Get the Most From Your Protein

Every protein source has a biological value (BV). The BV of a protein source indicates how fully the body absorbs and utilizes the protein. The higher the value is, the more completely the protein consumed will be absorbed and used by the body. The chart below gives the BV of common protein sources*.

*Values are approximate and do not represent BV measured in humans at levels of protein intake

Find the Protein that's Right for You

For most active people, getting enough protein solely from food sources each day can be very challenging – making the phrase “eating all day” more than just a cliché! So getting supplemental protein in the form of protein shakes, drinks, bars and supplements is a real plus for many active people. Using Weider protein supplements is a great way to get all the protein your body needs, but without increasing your intake of saturated fats, cholesterol and other undesirable ingredients often found in many high-protein foods.

Not all protein sources are created equal however - they all have their own strengths and weaknesses and by finding the right combination for your goals and lifestyle, you'll be able to achieve the results you really want!
