FAQ for Protein
Can I mix my protein shakes ahead of time?
The concern with mixing protein shakes ahead of time is spoiling. Make sure you are able to store them in a fridge till you are ready. Mixing your protein powder ahead of time will not lose any of its amino power or vitamins and minerals. One thing you can do is premix the protein powder in a ziplock bag and then add it to water when you are ready.
Do I need a protein shake if I am using a post recovery shake?
You don’t need an extra protein shake. Your post recovery shake should have protein in it. If it doesn’t then adding a protein shake is a good idea. If you post workout shake doesn’t have protein in it I would change to one that does.
How long can my protein sit in my cupboard?
Your protein powder should be good for on average about two years from when it was manufactured. Your protein powder won’t necessarily go bad if kept in a cool and dry place; though the amino acids, vitamins, and minerals can start lose their effectiveness.
What are concetrates, hydrolysates, and isolates?
These terms relate to the processing methods for creating the protein powders. Concentrates have on average 80% of the non protein compounds removed to make a more pure protein source. Some cheaper protein concentrates do have less than 80%. Isolates take even more non protein substances out creating around 90% pure protein source. Protein isolates as they are higher quality protein sources typically cost more than concentrates.
Hydrolysates are pre digested proteins into smaller pieces that are absorbed even faster. Hydrolysates and isolates have performance benefits over concentrates as your muscles get more high quality protein.
What does fast, medium, and slow acting proteins mean?
This relates to the rate at which the protein source is broken down in your digestive system and enters the blood stream to be transported to your muscle tissue. Whey is the fastest followed by egg. Casein is the slowest and recommended as the protein source before bed.
What is a biological value for protein?
A biological value (BV) is a score used to show the digestibility of different protein sources. Protein digestibility corrected amino acid score is another method used. The higher score means that more of the protein source is able to be broken down and utilized by the body. Whey and egg proteins rank the highest with casein and soy have lower scores.
Can you eat too much protein?
The answer is yes. On average with the low carb craze, many Americans are getting too much protein. Too much protein gets stored as fat just like too much of anything. Also, if you are having not so pleasant bathroom visits going #2 it is probably because the protein powder you are using isn’t being absorbed by your body. This is typical with cheaper protein options.
