daily; 31 to 60 lbs receive 2 Gelcaps daily; 61 lbs and over receive 3 Gelcaps daily. Giant breed dogs over 100 lbs can receive 3 or 4 Gelcaps daily.
Two Small Dog Size Gelcaps equals ONE Medium/Large Dog Size Gelcap.
If the daily dose is more than one Gelcap, it can be given all at once or divided throughout the day. It should be given with a snack or a meal to improve absorption, and, may make it easier to give Ocu-GLO® to your dog.

How big are the Ocu-GLO® gelcaps?
The Ocu-GLO® gelcaps in the Medium/Large Dog size are 2cm long and 0.5cm wide. The Small Dog size gelcaps are approximately half that size.
What is the meaning of the percentages after the individual ingredients listed (like on the Ocu-GLO® label)? Specifically Lutein Extract 20% and Omega-3 EPA/DHA 55%?
The percentages listed refer to the percentage of active ingredient in each powder that we use, not the percentage of that ingredient in the proprietary blend. For example: when you buy Grape Seed Extract it contains 95% active ingredient and 5% inert or inactive ingredient. That means that for every 1000mg of the extract that we use we only get 950mg of the active ingredient. Therefore, if we want to get 25mg of the active ingredient in Grape Seed we will need to add 27.4mg of the extract.
This conversion becomes much more important when we are referring to Lutein 20% or the Omega blend which contains only 55% EPA/DHA. One gram (1000mg) of our 20% Lutein contains 200mg of actual Lutein, the rest is inert ingredients from the plant, so we must include 5 times the amount of the actual active ingredient that we want to include. The Omega blend contains 55% EPA and DHA, so 1000mg of that blend only contains 550mg of actual EPA and DHA. These conversions have have been carefully considered and calculated so that our product contains 100% of what we say it does. Some manufacturers do not do this and may give you 25mg of the Extract, which in the case of Lutein would only provide 5mg of actual Lutein. Some manufacturers do not do this and may give you 25mg of the Extract, which in the case of Lutein would only provide 5mg of actual Lutein.
Do I need to stop Ocu-GLO® before during or after surgery for any reason?
Many veterinary ophthalmologists advise clients to administer Ocu-GLO® up until the evening prior to surgery, and then no food, supplement, or oral medications the morning of surgery.
Ocu-GLO® is to be restarted with dinner the evening of surgery if the patient is eating well -- either at home or if the patient is in the clinic. We always recommend that the owner check with their veterinarian before administering any supplement prior to surgery.
What if I notice a discoloration in my pet's stool after giving them Ocu-GLO®?
Fecal coloration change with Ocu-GLO®, which can be normal. Usually you will see more of a hint of yellow/orange because of the strong lutein ingredient that comes from the yellow marigold plant.
We are always concerned because dark, tarry stool can mean digested blood (which is not good). If noticed, we usually ask clients to stop Ocu-GLO® for 3 days and see if there is a change back to normal stool. If so, then we suggest starting back on Ocu-GLO® at 1/2 the dose.
For example, if this animal is on one Ocu-GLO® a day, then we would give one Ocu-GLO® every other day, as many animals can have sensitive gastrointestinal tracts. Also, any medications that animals are on while on Ocu-GLO® is very important to know, as the medication alone can cause indigestion which can change stool color (for example, pentoxifylline).
Is it necessary to give a multi-vitamin with Ocu-GLO®?
Most multi-vitamins available for dogs have very low amounts of vitamins and minerals and are primarily to complement the diet that they are eating. The better quality foods are supplemented with a variety of antioxidants and vitamins/minerals but if they are cooked at too high a temperature, many of those nutrients may be somewhat depleted. Therefore, supplementing is a good idea.
We put the equivalent of a multivitamin into Ocu-GLO® so that owners would not have to give a separate multivitamin. However, if you choose to give a separate multi-vitamin, it is unlikely that you will overdose your dog. The bottom line is that if you only want to use one product, use Ocu-GLO®; but, if you like the multi-vitamin that you use, we are happy to advise you on whether it is too much or just right.
Are the Soybean oil and Soy lecithin ingredients found in Ocu-GLO® NON-GMO?
Yes. Both Soybean oil and Soy lecithin raw material used inOcu-GLO®for Small and Medium/Large Dog Products are NON-GMO.
Is there Caffeine found in Ocu-GLO®?
Yes. Green tea extract raw material present inOcu-GLO®contains approximately 0.3 to 0.4 % caffeine. There is 40 mg raw material per softgel inOcu-GLO®which is equivalent to 0.12-0.16 mg caffeine per softgel. This is the trace amount of caffeine present in one softgel.
Are there animal products in Ocu-GLO®?
Yes, the outer gelatin coating has beef made from bones and the omega fatty acids are from sardines and anchovies.
If beef is a potential allergen in your dog, you can use the snip caps and open the capsules to let your dog eat the contents where the important active ingredients are.
What is the Calorie, Fat, Protein and Carbohydrate content is in a single dose in Ocu-GLO®?
In Ocu-GLO® Medium/Large each softgel contains 4.02 calories. This is derived by combining together 300mg of Fat (2.7 calories), 220mg of Protein (0.88 calories) and 110mg of Carbohydrates (0.44 calories).
In Ocu-GLO® Small each softgel contains 2.07 calories. This is derived by combining together 150mg of Fat (1.35 calories), 120mg of Protein (0.48 calories) and 60mg of Carbohydrates (0.24 calories).
My dog is already on an omega-3 fatty acid supplement. If I give Ocu-GLO® will this be too much in omega 3 fatty acid concentration?
Ocu-GLO® has an appropriate amount of Omega 3 fatty acids for the weight of your dog, however, some dogs (and humans) can tolerate higher doses if they need to take more for other diseases such as skin problems.
We recommend stopping the extra Omega 3 fatty acids while you begin Ocu-GLO®, then after a week, you can gradually add in the other Omega product. If your dog develops diarrhea, then the amount of omegas is too high and do not use the extra dose.
Is there Zeaxanthin in Ocu-GLO®?
Zeaxanthin is a component of the Lutein in Ocu-GLO® and therefore is a part of the Ocu-GLO® Formula. The gelcaps include Zeaxanthin in the following amounts:
LARGE DOGS SOFTGELS Zeaxanthin is 3.3 mg (in Lutein) per softgel.
SMALL DOGS SOFTGELS Zeaxanthin is 1.725 mg (in Lutein) per softgel.
Are there any carbohydrates or sugars in Ocu-GLO®?
Glycerin in the shell ofOcu-GLO®is a source for carbohydrates but the amount is not high (due to softgel size). No other RM in the product is carbohydrates or sugars. Gelatin is a source for protein and not for carbohydrates or sugars.
What is the source of the imitation chicken flavor in Ocu-GLO® Chewables?
The imitation chicken flavoring comes from yeast.
What is Ocu-GLO® by Angel Eyes?
This was a product which was discontinued in 2020. Any product that remains may no longer be within expiration and should not be purchased or used.
Do you offer an Auto-Ship Service?
Yes! We offer Auto-Ship Service for all of your pet's vitamin needs. Simply check the Auto-Ship boxes on checkout and select your weekly timeline.
Why are our products sometimes unavailable?
Animal Necessity’s products are made in small batches on purpose. Here are a couple of reasons why:
Ingredients Matter
Every ingredient used in our products are sourced from other small businesses. Which means we get them fresh, and in smaller quantities than the big guys. It also means the ingredients are of the highest quality because everyone involved knows exactly where they came from.
Freshness
Our products are manufactured more frequently to ensure your pet is taking in these hand selected ingredients at their freshest and most potent point. Small batches ensure that your pet's supplements were made within a couple of months of purchase. Can the big brands claim that?
You Aren't Paying for Waste
When purchasing from larger, mass manufacturers- offering mainstream products, you pay for more than just ingredients. You are also paying for unused, damaged goods, unsold products, unneeded packaging, and multiple shipping expenses. When you buy small-batch products, rest assured most of your dollars are paying for the high-quality ingredients, and not much else.
