In lab rats it was shown to cause perforations in brain tissue when given in larger amounts, amounts which are I belieive unrealistic for humans to be able to consume.
In certain countries there are restrictions on aspartame already which I believe will follow into the UK eventually. Extreme Nutrition has already begun changing Extreme Whey away from aspartame to sucralose which is sugar with the carbs removed, we are also increasing the protein content to 70% and NOT increasing the price. |
