Platinum Performance Healthy Weight Supplement

So I am a fairly big fan of Platinum Performance. I use it for my dogs and have used the hoof stuff for my horses in the past with great results. My OTTB has been going through Rehab and we are finally on the other side and back to our normal routine. That being said, during Rehab he gained a lot of weight, good weight, and now that hes back to his normal routine unfortunately hes burning more calories than bringing in. He gets a Fish Oil supplement but we recently found out about the Healthy Weight supplement and I am curious to know if others have used it and their thoughts. I respect that what works for others wont work for me but curious on general reviews.

Here is his current feeding routine

AM:
3lbs of SS Carb Care Performance
1 scoop Fish Oil
1 Scoop 100% Pure Biotin
1/2 scoop of Mg
1 cup of Aloe

PM:
3lbs of SS Carb Care Performance

I have used it. It’s just flax oil. My horse thought it was tasty. I switched to UltraCruz flax oil because it was cheaper. If you are curious about it, Platinum might send you an 8oz sample. They did for me. My horse can be really picky about oils, so I appreciated that before spending money on a big jug.
