While it is not advertised that Perpetuem contains electrolytes, a quick glance at the nutritional info will show that Perpetuem does contain the same minerals as the Endurolytes do. However, the majority of those electrolytes will go to the digestive process, so warm to hot conditions will warrant additional electrolytes. When riding in cool conditions you can forgo the additional capsules, although it is a good idea to
carry capsules with you just in case.
Some athletes using Perpetuem, but not all, who normally use only 1-2 Endurolytes per hour may be able to go without Endurolyte supplementation. The self-contained electrolytes profile in Perpetuem is therefore equivalent to 1-2 Endurolytes per hour dose, depending on the individual athlete.

Perpetuem contains : Endurolytes dose 1-2 capsules per hour
