Questions & Answers

5 Customer Questions

Hi, are you also going to carry the 25 pound bag? Thanks
Answer by ChewyJul 29, 2020
At this time, the manufacturer only offers this supplement in a 5-pound bag.

How many servings per bag and does it come with scoop?
Answer by ChewySep 11, 2020
The GROSTRONG mineral is a 2oz per day feeding rate. The 5-lb bag will last 1 horse for about 30 days. The 5-lb bags should have scoops inside them.

What is the actual serving about of Vit E? The information says 3000iu/lb., not per serving.
Answer by ChewyJan 19, 2021
At this time, 3,000 IU/lb is the tagged vitamin E level in GROSTRONG Minerals.

What is the iodine and manganese level in this supplement?
Answer by ChewySep 09, 2022
This supplement contains 78% iodine and 5.5% manganese. (Percentage of a 1200 lb Horse’s Maintenance Mineral Requirements Provided by a Typical Trace Mineralized Salt Block Consumed at the Recommended Rate)

Great stuff....feed your horses hooves

Been using Adm Grostrong minerals with electrolytes and natural sourced Vitamin E etc. My horses eat hay and no fresh pasture so I can it use to balance their forage diet. Reasonable price too compared to others.

Senior Horse Approved

I've had my senior horse on this supplement for the past three years and I love it, but, Chewy recently went $4 up on the price. It being added to his already long list of supplements means that $4 is a deal breaker. I saw another review saying that Chewy doesn't offer as many deals/coupons for existing customers and I completely agree. New customers have a much better chance at "qualifying" for a "deal".

I like it but might have to switch

I love this, my horses love it, and it smells apple cider. I’m happy feeding this knowing that the horses are getting the extra minerals and vitamins that may be lacking from their hay diet. But the 5 lb bag doesn’t last long with 3 horses, and the price recently went from 15.99 to 19.99. Chewy really doesn’t give out a lot of coupons to their established customers, unfortunately, and they don’t carry the big bag. This brand is hard to find in my area. I’ll probably look for a different comparable product.

Good all around supplement

My fillies are eating this supplement and doing well on it. I wanted something to fill in any gaps they may have in their diet and this was the best product for the money.

I couldn't have been more excited to find ADM Gro Strong at the Chewy site. After winning this product at a horse show and using it on my then 2 year old, I was unable to find it at a feed store within 75 miles of my home. Chewy is the answer to my prayers.

I have been using this since it was Moormans. An excellent mineral formula that kept my horses looking fabulous. Too bad it is unavailable.
