I have only been taking this product for a short time but have noticed more alertness and energy overall. Well done Healthpost.

Improved mental alertness and general wellbeing Review by
  • star

After a couple of days I noticed a marked improvement in my mental alertness.
My general health and energy levels picked up after taking the pills; probably due to the lack of iodine in the diet especially if restricting salt intake.
Thanks again for your prompt and efficient service.

I'm really thankful for this product as now it has allowed me to come off the Dr's prescribed treatment for an under active thyroid & has enabled my thyroid function to come into the normal range (just). My Dr. is happy about this & continues to monitor it with yearly blood tests.

A good all rounder Review by

This is a great addition to my daily vitamin intake - I've noticed a marked improvement in energy and stamina since taking it. A good all rounder and easy to swallow.

Great product, would recommend Review by
  • star

This product really helps with day to day living, keeps my blood sugar levels balanced and have noticed it gives me a good sense of wellbeing. Great for 'that time of the month' and also when doing strenuous exercise.

Very good for thyroid treatment Review by
  • star

My husband was told by a specialist that he should take a Kelp tablet every day to prevent his thyroid from producing fluid which then formed a lump which needed to be drained. He has taken kelp every day for a few months and has had no more lumps and no more problems. I take a kelp tablet every day myself as I believe in this product to keep my thyroid normal.

I have been taking 'one a day' for about two years or more. After a diagnosis of thyroid nodules the hospital consultant gave me the options of having my thyroid removed,or zatted and pills for the rest of my life. He didn't advice me taking kelp or iodine, in fact he gave me very low dosage pills that inhibited iodine in preparation for a thyroid removal. I decided to continue with Thompsons kelp and discarded the prescription pills after about 6 months and my thyroid recovered. So now I religiously take one a day. I like the fact that Thompsons claim their kelp is screened for toxins.

I have been taking these for 4 months now on the recommendation of my naturopath (along with a better multivitamin). I have more energy and i am not thoroughly exhausted or getting sick every few weeks as a result of my terrible job. I have also lost weight. Brilliant product.
