N-Acetyl Glucosamine 90c by Allergy Research Group
N-Acetyl Glucosamine by Allergy Research Group provides glucosamine attached to an acetic acid molecule, whereas glucosamine sulfate has it attached to a sulfuric acid molecule. Although research suggests that glucosamine sulfate is better absorbed than NAG, individuals sensitive to sulfur may tolerate NAG better.*
Allergy Research Group suggests taking 1 N-Acetyl Glucosamine capsule three times daily, or as directed by a healthcare practitioner.
