Help maintain a healthy thyroid with Lewtress Kelp.

Kelp (Bladderwrack)

Kelp, otherwise known as Bladderwrack, has been used for hundreds of years as a rich source of natural vitamins, minerals and iodine. It is hard to believe that this nourishing seaweed, sourced from the bluest of oceans, can help with many ailments. Kelp is a rich source of iodine, enabling the production of the hormone, Thyroxin. Thyroxin helps maintain a healthily functioning thyroid gland, a healthy thyroid means an improved metabolism and increased energy levels, deterring problems such as excessive weight gain and obesity. Kelp is therefore an integral part of any diet or weight control regime. Kelp may also be useful in aiding conditions such as asthma, eczema, morning sickness, water retention, constipation and nervous disorders.

Customer Stories

“It may be of interest to you to know that within 4 days of taking your kelp I started to lose weight (4.5kilos to date see previous e mail no loss in the previous six months on a starvation diet). Further I tested myself for an iodine inbalance ( placing a ring of tincture of iodine on the back of the hand this was absorbed within 20 mins… 4 hours would be a normal rate) it is now normal! My T4 levels have increased by 7 ( pre kelp T4 was 22.00 it is now 29.00) I feel great, have more energy but hey ho the medics tell me I am now over medicated and have decreased my thyroxine from 100 mgs to 75 mgs! …the medic concerned nearly had a seizure when kelp was mentioned however until he can suggest something better I will continue to use it.” – ST
“Further to my previous e mail keeping you update with my progress…I see my last one is now on your web…well: Since my last update I have continued to lose weight at a really good rate and have now lost in total a massive 12.5kilos more importantly I feel great with much more energy and a clearer mind..despite the medics reducing my thyroxine I have continued to lose all the related symptoms of having an underactive thyroid gland brought on by radio active iodine to correct an overactive thyroid. May I also say that the only time I have gained weight is when I failed to take kelp daily due to running out of it!” – ST

I have been buying products from Lewtress for many years. The experience has always been first rate. The purchasing process couldn't be simpler and they dispatch stuff quickly, usually on the day of purchase and it arrives the next day. Who could ask for more? One very happy customer 😉👍


I am using Bombyx daily complex and can confirm that is the best daily supplement I have used to help any ED problems. I also use Bombyx Mori L complex when help is needed. This is again the very best. Thank you Lewtress for your help and advice.

Lewtress offers a quick, discreet service with some Aphrodisiacs that have really worked for me over the years. The one I currently use is Bombyx Mori.
