  • Recovery support

  • Low in fat & carbohydrates

Consuming sufficient amounts of high quality protein on a daily basis is essential to help maximise muscle protein synthesis.

This highest biological value protein supplies the optimal balance of essential and non-essential amino acids to support muscle growth and strength.

The l-glutamine and BCAAs naturally occurring in WHEY Rx help to maintain cell hydration and volume, decrease protein breakdown and muscle damage, reduce soreness post-training and speed up recovery after hard sessions.

Whey protein has also been shown to increase levels of glutathione, one of the body’s most important antioxidants, as well as support the immune system, which is placed under stress during intense training.

There are less than 2 grams of carbohydrates and fat in every serving. WHEY Rx also contains no added sugars and is free from preservative, artificial flavours and colours.

This product falls under the premium SPORT Rx umbrella – South Africa's first clean label brand.

Who should use WHEY Rx?

WHEY Rx is a high biological value, pure whey protein formulation, developed to provide the highest quality of supplemental protein possible to those engaged in weight training and other physically strenuous sports, as well as those who are looking to optimise their muscle recovery and lean muscle building efforts. Consumed after gym or intense training, WHEY Rx provides all the essential and non-essential amino acids as well as bioactive peptides needed to fuel muscle recovery and growth.

What does WHEY Rx taste like?

Each blend has a unique taste as they all contain different flavouring ingredients, from cocoa to vanilla caramel. There is no grainy texture, and we do not add artificial flavourings or sweeteners to any of our blends. WHEY Rx is often praised by clients for its great taste!

How can I store this product?

WHEY Rx should be stored in a cool, dry place like your pantry, although storing opened packaging in your fridge may help to prevent moisture absorption and clumping, especially in warm, humid environments, thereby potentially extending shelf life.

Is WHEY Rx safe for children?

Yes, absolutely! WHEY Rx is a dairy-based food formulation, combining high quality, milk-derived whey proteins (concentrate, isolate and hydrolysate) with a delicious flavouring system that is free from pharmaceutically active ingredients, or potentially harmful chemical ingredients. As highly active, sporting teens may not eat a sufficiently varied and nutritious diet, nor consume sufficient high quality proteins and amino acids to meet their body's recovery demands, WHEY Rx can offer valuable nutritional support to help them recover and perform at their best.

Is WHEY Rx diabetic friendly?

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, WHEY Rx is low in sugar, containing less than 2 g per serving 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 your products safe to use during pregnancy or breastfeeding?

While WHEY Rx is formulated entirely from natural ingredients that one would typically find in nutritious everyday foods like yoghurt and milk, it is 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.

Is WHEY Rx gluten-free?

While WHEY Rx is made in a facility that uses tree nuts, peanuts, wheat (gluten) and eggs, the formula is free from gluten and can thus be considered gluten-free.

Is this product suitable for vegans and vegetarians?

Since WHEY Rx contains dairy-derived proteins (cow’s milk) it is thus suitable for those vegetarians following a lacto-vegetarian diet. It is not suitable for vegans.

How many servings of WHEY Rx can I consume per day?

Due to the natural composition of WHEY Rx's formulation and safe ingredient makeup, we believe that it is safe to consume multiple daily servings, as may be needed to achieve one’s daily protein requirements. That being said, we do not believe it to be typically necessary to consume more than 1 or 2 servings per day to derive the intended nutritional support. This product should furthermore be used as a protein supplement only in conjunction with a nutritious diet and not be relied on as a sole source of protein.

Does this product contain any fillers, binders, sugars or sweeteners?

All SPORT Rx blends are formulated to be 100% free from artificial ingredients including fillers, colourants, preservatives and artificial flavouring and sweeteners.

What are the benefits of WHEY Rx?

WHEY Rx supports muscle recovery and repair, lean muscle building and improved body composition. It promotes gains in muscle strength and fuels antioxidant and immune support.

Are SPORT Rx products safe for athletes?

Our blends use 100% natural ingredients which are safe for athletes and contain no artificial or prohibited substances.

When is the best time to take WHEY Rx

Whilst WHEY Rx is an ideal post-training protein supplement, consumed as soon as possible after exercise to kick-start the recovery and muscle-building process, it can also serve as a convenient on-the-go protein supplement suitable for consumption any time of the day, morning or night, to bolster your daily protein intake.

Will WHEY Rx make me gain muscular body weight

Whilst WHEY Rx may help you achieve your physique and fitness goals, whether you want to gain muscle or lose fat, supplementation needs to be combined with an effective training programme in order to provide the stress and stimulus needed to signal muscle growth. In the absence of these stimuli, protein supplements alone will contribute very little, if anything at all, to muscle gain.
