I am a healthy 65 y/o female who HAD Chronic sinusitis for 30 years until I ordered Magnesium Lysinate Glycinate for inflammation. Never did I consider that it would help my sinuses. I took 2 tablets at bedtime and about an hour or so later my sinuses started draining and draining and draining. Best surprise of my life! That was about 4 months ago, and my sinuses are perfect as long as I take my magnesium pills every evening. I ordered Doctor's Best.
