A good alternative to taking prescription medicines. Review by

I am very certain that my energy levels have improved over the past few weeks, having been diagnosed with mild hypothyroidism. Personally, there are just two negatives. They are a large tablet to swallow with an unpleasant aftertaste. However, I intend to overlook it as they appear to be doing the job intended so I will keep on taking them.

Hoped it would make a difference Review by

Found the tablet too hard to take and had to force it down. I don't normally have trouble taking tablets but this was horrible and made me gag. From the time I did manage to take it I unfortunately didn't notice too much difference.

After being diagnosed with mild hypothyroidism, and the doctors being unwilling to prescribe anything to help, I found this product. Within a few weeks, the results were obvious. I had so much more energy, less headaches, and I started to lose weight! I have just ordered another 2 months of this product, and I am extremely impressed with how well it works.

This is the best thyroid support that i've tried - I put it down to the fact that there is a higher tyrosine content than all others.
