I always like to keep an ear open to new things, especially where my health and fitness are concerned. And something I’ve been reading about recently is a slow-digesting protein called Casein. Somewhat comparable to whey protein, Casein is absorbed and used by the muscles at a different. According to an article I found on Men’s Health, casein is a slow-acting form of protein that “drip feeds your muscles” and “your blood amino acid ‘peaks’ with your protein synthesis […] and continues to do so for up to four hours after ingesting.”
So, what’s the skinny? Is this shit better than whey protein? From what I’ve read, they’re both quite similar with the exception that whey is absorbed much faster. The slower rate at which the body processes Casein makes it a bit easier on the body as it provides a steady stream of amino acids and protein to the body instead of having get all soaked up in one shot. That same Men’s Health article goes on to explain that Casein is usually best taken before bed, since its slow delivery allows for better muscle recovery while you sleep.
Another article I found posted on Muscle & Fitness also agrees that whey is the best option as a post-workout protein, but lists a number of benefits to including Casein in your fitness regiment. Besides lasting longer than whey and helping to provide greater strength, the article boasts greater muscle gains and some fat loss benefits. Of course, like everything else, this is combination to a good diet and consistent exercise.
One last benefit that Muscle & Fitness included is that the consumption of Casein can potentially reduce and prevent the effects of enamel erosion. That’s based on some studies from the UK, of course. So one needs to take it with grain of salt. But it would be cool if it did since you don’t usually hear about fitness supplements providing such a benefit.
Last but not least of course, is the fact that there are some studies showing that Casein can help with insulin and glucose levels. But I wasn’t able to find anything definitive. At least, nothing worth mentioning here. But I intend to keep researching and looking into it and I’ll be sure to add to this if there’s a positive Diabetic component that’s found.
In the meantime, I’ll say the same thing I say with everything else. Although this is an over-the-counter supplement, you should consult your medical practitioner before adding any specialized supplements to your daily diet. Like everything else, Casein may not be for everybody and since everyone is different, all the benefits listed in these articles may not necessarily work for you. ☯
