I've been taking Isopure for quite sometime now but then saw "6 star" protein supplment at walmart for 14 bucks. This is about half of the price of Isopure. Can someone tell me the difference between the cheaper brands vs the expensive brands? The only real difference I could see from looking at the labels is the cheaper brand has abit less vitamins. They are both "whey" protein... is that all that matters? Thanks. |
From what I remember in science, there can be different combinations of amino acids, different concentrations that make the varying whey proteins absorb better than others... If that holds true, I'd imagine walmart brand will use the cheapest method to get their final product, regardless of the absorption process... And from my own research, when taking any protein supplement after working out to help combat nitrogen build up and give you muscles something to feed on instead of themselves, do your best to kick start insulin release in your blood to allow those cells to "open up" and absorb that protein with greater ease... This can usually be done by spiking your insulin with 100% grape juice, a cheap maltodextrin mix, or last resort, eating sweet tarts right after you do your cool down on the treadmill... |

Thanks for the response chromeluv, anyone else have any feedback? Also, I forgot to mention this in the original quesiton... Is it true your body can only digest a certain amount of protein per sitting? I've heard 40-50 grams is about the max? If true, how long should you wait after having your protein shake to eat your meal so that your body can absorb the protein from the shake and your meal? |
That's a myth. A 6'2", 210lb man with 8% body fat can only digest the same 50-50g of protein that a 5'9", 165lb man with 15% bf can? This number seems to revolve around what the serving size is on the latest supplement... Many many factors contribute to how your body metabolizes nutrients, and it can take a LOT at once. There is no magic number. Just treat your shakes like a meal. Throw in a cup of oats if you'd like; actually make it constitute a meal. |

The stuff at wal-mart is probably concentrate. I cant drink that stuff, it makes me bloated and is hard to digest. I take VP2 Isolate Read here about the differnece between concentrate and isolate. |
Casien protein is a slow absorbing form of protein. I prefer cottage cheese. |
