Product Uses
Recommended Usage

This product is designed to be consumed within 30 minutes post-exercise and not mixed with milk as it will slow down the absorption rate.

Carbohydrate is your body's main fuel for moderate to high intensity exercise. During training and competition, our bodies can absorb around 60g of carbohydrate per hour, meaning that demand will outstrip the supply of energy. This shortfall is met by using your glycogen stores, which must be replenished post exercise so you are able to perform well in your next session.

REGO Rapid Recovery contains high quality protein with a complete amino acid profile enhanced by the addition of 2g of Leucine. A vitamin and mineral profile has also been included to support the recovery process by contributing to normal muscle function and protein synthesis

Tastes good and seem to notice a difference if I don't take it after a hard ride, less aching and better recovery.

Carwyn Wooldridge

I love Banana Milkshake & this is a brilliant recovery drink, considering you use water & not milk it tastes & feels like milk when not. Also gives brilliant recovery.

Tasty as f***. Really like it!

Helen Raymond

Just what I need for half marathon training recovery.

Steven Hyams

Tried it 3 times after of mer, long rides - 35 miles - Im 63 and improving. Usually the next day, I need a break and feel tired but taking REGO as suggested within 30 minutes - a significant difference in recovery (I am an engineer by training so the need to be precise-ish). Chocolate flavour, with water, in the fridge - magic potion AND it tastes very good.

Timothy Ranger

Honestly, I think that products like this are a little overpriced, but the SiS variety is good value amongst its peers.

Alison Archer

I was a bit worried when it the powder was to be mixed with water only, but it actually made quite a tasty drink. Would recommend it

Vinicius Vecchiatti

Game Changing - Two Words. That Simple

paul davies

Improves your recovery. What more do you need?


I got a tub of this thrown in from a previous order and really liked it, so purchased another. I mix a bottle full the night before a long ride and then consume after the ride, which by a long ride I mean for me above 50 miles, and although I don't feel any difference after the ride from the rego, the next day I have no stiffness or even feeling sore and tired muscles which I can have if I don't use the rego, all in all good stuff I think

Lee Mcgee
