SOURCE Nuggets is rated 4.8 out of 5 by 45.
Rated 5 out of 5 by from Overall good supplement for my horse I've used Source Nuggets for many years-I started when I felt my horse might benefit from an overall supplement to her nutrition and to help strengthen her hooves. I use it as a daily "snack" and she loves it.

Rated 5 out of 5 by from Great mineral and micronutrient boost! I love this product because my horse was having some issues with nutrient deficiency and poor condition and this supplement made a huge difference! I found that a lot of soil and feeds are deficient in some minerals and nutrients and this supplement provides a good broad spectrum to cover most bases and enhance the diet for any horse. In conjunction with a balanced diet, this supplement has helped my horse maintain health and condition. She eats these pellets with no problem, and I love that I don't have to feed a powder. My horse's coat is shiny, her mane and tail are thick and flowing, and her hooves are sturdy and healthy. Thank you Smartpak!

Rated 5 out of 5 by from An Oldie But Goodie I had used Source back in the old days almost since it first came onto the market. My mare needed a little boost in immune support and hoof condition so I decided to revisit Source. I am very pleased that I did. My farrier noticed an increase in healthy hoof and hoof growth within two weeks after I started feeding Source to my mare. An extreme case of mud fever that she's had since I got her over a year and a half ago is showing some signs of improvement. Her overall condition is excellent. Even her winter coat is dappling. I'm not sure why I stopped using Source but it will be a regular part of my feeding program again from now on.

Rated 5 out of 5 by from Used for over 20 years I have used Source for over 20 years on all my horses. I think it helps with overall hoof strength and general health.

Rated 5 out of 5 by from More expensive than the powder but worth it My horse was always good about eating the Source powder but I felt like there was more of the possibility of it getting stuck in his supplement containers or in his grain bucket that gets poured into his feed tub. Having pellets instead of powder prevents this problem. They smell a little fake & funny but my horse likes them & I don't worry that he might not get his full ration each time.

Rated 4 out of 5 by from Any horse, anywhere Source is a great basic nutrient mix for any horse. I have used it for years and will continue to do so.

Rated 5 out of 5 by from Gotta love Source I absolutely adore Source... have seen some really incredible changes in my horses in the first two or three months on Source. Really soft coats, bright eyes, filling out well despite no change in feed amounts... etc etc. This was my first try with the nuggets because my picky mare dumped the powder on the ground. She ate it right up! Made me a little more comfortable too, knowing it got into her.

Rated 5 out of 5 by from Wonderful supplement! Ok, so it smells like bubblegum, but every horse I've given it to, likes it just fine. Nothing fancy, just seaweed! I have yet another very happy horse.....
Date published: 2012-02-20
Rated 5 out of 5 by from Extra something special from Source I have used Source for years. My horses have always looked fit, but adding Source really gives them a super healthy look. I love giving it in Smartpacks, as it easier and I know it is very fresh.
Date published: 2012-02-15
Rated 5 out of 5 by from Micro Nuggets - easy to 'serve' These nuggets completely disappear when added to my horse's feed. As a discerning detective, he sifts most powdered supplements to the bottom of his bucket. (I suspect he chuckles to himself seeing me toss out the unconsumed particles.) Source has always been an important ingredient, and this form of delivery is much better than the powdered version.

Rated 5 out of 5 by from Great benefit of feeding Seaweed Source products provide seaweed which contain concentrated micronutrients that are depleted on land. All animals and humans can benefit from blue-green algae products. I primarily give my horses Source products to provide nutrition for the thyroid, but there are other benefits too. I buy the large container of Source and it last 6 months for three horses. I've used Source Focus original, Source Micronutrients pellets, and Source Senior. I noticed recently Source Hoof contains Lysine which helps hoove and muscle health, so I will try that too. They eat all of these formulas very well. Source is green food and horses love green food! Some formulas are powder, and some are pellets, but you feed such a small amount that it doesn't matter.

Rated 5 out of 5 by from It's completely eaten! I've used the powdered Source for several years and it always seemed to be at the bottom of the feed bucket. I never knew if my horse got any or not so I decided to try the pellets. What a difference! The pellets are always GONE with the rest of the feed so I know she's getting the supplement and I'm not throwing my money down the drain. It's more expensive, but probably not in the long run since I threw so much of the powder in the garbage!
Date published: 2011-11-16
Rated 5 out of 5 by from Really good support It has all the advantages of the original Source but in pellet form. So it is great for horses who don't like powders. My horse did great on this supplement. Would recommend to anyone as a great overall addition to any horse's diet.

Rated 5 out of 5 by from Really good all-around health tonic I have been using Source for years and am convinced it has cured or helped to cure several equine ailments that my horses had/have and is a general health "tonic" for my horses. I've read several times over the internet to see the benefits of Source, put your horses on it for several months, then take them off and see the difference in their coat, hooves and general health and attitude versus when they were on Source. This is the one supplement I will have my horses on forever over all others.

Rated 4 out of 5 by from good supplement Good supplement, very tasty for the horses, but changed to a controlled vitamin

Rated 5 out of 5 by from Great all around supplement My PSG horse is the shiniest he has ever been with this product. Great!!! Love it. Have used it on and off since I was a child for my ponies. Thumbs up!
Date published: 2011-05-31
Rated 5 out of 5 by from The only supplement you need! I have been giving Source for 27 years to my event/hunting horses. They have always been very healthy and lived long lives. I have a Dutch Warmblood, a Thoroughbred & pony right now and they are all over 20. Since I discovered Smart Pak I have been saving money. They are the best!
Date published: 2011-05-23
Rated 5 out of 5 by from Good Product I have a horse that doesn't do well with powders in his grain. Having Source in a pelleted form is excellent.
Date published: 2011-02-13
Rated 5 out of 5 by from Source Nuggets I have been using Source Nuggets for 8 years now; my farrier and vet are always amazed how great my heard of horses look. They love the nuggets! and i love SmartPak they ship for a great flat rate and this is so helpful when ordering 75 lbs or more at a single shipping.

Rated 2 out of 5 by from I liked the idea of the Source so I bought it for my horse. He wouldnt eat the power so I switched to the pellets. He eats them without a problem but I have not noticed any difference in his coat at all...slightly disappointed after reading all the great reviews on this product..might switch to something else..
Date published: 2010-10-11
Rated 5 out of 5 by from wonderful stuff! Years ago I used Source, as in the powder. I wasn't sure if the horses got it, as it was so fine. I can see that the horses have eaten this, even mixed with their grain. It's great stuff!
Date published: 2010-09-13
Rated 5 out of 5 by from Good Choice Have used powered Source in the past, but I have a horse that is picky about eating powered supplements. Glad that Sourse comes in pelleted form. He now eats every last one!

Rated 5 out of 5 by from Good Choice for Pastured Horses and Easy Keepers I first started my mare on the Source Focus Hoof because she had cracks, and since she lives outside 90% of the time and is an easy keeper she needed a multivitamin also. After about 5 months all of the cracks are gone, she is barefoot, and I switched her to the original Source. Her hoof quality is still excellent several months later and her coat, stamina, and personality are much improved from when I first put her on the supplement. I would recommend this to anyone with an easy keeper or a pastured horse that doesn't get much grain. It did take a little while for her to get used to the taste, but she eats the original Source much better than the Source hoof.

Rated 5 out of 5 by from Keeps my horses healthy I have used Source ever since I was a kid. It's economical to use, the horses like it and it's easy to feed. I have seen a huge difference in my horses hooves, coat and overall condition with this product. It's great stuff!
Date published: 2010-01-01
Rated 5 out of 5 by from Excellent Product I have always used Source through my twenty plus years of horse leasing and owning. I think it provides an excellent base of trace minerals not neccessarily available to our horses anymore in their everyday hay and grain, and I have been able to see a difference in temperment/work ethic when horses are on Source. I've never had a horse with problem feet, but then they have always been on Source since day one. I currently use the pellets because my horse doesn't like the powder. I never had a problem with the powder in any previously owned horse, but my current guy doesn't like powders, and dislikes many pellets. I am glad Source offers this in pellets, since he does accept it a little better than the powder.
Date published: 2009-12-07
Rated 5 out of 5 by from Excellent Value and works great I've always liked the Source products, but I really like the pellets because my horse eats them more readily than the powder. They smell terrible, but he doesn't seem to mind that. I will say that the ingredients for all Source products regardless of whether they are labelled for hoff/weight gain, etc. are all the same, so you might as well buy the least expensive one that your horse will eat.
Date published: 2009-09-03
Rated 5 out of 5 by from Excellent product Source has been part of my mare's diet since she was born 18 years ago, and her companion also takes it. I partially attribute their excellent health and condition to it.

Rated 5 out of 5 by from Good supplement This was recommended by my vet because my sorrel gelding had white spots all over him (not an appaloosa), diagnosed as copper deficiency. Within one month spots faded almost completely. Tried to stop supplement and they returned

Rated 5 out of 5 by from Source Nuggets I have used Source Nuggets for 3 years now. I switched to nuggets form from the original formula that I had already used for 10 years. My horses find this form very palatible. I believe that it balances out my horses dietary needs. Their coat, hooves and health seems to really have benefited from Source.
Date published: 2009-04-20
Rated 5 out of 5 by from A great product Definitely a wonderful supplement for all horses! I noticed significant hoof, mane, and tail growth in my horse in addition to a lovely mirror-like finish on his coat.
