We are often asked “What is the best whey protein isolate?”
A seemingly simple question but the answer depends a lot on what your goals are.
Are you looking to avoid additives?
The most common additive is some form of lecithin which is added – around 0.5% – before the whey is dried. The resulting whey protein isolate is then described as ‘instantised’.
The most commonly used form of lecithin is soy lecithin although sunflower lecithin has also been used recently. Soy lecithin is rich source of the essential nutrient choline. Research has shown that supplementing with soy lecithin can be of benefit in acne, to improved liver function and in lowering cholesterol while increasing HDL (good cholesterol). However, some people are keen to avoid any form of soy so for them the best whey protein isolate will not contain any soy lecithin.
Other additives such as artificial sweeteners and flavours are probably not an issue for casual users of whey protein. If you’re one of those people for whom taste is the most important thing, then I guess, the best tasting is the best whey protein isolate! However, if you use a lot of protein powder often artificially flavoured and sweetened versions are probably not the best choice.
Natural or Raw Whey Protein Isolates.
Naturally flavoured and sweetened or raw (unflavored and unsweetened) whey proteins are probably better than those laden with artificial sweetners and flavours.
There is nothing wrong with natural flavours like vanilla and chocolate and natural sweeteners like stevia and xylitol are also well tolerated. We will be introducing some naturally flavoured and sweetened whey protein to our range soon.
At MyoPure we offer three different raw whey protein isolates, ACE WPI, MF WPI and US Premium WPI, and any of these might be the “best whey protein isolate” for you depending on what you’re looking for.
The Best Whey Protein Isolate
All whey protein isolates are made from wet whey protein concentrate and undergo additional processing to remove almost all the remaining fat and lactose (milk sugar) before drying. The different types of processes used to make whey protein impact the micro-fractions (large molecules that make up the whey protein) and amino acid content of the finished product.
USA Premium Whey Protein Isolate is made in the USA using a proprietary cross-flow micro filtration process gives the full spectrum of undenatured proteins found naturally in whey. It is instantised with around 0.5% soy lecithin. If you’re looking for value for money then USA Premium WPI is a great whey protein isolate for you.
MF Whey Protein Isolate is made in New Zealand using a different micro filtration technology that also gives a largely undenatured whey protein. If you’re looking a high quality whey protein isolate from pasture raised cows that mixes well without excessive foaming then MF Whey Protein Isolate is the best for you.
ACE Whey Protein Isolate is made in New Zealand using a sophisticated anion-cation exchange process that leaves the whey protein 99.6% undenatured. However, ACE WPI has 30% more branch chain amino acids (BCAAs) and 30% more cysteine/cystine than regular whey protein isolates. BCAAs are important for building and maintain muscle mass while cysteine/cystine is a precursor for the important immune system modulator, glutathione.
