The main reason to take these kinds of pills? If you work out. I got this tip from the ever-clever Jenn who suggested them to me after I complained about body aches caused from going to the gym. They totally work, too. I never feel any kind of pain now, no matter how hard I push myself at the gym. The recommended dosage on my particular fish pill bottle is 2-3 a day, but since these tablets are so damn fat - I only take one a day. Works like magic. Definitely try this out if you're ever complaining of any body parts hurting the day after going to the gym.
