BioFlax 20 is rated 4.6 out of 5 by 184.
Rated 5 out of 5 by from I’ve used it for years This is a great supportive supplement for hooves and coat. Benefits of omegas are talked about more and more and this is an affordable way to get them.

Rated 5 out of 5 by from Awesome Supplement This helps my horses grow better hooves!! Their coat is soft, and now I have to trim their mane, and tails!
Date published: 2020-04-14
Rated 4 out of 5 by from They like it! It's only been 1 month since my horse have been on it, so I cant say or tell if their a change. They are eating so that's good.

Rated 5 out of 5 by from Growing better quality feet My mare had very poor hooves that were breaking off and just poor quality. Tried other hoof supplement for 8 months it did nothing for her. My farrier noticed the difference in hoof growth and quality in just 2 months and he was very impressed. I won't run out of this product.
Date published: 2019-10-28
Rated 5 out of 5 by from Great results in just a month! I did a lot of research on which hoof/coat supplement was the best bang for my buck. I have four horses and I wanted something I could buy in bulk that was quality, but wouldn't break the bank. I'm super pleased with the BioFlax 20 - I've been feeding it for about a month and my horses are SO shiny (without any elbow grease on my part) and they're growing more foot. I'm especially pleased because my gelding that's been battling rainrot for six months is FINALLY growing a new coat, and he looks amazing. This stuff + proper diet = pure magic. Hard to find the correct serving of biotin at an affordable price, but here it is.

Rated 5 out of 5 by from Great supplement I decided to try this supplement to help my 5 year old Oldenburg with his hooves. They were dry and brittle. My farrier noticed at his next shoeing that there was a difference.
Date published: 2019-09-20
Rated 4 out of 5 by from Easy to feed and lots of hoof/hair growth I'm only giving 4 stars currently because I dont think I've been on it long enough to see the benefits, if any, at the bottom of the hoof. I will update if I think it does. His feet are growing quite fast though and his mane and tail actually have grown beautifully. Benefits of the biotin, his tail was always wirey with no body and now it's getting fluffy, his mane is thick and shiny as well. I like that the feed component is flax. Flax is something you cant really go wrong with adding into the diet and my horse loves it. He cleans his bowl so I don't care that it's not pelleted. This is a good supplement if you dont need to add copper or zinc into the diet. There isnt a lot of research on these ingredients, but if you have a horse with bad feet you know what it's like to try anything.

Rated 5 out of 5 by from Incredible glossy coat Noticed an improvement in horse coat, he absolutely shines.
Date published: 2019-05-16
Rated 2 out of 5 by from Didn't work for us My horse is on his second bucket of BioFlax 20, and I have sadly seen a decrease in his hoof and coat quality. He ate it, so I will say it's palatable, but I will be switching to a different product.
Date published: 2019-04-10
Rated 5 out of 5 by from Love this stuff! Love this product, my horse has been getting is for a few months now, her coat and feet look awesome!
Date published: 2019-03-20
Rated 5 out of 5 by from Awesome and Affordable! Absolutely love this product. My mare's coat is smooth and shiny and her hooves are staying strong and healthy, even during our dreaded "muddy season". I bought this product as an economical hoof supplement but have been thrilled with the other benefits. My routine also includes regular application of Farriers Fix Hoof Oil - my Farrier gives the combination two thumbs up!

Rated 5 out of 5 by from Excellent Product! I have used Horse Tech products off and on for years. They are always palatable, my horse lick their bowls clean, and I always notice results. The bioflax 20 definitely improves my horses hooves, skin and coat!
Date published: 2018-01-23
Rated 5 out of 5 by from Great dosing and effective! Excellent concentration of biotin allows for easy small dosing daily. In one month there has been major improvement in the strength of my OTTB hooves.

Rated 5 out of 5 by from Love this product. It's amazing how wonderful this works with just a simple ingredients love this product highly recommend it
Date published: 2017-10-28
Rated 5 out of 5 by from Wonderful! Bought this to help my horses already great feet, as I loved the omegas in the flax. Adding the biotin to the flax makes it a perfect overall omega supplement with added support for hooves and coat!! Super cheap too!
Date published: 2017-10-26
Rated 5 out of 5 by from quality product I read all the reviews and decided to try this product because it has the flaxseed and the biotin. My mare likes the taste and her hooves are healthy.
Date published: 2017-09-12
Rated 2 out of 5 by from Little difference The only thing I really noticed was his hooves. They were a little harder but as for his mane and tail, really there was no change. No growth or texture difference.
Date published: 2017-08-24
Rated 5 out of 5 by from Great and affordable We switched to this biotin, along with SmartCirculate, after seeing no hoof growth while using a much more expensive biotin supplement. Since switching to this, we have seen tremendous growth and strong hooves.
Date published: 2017-08-20
Rated 4 out of 5 by from Great product, not as many servings as listed I've been feeding this supplement to my horse for 5 years. I typically buy it in buckets, but have done SmartPaks as well. About a year ago I started tracking when I started a new bucket to figure out how many servings were actually in each one, since it seemed like I was ordering more frequently. Almost every time, I was getting around 58-60 servings per 5lb bucket which advertises that 5lbs = 80 servings. I still love the product, but worth noting it's not as big of a bang for your buck as listed.

Rated 5 out of 5 by from Absolutely fantastic I had bought Bioflax 20 several years ago also. AAA++++ supplement. My horses coat looked absolutely beautiful - shinny, healthy, gorgeous looking!! I don't have shoes on her. Went for a trail ride that had a lot of rocks. The next day she wasn't even limping like other horses who did not have shoes on either and she has white hooves. This supplement definitely does what it states it will do.
Date published: 2017-06-12
Rated 5 out of 5 by from One of the highest amounts of biotin on the market, and paired with flax seed it's a win win.
Date published: 2017-04-06
Rated 5 out of 5 by from Works great for my OTTB feet Switched to the product for the higher biotin concentration. Has worked wonderfully on my OTTB's feet that used to crack a lot.
Date published: 2017-01-18
Rated 4 out of 5 by from Good product I've been using this for a few months now, after looking for something cheaper than farriers formula, and it has been working about as well for my horse.
Date published: 2017-01-10
Rated 5 out of 5 by from Works Great! I have had my horse on another popular hoof supplement for years but she still had cracks and her feet crumbled close to trim time. So far her hooves are looking great on this stuff and she doesn't seem to mind that its a powder. Eats it right up!
Date published: 2017-01-02
Rated 5 out of 5 by from Good quality product I purchased this supplement because it has biotin and omega fatty acids, and because a friend confirmed it was helping her geldings' hooves. My picky mare likes it and I expect that it will work for her hooves and her coat and skin. The product was delivered on time.
Date published: 2016-12-12
Rated 5 out of 5 by from Work well! Bought this a month ago for our 28 years Arabian cross gelding that was getting abscesses in his one front hoof, no one could figure out why, vet, farrier extra. Finally the farrier suggested Bio Flex, so we gave it a try and no more signs of abscesses.
Date published: 2016-09-23
Rated 1 out of 5 by from over a year I have a large draft warmblood cross. This product I have fed in smartpak to my gelding for at least a year hoping it would finally work. No results. Wears hoof down faster than it can grow. Cracks, etc.
Date published: 2016-08-14
Rated 5 out of 5 by from Tons of growth Bought this for my TB mare who was having some highly unusual foot issues for her and had tremendous cracking and splitting and splaying. Switched shoes and put her on this to help jump start some foot growth to help blow out the cracked areas of her feet. My farrier pulled her shoes, stopped, looked at me and asked what the heck I gave her :). She grew enough we were able to almost completely correct the issues in one cycle. Her feet are back to looking awesome like they used to. Have also stuck my OTTB on this and he did show some growth, but not as much (normal for him as he isn't as prone to quick reactions to supplementation like my mare). 100% will recommend to clients and friends.
Date published: 2016-07-26
Rated 4 out of 5 by from I bought this for my mini but he wasn't on it long enough to notice a difference but his coat did seem healthier.
Date published: 2016-07-25
Rated 4 out of 5 by from Very palatable I added this supplement to an existing smart pak because it was so economical. My horse had no problem eating this additional supplement .
