Soy protein isolate

use anything but soy

What's the best alternative?

pea protein is popular this time of year

I'll check it out, thanks

Soy is bad, soy protein isolate is fine. It has the exact same US Food and Drug Administration Protein Digestibility Corrected Amino Acid Score score as whey (both perfect). Do you doubt the USFDAPDCAAS?

>lactose intolerance
As I'm sure you know, lactose is a sugar, not a protein, so there's no reason to lactose to be present in a whey protein supplement. You might do some searching on message boards for other anti-lactites who've found whey brands that do a good job of getting the lactose out of their whey.

Due to the aforementioned ethanol (alcohol) extraction[12], the protein supplements tend to have very low isoflavone content (as the isoflavones remain in the alcohol solution). Typically around 0.05mg/g or 4% of the initial value of the soybean.[11][13][14]

For men worried about isoflavone content and possible estrogenic side effects, soy protein concentrate is the option to seek. Caution should be taken to ensure that the selected brand of soy protein concentrate has been heat treated to eliminate trypsin inhibitors, as they may still be active.

Just like there's no reason for lactose to be in a whey protein supplement, there's no reason for phytoestrogens to be in a soy protein supplement.

This process does not undergo further ethanol extraction, and thus still has isoflavone content. Due to the first hexane extraction where oil was removed from the soybean (prior to the formation of 'white flakes'), the Soy Protein Isolate does not have 100% of the isoflavone content of soybeans, but around 38-46% (or 0.5-0.6mg/g).[11][1]

oh yeah? well:

A 2010 meta-analysis of fifteen placebo-controlled studies said that "neither soy foods nor isoflavone supplements alter measures of bioavailable testosterone concentrations in men."[34] Furthermore, isoflavone supplementation has no effect on sperm concentration, count or motility, and it leads to no observable changes in testicular or ejaculate volume.[35][36]!

No seriously I was no aware of that. Interesting.

It doesn't lower testosterone; it binds to and activates estrogen receptors.

You can go for whey isolate though, the lactose content is not enough for you to notice, some sites say that it's less than 1%.
