ThyNatural was developed to help you harmonize your life so you can be yourself again, focused and full of energy.

ThyNatural’s Goal

The numbers are alarming: about 20 million Americans suffer from some form of Thyroid disease today, more than in any other country in the world.

Even more alarming, only 2 out of 5 are aware of their condition, and 1 in 8 women will develop a thyroid disorder during her lifetime. This could lead to weight gain, heart disease, osteoporosis, even infertility, and will require life-long treatments

Yet, it could be avoided naturally, and you could rebalance your thyroid functions, with just a little help.

CRI Naturals is proud to offer you the best quality natural supplement to fight brain fog, fatigue and other unbalanced thyroid issues.

ThyNatural will help you take control of your body and be the person you deserve to be, happy and healthy.


All of my numbers are now within the normal ranges!



Seattle, Washington


I had my bloodwork done in January, and my TSH was 6.3 (high), my T3 and T4 were also completely out of whack, and my thyroid enlarged. I told my endocrinologist I had just started taking this. She agreed to give it a month or two as she liked the ingredients (and the right amount of iodine, not too much). I went back 2 months later, and my numbers were better. I went back last week, and all of my numbers are now within the normal ranges. Amazing. This stuff really really works and is worth a shot before going on life-long thyroid medication that includes tons of other side effects.

Will be a happy customer for life!



Miami, Florida


I've been taking this for 3 weeks and I haven't felt this great in a long time! I have reverse T3 hypothyroidism, which has made it very difficult to lose weight. I'd already made some dietary changes at the advice of my former naturopathic doctor, but weight loss was still slow and my energy was not there. Now that I've been taking these twice daily, I fall asleep soundly by 10 and wake up ready for the day between 5:30-6. I've lost almost 10 pounds in 3 weeks. Will be a happy customer for life!

Increased energy, better focus and more hair...



Austin, Texas


This has given me more energy, increased my focus and helped me to get back to exercising. And decreased my hair loss! Before starting this supplement, I was sleeping 15 hours a day. I had my thyroid checked and the physician said that my levels were within the normal range. I still felt as though my TSH levels were low so I decided to try a product that would help support my thyroid's function. After reading reviews of many supplements, I chose ThyNatural because it seemed to be the most natural and it is from a company within the USA. I am very pleased with this supplement and will continue to use it.
