I recently read that vitamin C powder in water can help with the absorption of thyroxine hormone, so I bought this to try it out. Very happy with it so far. The taste is a little sour, but nothing unbearable.

I'm so disappointed in this. Received my order this morning and discovered that it contains white Korean ginseng. Unless I am going completely mad, this is not on the ingredients listing, and I'd never have ordered it if I'd known.

I have noticed a reduction in migraines since taking this product. Have just re-ordered.

My husband has been taking this for only a few weeks, and he has just had a vitamin D blood test result of 65. He has only been taking two sprays a day (2000 iu), so quite a lot less than the dosage on the bottle. The taste is nice, which is a bonus.

I was thrilled to be able to order this book, especially being free. It was a very informative read. However, when sending it, it should have been utterly obvious that if you squeeze a book into a box that isn't as long as the book, it is going to arrive scrunched up! It is readable, but only just. Whilst I can't complain too much about a free gift, I thought a lot better of iHerb.

I previously used this alone and didn't find it particularly helpful. However, I was recently diagnosed with hypothyroidism, after at least 15 years of symptoms, and prescribed levothyroxine. I have a goiter and was experiencing neck pain and discomfort, but since I started taking this, these neck symptoms have lessened noticeably. Therefore, I think it's a good support for additional thyroid medication, but probably not really 'strong' enough on its own.

I don't often give products 5 stars, but I'm really thrilled to find a zinc that I can take, as they all seem to really hurt my stomach usually. I strongly suspect I have copper overload, and I am definitely noticing some benefits from taking this zinc, but it will be a long road to getting rid of the excess copper. For those who find zinc supplements hurt their stomach, I thoroughly recommend taking this zinc with a heaped teaspoon of coconut oil (which is good for you anyway). I don't know why the coconut oil helps, but it really does.

I had high hopes for this product, as it was supposed to be non-constipating, which is a problem I've found with regular calcium supplements. Unfortunately, this had the very opposite effect, accompanied by awful gas and griping pains. I suspect the magnesium in it as the cause, as I cannot tolerate oral magnesium supplements.

I bought this particular product because I was looking for a coenzyme q10 with no soy, which seems worryingly hard to find. The capsules are quite small and easy to swallow.

I may well have reviewed this before, as I have used this product for some time on and off. My reason for reviewing now is because I have tried so many riboflavin products that sounded better, eg. coenzymated riboflavin, and sustained release, but I always end up coming back to this one, because it works so much better for me. I space it through the day for my migraines (I take four), and it most definitely helps both that and my TMJ (jaw) issues. I won't be changing again, for as long as this product is being sold!
