Equine Omega Complete by O3 Animal Health

*Updated June 2021.

  • Best Trait = fish oil is an ingredient
  • Worst Trait = misleading marketing and no guarantee for ALA, EPA or DHA even though those are the nutrients we’d feed this for!

Consider this product if…

  1. You are trying to put weight on a horse and want an oil to top dress
  2. You find it on clearance or your horse neighbor gives you a free bottle
  3. …struggling to think of a third reason…

Why Review this Product?

I have a theory and it goes like this…the products with the most amount of social media marketing are the ones that make the least sense to feed. This product had 94 shares on its last Facebook ad, 130 comments and 752 likes. I had to review it and test my theory!

The Actual Review in 5 Parts

Company Information & Communication

Rating: 1 out of 5.

This product makes a LOT of promises- none fewer than 12 listed on their website. Claims for this one product, based on soybean and fish oil (we don’t know how much of either), include inflammation reduction anywhere in the body, reduced chances of colic, improved hoof growth, improved hair coat, improved immune health, improved digestive health, maintains (not sure what that means) blood flow during work, improved reproductive health, aids in cell development and function (WOW), reduces stress and anxiety and equine depression…oh and “delays” lactic acid accumulation. Where do I sign up, right!!!

Come on…!!!…am I the only one who cringes when a supplement company makes a claims list that long? Overall, I found their online marketing material misguided and hokey. They make fact finding very difficult if not impossible. I had to go to other websites to find more detail (such as the publicly available patent from Google Patent search), and what I found on those OTHER websites was NOT good.

*Research on this product presented at the 2021 Equine Science Society Conference validated my rating. This product showed little significant effect on in vitro (tested in a tube) intercarpal cartilage explants when tested by the University of Goelph in Canada. However, the creator of this supplement referenced this study as conclusive evidence for use of this product in correspondence.

Garland, A., C. Wierenga, and W. Pearson. 2021. 60  Chondroprotective effect of an omega-3 fat supplement in a cartilage explant model of inflammation. Journal of Equine Veterinary Science (100): ISSN 0737-0806. https://doi.org/10.1016/j.jevs.2021.103523.

Feeding Directions

Rating: 4 out of 5.

I finally found the feeding directions on their FAQ page, which indicates 1 ounce serving for every 300 lbs of horse. I like that they help owners decipher amount by giving them a sliding scale by weight. They also distinguish between horse at high performance and the maintenance dose which I appreciate. Feeding directions indicate four ounces per day for an average 1,100 lb horse in moderate work. Double that dose for the first 10 days and feed upwards of 8 ounces per day when in high stress situations.

Ingredients List

Rating: 1 out of 5.

Why a company would create an omega-3 supplement based on soybean oil is beyond me! They do address the use of soybean oil on their website, but their argument compares cold expeller pressed versus heat processed oils and nothing about how low the omega-3 to omega-6 ratio is in soybean oil compared to other oils (i.e. flaxseed). If not for it’s omega-3 content, why would they base their product on soybean oil you ask? The answer is likely cost and only cost. Soybean oil is one of the cheapest oil products out there- I don’t care that it’s cold pressed or not. I would not recommend this product based solely on its ingredients list.

I’ve never seen an ingredients list like Equine Omega Complete’s. It reads like a piece of marketing on their website. I’d be very surprised if they are regulated by any third party entity with an ingredients list like that!

Guaranteed Analysis

Rating: 1 out of 5.

It was very difficult to find feed label information on their website, but I finally found this gem while searching for it and understood why the feed label was so hard to find.

“Equine Omega Complete has approximately 50% more Omega 3 than fish oil alone. Equine Omega Complete has all three chains of Omega 3, where fish oil has only two.” Accessed on March 10, 2021 at https://o3animalhealth.com/faq/

This is a bold claim meant to distract you from the fact that they do not put omega-3 fatty acid guarantees on their website OR even on the feed label!!!!!!! An omega-3 supplement without guarantees for fatty acids…how are they getting away with this!?!?!?!!?!?

There is a 1,200 IU/dose Vitamin E promise in the paragraph explaining their product, but I wasn’t sure what a dose was until I found it on the FAQ page. Considering that you have to feed four ounces per standard horse to get 1,2000 IU of vitamin E tells me that I need to go elsewhere for the recommended 5,000 IUs of additional Vitamin E recommended for performance horses.

Once again this company’s marketing strategy is distraction. In their guaranteed analysis on the feed label they guarantee minerals. That’s it. Does one buy this product as a mineral source? Absolutely NOT! So why guarantee minerals in an oil based product? To distract you from the poor formulation.

I chose the higher volume 2 gallon option when purchasing this product online in order to save a little bit of money. That means there are 256 ounces in 2 gallons which is 64- 4oz servings or 2 months worth. At $143.90 (free ground shipping) for 2 gallons, that means a daily dose will cost you $2.25 per day. Ugh, this is strike three for this product. No way. I’m not paying over $2 per day for a DHA/EPA supplement that won’t guarantee their only valuable nutrient.

I’m glad that I chose to review this product. I recommend omega-3 supplements a lot, but now I know to stay away from Equine Omega Complete and WHY! If you’d like to see reviews of other omega-3 supplements with fatty acid guarantees and peer-reviewed research support, please find the KER OE3, Stride Animal Health Fish Oil Factor, or HorseGuard Flaxen Flow.
