what do you think of these suppliments?

Hi there,

I know a lot of people training with weights have problems in their joints (elbow/knees) Do you think joint suppliments will help or it`s BullS ?

Is an EFA (omega 3,6,9/flax etc..) suppliment worth the hype? Have you seen
an improvement while taking them?

last one... gugglesterone is a plant which is said to keep thyroid healthy especially while dieting when thyroid is less effective because of the decrease in calorie intake, has any one had a good/bad experience with it?

Thanks Guys & Gals
