What's safe to take with Synthroid for weight loss?

I have been taking synthroid for hypothyroidism, but my weight is still fluctuating quite a bit.  I run and eat right but still have 10-15 pounds that don't want to leave my waistline.
I look at weight loss supplements, but most of them caution about taking the product if you have a thyroid condition.
Is there a SAFE weight loss supplement I can take while taking synthroid?  Any suggestions?

The very best thing you can do for yourself if you are having trouble losing weight is to make sure that your thyroid meds are adequately adjusted for YOU, personally, not just "in normal limits".

Please post results of recent thyroid lab work along with reference ranges that vary lab to lab and have to come from your own lab report.

Please also post your meds history.
