I tried it at the end of the hunting season. I'd normally use redcell but the Naf one was on offer so gave it a go. Seems to be more palatable than redcell. Has a slightly minty smell to it.
I think it possibly took a bit longer to work, but it could be that Ron was more "end of seasonish" than i'd realised.
Would probably go for it again, as even not on offer it worked out cheaper than redcell.
I too normally buy the redcell but bought this as it was on offer, thought I'd give it a try, I've found the opposite from above, my mare did not like the taste of the Energ at all, she is not usually a picky eater and eats redcell no problem, in the end I had to add so much other stuff to disguise it! But in Naf's defence, when I told them about this they did offer to refund it!!! So respect to them.
But on another down note, it hasn't had even nearly the same effect as redcell did.
It is best to check the nutritional analysis, as they are not necessarily like for like. You can also work out cost per dose too to see which works out better value, even if one costs more than the other per bottle.
