NOW Foods Kelp comes from a large, leafy brown algae that belongs to the seaweed family and grows in the colder waters of the world's oceans. It features marine minerals, including potassium, magnesium, calcium and iron. It is also an excellent source of iodine, which has been shown to support healthy thyroid function. Your thyroid gland is responsible for producing the hormones that support normal cellular metabolism. As with most green foods, kelp also delivers vitamins and cell salts essential for good nutrition.

Customer Ratings & Reviews

Kelp is rated 4.7 out of 5 by 7.
Rated 3 out of 5 by from good value iodine I've been using this kelp to add additional iodine to my daily multivitamin/mineral supplement. It tastes nasty like dead fish, so I add a tad of water and drink it quickly then chase it. I don't know if it's helping me, but I like the convenience of using however much I want for the dose/amt I desire. Great price, but tastes gross.

Rated 5 out of 5 by from Convenient way to get iodine If you don't need an exact dose each day, but prefer to sprinkle it on your food, this is a good way to add iodine to the diet. I put it in an old clean spice jar with the sprinkle top, and use it each day on something savory. The taste is not overly intrusive at all. I've used celtic sea salt and himalayan pink salt for years and found I was needing iodine. This works fine. It is a very fine powder and hasn't clumped up on me at all. Very easy to sprinkle.

Rated 5 out of 5 by from Used to Make Vitamin for Dogs I have purchased this item on more than one occassion to make a powder vitamin mix to be used in my pet foods on a regular basis. The pricing and quality of this item has been great.

Rated 5 out of 5 by from Kelp is great for good health Kelp is much better for health than salt - kelp has an array of minerals and other substances in the same proportion as sea water - and body fluids. I use kelp for cooking instead of salt whenever possible. And I sprinkle kelp on salads, vegetables, etc. Tastes great and very healthy.

Rated 5 out of 5 by from Awesome Kelp I take kelp supplement to help supply iodine. This kelp powder smells fresh and I can hardly taste it when I put it in my smoothies. It comes with a tiny serving scoop for dosage measurement. 2 level scoops will supply 270 mcg of iodine & 200mg of kelp, and there are 1135 servings at that dose. I see excellent value!

Rated 5 out of 5 by from Good in Green Smoothies Kelp powder is a good nutritional addition to green smoothies.
