FAQS:
What is the difference between Perpetuem and Perpetuem Solids?
Perpetuem Solids use the same corn maltodextrin formula as Classic Perpetuem powder.
- A serving of 3 tablets provides 100 calories
- This is 10 more calories than 1 scoop of Perpetuem powder
Why use Maltodextrin instead of sugar in your fuels?
1. Better digestion and calorie delivery
- It provides the full amount of energy your body needs
- It moves quickly through the digestive system without delay
If you try to increase the strength of a sugar-based drink:
- It won’t match your body’s fluid balance
- It will sit in the stomach undigested
- This can lead to severe stomach discomfort
Maltodextrin avoids these issues.
Maltodextrin does raise blood sugar quickly and triggers insulin release.
However, this is not a problem during exercise because:
- The body reduces insulin release during activity
- Hormones from the nervous system help manage energy use
- Muscles take in glucose efficiently with minimal insulin
In simple terms, insulin is not a limiting factor during exercise.
Is sodium phosphate safe to consume?
It has FDA “GRAS” status (Generally Recognised As Safe) and is used in food as:
Toxicity levels (LD50) are extremely high. For example:
- A 75 kg person would need to consume around 555 grams to reach harmful levels
- This is far beyond any realistic intake
This shows sodium phosphate is very safe in normal use.
Do Perpetuem Solids contain caffeine?
Only the Caffè Latte flavour contains caffeine.
It provides 30 mg of caffeine per 3-tablet serving
What’s the difference between Perpetuem powder and Perpetuem Solids?
Same classic formula. The difference is the format:
Can Perpetuem Solids be your only fuel?

Helped on a climb in 34c heat…. Yum flavour too
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.
Another superb product from the Hammer Team. Dissolves so quickly with just a stir with a spoon or a quick shake in a bottle. Can feel the difference in sleep pattern for sure and energy levels have been more consistent with the mid afternoon lag not being as noticeable.
