Peak Nutritionals - Premium formulated Sports Nutrition.

We stand by our products in bringing you premium sourced protein (agglomerated & instantised WPI derived from sweet dairy whey and manufactured by a special cross-flow filtration process) with the addition of some beneficial ingredients to compliment your performance, endurance & recovery with your sporting pursuits. This process leave us a superior nutritive value protein content with enhanced dispersibility properties. Our WPC in its pure form is sourced from the richest pasture fed cows in Australia and is derived from the utlra-filtration of whey sourced from Warrnambool Cheese and Butter's processes.

WPC and WPI protein powders will assist with the building of lean muscle. By using Peak Nutritionals™ protein powder and pacing your muscles through training or strenuous exercise, the after effects such as DOMS (delayed onset of muscle soreness) will be reduced as Peak Nutritionals™ products will nourish your muscles through recovery resulting in new lean muscle growth and the ability to get back to training quicker with less down time due to muscle over strain.

Whey proteins contain natural occurring branched chain amino acids to promote muscle protein synthesis meaning your muscles will recover faster after training, ensuring nutrients are transported for total muscle maintenance, improved strength and for endurance. The release of branched chain amino acids from the protein into the intestine and how this is absorbed into the bloodstream is based on whether you prefer a slow or faster release protein for results you require.

Our Whey Protein Concentrate in particular is an ultra-filtered premium grade powder with natural phospholipids for cell repair. It means you will have a more sustained release, maintain feeling fuller for longer and continued endurance to get through your workout with upto 90 minutes post training for best results.

Whey Protein Isolate is a protein powder that has been through the cross flow micro filtration to eliminate fats and sugars (carbohydrates) that results in a higher protein content as an end product. Due to this process the branched chain amino acids will be faster releasing in your body meaning it will be quickly absorbed and digested for upto 60 minutes pre or post training for optimal results.

Both our WPI and WPC are GMO-free, of low glycemic index & low in fat.

All of our Peak Nutritionals™ products contain digestive enzymes are very gentle on the stomach so you will easily absorb and digest the protein, fats and carbohydrates, meaning less opportunity for stomach discomfort or gas as a result that may sometimes occur when you ingest too much whey protein. The science behind the use of digestive enzymes is that as we age our bodies ability to effectively break down whey protein diminishes and nutrients may not be easily absorbed. By using the three different digestive enzymes ; Protease, Lactase and Lipase, specific for break down of whey protein, fats and carbohydrates, you will get the best nutrients your body needs to transport to all your vital organs to enable you to continue to the level of endurance and muscle support for your sporting regime.

Why is it that sports nutrition is not suitable for under 15 years of age?

The Food Standards code:- 'Due to the particular physiological demands of sports people, this Standard provides for the addition to formulated supplementary sports foods of certain micronutrients and other ingredients which are not permitted to be added to other foods. This means that such products are not suitable for consumption by children'.

It has to do with body weight and the need for protein. For adults you need 1 gram of protein per kg of body weight and a supplement should supply no more than 50% of the RDI. For serious sports people this is increased to 2 grams per kg of body weight.

For children the recommended intakes are:-

4-9 years 19 gram

9-13 years 34 gram

14-18 years 46-52 grams

For example, a 70kg adult requires 70gm of protein (35g max from a supplement)

A 70kg serious athlete requires 140 gram of protein (70g max from a supplement)

Children do not require any protein supplement above a normal healthy diet including three serves of dairy per day.
