Equinety™ Horse XL (powder)

  • Best Trait = Fabulous marketing team (wish they were mine)
  • Worst Trait = Poor dosage considering high cost

Consider this product if…

  1. You believe in the power of placebo effect
  2. You’d like to support the people who work here
  3. Adding powders to your horse’s feed makes you feel good

I don’t need to go farther than the feeding directions to know that I will never recommend this supplement. Let’s think critically about just one amino acid they claim to offer in this product using simple cowgirl math…a recommended scoop is 5 grams > an average 1,100 lb horse in moderate work needs 33 grams of lysine > lysine is only 1 of 8 amino acids added to this supplement > how do you fit 8 amino acids at any meaningful dose in 5 grams?!? They do have a VERY savvy marketing department however, and so they advertise 1250 mg (1 thousandth of a gram, to make it seem like a lot) of L-lysine HCl on their website. That’s 0.1250 grams or 0.37% of the average horse’s lysine requirement. To compare, Uckele Tri Amino offers 29% of requirement and a typical ration balancer offers about 28% of lysine requirement.

How about this angle if you’re still not convinced. My husband adds a hydrolyzed protein powder to his smoothies in the morning. It offers 25 grams of amino acids per 30 gram serving and this is for a 200 lb human instead of a 1,100 lb horse. If you were to scale that, the horse would need 137.50 grams or 28 scoops of Equinety Horse XL per day. I’m sorry, but this just does not make sense.

Fix with forage first.
A higher protein forage will promote the production of non-essential amino acids in the horse’s digestive system.

Company Information & Communication

Rating: 1 out of 5.

I always start my research at the bottom of the feed label or the bottom of a company website. It’s surprising what you will find there- both good and bad! What I learned (and could not learn) about Equinety shocked me! Furthermore, after four months and three emails, they still have not responded to any requests for more information.

Poor communication and company information forces me to give this product one star in this category. Team Equinety makes a disclaimer online and on the packaging that they their statements have not been reviewed by the Federal Drug Administration. Frankly, this is normal for equine supplements and an appropriate statement for them to make, but they would not clarify this product’s safety, efficacy or quality via multiple email requests. I can only assume that Equinety Horse XL product is not certified, regulated or controlled by any third party regulator in the United States including the National Animal Supplement Council (NASC). There is a claim that their product was given a LRVHP Number- the link goes nowhere- but this Low Risk Veterinary Health Product number seems to be a program offered by Canada stating that the product will not do harm.

Finally, I would suggest that the creator of Equinety Horse XL take a basic Equine Nutrition 101 class as he/she claims that their amino acids are absorbed in the horse’s stomach and magically go straight to the pituitary….people….nothing gets absorbed in the horse’s stomach! If the creators of Equinety don’t understand the horse’s digestive system, why are they creating horse products? Just take a closer look at their infographic at https:www.teamequinety.com/how-it-works/ titled “Equinety has no fillers, no sugars, and no starches!”.

They have a very long disclaimer on their website and they do not, under any circumstances, offer refunds. In fact, there is a $25 restocking fee even if the product is unopened.

Feeding Directions

Rating: 0.5 out of 5.

The one-size-fits-all approach to equine supplementation should trigger alarm bells for any equestrian. Equinety Horse XL feeding directions make no adjustments for your horse’s size, age, activity level or forage quality. Perhaps more alarming is that the company states that Equinety Horse XL is the exact formula and dosage as it’s original human product! I would love to hear any evidence that they may have to suggest that a human dose will have the same effect on a different species 5.5 times its size with a very different digestive system.

Ingredients List

Rating: 2 out of 5.

There are eight amino acids offered in this product including lysine, arginine, ornithine, glycine, leucine, isoleucine, valine, glutamine. Do they have important functions in the body- yes. However, only one of these, lysine, is considered an ‘essential’ amino acid. An essential amino acid is a building block of protein that MUST be consumed in the horse’s diet. The other seven amino acids are considered ‘non-essential’, because the horse manufactures them in their bodies.

Team Equinety is very proud of what their product does NOT contain; starches, sugars, fillers, artificial flavors, preservatives, or colors. I’m very glad to hear this considering that they don’t have enough room in their 5 gram serving to supply the nutrients they do want to deliver.

Guaranteed Analysis

Rating: 1 out of 5.

It’s always suspicious to me when a supplement company chooses to use the tiniest unit of weight in its guaranteed analysis. This is especially true for protein supplements designed for horses, because horses need grams of protein, not milligrams (1/1000th of a gram). By guaranteeing 1,250 milligrams, rather than 0.1250 grams they are attempting to make the product look more robust than it is.

A 600 gram tub of Equinety Horse XL is sold on their home website for $99.99 before shipping. At the recommended 5.2 gram scoop per day, that’s $1.00 per day or $365 per year. As I review more and more poor quality supplements, there is a reoccurring pattern that they cost almost exactly $1.00 per day. Is this coincidence? Probably not.

How does that compare to other products on the market? Well, a previous review of Uckele Tri-Amino supplement sells at $0.79 per serving and contains meaningful levels of three essential amino acids. A typical ration balancer will cost you between $0.75 and $0.90 per day. Whey containing protein supplements will cost you between $1.00 to $1.60 per day.

Despite the nearly 44,000 likes on Facebook, I give this supplement two thumbs down. A simple glimpse at the feeding directions should cause suspicion. If you’re not sure what I mean by this, you might consider taking my next equine nutrition webinar series.

I would gladly hear any proof to correct my assumptions above from Team Equinety. This review will be updated at that time.
