Benefits
-
Supports Thyroid Health:
Our sustainable Scottish seaweed is 100% pure, organic and rich in essential iodine. This nutrient is necessary for healthy thyroid function to support a host of bodily functions. Iodine deficiency can lead to thyroid disorders and potential health issues.
-
Energy Boost:
Iodine offers a natural and plant-based energy boost due to the important role it plays in thyroid health. When your thyroid gland is functioning optimally with sufficient iodine, it helps maintain a balanced metabolic rate, ensuring your cells receive the energy they need to perform their various functions.
-
Balanced Metabolism:
Sufficient iodine intake makes the thyroid produce hormones, these in turn help regulate your metabolic rate to ensure a healthy functioning metabolism. The polyphenols within our Scottish seaweed have also been scientifically proven to manage blood sugar release for weight management.
-
Cognitive Function:
Iodine is necessary for optimal cognitive function as it is essential for the production of thyroid hormones, which play a key role in brain development and maintenance. These hormones aid in energy supply to the brain, regulate neurotransmitters and support overall cognitive function. Insufficient iodine can lead to cognitive impairments, making it crucial for brain health.
Did the questionnaire and it said that I needed iodine as a vegetarian.
3 months into taking this my hair shedding was extreme. I take a multivitamin with 100% of the RDA of iodine in it anyway so it would appear that my GP was correct in thinking that the hair loss I was experiencing was due to too much iodine. 6 weeks later since stopping Doctor Seaweed my hair shedding is a third of what it had become. Annoying because I can’t return my unopened sealed packet and get I’ll never use it.
Be cautious!
Hi Claire,
Thank you for taking the time to share your feedback, and I’m sorry to hear about the hair shedding you experienced. I’m glad it has improved since you stopped.
Our questionnaire is intended as a simple guide only, so it doesn’t take other supplements or medication into account. We always recommend checking with your GP or pharmacist before starting any supplement, as iodine intake varies from person to person. I’ll pass your comments on to the team so we can look at how we make this clearer.
As for your unopened packet, unfortunately it falls outside our 30-day money-back guarantee, so I’m not able to process a return or refund on this occasion. I’m sorry I can’t offer more on this one.
Thank you again for letting us know, and I wish you all the best.
Kind regards,
Doctor Seaweed team
Great product and service
I recently attended the Happy Place Festival and was given some of these capsules after the period power talk. I started taking them just over a week before I was due on my period as I believe iodine can drop significantly the week before. I've experienced PMDD for years (only recently diagnosed) and this month, the week before my period I've noticed a huge positive shift in my mood. I feel like I have a bit more brain power too to take on tasks instead of procrastinating. I'm hoping things stay this way because if so, it's an absolute game changer!
Quick delivery nicely packaged will know more about the product when iv used it
Just that really- I take it daily as per instructions, am on my second packet and can feel no discernible effects.
