Frequently Asked Questions

What makes Sunfiber different from other prebiotic supplements?

Sunfiber (PHGG) is unique because it is completely water-soluble, tasteless, odourless, and does not cause gas or bloating — common side effects of other fibre supplements like inulin or FOS. It is also clinically studied for both constipation and diarrhoea, making it suitable for IBS and general gut health.

How do I take Biosphere Sunfiber?

Mix the recommended serve (per label instructions) into water, juice, coffee, smoothies, or food. It dissolves completely without changing the taste, colour, or texture of the drink or food.

Can Sunfiber help with IBS?

Yes. Sunfiber has been clinically studied in IBS and shown to help normalise bowel function — reducing diarrhoea in IBS-D and improving constipation in IBS-C. Its gentle, non-gas-producing nature makes it suitable where other fibres cannot be tolerated.

How long does it take for Sunfiber to work?

Many people notice improved bowel regularity within 1–2 weeks. For microbiome and immune benefits, consistent use over 4–8 weeks is recommended.

Is Biosphere Sunfiber suitable for diabetics?

Yes. Sunfiber is low GI and has been shown to slow glucose absorption, helping to moderate blood sugar spikes after meals. It is a suitable fibre supplement for people managing blood sugar, including those with type 2 diabetes.
