Some vegans have no problem with soy, while others choose to stay away from it for several reasons. And in today’s world, we’re spoiled for choice in the variety of products we can use for supplementing protein to build muscle. Fortunately, vegans who wish to avoid soy have plenty of vegan protein powder options without soy and come from some of the best available plant-based protein sources.

soy free protein sources

I’m going to be completely honest with you, I do drink soy milk in moderation, but I don’t drink it all of the time. And I don’t consume soy protein powders either. I think many people would agree that moderation is the key to anything in life, including where you get your protein from.

So with that out of the way, I did a bit of research to help you decide on a good vegan protein powder without soy.

Before I go into the best soy-free protein powders, I’ll list a few reasons why experts in nutrition believe we should avoid soy foods in general.

Reasons to avoid Soy

  • Soy foods contain natural toxins or antinutrients and are potent enzyme inhibitors
  • Many soy products you find are genetically modified
  • Soybeans contain something called phytic acid which blocks the absorption of key minerals that the body needs to remain healthy
  • Soy contains phytoestrogens which may upset hormone balance by lowering testosterone and increasing estrogen levels
  • There is some evidence that soy isoflavones have goitrogenic effects and interferes with thyroid function
  • Soy can increase IGF-1 level compared to other plant-based protein sources, and this may increase the risk of cancer in the long-term
  • Contains hemagglutinin  which causes red blood cells to clump together
  • Soy may have high levels of aluminum and manganese (for the latter, many plant diets get too much of).
  • People with soy allergies

There are many other reasons that people choose to avoid soy besides these, but these are some of the main ones.

The controversy around Soy

You mention the idea of consuming soy for some people and they’ll give you a long list of reasons why it should be avoided. While some of them may be valid, some of them are also over-simplified or exaggerated.

That’s not to say there aren’t good reasons to at least *limit* your intake of soy and opt for protein powders which don’t include any soy at all.

Moderate amounts of soy should not pose any harm to adults, but perhaps the jury is still out on whether or not there are any long-term implications. Fortunately, these days there are so many options for us vegans to get good high-quality protein powders which are soy-free.
