Why did I stop using this protein shake? Well, I did some research and although the shake does have many healthy ingredients and helps you to control your cravings, I found that the first ingredient listed, Soy Protein Isolate, is not necessary, and can be unhealthy to have, at such a high dosage.
I think this 'not necessary' is the problem here. While a small amount of natural soy protein is healthy (edamame, tofu, soy nuts) having additional soy protein in the supplement form can cause you to consume a very high amount of estrogen (estrogen dominance), changing your hormone levels. This soy product increases Isoflavones which can disrupt your Thyroid function. Also, it could possibly cause females to hold onto more fat since estrogen is fat-storing.
The more research I've been doing on supplements, the more I realize I should only have natural ingredients from the market and should keep the dosage to a normal amount. You can't go wrong with making your own smoothies at home and using all-natural ingredients. If you're making it, you know what's inside of it. Remember, it's important to keep a balance in the food that you eat (try to stick to superfoods) to have a balance in the nutrients that you're consuming.
Please do more research yourself before taking any protein shake product or supplements. It's important to analyze the ingredients and to get a doctor's or health professional's opinion as well. Find out what's best for your specific health needs.
