Whey protein is confusing!

[Tino D'Voe]

The problem is that one store tells you something, then another says something different. I've been using Isolate for a while now, but lately getting sick of swallowing the nasty shit. I went to a new place today and the guy was recommending not to spend the extra money on the isolate, but to just buy some stuff called Syntrax Matrix. He also told me some stuff about how isolate can cause insulin spikes, and are digested too quickly. I ended up going for the matrix, just the taste alone sold me on the stuff.

Now I'm worried about it messing with my cutting diet that i've been doing quite well with lately. I'd like to hear some opinions on this, and I'm wondering if the regular whey should be used after workouts, and to stick with the isolate for morning cardio?

Any ideas?

That is fine.

Don't get too scientific about it. The main point is that you get some protein and carbs in you.

A generalised view of the protein scale looks as follows:

- whey protein isolate
- whey protein concentrate
- eggs
- milk protein
- meat protein
- casein protein
- soy protein

The product 'Syntrax: Matrix 5.0' is a whey concentrate based protein so you can see where it fits in on the scale. As a concentrate, it is a mix of casein, egg albumin, and milk solids. It is not the best you can use for mass building but it is suitable. Isolate is more suited for pre and post workout due to its quicker rate of absorption while casein and to a lesser extent concentrate is suited for use throughout the day. If you want to use isolate throughout the day, mix it with milk to slow the absorption rate. Just remember that it is more expensive per serving.

Matrix contains 2 grams of carbs per serving [110 calories total] so I wouldn't be overly concerned about it affecting your cutting phase assuming that your nutritional intake is already high protein, low carb based.

When purchasing supplements, spend more time reading the labels rather than listening to what the salespeople are telling you. I have seen too many people walk out of a health food store with something entirely different to what they had just been told.

good breakdown. The one thing that the salesperson mentioned is the way that isolate makes you feel hungry quicker than taking concentrate. If this is true, I definately want to find a way to stop the hunger cravings. I'm good at eating when I'm supposed to, I just have too much food cravings throughout the day.

I would advise using a casein based protein supplement as it has a much slower absorption rate and will help you get over your cravings. Although, you really shouldn't be having cravings if your nutritional intake is balanced. Perhaps pick one of your meals and split it up into two smaller portions and see if that helps you through the day.

Again, read the labels and watch the carb and fat content on the casein products as some are high.

The boire study found much of whey protein consumed on an empty stomach is converted to glucose. Milk protein is a better general use protein and whey is best used post workout. Based on the PCDAAS, most recent and widely accepted standard for humans, all egg and dairy sources of protein are equal. They all score a perfect 1.0. Meats receive between .8-.92 followed by soy and other vegetable sources bringing up the rear. A score higher than 1.0 is impossible under the pcdaas, a protein either has all of the EAA's in the appropriate amounts or it doesn't.
