IoBio Organic Seaweed Blend — Iodine, Thyroid & Natural Detox Support

Iodine deficiency is the leading cause of preventable thyroid dysfunction globally, yet it remains surprisingly common in the UK — particularly among vegans and those who don't eat fish. IoBio Organic Seaweed Blend provides a rich, natural iodine source from organic bladderwrack seaweed, combined with complementary thyroid-supporting botanicals and minerals for comprehensive thyroid and metabolic support.

Why You'll Love It

  • Organic bladderwrack seaweed — a naturally occurring iodine source that provides the broad spectrum of trace minerals present in seaweed (not just isolated iodine)
  • Thyroid hormone support — iodine is essential for the synthesis of T3 and T4 thyroid hormones, which regulate metabolism, body temperature, energy production and weight management
  • Selenium — essential cofactor for thyroid hormone conversion (T4 to active T3); deficiency impairs thyroid function even when iodine is adequate
  • Zinc — supports normal thyroid hormone production and contributes to protection of cells from oxidative stress
  • Natural detox support — seaweed contains alginates that bind to heavy metals in the digestive tract and support their elimination
  • 60 vegan capsules — two-month supply of daily thyroid and iodine support

Key Ingredients

Organic Bladderwrack Seaweed Powder (Fucus vesiculosus) · Organic Kelp (Ascophyllum nodosum) · Selenium (as Selenomethionine) · Zinc Citrate

How to Use

Take 1–2 capsules daily with water and a meal. Important: Do not exceed recommended dose. Iodine from seaweed sources can vary; if you have a thyroid condition or are taking thyroid medication, consult your GP before use.

Who is IoBio most suitable for?

IoBio is particularly beneficial for vegans and vegetarians (who may have lower dietary iodine from fish and dairy absence); those with fatigue, slow metabolism or weight management challenges; and anyone concerned about thyroid function who wants natural iodine from whole-food sources.

Can IoBio be taken with thyroid medication?

If you are taking levothyroxine or other thyroid medications, it is essential to consult your GP before taking IoBio. Iodine supplementation can significantly affect thyroid hormone levels and medication requirements.

Is seaweed iodine better than potassium iodide?

Seaweed provides iodine in its naturally occurring matrix alongside fucoidan, alginates and a range of trace minerals that work synergistically. Many practitioners prefer food-form iodine for its broader nutritional context and reduced risk of excessive isolated iodine intake.

Is IoBio vegan?

Yes. Seaweed is a plant-derived marine ingredient, and all other components of IoBio are plant or mineral-derived. Certified vegan and vegetarian.

Lovely piece overall

Really like this piece overall. This is the kind of garment you can throw on and instantly feel put-together. I’ve styled it with trainers and boots and it works both ways. Length is a bit longer/shorter than I expected, but nothing major.

Really good, just a small tweak

This piece is a solid find. For the price, this garment really surprised me. The quality is solid, the stitching looks neat and it doesn’t feel flimsy or thin like some things I’ve ordered elsewhere. The colour is a touch different to the photos, but still very wearable.

So happy to hear you’re enjoying your order, thanks for letting us know!

Great value for money

Really like this piece overall. For the price, this garment really surprised me. The quality is solid, the stitching looks neat and it doesn’t feel flimsy or thin like some things I’ve ordered elsewhere. I might have preferred a slightly thicker fabric, but it still feels good on.

So happy to hear you’re enjoying your order, thanks for letting us know!
