NOW Kelp 150 mcg (200 Tablets)
A 200-count jar of kelp tablets as a no-frills natural iodine source β over seven months of daily doses for pocket change.
The appeal here is the sheer simplicity: one small green tablet a day delivers 150 mcg of iodine straight from brown seaweed kelp, right in line with a typical daily need. NOW Foods has been making honest, unfussy supplements since 1968, and it shows in the cost per dose. It's no miracle pill, but it's a fair, cheap way to top up your iodine.
Reasons to buy
- 200 tablets at one a day lasts well over seven months β the per-day cost is negligible
- 150 mcg of iodine from actual kelp (brown seaweed), not synthetic potassium iodide
- The 'easier to swallow' tablets are genuinely small with almost no seaweed taste
- Vegan, non-GMO and kosher, made in the USA under A-rated GMP certification
Reasons to consider
- 150 mcg is a fairly low dose β longtime buyers of the old 325 mcg version feel shortchanged
- Iodine is tricky: with thyroid conditions or medication you really should check with a doctor first
- Works best paired with selenium, which isn't in the formula
What's in it and where it comes from
Kelp is a large, leafy brown alga that grows in actual 'forests' in cold ocean waters. NOW harvests its natural iodine and presses it into a small green 150 mcg tablet. That's the whole story β no filler circus, just kelp powder with a couple of plant-based excipients.
For anyone who'd rather get their iodine from a natural seaweed source than from synthetic potassium iodide, that's exactly the draw. The bottle holds 200, the dose is 1 tablet a day with a meal, and it's vegan, non-GMO and kosher.
What users actually notice
The common thread across reviews is how easy it is to live with: one tablet with a meal, no nasty aftertaste, slots right into a morning routine. Some report feeling more energetic, though that's the kind of effect that's hard to pin on a single supplement.
Opinions on tablet size split β most find it small and easy to swallow, while a few call it slightly large but 'goes down fine with water'. The recurring gripe is the dose: loyal buyers remember the old 325 mcg version and find 150 mcg a little thin for the same money.
Who is it for?
Great for anyone after a cheap, natural iodine source to top up daily intake β think people who eat little fish or seaweed. Skip it if you're already on thyroid medication or another iodine supplement, or have a thyroid condition; clear it with your doctor first in that case.
FAQ
How many should I take a day?
One tablet daily, ideally with a meal so it sits easier on the stomach. At that rate a single jar lasts well over seven months.
Is it safe if I have thyroid issues?
Not without a conversation first. Iodine acts directly on the thyroid, so with any thyroid condition, thyroid medication or during pregnancy, check with your doctor before starting.
