Dr. Tedone and the Deanna Protocol researchers have discovered a new, more effective version of the Deanna Protocol, which is patent pending and has a proprietary ratio of substances that cannot be found in any other version of the Protocol. This new Deanna Protocol is the only Deanna Protocol endorsed by Dr. Tedone and will be available only at deannaprotocol.com, likely starting in February (but there may be some delay due to COVID and its impact on shipping logistics of raw materials). Until this new, more effective Protocol is available, you can still purchase the old version of the Deanna Protocol at Simplesa Nutrition. Although this version does not work as well, it still is better than taking nothing and you should still notice a difference. The version of the Protocol we recommend purchasing from Simplesa is the Core+ Powder. Nothing more is needed.
