This is a review of the vitamin B-12 v supplement from the company Zhou Nutrition. This vitamin B-12 supplement supports your thyroid function which has a great effect on your immune system and metabolism. The all natural ingredients make sure that your thyroid functions normally.

If you have issues with your immune system then please read on and find out what this vitamin B-12 supplement is all about.


The ingredients of this particular supplement are as follows:

  • L-Tyrosine: Thyroxine and Triiodothyronine are thyroid hormones that cannot be produced without this particular amino acid.
  • Bladderwrack and Kelp: These seaweeds are full of Iodine which helps produce thyroid homones
  • Ashwagandha and Schizandra: These herbs have a long standing tradition in Chinese medicine and have been used for centuries to help improve thyroid activity
  • Cayenne pepper (also known as Guinea spice): supports circulation  which means all the important supplements will reach their destination in your body.
  • Zinc, Selenium, Molybdenum, Manganese, Magnesium, Copper: All these minerals are needed to produce thyroid hormones. Without them the thyroid does not function.
  • Vitamin B-12: This is the most complex of all vitamins. Aside from other functions it is absolutely essential to the functioning of the thyroid.
  • Vitamin D: Created in the body after exposure to the sun. Most of us have responsibilities that keeps us inside most of the day, limiting our exposure to the sun and causing a shortage of vitamin D in our system. This vitamin D deficiency is being named as a cause for cancer such as skin cancer and colorectal cancer. Aside from possibly causing cancer a lack of vitamin D has proven to decrease the efficiency of your immune system, weaken the bones and affect brain function. This is the reason why most doctors prescribe vitamin D supplements to their patients in high doses. And this is why we added it to our special blend.

Interestingly enough the website state that the supplement contains vitamin D but this is not metioned on the label of the jar. This strikes me as slightly odd.


The dosage is 2 capsules daily, preferably with meals.

The supplement contains 1667% of the daily value. That is definitely a boost!


The cost for a jar of 60 capsules that will last you 30 days is $19.97. This is the price on Amazon and on the website itself. Amazon states that this is a 60% discount from the listed price of $59.99. Free shipping is available within the United States.


Zhou Nutrition offers a 60-day money back guarantee. This means that if you are in any way not satisfied with the product you can ask for your money back. All they ask is that you write a short note explaining why you are not happy with your purchase. If you do that they will give you a full refund.

There are many reviews on Amazon and they are very positive. Over 75% of the reviewers rate the Thyroid Supplement with Vitamin B-12 with five stars out of five.


What I like about the Thyroid Supplement with Vitamin B-12 is that it is an all natural product. I am also impressed with the positive reviews. It really works!

I am not very happy with the promise of vitamin D on the website which is absent from the list of ingredients on the label of the jar. Does it contain vitamin D or not?

Nowhere does it say if there are any known side effects. It would be nice if they even simply stated that there are no known side effects. It would ease my mind.
