NOW Foods Kelp 325mcg 250 Veg Capsules

What this is

NOW Foods Kelp 325 mcg is a dietary supplement that supplies iodine from organic kelp, packed as 250 veg capsules in a single bottle. The Supplement Facts panel declares one nutrient and one only: iodine, 325 mcg per capsule, sourced to organic kelp — Laminaria spp., whole plant. Against the panel's own percentage column that figure is 217% of the Daily Value. The front of the bottle describes it as "325 mcg of Natural Iodine" and carries a "Super Green" badge, a Non-GMO mark and the words "Vegetarian/Vegan"; the band across the top of the label reads "Botanicals/Herbs".

What's inside

Kelp is not a single plant but a group of large, leafy brown seaweeds that grow in dense underwater stands in the colder parts of the world's oceans. It has been eaten for centuries as a staple ingredient in Chinese, Japanese and Korean cooking, which is the context the bottle itself gives for it. What ends up in the capsule is that seaweed, dried and milled — the panel's nutrient row points at the plant rather than at a manufactured mineral salt added to it.

Two details in that row repay a close reading. The first is Laminaria spp. — a genus name followed by the abbreviation for "species" in the plural. The label is saying the kelp comes from more than one species within the Laminaria genus rather than naming a single one. The second is "(Whole Plant)", which marks the part used: the entire alga rather than a fraction of it. The bottle gives no extract ratio, which is consistent with dried whole plant material rather than a concentrate.

The rest of the panel is short. Other ingredients are Cellulose Powder, Cellulose (capsule), Stearic Acid (vegetable source) and Silica — four entries, two of them cellulose doing two different jobs: once as powder inside the capsule and once as the capsule shell itself. That cellulose shell is what sits behind the "Vegetarian/Vegan" line on the front. The panel assigns no role to the stearic acid and the silica, so neither do we. For background on plant-based supplement ingredients as a category, the NIH Office of Dietary Supplements publishes a fact sheet on botanical dietary supplements, written about the subject generally and not about this product.

Supplement Facts

How to use it

The suggested usage printed on the bottle is "Take 1 capsule daily with a meal." Storage is printed alongside it: "Store in a cool, dry place after opening." Because one capsule is one full serving, a 250-capsule bottle works out to a 250-day supply — a figure derived by dividing the capsule count by the serving size, since the panel prints no servings row of its own. The panel also notes that "Natural color variation may occur in this product."

Who it's for

This is a product for adults, and the label says so directly. Within that, the bottle suits someone who wants their iodine to come from a botanical source: what the panel declares is a seaweed, named by genus and by the part used. At one capsule a day, the 250-count bottle covers a long stretch without reordering. This item is listed in our Herbs & Botanicals and Supplements sections.

Good to know

The caution printed on the bottle reads: "For adults only. Consult physician if pregnant/nursing, taking medication (especially thyroid medications), taking other iodine supplements, or have a medical condition (especially any thyroid disorder). Keep out of reach of children." One capsule supplies more than twice the Daily Value, which is why the label's instruction about other iodine supplements is worth reading carefully before this goes into an existing routine.

The allergen statement, printed verbatim: "Not manufactured with yeast, wheat, gluten, soy, corn, milk, egg, fish, shellfish or tree nut ingredients. Produced in a GMP facility that processes other ingredients containing these allergens."

The bottle carries a "GMP Quality Assured" seal and a Non-GMO mark, and a small circled letter K appears on both the front and the panel; the bottle names no certifying agency for that mark. The address block on the panel gives NOW Foods at 395 S. Glen Ellyn Rd., Bloomingdale, IL 60108, USA. NCCIH publishes general guidance on dietary and herbal supplement safety, again as background rather than as comment on this item.

Frequently Asked Questions

How much iodine does one capsule contain?

One capsule contains 325 mcg of iodine, which the Supplement Facts panel gives as 217% of the Daily Value. Working backwards from those two printed figures puts the reference Daily Value at 150 mcg, so one capsule supplies a little over twice it. The panel declares the iodine as coming from organic kelp rather than from an added mineral salt.

What does "Laminaria spp. (Whole Plant)" mean on the label?

Laminaria is the botanical genus of the kelp used, and "spp." is the plural abbreviation for species — it indicates that more than one species from that genus may be used rather than one named species. "(Whole Plant)" identifies the part used: the entire seaweed, rather than an extract drawn from one section of it.

Are the capsules suitable for vegetarians and vegans?

Yes — the front of the bottle prints "Vegetarian/Vegan" and the panel lists the shell as Cellulose (capsule), with no gelatin among the ingredients. The other listed ingredients are Cellulose Powder, Stearic Acid from a vegetable source, and Silica.

Can I take this alongside another iodine supplement or thyroid medication?

The label tells you to consult a physician first in both cases. Its caution names "taking medication (especially thyroid medications)" and "taking other iodine supplements" among the circumstances calling for medical advice before use, along with pregnancy, nursing and any existing medical condition. That decision belongs with your own clinician rather than with us. The NIH Office of Dietary Supplements also publishes a general consumer guide to dietary supplements.

How is the order packaged for delivery?

Orders ship in plain outer packaging. It will not show the Gear Isle name. Inside, the bottle carries the NOW Foods label shown in the product images. The same packaging policy applies across our Health & Wellness range.
