    Rated 5 out of 5 by from Good Results! My 36" tall miniature horse Nozzy has been on this product for a little over two months. He will be 7 years old this year. He's been tested for IR and Cushings with negative results, but he has the build of a metabolic horse. He loves to eat and it's been hard keeping him at a good weight. He has never foundered. I thought I would try SmartMetabo-Lean to see if it would help Nozz. It has! He has lost about 40 pounds at this point, which is good for a short amount of time.He LOVES the taste of this product and gobbles it up. I hope to be able to give another review after the next few months. The photograph is Nozzy at the start of his reducing plan and his SmartMetabo-lean.

    Rated 4 out of 5 by from Made a difference I have been using this for two months. I bought it for my draft cross and shetland pony. It has helped them maintain their sugar balance over the winter. I will continue to track their health on this supplement. Gave it 4 stars because it has only been 2 months.

    Rated 1 out of 5 by from 2 horses on it, no weight loss I had 2 horses on this Metabolean for over 6+ months; neither of which lost weight (no other variables). Also, palatability is an issue - horse not eating all of the pellets (not a picky eater). So, I am going to switch to a different product. Also, shame on Smartpak for trying to get people to review this product within the first two weeks of purchase, when weight loss results cannot be verified due to product. I suspect that is why this product has such a good rating. Notice which reviewers rated the product with 4-5 stars within the first few days/weeks of purchase instead of testing for 1-2 months minimum.

    Rated 4 out of 5 by from Pony looks amazing! My daughters 14 year old pony was diagnosed with Cushings. Started her on Metabo-Lean Pellets two months ago and the difference is quite noticeable already! The crest on her neck has decreased, she's lost weight, hair growth has slowed, and her mood has improved greatly! Definitely worth a try!

    Rated 4 out of 5 by from SmartMetabo-Lean/SmartVite Thrive Senior Have had my 20 yr. old draft mare on these 2 products for a little over 2 months now. Her eyes are brighter, ears are perked up more and not such a " deadhead " now. Fat pads over her rib cage area has gone down some. Coat and hooves look much healthier. Can't wait to see how she'll look this summer without all the winter hair !

    Rated 4 out of 5 by from Smart metabo-lean pellets I bought this product because my mare is a eating machine and has gotten quite obese. She only gets low sugar hay. She has been on it for almost a month and I think the fat pad on her utter is getting smaller. She seems a little more content. It is difficult to evaluate this product. She eats it without any problem.

    Rated 5 out of 5 by from LOVE these! Perfect for the too-easy keeper!! After just over a month, my pony (who tends to be quite round, even at age 5) already looks more trim. She loves them and considers them a treat (they smell SO good, I'm tempted to try them myself). These pellets are wonderful!

    Rated 5 out of 5 by from Metabo Lean supplement I bought this for my ten year old gelding, who is insulin resistent. In the short time he has been on it, he seems to have lost the pronounced cresting down his neck. Along with exercise and food reduction, he's losing weight and appears to be feeling great..

    Rated 5 out of 5 by from exceeded our expectations My husband has a 21 year old Paso Fino mare who foundered four years ago. La Pandora (Panda) had never returned to complete soundness, despite corrective shoeing, diet and various supplements. Even our vet had no suggestions. Panda would have periodic "flare ups" when her feet would become extremely sore again. This past July, Panda experienced an especially harsh flare up. We could see that even taking one step was causing her a great deal of pain. She mostly just stood in the paddock. It was so difficult for us to see her suffering this way and my husband talked about having her put down. I knew of SmartPak's reputation and of the science and guarantees behind your products. So I started searching your supplement lists and found a product called SmartMetabo-Lean for horses with insulin resistance. Panda certainly fit the profile for this type horse. I ordered this and your salesperson, Chloe, suggested we add SmartVite Thrive Senior, which I did. This was literally Panda's last chance.. I had high hopes but have to admit, some skepticism. Within a very short time of Panda being on SmartMetabo-Lean, we started noticing improvement. She became less and less sore. Walking became much easier. After just a few weeks, we put one of your grazing halters on her and turned her out in the pasture with the other horses. She has been on the supplement two months now, and has lost a lot of weight, her crested neck has decreased significantly, and she is moving better than she has in years! She actually leads the other horses up to the barn each afternoon for feeding! My husband and I are absolutely amazed at this transformation we witnessed firsthand. Thank you SmartPak for this great, effective product. Panda is now a happier, healthier horse and she thanks you too!Sincerely,Lynda Allen( can send photo if you wish)

    Rated 5 out of 5 by from Smart Metabolean does what it says On my vet's advice began feeding about 3 months ago to my 19 y/o Arab gelding. The fatty pads on his shoulders and by his dock have disappeared and he can graze again (with close monitoring). Thank you for a great product. And it snells good!

    Rated 5 out of 5 by from Works great for my horse! My IR horse has been on this for about 5 months now and he looks great. He's lost more than 50% of his crest and over half of the fatty deposits on either side of his spine - the other fatty deposits (hind quarters, shoulders) have diminished significantly. Thanks SmartPak!

    Rated 5 out of 5 by from Long Term User I have a 19 year old gelding who has always been as easy keeper. Even with being worked continuously and a monitored diet he would never maintain a proper weight. After using this product for a few months we could see a definitive difference in his body composition.He has now been using this supplement for over a year and, keeping along with diet & normal exercise, is maintaining a well-balanced weight.

The only issue has been taste. If doctored up with a little apple sauce(no sugar) and a grated carrot he will eat it now. I plan to continue to use this supplement.
