This product, in conjunction with Sea fibre-3, has become an essential daily supplement in my diet. My skin and general health has improved considerably since I started taking them. The fibre is gentle, eases IBS symptoms plus it is gluten free.
I knew from past experience with my gut, (history of Hashimotos thyroid itis ) MCAS , histamine, mold sensitivity , leaky gut etc etc .. that I should introduce the tablets slowly...I started with one a day and i was taking one a day for about 5 days and then increased the dose to only 2 a day.... my bowel did slow down for about 5 days..stool colour was lighter ? at the beginning, I went off my food and felt sluggish and felt "not hungry" but after the first week, i am feeling so much better, my bloating in my gut has reduced by 60-70% . I feel like i have much more energy (even though i have still my compounded thyroid meds) I feel more alert....I am happy to stay on the 2 a day versus the recommended 4 per day. I may increase it to see my reaction....As a teenager and young adult my naturopaths and functional medicine doctors prescribed "Kelp" tablets daily... The PhycoHealth supplements feel a lot "nicer/softer" ...thats my gut talking??:) and I am taking same dose of the seafibre3 same protocol...
Thanks so much for your in depth review Lorelei... helps us, so much, to know how you have taken on and adjusted your gut to a new space. It is indeed an ecosystem change, and therefore it will take some adjusting. But that is the point. :)
Many others will benefit know of your experience.
Best in continued health within, Lorelai.

Seafibre-Fucoidan is my new favourite supplement for digestion. This supplement settles my IBS symptoms, reduces reflux, bloating and digestive discomfort (along with healthy diet choices). I am reassured that Fucoidan is backed by research to support the microbiome and gut lining. This is now part of my longterm health regimen. Thanks to Pia and the team.
Easy to swallow, no after taste hoping for gut improvement over time!
My body loves the Seafibre. My tummy is happy and regular. Real benefits, I am certain inflammation is down and I feel lighter and more energetic.
