    BioFlax 20 is rated 4.7 out of 5 by 161.
    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.

    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.

    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.

    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.

    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.

    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.

    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 .
    Date published: 2016-07-25
    Rated 5 out of 5 by from Works really well! I put my 18 year old OTTB on this 2 months ago because his hooves were showing very poor growth and were cracking terribly. He had tremendous healthy growth his past cycle and his hooves are looking better than ever! My horse is extremely picky when it comes to supplements and he gobbles it up!
    Date published: 2016-07-02
    Rated 5 out of 5 by from My horse's coat has never been shinier This product was recommended to me by a friend when I mentioned wanting to put my horse on a hoof and coat supplement. The price was very affordable so I decided to give it a try. My horse is picky when it comes to anything that isn't pelleted so I wasn't sure if he'd eat it but I haven't had any problems, he loves it. I was noticing a difference in his coat within just a few weeks! I am pleased to say that his coat has never been shinier than it is right now while on this supplement. I wish I could say I saw as big of a difference with his hooves but I don't notice much change there. He doesn't have terrible feet to begin with though. Regardless, I would recommend this product.

    Rated 5 out of 5 by from Good product Bought this to put my mare on that had to have her hoof resectioned, because of white line disease, vet recommended a biotin supplement to increase hoof growth. My mare is picky but is eating this just fine mixed with her feed and her hoof growth is doing well. Plus her hair feels great too.

    Rated 5 out of 5 by from Great for my ottb I chose this product because of budget and the great review it had. But I am so happy I did. I recently rescued a thoroughbred straight from the track. Before pulling my geldings race shoes I opted to start him on this to help his hooves once barefoot. Well 60+ days on this supplement and barefoot his hooves are holding up fantastic. Not to mention is his coat is beautiful and shinny. My boy is not a fan of brushing so I know his shinny coat is a result from the bioflax

    Rated 4 out of 5 by from Shiny healthy coats I purchased this product and have used only about a month. The horses were looking pretty slim, dull coats, and one horse has soft soles. Their coats are looking much better, and the gelding seems to be putting on some weight. I am not sure about helping soles yet, as it is still early. The trainer even noticed how much better they looked!

    Rated 5 out of 5 by from Great Results! My mare has been on this supplement for almost a year and I am very happy with the results. When I got her a year ago, she had a short, scruffy tail and dry, cracked, chipped hooves. Using this supplement along with coat and hoof conditioners, I noticed a difference in her coat within weeks. Her hooves began to improve within a couple of months and her tail has grown out and is thicker. She did have to get back shoes put on but is in work year round and has your typical Thoroughbred hooves. Overall they are greatly improved and she no longer loses shoes. She eats this supplement no problem but is not picky.

    Rated 4 out of 5 by from Shines coat I wanted to add flax to my horse's diet for coat shine. This product offered good levels of flax and biotin for the cost. After feeding for about 4 weeks I can definitely see more shine on my horse's coat. It will take a lot longer to see if this product helps with hoof or tail growth. My horse seems to eat the powder with no complaints, but he generally isn't picky.
    Date published: 2016-03-17
    Rated 4 out of 5 by from Excellent combination of flax and biotin I just reordered a bucket. It is palatable, and contains ground flax (better for teeth than whole) and a good amount of biotin. Many biotin products don't contain enough to make a difference. The only troubling side is the smell when first opened. Let it breathe before feeding.
    Date published: 2016-02-02
    Rated 5 out of 5 by from Great product Love the fact that this one product does the same as two products I was using before, and in a smaller amount.

    Rated 5 out of 5 by from Great buy Bought this over a month ago and I am extremely happy with the product I have seen a considerable amount of growth in my horses mane, tail, and hoofs. I love the smartpaks so easy to use . They are quick easy and no mess.
    Date published: 2015-09-10
    Rated 5 out of 5 by from So Shiny!! My horse's hair and coat quality have both greatly improved!! He shines like a new penny, and his mane has grown over an inch, just in the 45 days he's been on it! In love with Bioflax!
    Date published: 2015-08-12
    Rated 5 out of 5 by from My horse eats it! This has enough biotin to be a good hoof supplement, I tried it because I also wanted my horse to have flax and the omega 3. It's economical. I pulled back shoes in April and feet look great all around.
    Date published: 2015-08-06
    Rated 5 out of 5 by from Hoof and coat! I switched to this supplement from the more common Farrier's Formula Double Strength in order to alleviate the strain on my wallet. I am more than happy with the results! My horse's feet have remained healthy, been holding shoes well, and my horse is GLEAMING! I love that this supplement has less ingredients, including flax (which has so many additional benefits!), and that it has 20g of biotin (one of the highest amount of biotin compared to other hoof supplements on the market). Overall I am a happy customer! My only complaint is that it's sometimes left at the bottom of my horse's bucket...but that could very well be due to the electrolyte he gets and that he gets a very small amount of grain.
    Date published: 2015-06-07
    Rated 5 out of 5 by from Fast results! It has not even been a full 28 days (maybe close to 20-22) with my mare on this supplement, but I already see amazing results! Her hooves are still recovering from years of neglect and so I decided to try this because I saw it not only supports healthy hooves, but also skin and coat as well for a great price. Just the other day I picked her hooves, and saw pretty patterns and colors I didn't know she even had, as well as a much improved frog. Her skin used to be flakey, not anymore. Her coat used to be dry and dull, but now vibrant and soft! Can't wait til she's all shed out to see what her summer coat will look like!
