Actually I joined MyFitnessPal. The products made me feel very jittery and then I would feel low. I explained my doctor had a long time ago 10 yrs. I had dental surgery and was away from the center for a year and gained a lot of weight back I was lied to and that is unjust. She asked where I buy my vitaimins and mega 3 fish oil and when I told her Wal-Mart she went off on a tangent about how she wouldn't buy ANTHING like that from Wal-Mart and that it was probably their stuff that was making me feel bad, even though I have been taking them for several years now and I've been fine until I started taking their products.
When you are considering the potential benefits of products look for meta-analysis studies that take in all the sound research available. One-off studies that get a significant result are not evidence of anything. Only when an effect is repeated in many studies by many scientists should you believe.
