There are many different types of protein powders on the market today. The 4 major types will be outlined below to help you find the powder that is right for you, your body type and your fitness goals.
This is the most commonly used protein powder supplement. This protein is very inexpensive and most protein powders rely on whey protein in whole or in part more than 50% of the time. Whey protein is a portion of milk protein. It is easily mixed with liquid.
The main benefit of this type of protein powder is that it is digested very quickly. This rapid digestion turns your metabolism and body into an anabolic state instead of being in a catabolic state (breaking down muscles mass for energy).
Whey protein is great for the morning first thing to quickly get your body back into an anabolic state. The second best time to supplement with this is directly after a workout to replenish those much needed nutrients and amino acids.
Casein is a much slower digesting form of protein. Since it takes a lot longer to digest, it makes for a perfect meal replacement shake. This protein will give you a slow and steady release of amino acids which in turn protects your body from muscle catabolism.
The best time to take a Casein Protein Shake is at night before bedtime, which is the longest time you will go without a meal. This will again prevent muscle catabolism or breakdown throughout the night until morning.
Very comparable to Whey Protein. Soy Protein has been shown to enhance Thyroid Hormone output (which increases metabolism) and the isoflavones have cholesterol and triglyceride lowering effects.
One fallback is that soy isolates are broken down more readily in the liver versus milk proteins. This in turn means there will be fewer amino acids available for your muscles.
Egg protein is a very high quality protein source. It is very low in Fat and in Carbohydrates which makes Egg Protein a better choice for a diet. It also has a solid amino acid profile high in sulfur containing amino acids which aid in producing natural hormones.
Look for it to be labeled as Egg Protein, Egg White Protein, Egg White Solids and Egg White Albumin.
Other powders will often contain extras such as creatine, glutamine, nitric oxide boosters and many more. They still fall into one of the four categories above.
While there are many different types of protein powders available this information should aid you in making the right choice for your fitness goals.
