20 g Clear Protein Ready-to-Drink

Timing is one of the most discussed variables in sports nutrition — and for good reason. The post-workout period represents an important window during which the body is particularly receptive to protein for muscle repair and recovery. Protein Ready-to-Drink is designed to ensure that this window is never missed because of inconvenience. Each bottle delivers 20 grams of premium protein from a blend of whey isolate — selected for its high protein purity and fast absorption — and hydrolysed collagen peptides, which contribute not just amino acids but specifically the building blocks that support joint, tendon and connective tissue recovery alongside muscle repair.

With no preparation required and a format that fits in a gym bag, briefcase or car cupholder, Protein Ready-to-Drink removes every logistical barrier between the athlete and their post-workout nutrition.

Whey Isolate — High-Purity Protein for Fast Recovery

Whey protein isolate represents the purest form of whey protein — processed to remove the majority of fat and lactose, resulting in a protein source that is both high in protein by weight and rapidly absorbed. For post-workout recovery, where speed of amino acid delivery matters, whey isolate is one of the most effective protein sources available, and it forms the foundation of Sport Rx's ready-to-drink formulation.

Hydrolysed Collagen — A Unique Sports Nutrition Addition

The inclusion of hydrolysed collagen peptides alongside whey isolate in a ready-to-drink protein beverage is a deliberate and differentiating formulation choice by Sport Rx. Most ready-to-drink protein products focus solely on muscle recovery. By adding collagen, Sport Rx acknowledges that joint and connective tissue recovery are equally important parts of the athletic recovery equation — and uniquely valuable in the sport nutrition space.

Convenience Without Compromise

Sport Rx Protein Ready-to-Drink is a product where convenience and quality exist without trade-off. The same clean-label, no-banned-substances commitment that defines the entire Sport Rx range applies fully to the ready-to-drink format. Athletes who rely on these drinks for post-workout nutrition can do so with the same confidence they would have in any product from the broader Sport Rx stack.

FAQs

How much protein is in Protein Rx Ready-to-Drink?

Yes. The drink is formulated to be lactose-free.

Can diabetics drink Protein Ready-to-Drinks?

Current recommendations for sugar intake in diabetics generally advise that daily sugar intake should not exceed 10% of daily energy intake. The UK Scientific Advisory Committee on Nutrition further advises that the need for this percentage to ideally be further reduced to 5%, which equates to 25 g of sugars in a 2000 kCal/day diet.

With the aforementioned in mind, our Protein RTDs are sugar-free and thus typically well-suited for consumption by diabetics. Diabetics are, however, always advised to factor their nutritional supplement’s carbohydrate and sugar content into their daily diet plan and continue to regularly monitor their blood glucose levels to ensure that it is maintained within the recommended range.

Are these drinks vegan or vegetarian friendly?

Our Protein RTDs contain milk-derived whey protein and bovine collagen so are therefore unfortunately not suitable for vegans or vegetarians.

Are these drinks suitable for individuals with food allergies?

Our Protein RTDs products are formulated with ingredients free from allergens such as, soy, eggs, wheat (gluten), peanuts / tree nuts and seafood. However, they contain whey, so are therefore not suitable for those with a dairy allergy.

Can I drink Protein Ready-to-Drinks if I am on medication or have a medical condition?

Whilst our Protein RTDs are formulated with natural ingredients and are therefore not contraindicated with any medication, we always advise those with medical conditions or taking medication to seek advice from their medical practitioner before using any nutritional supplement.

Are these safe to drink during pregnancy or breastfeeding?

It is, however, always our recommendation for pregnant or lactating women to consult with their healthcare practitioner before embarking on any specific diet plan or using nutritional supplements to bolster their diets.

Premium protein and collagen. Zero preparation. Sport Rx ready-to-drink — no excuses.
