Iodine from Kelp

It's difficult to genuinely rate a supplement as the effects can be slow to recognize. Thus, I can tell you I've been looking for a good kelp source for ingesting this essential element and by jove I think I've got it~

Organic plant based iodine

This is my go to iodine supplement. It is organic, plant based and therefore more bioavailable. This particular one is extremely potent at a high dose. Great for when you need extra when exposed to more radiation (flying in airplanes, spending lots of time on the computer or having medical procedures that expose you to radiation). I like that I can use this as is for those times I need extra or I can break them up into smaller doses if I just want a daily iodine support for my thyroid to function well. They also carry a smaller more daily dose option which I buy sometimes too. I appreciate the glass bottle and attention to detail and quality that Triquetra puts into their supplements.

Glad I Made The Purchase

I received my labs and found that I needed iodine. I was experiencing constant fatigue and brain fog. After taking the supplements for a couple of weeks I noticed a difference in my energy and focus. Will continue to purchase this supplement.

Hypothyroidism

Unfortunately, this didn't help my T4 numbers. I had been on the 250mg for 3 months (I think it was around that), then the 1500mg for 3 weeks. My numbers actually went down in 3 months since last testing. I had to be started on an Rx. :(
However, I do like the mineral complex in their mixes, so I'm staying on the 250mg. I could tell a difference in overall well being. Little more energy and clearer thinking.
