I use naff slim as I put my horse on soaked hay to maintain a good weight before and during spring grass it replaces what I take out with the sugars and helps reduce any fat pockets or cresty necks this is my 3rd season using naff slim and would recommen as part of controlled diet for hoses prone to weight gain easy to use but found we have to start with small amount then build up to daily recommendation

Hi there. If using NAF slim do you still feed a low cal balancer or does this provide everything they would need vitamin and mineral wise? Many thanks

  • VioVet Staff

I have contacted the manufacturer regarding your query who has advised the following:
We are pleased to advise SLIM contains a blend of herbal ingredients to naturally provide a broad spectrum of vitamins and minerals for health and wellbeing. So the weight conscious equine on SLIM does not require another multi-vitamin.

How dose the naf slim works and how long will it take for the horse to lose weight

  • VioVet Staff

This product only works if given with very high fibre, low calorie foods. It is designed to make sure that your horse gets all the important nutrients it needs in its diet to stay healthy. This means that you can then feed very little other food. Therefore your horse will lose weight at a rate in proportion to how well you restrict its other food. Restricted grazing on relatively poor pasture, or just high fibre foods are then all that is needed to achieve weight loss, but it might seem a bit "mean" if you are kind hearted. Weight loss pretty much always comes from consuming less energy in total.
