Dairy milk contains two major protein components, casein, and whey. Whey makes up only 20% on average of the total protein and is much more readily absorbed as a protein source than its counterpart. Whey is a complete protein source, which means it contains all nine essential amino acids (the building blocks of protein which the body cannot produce on its own).

There have been countless studies on the effects of dietary supplementation with whey, yet I’ve found that patients are often wary of using this supplement because of dairy sensitivities. Whey of course is not dairy free, however it contains little to no lactose, the sugar most frequently associated with indigestion of dairy products.

Below are 5 evidence-based benefits found with supplementation of whey protein, and the driving factors why it frequently ends up on my list of suggested supplements.

Lowers blood pressure

“Whey protein significantly decreased systolic blood pressure in pre‐ and mildly hypertensive adults, who are also overweight and obese”.1 Whey protein contains naturally occurring ACE inhibiting enzymes. This is the goal of many commonly prescribed pharmaceuticals aimed at lowering blood pressure.

Improves Blood Sugar

Studies have shown whey protein ingestion significantly lowers HbA1c and fasting insulin.5 “Whey protein stimulates GLP-1 and GIP release”2 ,mimicking the target of prescription drugs used in diabetic patients. This leads to improved blood sugar control and may also help with weight loss.

Reduced Inflammation

Whey protein contributes to increased glutathione production, which helps decrease oxidative stress in the body. We have found whey protein supplementation decreases hsCRP and more rapidly improves on mental status tests in recently hospitalized ischemic stroke patients. 3

Cardiovascular Protection

A recent study has found that those consuming whey protein had improved endothelial function4. The endothelium, or the inside lining of your blood vessels, is critical for proper blood pressure maintenance and prevention of plaque deposit in the arteries.

Improve Blood Lipids

Researchers have observed significant reductions in triglycerides, total cholesterol and LDL cholesterol in whey protein patients5 of a meta-analysis which reviewed the data for whey protein supplementation on improving cholesterol panels.

Leave the Rest, Get the best

Not all whey protein is created equal.

New Zealand grass-fed cows are of the best quality in the world. We source only the purest ingredients to recommend our patients and therefore use cold pressed, hormone free, gluten-free, 100% New Zealand grass fed whey protein in our functional nutrition powder, Daily Defense.

Not only is this the best tasting protein on the market, but is truly an all-in-one nutritional supplement you can feel good about. Daily Defense provides you with the best macronutrients and micronutrients PLUS enzymes and probiotics to ensure that you will properly digest and not feel bloated, as with many protein powders.
