The results of over 10 clinical trials demonstrate that soy foods and soy isoflavones have little or no effect on thryoid function in healthy adults. However, it has been discovered that individuals taking synthetic thyroid hormone medication may require about a 25% higher dosage of medication if they consume soy foods. Researchers have suggested that the increase in this medication requirement is due to an increase in the medication being excreted in the stool and/or a reduction in medication absorption—not due to a direct effect on the function of the thyroid.
Honestly, either is going to help boost your protein, both are safe and it comes down to personal choice.
Just be sure to know the nutritionals, so you can track and record accurately
Whey protein comes from Milk Soy protein comes from soybeans
So if you have an allergy to one of these foods---that should influence your choice. Some women undergoing breast cancer treatment may have to follow more strict intake guidelines regarding soy. Other than that---it comes down to personal choice. Like I already said: "both are safe"
most soy is gmo.... it screw with your hormones and can lead to estrogen dominant breast cancer... I go for organic whey protein... chocolate... love it.. the cocoa has extra flavanoids and hardly extra calories

If the whey was whey isolate then I would go for that. I am not a huge fan of consuming soy on a regular basis. Also check on their website to see what the calorie difference is.
Weight loss is primarily determined by calories out vs. calories in, so take a look at your overall calorie consumption along with macronutrients, such as protein.

I love drinking Jamba Juice all fruit smoothies, but I have been lacking a bit of protein in my diet, so I thought maybe adding a boost of protein in the smoothies would be a good way to get that extra bit. However, they offer two options: soy and whey. I don't know what the difference is between them or which one I should choose. I am currently trying to lose weight, if that has any influence on which to choose. Any suggestions would be helpful!
