Why this certification matters
- Informed Sport
- Informed Sport certification is especially relevant for athletes in tested sports because products are batch-tested for substances prohibited in sport.
Frequently asked questions
- What's the active ingredient?
- The Bimuno galacto-oligosaccharide (GOS) — a non-digestible prebiotic fibre that reaches the colon and feeds beneficial bacteria such as bifidobacteria. GutSupp is the rebrand of the product formerly sold as Bimuno.
- Is it dairy-free?
- No. The GOS is derived from lactose (milk), so it isn't suitable for those avoiding dairy. The finished powder is tasteless and dissolves into hot or cold food and drink.
- How do I take it?
- One sachet daily, stirred into any cold or room-temperature food or drink — coffee, smoothies, yoghurt or water. It's heat-stable and unflavoured.
- Is it certified for banned substances?
- Yes — Informed Sport, with each batch screened against the WADA banned list. That's uncommon for a prebiotic and useful for tested athletes.
- How is a prebiotic different from a probiotic?
- A prebiotic is fibre that feeds the bacteria already in your gut; a probiotic supplies live bacteria. GutSupp is a prebiotic — it nourishes your existing bifidobacteria rather than adding new strains.
