There is no doubt that taking whey protein supplements can help you if you are doing resistance training. It is probably the best way to deliver necessary protein to the body in order to rebuild muscles after an intense workout. Some people might shy away from using these supplements for a number of different reasons. First of all they might not be aware of all of the benefits and secondly they may be concerned about the price.
If you shop around for whey protein supplements, you may find that they come in a number of different sizes. Most companies will offer anything from 1 kg up to 5 kg packaging and you'll notice that the price is not proportionate. If you find a product that you like, then you can save a lot of money if you buy in bulk.
Protein Powder Whey
It might not be wise to buy bulk whey protein right from the start. First of all, different supplements taste different and you may have trouble getting some of them down if you're not used to it. Don't be concerned, most of the time they actually taste pretty good. If you buy one then find that you don't like it, you may want to go with a flavoured version. Many companies offer both flavoured and unflavoured varieties and once you find one that you like, you can buy bulk whey protein in the flavoured varieties as well.
There are also different kinds of whey protein. You'll see products advertised that are called concentrate. There are others called isolate. The concentrate version is a little cheaper and it is a little less refined than the isolate. There's nothing wrong with it, in fact it is suitable for use by most people. It will have a little bit more of the fat and lactose that is present in the whey and it will have more of the protein.
If you are very serious about developing lean muscle mass and you are going to be using intense workouts then isolate might be better for you. You will find that it is more expensive and this might be a good reason for you to purchase bulk whey protein in isolate form.
One of the great things about using whey protein as a supplement is that it has a very long shelf life. You don't have to be too concerned about buying a 5 kg package and having it go bad on you. If you continue with your resistance training regimen and you are taking this supplement on a regular basis you'll have no trouble finishing it long before it expires.
If you were to store it in a cool, dry place then you really won't have to worry about it. If you end up with supplements that are passed their expiry date, then the only likely result is that they are slightly less effective. In almost every instance, buying in bulk will be a much better investment.
