Great Stuff

One of the most affordable and concentrated lysine supplements I could find. I feed this to my yearling and my working mare, both just need a little extra boost

One of the most affordable and concentrated lysine supplements I could find. I feed this to my yearling and my working mare, both just need a little extra boost while growing/training so they can meet their nutritional needs without feeding more grain. They both are muscled beautifully; I'm a repeat buyer!

Horse diagnosed with EPM and needed a Lysine boost. Luckily Chewy has this brand available. It's very palatable and the serving is miniscule, so this usually picky horse, is fine with it mixed in feed. The texture is between a granular and a powder. Have not had a horse ever refuse this Lysine mixed in feed. Much Thanks to Chewy for having it available.
