Omega Equine Biotin Extra – 2kgBiotin Extra is Omega's hoof supplement for horses with cracked, brittle or shelly feet that struggle to hold a shoe. A 50g daily serving supplies 15.5mg of biotin, and the biotin is backed by DL-methionine at 18,000mg/kg, zinc at 280mg/kg and 9,600mg/kg of MSM — the sulphur-bearing nutrients hoof horn is actually built from.At the full 50g rate a 2kg pack lasts about 40 days, so this is a supplement bought by the season rather than the week. Hoof horn grows down from the coronet over the best part of a year, so judge it over months rather than weeks.Performance & Benefits 15.5mg of biotin per 50g daily serving, one of the higher rates in the Omega range.
