    SOURCE is rated 4.8 out of 5 by 130.
    Rated 4 out of 5 by from So far so good I have only been using this product for a month and I already notice an improvement in my horses' coats. More time will tell if there is a marked improvement in their hooves, but it does seem that surface cracks are growing out.

    Rated 5 out of 5 by from Long time Source user We have had horses for over 40 years. Started using Source in the mid eighties, I believe. Mainly for improved hoof quality, and also for better nutrient utilization. Sometime last winter we ran out for a few months, and Bob started going to pieces. After Spring shots, checkups, and some dental work, he is doing better, now; regaining weight and we hope his feet grow out with less chipping. Since we had started Pete on "Bug Off" earlier for his insect allergies, we decided to go with Smart Pak for their Source, as well. So far, so good. FYI both horses are in their twenties.

    Rated 5 out of 5 by from My secret... People have always commented on how shiny and healthy my horse looks. Every farrier I have had has commented on the growth and hardness of his hooves. He's never needed shoes. Of course, this could be a genetic trait but I think it comes down to a little of that, good hay, clean water, an appropriate amount of salt, regular deworming, and source. You gotta work from the inside out. Our soils are becoming more and more deficient in micronutrients which is why we must supplement in certain areas. I even carry this over to my own life and try to eat only organic foods which are better for the environment and my body. I try to get blood work done for my horse regularly and fill in gaps with more specific vitamins/minerals, like I do for myself, but in the interim I find this supplement seems to cover all the bases my horse needs. I've even used it on rescue horses in the past and they've all benefited from it. From OTTB's, quarter horses, Appaloosas, paints, and Arabs ranging from the ages of 4 to 30. Most got only that, not even needing a multivitamin. To top it off, this supplement is such a good deal. If you buy the cheap, small bucket, you get a 5 month supply and it doesn't need to be refrigerated. This is the one thing I've always recommended to first time horses owners. I'm glad my mom started me on this as a kid. I'll stick with this for any horses I own in the future.

    Rated 5 out of 5 by from Awesome sauce! I started my 27 year old TB on this a year ago when he kept suffering from recurrent rain rot. No more rain rot! Source also gave him a super soft, shiny, and healthy coat! He's shedding well this spring, and the hair underneath is beautiful! Both the powder and nuggets work well - it's up to you how you want to give it to your horse.

    Rated 5 out of 5 by from so far so good... I can't say I've seen drastic improvements yet but I have high hopes. Started this supplement about 1 month ago. I'm really hoping for better skin coats and stronger hooves. I will update this review in several months...

    Rated 5 out of 5 by from Don't knock it til you try it I've used Source for probably 20 years. It's just a good all around product. We give it to our brood mares and breeding stallions. I've used it on my riding geldings as well. I ride my horses barefoot. The Source toughens up the feet. I have to trim 2-3 times a year. My horses ride in all terrain, and have no problems. Good supplement for anything from foot problems, GI issues, and joint problems. You must feed for several months before you see results. It does work!

    Rated 5 out of 5 by from Won't go without Source! I purchased an OTTB gelding in December. He retired from the track in September and had some down time before I got him. He was shipped up from KY to ME and was a rack of bones. His coat was long and gross, and he had some sort if fungus on his neck. I started him on source immediately and his weight has picked up, he is gaining muscle, and his coat is shiny and beautiful! I can't wait to see how he looks by summer. He so g go without Source.

    Rated 5 out of 5 by from Provides wonderful benefits! I have had my 21 year old QH mare on this supplement since March and before that I had her on another version of sea kelp. Seaweed is full of vitamins and nutrients that benefit the horse! Last year at this time she had a hard time shedding out her winter coat. She stayed fuzzy for most of the summer in patches :( but this year is totally different! She is almost all shed out already and covered in dapple's and her pretty grulla coloring is vibrant this year! Also her hooves have started hardening up and her mane and tail have grown beautifully! I like to thank this supplement for bringing out the pretty in my mare :)

    Rated 5 out of 5 by from Great Product! I've been using Source for all my horses for years. It's a great product to help balance the nutrition of my mostly hay diet. My horses love it and the cost is extremely fair especially in the larger sizes.

    Rated 5 out of 5 by from Just makes sense.... I have used it for years. Peace of mind knowing my boys are getting nutrients that are most assuredly missing from our depleted crops.

    Rated 5 out of 5 by from My trainer recommended this product to help my horse maintain a healthy coat and hooves. She is an easy keeper and has a restricted diet, so it is important that she get all of the essential nutrients. This product insures she is receiving the trace minerals that are necessary.

    Rated 5 out of 5 by from One of the Best All-Around Products Out There I've used source with my OTTB for the past 7 years and it is an excellent product. There have been a few instances in which my horse has been off of Source for a couple of months at a time and I can certainly tell a difference. On Source his hoof quality is better, he has more hoof growth, his coat is shinier and more true to color and he maintains better body condition. Having a TB that is a bit of a hard keeper it is clear to me that he maintains his weight much more easily while on Source. I would recommend this product as an inexpensive way to help your horse maintain optimum hoof and body condition!

    Rated 5 out of 5 by from Source vitamins for your horse Our 5 horses do not have access to pasture so we want to be sure they are getting all the vitamins they need. Source is a fairly inexpensive way to do so.

    Rated 5 out of 5 by from Good Stuff! My Mare needs kelp to keep her thyroid level and I use Source instead of plain granulated kelp, which I used before, as the Source has a lot more in it. So far it has worked.

    Rated 5 out of 5 by from Trusted product I have used Source for my horses in the past. In recent years my hay has come from the same farmer and has been very high quality alfalfa mix. Given this year's poor hay growing conditions and the change from alfalfa mix (unavailable) to grass hay (I was plenty glad to get it) I added source back to their diet. I trust this product.

    Date published: 2012-10-06
    Rated 5 out of 5 by from Great product I don't know why I didn't try this product sooner. I had been using the industry standard for my horse's hooves and wasn't really seeing much of a result. My farrier had great things to say about this product, so i decided to give it a try. My horse's hooves are stronger, his coat is brilliant. Overall amazing product, a simple solution for a variety of coat and skin conditions, or an all inclusive dietary supplement.
    Date published: 2012-09-28
    Rated 2 out of 5 by from Not What I expected I had heard and read raving reviews for Source. All about how it improved horses health and overall general appearance. I had both my horses on it for 2-3 months and never noticed a difference. Most supplements you can see differences within 2 months, but not with this and the palatibility was poor, had to wet my horse's feed down in order for them to eat it. I am going to try Vita Plus instead. :(
    Date published: 2012-08-26
    Rated 5 out of 5 by from Excellent product I always use Source on all my horses, all ages, all breeds, performance horses or not. Seems like they always have nice coats, good feet and excellent energy levels.

    Rated 4 out of 5 by from Extremely Helpful!! For about six months, I had been unhappy with my horse's coat, and after doing some natural health research, came across SOURCE and decided to try it... My Quarab mare's spring coat came in with a dazzling sheen and I have never seen her look this good... wow!!I switched over to the pellets with my last shipment since I can't add powder to her pelleted feed, she won't touch it, but the product is great if you can get it into their system :D
