I've been using these for years and feel they give me a good foundation for my health.
Easy to take and and did the job. Meant I could drink plain water without missing out on electrolytes
My go to product to supplement my electrolyte needs.
Easy to use and nice taste.
On Saturday 14th September I stood on the start line at Bewts Y Coed. This was my 3rd 100 miler this year.
I have used Hammer since around 2010 in my Ironman days. As of today I have completed 428 marathons ‘all official races’ around the globe.. also quite a few ultras in my time.
I have used Recoverite on multi day ultras for the last 10 years. Great mix and flavour. I have converted many to this product.
Seems to be really helping recovery from my knee strain. I had a similar issue a couple of years ago which took weeks to sort. Fair do’s it doing what it says it will.
Tasty and light on the stomach.
I will definitely order many more of these
Great electrolytes and gentle on the stomach.
I have a sensitive stomach but these products are the best I have tried.
