Grass fed cold processed whey protein is one of the most easily digested and absorbed sources of proteins. It has an excellent amino acid profile (AA), including a very high ratio of essential amino acids (EAAs). Whey protein from grass fed cows is clean, anti-biotic and hormone free. When it is cold processed, the proteins are preserved so the whey retains all its potent health benefits.  See typical Amino acid profile last page. 



“As a registered dietitian I am always on the look out for ways to incorporate good quality protein into my clients diet’s, especially for breakfast. After trying Protelicious I have recommended it to many of my clients and use it regularly for family and myself. It is high quality whey protein that tastes great and is easy to incorporate into recipes and your favorite foods”.

Antioxidant and anti-inflammatory activity

With its exceptional richness in sulfur amino acids (cysteine, methionine), our grass fed whey will boost the synthesis of glutathione (GSH) which is the master antioxidant in the body and which regulates the oxidative status in all cells. It also regenerates other key antioxidants like vitamin E and C (brought from food) thanks to the glutathione reductase enzyme.

Upgrading our antioxidant reservoir, especially GSH is essential to fight against oxidative stress and chronic inflammation which together are a contributing factor to inflammatory diseases including ageing: cardiovascular (atherosclerosis), cancer, neurodegenerative diseases and others. Thanks to promoting GSH synthesis, whey will also boost our immune system as white blood cells (macrophages lymphocytes…) need GSH to operate effectively.



In addition, improving GSH content in cells is crucial for detoxifying the body from thousands of toxic and aggressive compounds such as aldehydes, pesticides, heavy metals, endocrine disruptors… Indeed GSH can be considered as the best scavenger of the body.  GSH has a natural affinity for binding these noxious molecules and the enzyme glutathione transferase increase it up to 600 times, ultimately promoting the elimination of these compounds into urine. In food, the sulfur AAs cysteine and methionine are rarely found in such high levels than in whey which makes these AAs the rate limiting substances of GSH synthesis.


Whey and immune system support

Whey proteins are rich in the sulfur containing amino acids cysteine and methionine. With a high concentration of these amino acids, immune function is enhanced through intracellular conversion to glutathione. Also glutamine, which is made from glutamic acid (whey is very rich in this AA) contributes to the health of intestinal mucosa and function,  which is key in immune system. The intestinal microbiome (intestinal flora) and its interaction is also very important and under studies at the moment.


Intestinal comfort

Whey is also rich in glutamic acid, an AA that can easily convert in glutamine. Glutamine greatly participates to the regeneration of intestinal cells and intestine health and digestion. Antioxidant like vitamin E and GSH also contribute to the good function and health of intestinal cells as well as protecting cells junctions thus avoiding or decreasing the passage of toxic and allergenic molecules.  The link between intestinal permeability and asthma and allergy has been described and is still under investigation and debate. Thus, whey can improve intestine function and digestive comfort and reduce inflammation and intestinal permeability which may help reduce allergies and asthma.


Regulates sugar and prevents cardiovascular diseases

Studies in human show that whey protein can be used in a medical/nutritional therapy to regulate blood sugar (hyperglycemia). It can also lower triglycerides, reduce blood pressure and the risk of hypertension and consolidate arterial health. Once again whey, especially in associations with certain vitamins, can greatly help the health of your heart.


Muscle recovery and synthesis

Whey can help maintain or increase your muscle mass, especially when paired with resistance training. This is well known by sportsmen and athletes, but it can benefit everybody! Indeed whey protein is one of the highest-quality proteins given its very high branched-chain amino acids content (BAAs: leucine, isoleucine and valine) and its rapid digestibility.  Actually it seems better than other proteins such as casein and soy to stimulate muscle protein synthesis.


Protects against sarcopenia

Whey is also more and more proposed as the protein source of choice to maintain muscle strength in the elderly who should consume 1.2 -1.5 g proteins/kg body weight/day. Indeed muscle loss is increased after 65 years as another consequence of the progressive loss of antioxidant potential, which promotes what scientists already call inflammaging. Whey (in association with antioxidants from fruits like the ones also present in our products) can significantly reverse this lost of muscle and improve inflammaging. It will also protect your bones.


Regulates body clock & sleep cycles & fight stress

Hormones are very important in the regulation of mood, stress as well as sleep quality. Among them, serotonin has a central importance to regulate our body cycle and our mood when melatonin is necessary to find a renovator sleep. The EAA Tryptophan is an unavoidable key precursor of the formation of these 2 hormones and is less common than other AAs in food proteins.  Guess what? Whey also has a very high content in tryptophan AA in comparison to many sources of proteins.


Supports weight loss or gain

Whey is a perfect tool to manage weight loss or gain and with our flavors it will be agreeable. Indeed it reduces appetite and helps to loose kilos in combination with taking care of avoiding too much carbs (mainly added sugar) and too much fat mass (especially processed and fried).

For weight gain, whey will both induce muscle synthesis (with at least 1.5 g/protein/kg of body weight/day included in your diet) promoted by branched AAs and improve your lean mass (protein)/fat mass ratio with some physical activity. Clinical studies now also show that whey can be in of great help in pathologies associated with weight loss.
