Health Conditions Discover Plan Connect. Basics Shelf life Health risks Bottom line Protein powders are an incredibly popular supplement among health-conscious people. Sometimes, a quick-digesting protein, such as whey, may pass too rapidly through the digestive system and into the intestines for the body to properly take advantage of all of the nutrients. Taking casein right before bedtime is ideal, as it provides a slow release of aminoacids, helping to prevent muscle breakdown and thus keeping your system more anticatabolic.
Written by Kim Oddo. Related Articles. It may also help with fat loss. Although more human studies are needed, initial research shows casein may improve aspects of health, such as lowering triglycerides and helping with weight loss. The myth that high protein intake causes ill health has been debunked many times. Direct studies and reviews have highlighted that there are no negative effects in healthy individuals.
The only exception is those with current kidney or liver disease, who may need to limit their protein intake 20 , 21 , If you take scoops of casein per day, then it is highly unlikely that you will get any noticeable side effects, let alone serious ones.
That being said, some people are allergic to casein or intolerant to lactose, which is often found in small amounts with the supplement. Other people may become bloated or experience other digestive symptoms, but this depends on the individual. Like whey, casein protein is very safe for human consumption.
As discussed above, it may even have some impressive long-term benefits for your health. Like most sources of protein, it is safe for regular consumption and may even provide long-term health benefits. One of the proteins in casein called beta-casein exists in several forms. Some observational research has started to link A1 beta-casein to health issues such as type 2 diabetes and heart disease 23 , 24 , However, observational research is far from conclusive and only highlights associations, which tend to be unreliable in nutrition.
Other studies on A1 beta-casein find no detrimental effects 26 , The research and debate on A1 and A2 beta-casein continues, but for now this is probably not something you need to worry about.
If you are concerned, then you can read more in this article here. Some observational studies show health issues from consuming A1 beta-casein, but the research is far from conclusive. If you are taking it before or after a workout, then it makes sense to use a faster-digesting form like casein hydrolysate — or you could simply take whey protein.
For example, you can eat scoops grams of casein protein powder mixed with water. You can simply put casein and water in a shaker bottle and mix it that way, or in a blender with some ice. You can also put it in a bowl and stir it with water until it gets a pudding-like consistency, then put it in the freezer for 5 minutes.
Then it tastes a little bit like ice cream or frosting, especially with flavor like chocolate or vanilla. That being said, you can also get plenty of casein from natural dairy products. Casein, a slow-release protein, may well do the trick. Below, we shake up your knowledge on one of the UK's most popular supplements and bring you a handful of recommendations to help you unlock new potential. Ready, steady, shake.
Casein is a slow-release protein that's found in milk and in cheese and forms one of two proteins found in these foods. Carrying the same amino acid profile as whey protein , casein protein is actually absorbed at a different rate. During the processing of milk , casein protein forms a jelly-like substance that, one formed into protein powder, becomes a slow-acting form of protein that drip-feeds your muscles. Whey protein , for example, feeds your muscles at a faster rate.
When you consume casein protein, your blood amino acid 'peaks' with your protein synthesis — the rate at which you absorb muscle-building protein — and continues to do so for up to four hours after ingesting. Casein protein and whey protein are very similar on the surface level, but are quite different a molecular level.
While both casein and whey are dairy-based proteins derived from milk, there are some glaring differences. Firstly, whey protein is considered the faster-acting supplement over casein. Rapidly digested, whey protein is found in the watery portion of milk, is a mixture of protein isolates and is considered a complete protein, housing each of the nine essential amino acids. Casein protein, on the other hand, is a slow-releasing protein. In other words, after ingestion, your muscles will be 'drip-fed' casein for up to four hours.
Casein protein is often considered to be 'anticatabolic' essentially, kinder on your muscles as it provides a steadier stream of acids and protein supply to stave off muscle breakdown going catabolic , while whey protein is rapidly digested by your body.
