Questions & Answers

3 Customer Questions


2 questions.. What is NSC%? How is this different from the MicroMax supplement from KER?

Answer by ChewyAug 12, 2021
The NSC in the All-Phase horse supplement is approximately 20%. The biggest differences between All-Phase Low-Starch Ration Balancer Pellet Horse Supplement and the Micro-Max Micronutrient Hay Flavor Pellets Horse Supplement are the feeding rates and protein inclusion. All-Phase is a ration balancing feed containing concentrated levels of protein, vitamins, and minerals to meet recommended nutrient requirements for optimal health. The average feeding rate of All-Phase is 1-2 pounds daily. Micro-Max is a supplemental source of highly concentrated vitamins and minerals without added protein. The serving size for Micro-Max is 60-120 g per day depending upon the size of the horse and other dietary components. Both products contain highly digestible forms of nutrients including chelated minerals and natural-source vitamins to fortify and balance a diet.

Does this feed need to be soaked?

Answer by ChewyNov 23, 2025
This feed does not need to be soaked.

How much iron does this contain per pound?

Answer by ChewyJan 29, 2025
All-Phase contains 160 ppm added iron as a bioavailable source of ferrous sulfate. Iron is added in a bioavailable form to ensure sufficient available iron to meet the recommended daily allowance.

All Phase Horse supplement

I have been looking for this feed supplement for a while. I use to top dress my horses oats with this grain years ago. I hope I still get the same results I did

I have been looking for this feed supplement for a while. I use to top dress my horses oats with this grain years ago. I hope I still get the same results I did when I supplemented their feed with All Phase. So far they love the taste and their coat condition seems to be improving.

My Morgan loves it

My horse is on forage so a ration balancer is a must. I am preemptively holding off on sugar of any kind because he is an easy keeper and Morgans are prone to metabolic issues and Cushings. We are off to a good start with this fine product. I do have to feed a lot, 1 lb per 1000lbs but it is cheaper than treating Cushings and EMS!

Excellent for my older horse

This feed is what’s working for my 20+ year old gelding. He gains weight super easy and now in his older age has developed a crested neck and metabolic issues

This feed is what’s working for my 20+ year old gelding. He gains weight super easy and now in his older age has developed a crested neck and metabolic issues. This feed tastes good (to him) and only gives him what he needs and no more! I can only get it from Chewy which has been a God send for him since we don’t live near a reseller. Between this feed and his thyroid medicine, he looks really good for as old as he is. Thanks KER and Chewy.

I needed a ration balancer for a laminitic donkey which is not easy to find. This product from KER is perfect. He eats it just fine; his condition is improved and no side effects. I am feeding it at half the horse rate since it is a donkey and it seems to work really well. Having the convenience of Chewy delivery is just fantastic!

Perfect for easy keepers

I can never find a ration balancer in the feed stores around here. This is perfect for my high energy horse who doesn't need the extra calories or energy of grains

I can never find a ration balancer in the feed stores around here. This is perfect for my high energy horse who doesn't need the extra calories or energy of grains. This balances her diet without hyping her up.

Best ration balancer

My horse is insulin resistant. This has been a game changer and beating him. I highly recommend it.
