I have been told by the doctor I have AS. I have also been very tired, no energy. I started taking Serrapeptase and Nattokinase both are enzymes. I can not tolerate the naproxen he gave me! You take these on a empty stomach. I have been taking the supplements for the anti inflammatory benefits and they are very good at reducing pain and inflammation but I can't believe how much they have reduced my fatigue!
