We do use soy protein in some of our products, however, we are continually trying to expand our product/ingredient variety to provide for a wide range of personal preferences. Many of our products contain whey protein for those who personally choose to avoid soy.
Our food nutritionists and scientists believe strongly that soy protein is a great source of protein because it builds new cells, is easily digested in the body, and improves the taste of a lot of foods. We also believe the quality of the protein is one of the most important factors. This means it contains ample amounts of all essential amino acids, and in the right ratios. We only use the best quality protein, of all types we use.
We are aware some people are concerned that natural components in soy protein negatively affect health. However, clinical studies on humans have not shown these concerns to be valid. Additionally, the soy protein that we uses is nearly devoid of estrogenic activity. We do have instant coffee that is completely soy-free, our Vitamin Coffee is simply an arabica dark roast blended with nutrients. https://nutrientfoods.com/.../pro.../nutrient-vitamin-coffee
Soy protein contains naturally occurring components called isoflavones. More than 100 clinical studies show that isoflavones do not adversely affect male health (lower testosterone) or female health (increased risk of breast or Testosterone levels do not go down in men, and estrogen levels do not increase in women after consuming soy protein; here are just a few highly regarded articles regarding the safety of soy:

Soy is an excellent source of protein because it provides all 12 of the essential amino acids our bodies need daily. Our bodies can’t make essential amino acids, so they need to come from the foods we eat. Essential amino acids are the building blocks for the body to create the proteins it needs to make hormones and enzymes, as well as new cells for muscle, blood cells, brain tissue and many other crucial body functions. High-quality proteins are rich in essential amino acids and contain them in ideal ratios for use by our bodies. Soy protein and all animal proteins like those from milk are equal in quality.
