Magnesium Booster Bath Salts is rated 4.5 out of 5 by 25.
Rated 5 out of 5 by from Great for a relaxing bath These were a birthday present which I've just got round to trying as the weather is getting cooler and it's time for long soaks again. I don't like a heavily scented bath product or bath oils so this was ideal for me. The salts dissolve quickly and completely to give a relaxing treat.

Rated 5 out of 5 by from This works! I was given the advice to start using bath salts with magnesium by my physician to calm down the muscle tension. And this worked! I use it as prescribed (2-3 handfuls are enough) after a workout or a long-distance walk and feel how my body relaxes... Amazing product, I will definitely be repurchasing it.

Rated 4 out of 5 by from Not bad start I've only used it once so far. The package comes quite big, I think it would be enough for 10 baths at least. It doesn't have obvious smell, however dissolves very well in the warm water. As for the muscle relaxing function, I don't think it's so outstanding. Maybe I should try more times. Got it at a sales price, so not bad.

Rated 5 out of 5 by from Wonderful for muscle recovery After almost three months off games with an ankle injury, this has made my return to running so much less painful. Brilliant product: no scent, dissolves completely, works alongside bath oils (by any brand), and really helps with muscle recovery post-run/gardening. I will replenish stocks, but it seems to be lasting well, so no rush.

Rated 5 out of 5 by from The best Magnesium I have ever tried! The quality of this Magnesium is unsurpassed! It is a fantastic bath product that really gives results! The flakes are large and dissolve beautifully to give a mineral rich bath soak. Without fragrance and completely without additives, this is pure and unadulterated luxury!
