Our hydrolyzed liquid protein has been broken down into its simplest form of amino acids, making it easily absorbed for the body. Its liquid form makes it ideal for morning use, afternoons, or right before bed. Its small presentation makes it ideal for on the go. Store in your bag, purse, side table or carry on. It’s convenient and efficient to use while traveling. Protein on the go is this simple.


If you have diabetes or pre-diabetes, your doctor or dietician will likely recommend a healthy-eating plan that will help you control your blood sugar (glucose), manage your weight and control heart disease risk factors, such as high blood pressure and high blood fats. Sine Proteinex has no sugar or fat, it is acceptable to most diabetic patients. It’s a high dose protein that’s also great tasting without the addition of any sugar.


In many instances, bariatric patients will follow a liquid diet leading up to surgery. The purpose of this diet is to reduce fat around the liver, allowing the surgeon to see and navigate the anatomy seamlessly. A typical pre-op diet is high in protein and low in fats and carbohydrates. Following surgery, diet is important as the stomach needs to heal, and a good diet will prevent it from stretching and putting stress on the body. Since Proteinex is high in protein, and contains no fat, no carbs, and no sugar, it is the ideal nutrition to be included in pre and post surgery liquid diets.   


Recovery is an important component of any surgery, treatment, or illness. Recovery is also essential for when we have wounds, cuts, and burns that need to treat and heal. Protein allows us to heal faster since it contains all essential and non essential amino acids. It also helps maintain us strong and properly nourished for any subsequent treatment that may follow.   


Out of the 20 different amino acids, nine (indispensable) must be supplied by dietary intake. These are Histidine, Leucine, Isoleucine, Lysine, Methionine, Phenylalanine, Threonine, Tryptophan and Valine. All Proteinex® products contain all the indispensable amino acids as well as the dispensable amino acids. When the human body is injured, it will utilize these amino acids for healing. But if one or more of the indispensable amino acids is missing due to poor diet then the repair cannot be made and further breakdown of the body will likely follow.   


Arginine studies have shown that it improves immune responses to bacteria, viruses and tumor cells. It has also been found to promote wound healing and aids in regeneration of the liver. Found in large quantity in blood hemoglobin, histidine it has been used in the treatment of rheumatoid arthritis, allergic diseases, ulcers and anemia. A deficiency of Histidine can result in a hearing deficit. Lysine ensures the adequate absorption of calcium, helps form collagen, aids in antibody, hormone and enzyme production. A lysine deficiency may result in tiredness, lack of focus, irritability, slow growth, hair loss or anemia.  


As collagen in your body deteriorates as you age, bone mass does too. This may lead to conditions such as osteoporosis, which is characterized by low bone density and linked with a higher risk of bone fractures. Consuming collagen protein supplements may help reduce the risk of bone disorders such as osteoporosis. They have the potential to help increase BMD and lower levels of proteins in the blood that stimulate bone breakdown.


Achy and stiff joints can limit our day-to-day, reducing our mobility and overall strength. Whether your joint pain is a result of a health condition, sports related injury, or the normal wear and tear, protein derived from collagen has been proven to reduce pain, decrease stiffness, and reduce loss of joint range of motion.
