For Dietary Supplementation "I am 55 years old, and since taking Omega-3 1000 mg, I have noticed glowing skin, and my joints are not as stiff. But the negative is tender breasts, stomach discomforts such as gas, bloating, and lower abdominal pain. I feel like I am moving in reverse toward menstruation. Why?"

For Dietary Supplementation "I started taking it about a week ago. To help with pain and inflammation. It has helped some unexpected things I have. But... I ended up having horrible heartburn, burping, and bloating. And I only took 1 a day. I took it with food. Ended up having to use Tums and apple cider vinegar. Had to stop it. And now I feel fatigued and crappy. I am super sensitive to everything. I really thought this was going to be a good thing. It's a bummer that I can't continue it."
