Starwest Botanicals Organic Kelp Powder

Starwest Botanicals Organic Kelp Powder is one of nature's richest sources of iodine — a pure, USDA Organic powder of Ascophyllum nodosum (Norwegian kelp) sustainably harvested from the clean coastal waters of Canada, delivering a broad spectrum of minerals, vitamins, and unique marine bioactives in every tiny serving.

Available in two sizes: a 100 g trial size repackaged by Superfoods NZ — perfect if you'd like to try kelp powder before committing to a larger quantity — and the full 453 gram size.

Why you need it

Iodine is an essential mineral that the body cannot produce on its own — and it is critical for the production of thyroid hormones T3 and T4, which regulate metabolism, energy production, body temperature, and healthy development. Despite its importance, iodine deficiency remains one of the most common nutritional deficiencies worldwide, particularly in populations that don't regularly consume seafood or iodised salt.

Kelp is one of the most concentrated natural sources of iodine available. But kelp offers far more than iodine alone. Ascophyllum nodosum is particularly rich in fucoidan — a sulphated polysaccharide unique to brown seaweeds that has been the subject of extensive research for its immune-modulating, anti-inflammatory, and antioxidant properties. Kelp also provides alginates (soluble fibre that supports gut health and may help bind heavy metals), along with potassium, magnesium, calcium, iron, vitamins, amino acids, omega-3 fatty acids, and a broad spectrum of trace minerals that are increasingly absent from land-based foods.

Important

⚠️ Do not exceed the recommended serving size. Kelp is extremely high in iodine — excessive iodine intake can disrupt thyroid function, particularly in those with existing thyroid conditions (both hypothyroidism and hyperthyroidism). If you have a thyroid condition or are taking thyroid medication, consult your healthcare practitioner before use. Not recommended during pregnancy or breastfeeding without professional guidance. Keep out of reach of children. Store in a cool, dry place away from direct sunlight.
