 The Benefits of Protein Shakes

The best Protein Shakes are those with high bioavailability, meaning the protein comes from a quality source that the body can easily extract nutrients from to help build and repair muscle.

A whey Protein Shake tends to have the highest levels, with the rating of whey on the bioavailability scale being around 104. For reference, whole milk is around 91, casein is roughly 77, and soy is 74.  

When considering your own Protein Shake Recipes, high levels of protein and other essential nutrients are vital.  Protein Shakes that pack the most punch will be made from powders with complete protein mixed with foods like bananas, spinach and yogurt.


But, it’s not just the ingredients the determine the effectiveness of a Protein Shake. Timing is important, too.  In general, the best time to consume one is right after a workout. Why? Because this is when your body starts repairing muscle damaged during your session.

Protein is essential for building and maintaining mass and, without it, the body is unable to form the biochemical structures that are required for muscle repair, growth and healing. If you are doing a lot of activity that’s strenuous on your muscles, especially activities like weight training,, ensuring you heighten levels of protein accordingly is important.

It’s also important to recognise the fact that protein works with men’s and women’s bodies differently. But, that doesn’t mean either gender should skimp on their RDA.  There is often a misconception that if women consume too much protein, it will lead to unwanted weight gain. On the contrary, women can actually benefit from Protein Shakes, even if they want to lose weight.  That’s because protein doesn’t just help repair muscles. It also helps boost metabolism, curb cravings and keeps you feeling fuller, longer.
