From our customers


I can't say enough good things about Frog Fuel. I am a triathlete and use all the Frog Fuel products for different stages of my training. I recommend these products to all the athletes I train!

Deborah S.

Hands down the best supplement on the market. Significant increases in strength, fewer injuries, and faster recovery. I have been taking this product for over 3 years and would not think about changing.

Lee A.

I've been working out for over 50-years and during that time I have tested numerous vitamin and protein supplements. I have found that both Frog-fuel and ProT Gold not only taste great, but are also the most effective protein supplements in supporting muscle healing (rebuilding) and fueling energy.

Richard T.

I do long endurance runs and obstacle course races, and have been looking for the perfect protein. This is it! Easy to carry, easy on the stomach, and is a great complement to my carb/electrolyte drink. Worked great for the Chicago marathon and my first trail ultra.
