There are times in our lives when we may experience a sense of physical or mental fatigue and it's important to listen to our bodies and take the time that we need to rest and recover. An essential element in combating occasional fatigue is proper nutrition - following your specific Blood Type Diet, GenoType Diet or SWAMI protocol is the first step in this process. Dr. Peter J. D'Adamo designed natural supplements that provide additional nutritional support and optimize energy production.
