## Overview

## Description

Do you get enough iodine? Iodine, a trace element essential to life, is important for various functions in the body—particularly when it comes to thyroid health. Its primary role is in producing the thyroid hormones T3 and T4, two important hormones for optimal thyroid function. This is important because the thyroid gland acts as the body’s thermostat, making it a major maintainer of metabolism and supporting fat burning for energy. The problem is, most Americans don’t get enough iodine in their diet. And a major source of iodine is table salt—which most people are told to avoid. Getting iodine through a supplement is an easy way to get what you need while avoiding excess salt intake. Our Sea-Iodine™ supplement supplies 667% of the recommended daily value of iodine and is non-GMO, gluten-free, vegetarian and manufactured in the USA.

Review: If you don't have your health , you don't have anything! - The functional medicine doctors say that almost all Americans are deficient in iron! I take this as a regular supplement every morning. Seems to work great for me!
Review: Great buy! - Very small capsule which is nice. I only take it 3-4 times a week for health. I'll purchase again.

## Questions & Answers

**Q: Where does iodine come from?**
A: Iodine is found in soil and the ocean—which is why high concentrations are found in marine algae and seaweed, as well as fish and shrimp. Iodine is also found in dairy products and can be added to table salt or supplements.

**Q: What does iodine do for you?**
A: Iodine is considered an essential trace mineral for life. Getting enough iodine is an important part of optimal health, largely in part because of its role in producing thyroid hormones crucial to healthy thyroid function.

**Q: How much iodine do you need per day?**
A: The recommended daily amount of iodine needed per day is around 150 mcg. However, since healthy stores can be depleted depending on your level of activity, look for supplements that go beyond daily recommended values.

### ⭐⭐⭐⭐ Easy to Take, But Use With Caution—Check Thyroid Levels Regularly
*by P***P on February 13, 2026*

I picked up this Sea-Iodine supplement because I’d read some research suggesting iodine from kelp and bladderwrack might help support thyroid function, and potentially assist with weight loss. I was looking for something that could help stimulate my thyroid as part of a broader weight management plan. The pills are tiny and easy to swallow, with no noticeable bitter taste. They arrived in good condition, none broken or damaged. While taking these, I did notice I dropped a pound or two, but I was also dieting, exercising, and stacking other supplements (like creatine, green tea, and caffeine) to help boost metabolism and thermogenesis. If you’re looking for something to magically drop weight, this won’t do it alone—you really have to combine it with diet and activity. A word of caution: After finishing the bottle, my doctor flagged that I might have hyperthyroidism, so now I’m getting blood work done to check my thyroid levels. I can’t say for sure if the supplement caused it or if it’s just a coincidence, but if you’re going to try this (or any iodine supplement), definitely talk to your doctor first and keep an eye on your thyroid health. It’s possible that too much iodine can throw off your thyroid function, even if that risk is low. Other than that, I didn’t notice any side effects while taking the supplement. If you’re supplement-savvy and track your health closely, this could be a useful addition, but always check with a medical professional, and get your labs done every so often to be safe.
