Description: 30 day supply. The omega-3s in TheraTears Nutrition come from organically grown cold-pressed flaxseed oil, and premium molecularly-distilled (mercury-free, PCB-free) fish oil. This flaxseed/fish oil blend supplements omega-3 metabolism better than flaxseed oil or fish oil alone, and makes TheraTears Nutrition great for healthy tears and eyes, and great for healthy saliva and oral health.* Gluten free.
