FAQs
How do I use organic seaweed supplements?
The dried whole leaf varieties can be soaked and added to soups, stews, salads and broths. Sea spaghetti works well as a pasta substitute or side dish. Kombu and wakame rehydrate quickly and add depth to Asian-style cooking.
For supplement use, the powdered and blended formats, including the Alkalising Seaweed Blend and kelp powder, are the most practical. A small daily amount added to a smoothie or juice is how many Detox Trading customers use them.
Iodine content varies significantly between seaweed varieties. Sugar Kelp, for example, contains the highest concentration of iodine and should be used in small amounts. Bladderwrack and wakame are also high. Dulse is more moderate. If you are new to seaweed supplements, starting with a lower iodine variety or using small amounts in a sensible approach.
Which seaweed is edible?
Many seaweed varieties are edible, but it’s important to make sure you purchase the right types from a reputable supplier. At Detox Trading, you’ll find a collection of edible seaweeds, including dulse, kelp, kombu, wakame, sea spaghetti, and Irish sea moss.
Our Organic Ocean Salad blend also contains sea lettuce (Atlantic spirulina) and dulse, which are another two lovely edible seaweed options.
Does seaweed have B12?
Certain seaweed supplements are a brilliant source of vitamin B12. While the exact levels depend on where the seaweed was harvested, nori, wakame, and kombu are particularly rich in B12.
What organ is seaweed good for?
Many people consider seaweed to be a superfood because it is so nutrient-dense. Its high levels of iodine, antioxidants and fibre make it a popular supplement for supporting the thyroid gland, heart and digestive system. However, it’s important to note that the high concentration of iodine means seaweed must be consumed carefully, as overuse may lead to hyperthyroidism.
Does seaweed interact with any medications?
Seaweed supplements tend to be high in iodine, vitamin K, and potassium. These high levels mean that seaweed can potentially interact with some medications, including blood thinners, thyroid medication, and blood pressure medications.
If you are thinking about incorporating organic seaweed supplements into your wellness routine, always double-check any possible contraindications with your doctor or medical practitioner.
What are the best seaweed supplements in the UK?
The best seaweed supplement depends on what you are looking for. For iodine specifically, bladderwrack and kelp are among the richest natural sources available. For broad mineral content, Irish moss is widely regarded as one of the most nutritionally complete seaweeds. For those following a plant-based diet, nori is one of the few reliable food sources of vitamin B12. Detox Trading stocks all of these in certified organic form, carrying Soil Association certification and full safety testing documentation.
