This "evidence" is highly questionable. There's other evidence, i.e., that taking aspirin with DGL or vitamin C does not damage the stomach lining, have led to new formulations decades ago. In fact, high doses of aspirin have been sold in Europe combined with vitamin C for as long as I remember - Aspirin C by Bayer and Upsarin C by UPSA. There's other evidence, too, that aspirin protects against cancer.
