What people are saying
We started our girl Lady out on E4L and absolutely loved the results! It really complements her current diet. Loved that the ingredients were clinically backed and devoted to gut biome and immune support. Bravo!
Nutrition is the utmost important for our two bulldogs Henry & Beatrice. E4L has been an amazing addition to our dog’s diet. Love the Omega-3s which are very important to us and that it has Pre AND Probiotics for their belly health. Having Senior bulldogs I look for products that have no synthetics and love that E4L is human grade!
My dog enjoys the flavor of this supplement, it wasn’t hard to get him to eat it! I noticed an increase in energy levels. I also used this supplement during the time my dog was healing from a broken leg; I believe it sped up the healing process and decreased inflammation.
Great product! I had never used a supplement for my dog before and I was quite pleased with how much more energy and endurance my dog has. She has enjoyed the flavor of E4L and never turned it down when first introduced. Great for closing the gap of nutrition our dog needs for maintaining a healthy and active lifestyle. Looking forward to the long term health benefits it will provide to keep our dog healthy!
This product is AMAZING!! Prior to finding E4L, I was giving my puppy two different types of powders for her daily nutrition but E4L offered even more nutrients in just one powder. Highly recommend this product for all dogs! Her stools have become so much more firm since starting E4L. Not to mention how shiny her coat is! Everywhere we go, people mention how shiny her coat is. This is definitely a product that we will keep her own FOR LIFE!
Our Mochi has always had a bit of sensitive stomach and stools on the softer side. Adding E4L to Mochi’s meals has not only made her movements more regular, but also helped improve her coat and overall health. Would absolutely recommend E4L for other bulldog owners
Absolutely love this product. Not only did my doggo love the taste but lost weight and had more energy then normal. She was happy and full of playtime. Her stool also appeared more healthy.
As someone who works in the veterinary field I’m always looking for the best nutrition supplements for my dogs. E4L provides the added nutrition I’ve been looking for to ensure our dogs are at their healthiest. Our Golden Retriever can be picky but he loves E4L and would finish his bowl every time. Definitely something we will keep using!

Research-backed ingredients drive our process and product.
Clinical research is at the heart of our mission to move dog nutrition away from dangerous pseudoscience. Far too many canine-based nutrition brands make label claims but provide zero evidence. Our Proven First mission focuses on clinical-based trials to prove ingredient effectiveness.
