Red 8 Whey Protein Powder contains instantised, low temperature, ultra-filtered whey protein concentrate. Choice of Vanilla, Chocolate or Unflavoured. Very popular.

  • Highest quality ultra filtered whey protein concentrate
  • Highest levels of intact protein fractions

Red 8 Whey Protein Powder contains low temperature un-denatured instantised whey protein concentrate (contains lecithin), nature identical flavours, stevia and talin. 

Protein is critical for building and maintaining bone, muscle and skin. Consuming protein following intensive exercise has been shown to promote muscle protein synthesis, inhibit protein breakdown and promote muscle glycogen restoration. This results in improved muscle adaptations and increased muscle strength and function1. Due to its rapid digestion, whey protein is most effective in stimulating muscle protein synthesis during post-exercise recovery1-3.

Whether a weekend warrior or a serious athlete, good nutritional strategies are vitally important. In particular recovery strategies ensure that training gains are optimised and that subsequent training sessions can be performed effectively. Intense exercise results in increased protein breakdown and reduced protein synthesis. Consuming protein post exercise results in a reversal of these processes, and leads to increased muscle strength. For muscle growth to occur muscle synthesis rates must exceed muscle protein breakdown rates1-3.

The specific amino acid composition of Red8 whey protein assists in stimulating muscle protein synthesis. Red8 whey protein is a rich source of branch chain amino acids (BCAAÕs) and has been formulated to allow for rapid digestion and absorption which allows essential amino acids to reach damaged muscles faster. Net protein balance will remain negative in the absence of food intake. Consuming whey protein following exercise increases the availability of BCAAÕs and enhances muscle regeneration1-3.

Whey protein is suitable for use in a wide range of sports. Strength and power athletes have greater protein requirements than endurance athletes and athletes of all types have a greater requirement than sedentary individuals2.

Bit on the sweet side Review by
  • star

For me this product was far too sweet
And quite an artificial sweetness
I tried with both milk and water mixes
The way I like it best is mixed with a vanilla powder I have
So for me it’s hard to tell how good the protein is. The sweetness puts me off it and not a real chocolate flavor due to that factor

Great taste - creamy texture Review by
  • star

Was given a complementary sachet to try by Health post: liked the chocolate flavour - mixed up well.Good additional tool in your healthy diet & exercise kete.

Awesome Product Review by
  • star

I had started making my protein shakes with milk, unfortunately this gave me severe constipation so changed to mixing with water which sorted things! . Love the taste of the chocolate and will continue to use this powder.

Great apart from sweet aftertaste Review by
  • star

I tend to make my protein shakes just straight up with water and found this one had a distinct stevia aftertaste - almost too sweet for me. Mixed with other things it wasn't so noticeable. Otherwise a great protein powder.

Great taste, easy to use and affordable! Review by
  • star

I purchased this Red8 Whey Protein in the Vanilla flavour, for my partner who is currently training everyday for his Black belt in a martial arts. He really likes it! He comes home from training and makes it up with milk, a banana and adds some magnesium powder. Fantastic for muscle recovery after a hard workout and nice and light on the stomach. And it tastes great too!!! Will definitely be purchasing again!

Great value in all respects...... Review by
  • star

I find this an excellent product, great for a ' top up ' if busy, but it's versatile which includes baking. I now have
family using this product too.

Sweet Review by
  • star

Much sweeter than others. It mixes extremely well, as the powder is quite fine.

Disappointing Review by
  • star

I was given a free sachet of this with my last HealthPost order which I had with filtered water and ice in a Nutribullet. Unfortunately it was not good - thin and watery and the whey would not blend - kept settling out on the bottom even after a couple more good blendings. I accept it might be OK as an addition to a smoothie but it certainly doesn't cut it on it's own and without wanting to sound churlish my immediate thought was "I can see why they are giving it away!".

Love this product. Ticks all the boxes for me. Healthpost deliverys are exceptionally fast and their staff always helpful Review by
  • star

Love this product. Tend to use vanilla and add other fruits and avocado to my smoothies. Healthpost deliveries are exceptionally fast and their staff always helpful.

great versatile protein! Review by
  • star

I really rate this pure whey protein powder. You can use it in smoothies to add a protein kick, in baking, add to cereals and even salad dressings. All natural with no additives so I feel confident giving it to my young sons to make a super fluffy smoothie!
