  • • Additional 5g of L-Glutamine
  • • Use after exercise to replenish your energy stores fast

Product Uses
Recommended Usage

Consume 1 x 70g serving (3 heaped scoops) of REGO Rapid Recovery Plus within 30 minutes of completing your tough training session/competition. Mix with 500ml of water, mixing it with milk will slow down the absorption rate.


REGO Rapid Recovery Plus contains high quality whey protein concentrate, which has a complete amino acid profile to which we have added an additional 2g of leucine and 5g of L-Glutamine to support muscle protein synthesis. Leucine is an amino acid which is known to switch on the signalling for muscle protein synthesis and L-Glutamine is known as the one of the most abundant essential amino acids, with anti-catabolic and immune properties. The blend of carbohydrate, protein, L-Glutamine and BCAAs thereby provides a recovery formula that can promote replenishment of muscle glycogen stores, muscle protein synthesis, gut function and rehydration. 

Carbohydrate is your muscles main fuel for moderate to high intensity exercise. During training and competition, our bodies can absorb around 60-90g 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.

When should I take this?

  • REGO Rapid Recovery Plus should be taken within 30 minutes for finishing exercising. It should be taken after high intensity or prolonged training sessions and competition where you have depleted your carbohydrate energy stores. It is highly relevant for those athletes who need to recover quickly in order to prepare for another training session or competition period.

What is the difference between REGO Rapid Recovery Plus and REGO Rapid Recovery?

  • REGO Rapid Recovery Plus provides all of the benefits of REGO Rapid Recovery, but with increased carbohydrate content, use of whey protein and inclusion of additional Leucine and L-Glutamine. REGO Rapid Recovery Plus should be considered by athletes who are looking for an 'all in one' product to facilitate recovery after intense exercise by simultaneously promoting muscle glycogen re-synthesis, muscle protein synthesis and rehydration. It is relevant for both endurance and team sport athletes.

What is L-Glutamine?

  • L-Glutamine is the most abundant non-essential amino acid found in muscle tissue. During periods of prolonged and intense exercise, both blood and muscle stores of glutamine can become depleted and remain reduced in the post-exercise recovery period. Glutamine is also an important energy source for immune and gut cells.

What does L-Glutamine do?

  • L-Glutamine supplementation can help replenish the diminished Glutamine stores post-exercise. Glutamine supplementation before and after exercise may therefore improve muscle (promoted muscle recovery), immune and gut function.

What are the benefits of added Leucine?

  • Leucine is the main BCAA that is used to produce energy during exercise and is also the key amino acid that stimulates muscle protein synthesis in the post-exercise recovery period.

What is the difference between REGO Rapid Recovery Plus and Whey Protein?

  • Use REGO Rapid Recovery Plus when the aim is to quickly replenish your carbohydrate energy stores alongside promoting muscle recovery by also consuming protein. If your goal or activity does not deplete energy stores but you are still aiming to maintain muscle mass and promote muscle recovery by stimulating protein synthesis, then Whey Protein may be a better option.

What type of protein does this use?

  • REGO Rapid Recovery Plus uses whey protein concentrate, which is a high quality protein source that is rich in BCAAs.

Why isn’t it suitable for vegans?

  • REGO Rapid Recovery Plus contains milk (whey protein concentrate) and is unsuitable for vegans.

How many scoops per serving:

  • Add 70g (approximately 3 scoops) to 500ml of water and mix well.

How much protein is there per serving?

  • REGO Rapid Recovery Plus contains 24g of protein in total.

Does it mix/shake well?

  • Yes, but for best results, mix with an SiS shaker

Good tast and easy on stomach


Great taste, easy to drink, not sure how my recovery would be without this but seems to work

Mr Robinson

Regular user after a long ride. It works for me.


I've used REGO for approx 5 years, By taking it as compared to not taking it within 30 minutes - the next day is so different. Taking it as soon as possible after getting home means that tomorrow my legs are still stiff from yesterdays exercise but are able to push just as hard on long hills/short sprints etc. If I ride away from home and wasn't taking it till 1 - 2 hours after cycling then tomorrow ( ignoring the ache from yesterday) my legs feel dead with no "get up and go" and long climbs were depressingly loooooooong.

steve gibbons

This really hits the spot, always gives you that bit extra

shaun heys

Great tasting for such a complex shake. Provides all post ride nutrition and feeling of replenishment after hard riding.


Reasonable taste compared to some competitors. Seems to do the job: I generally don't ache the day after if I use this after cycling. Has occasionally caused mild gut issues for me which is why it doesn't receive 5 stars.

Gregory Patmore

Protein is an important recovery supplement. The chocolate flavour is delicious

leona goulder

Tastes great


Terrible taste - I was so expecting normal REGO and got this instead.

alex d

Works great!

Unhappy of Arundel

Great taste and great impact.

Andrew Mant

Tastes great, and really speeds up recovery!

Ricard Torra-Prat

Very good, as expected

Emily Reeves

My favourite flavour, muscles dont feel achey the next day and has helped build muscle.


Good stuff

Grant Skelton

seems ok but doesn't mix as well or taste as good as normal Rego?!

Mehdi Bennani

best product so far. recovery mix with protein, bcaa, minerals and vitamins.


I have always given Chocolate flavor 5 stars up until I tried the lemon, Chocolate is still just as good but there is no 6 stars for lemon

steve gibbons

Good flavour, and something you can trust


I tried the Rego Rapid Recovery a while ago and found it very good in helping with my recovery after strenuous exercise. I thought that if that was good the Rapid Recovery+ would be even better. MIstake! Mixing the recommended quantities of powder to water makes a drink that tastes like overly diluted hot chocolate powder. Not only that - no matter how long I shake the drink for I cannot get the powder to dissolve fully which results in the drink being full of bits that make it unpleasant to drink. I would not buy it again.


This is just what I have been after for dome time. I had finished my previous supply do ordered a double quantity.

Grant Paul-Florence

I enjoy the taste of this too much. But that’s helpful because it really helps me recover and rebuild between bike rides

Ms Angela Eglesfield

The mix is watery, prefer the thicker mix of Rego alone




I am 62 and have been training for 45 years. I started to get tired after training so I started using this. Not only am I no longer tired, I am seeing gains. Wish I'd used it years ago.


Best protein/recovery product available. Tastes great too.


The raspberry flavour is really good and it does seem to help with recovery after cycling. I use it after all interval training and rides exceeding 1 hour long. Would definitely recommend

Alex Dowsett

Yeeeeee recovery


Excellent recovery product does what it says on the tin, cannot fault it.

Julius Chang

Helps me recovered me tired thighs after a hard ride
