Why Take?

Getting the correct nutrition through food prep can be difficult and is time consuming. This is where a product of this nature fully serves its purpose. A Pro Whey Recovery shake can be prepared in less than 2 minutes and provides the carbs and protein your body needs to recover to its best capacity. The most important aspect of any product is its ingredients and the purpose they serve. Our team of expert nutritionists have created a complete performance and recovery formula.

Grass Fed Whey Protein The Whey we source is derived from milk, which gives it a superior amino acid profile in comparison to whey derived from cheese. You get 14% more of the muscle building amino acid L-leucine from milk whey. Grass fed whey is considered to have a superior nutrient profile in comparison to grain fed whey. Grass fed whey has increased levels of omega 3 essential fatty acid, Vitamin E and conjugated linoleic acid.

Ultra-fine Gluten Free Oats Protein is considered the most essential nutrient for muscle building. However, carbohydrates play a key role. Carbohydrate intake is crucial for optimal muscle recovery. Our blend of complex and simple carbohydrates provides the perfect ratio’s muscles need for recovery. Gluten free oats are complex carbs which slowly digest and release the sugars to help replenish muscle glycogen stores, which facilitate muscle recovery and growth.

Gluten Free Oat Flour

Gluten free oats are complex carbs which slowly digest and release the sugars to help replenish muscle glycogen stores, which facilitate muscle recovery and growth.

Native Grass-Fed Whey Protein Concentrate

Grass-fed whey comes from grass-fed cows. These animals are raised on organic pastures and eat natural, plant-based diets — not the corn or soy diets filling the troughs of conventional farms. Because of this, grass-fed whey protein has higher levels of immune-boosting, bioactive compounds. Research showed that grass-fed dairy consists of higher levels of Omega 3 fatty acids and lower Omega-6: Omega-3 Fatty acids resulting in a more favourable ratio. While omega-6 is pro-inflammatory, omega-3 is known for its anti-inflammatory properties.

L Glutamine

Supporting muscle recovery and digestive and immune systems

Grey Sea Salt

Salt is an essential electrolyte that is lost through physical excursion. It is added to support sodium balance within the body throughout the toughest workouts. Balance of the cellular sodium potassium pump is essential to maintaining performance levels and avoid cramping and fatigue.

Maltodextrin

Maltodextrin is a simple carbohydrate which releases directly into the blood stream, stimulating a spike of Insulin levels. This hormone is beneficial for muscle building as it has an anabolic mechanism and helps shuttle amino acids into muscle cells, where they are used for muscle repair and growth.

Sucralose

Sucralose is 600 times as sweet as sugar. This means only a very small amount is required to sweeten products and therefore doesn't affect the purity of the protein powder. Studies show sucralose may help lower body weight compared to sugar and other artificial sweeteners.

Cacao powder (chocolate flavours only)

Cacao powder is made from raw cacao beans and nibs that are fermented, roasted, and milled into a powder. It's similar to cocoa powder, but it's more nutritious because it's less processed. Eating it in moderation could help improve your brain function and lower your cholesterol.

Madagascan Vanilla Powder (Vanilla Flavours Only)

It has active compounds that stimulate the production of serotonin, also known as the happy hormone. It can help improve mood, reduce anxiety and promote a feeling of well-being. Studies have shown that the scent of vanilla can reduce anxiety, calm the nerves and promote relaxation.

Freeze Dried Strawberry Powder (Strawberry Flavours only)

Added to Wild Berry protein. Strawberry powder adds a natural fruity strawberry taste to the wild berry protein. Strawberries are abundant in nutrients to support performance and recovery. It is a quality carbohydrate to help replenish glycogen stores after intense exercise. Strawberries are rich in vitamins minerals and antioxidants to help recovery of muscle cells damaged by training
