Use 100g a day per 100kg ideal (not actual) body weight, divided between two feeds. For example, 500g per day for a 500kg horse.

Quick soaking, use 2-2.5 parts water to 1 part feed.

For best results, feed MetaSlim as part of a complete Simple System diet.

Pulpits Farm have been loyal customers of Simple System for over 20 years.

We have been thoroughly pleased with the products & service offered to us over the years  and have found Simple System Horse Feeds to be perfect for the wide range of different breeds we have here; including Arabs, Thoroughbreds, Highlands and other Native breeds (many of whom live out 24/7).

Gill Robinson, Essex

She’s been on MetaSlim for nearly two years now and the results have been fantastic. She has lost a lot of weight and I find it much easier to keep the weight off. She feels a lot more supple in her neck and across her back too. I wouldn’t change from MetaSlim now. It’s so easy to order and it arrives so quickly.

Miss Sarah Brown

We switched Zippy onto Simple System Horse Feeds as we were struggling with persistent fat pads, rocketing insulin levels and her being stiff and footy. We took advice from the Feed Line (who are always extremely helpful!) and switched her over to MetaSlim and Sainfoin Fibre Pellets.

Miss Helen Yeo

14 year old, Irish Cob, Sally, was overweight and contracted mild laminitis in February.

We started her on Simple System MetaSlim, as well as the Sainfoin Fibre Pellets twice a day. The amount of weight she has lost is unbelievable! She is feeling a lot better too! Would definitely recommend!
