My thyroid level was a bit low in June (4.7). I immediately ordered and began taking Natural Factors Thyroid Health Formula, 3 caps per day. Noticed an increase in energy right away, as well as less trouble getting going in the morning. Just had my level retested at the end of September -- perfect! 3.3!

Have noticed an increase in energy

I had cancer and had my thyroids removed in 1983. It has been a battle ever since with thyroxine/T4 supplementation. This product would improve even more if the L-Tyrosine was lowered. Coupled with Ultra Guggulow it does help with energy and cold legs/feet

Something in this gave me headaches so I had to discontinue, but I did initially get a nice energy boost from it. (My thyroid test is on the hypothyroid side)

PCOS

If you have PCOs you have most likely an underactive thyroid gland, or are bordeline. This formula has improved my PCOS. My androgens are lower and my insulin sensitivity has improved.
