Thyax is a food supplement by the company  Progressive Health. It will help bring your thyroid hormone levels back to normal. It will also up your T3 and T4 levels which will help your thyroid to function properly.


The main ingredients of this supplement are:

  • Vitamin-B : These vitamins influence your energy levels, your mood have an effect on your nervous system and stimulate the healing of wounds.
  • Amino Acids: A lack of amino acids has been connected to hypothyroidism. Tyrosine is needed for thyroid hormone production.
  • Iodine: A lack of iodine (even a small lack) can create problems such as thyroid disorders and in children developmental problems.
  • Vitamin B1
  • Vitamin B2
  • Vitamin B3
  • Vitamin B6
  • Folic Acid
  • Vitamin B12
  • Vitamin B5
  • Kelp
  • Magnesium
  • Zinc
  • Selenium
  • Copper
  • Manganese
  • Molybdenum
  • Acetyl L-Tyrosine
  • L-Phenylalanine
  • Hypromellose (vegetarian capsule)
  • Rice Powder
  • Magnesium Stearate


One serving size is four capsules. So the dosages is four capsules a day. The capsules contain so much of the main ingredients that they exceed the daily value many times. This is definitely a vitamin B boost.

Possible Side Effects

A review posted on the website mentions that someone experienced a “high” when he switched from another product to Thyax overnight. It only lasted one evening and has not occurred afterwards.


A one month supply consisting of one jar of capsules costs $54.95. If you opt for a three month supply you get a significant discount. The price goes down from $219.80 to $164.85 and if you buy enough for four months the price is $219.80 you get two of the four jars for free and you will not have to pay for shipping.


Progressive Health offers a staggering 180 days guarantee. This gives you enough time to test the product and actually notice the difference. If you are unhappy about the product in any way Progressive Health will give you a full refund. This excludes shipping costs.

The Progressive Health website claims that 9 out of 10 customers are satisfied with Thyax. Only one reviews has been posted however. There are also a number of comments but those are mainly questions about thyroidism or about Thyax and do not contain any reviews.


Progressive Health is very secure about the positive effects of Thyax. This big vitamin boost will have an effect on your thyroids. The money back guarantee of 180 days is excellent and will give you a real opportunity to test the product and see if it really works for you. The ingredients of the capsules contain huge boosts of vitamins. The percentages of the daily value are not to be trifled with.

Unfortunately the website only offers one actual review. It is a very good one, and it seems an honest one as it mentions a side effect. But if they claim that 9 out of 10 customers are happy then I would have expected a few more reviews.

The mentioned side effect is a bit of a worry too. The website does not offer a list of possible side effects but the review mentions it. I would have liked to to know more about it.
