Great product - initially the flavour was a little off putting, but you used to it quickly.

Great Fibre Support for My Needs

These have been a great support for my fibre intake, especially with my high-protein diet and post-menopausal needs. I feel good taking them and notice the difference.

Yes, they can repeat on me a little and make me a bit windy at times — but that actually seems like part of the digestive benefits kicking in! 😄 For me, it’s been a positive trade-off.

Seaweed fibre Tablets

Brilliant. These really help gut health, you can notice it very quickly. they have a bit of an after taste, but that goes away if you take them with food and good drink.
