Purica Equine MSM (1 kg)

Purica Equine MSM (1 kg) is pure methylsulfonylmethane powder for horses, sold in a 1 kg resealable pouch and measured in 10 g scoops. The MSM is plant-sourced, the powder is vegan, and it is made in Canada under Purica's Equine line.

What is in the pouch

The label defines one scoop as 10 g, or one tablespoon, and each scoop holds 10,000 mg of MSM. MSM is the only ingredient. Purica states that the powder has no artificial ingredients, preservatives, additives or common allergens. Methylsulfonylmethane is an organic sulfur compound; horses also take in small amounts from fresh forage such as alfalfa and grass.

Feeding rate

Start slowly and build up over two weeks to half a scoop per 300 lb of body weight. Give it by mouth once a day, during or after a meal; most owners stir it into grain, pellets or a damp mash. After 30 to 60 days the label says it may be possible to drop to a quarter scoop per 300 lb.

For a 1,200 lb horse the full rate is 2 scoops (20 g) a day, so a 1 kg pouch lasts about 50 days. At the lower quarter-scoop rate the same horse uses 1 scoop a day and the pouch lasts about 100 days. A 600 lb pony needs half those amounts.

Storage and handling

Keep the pouch in a cool, dry place and do not use it if the seal is broken. MSM pulls in moisture and clumps if the bag sits open in a humid barn, so press the air out and close the zip after each feed. The label also states that the product is not for use with animals intended for slaughter.

Equine MSM and MSM for people

Purica sells MSM for people in jars, pouches and capsules. This pouch is the horse version: it is labelled for animals, dosed by body weight in scoops, and sold in 1 kg and 5 kg sizes. The 1 kg pouch suits a single horse or a trial run before buying the larger bag.
