SIS Biotic Complex – look after your gut
SIS Biotic Complex is a once-a-day capsule to support your gut. Because hard training and big fuelling loads can stress your stomach, a healthy gut helps you absorb fuel and stay well.
So it suits riders in a heavy block or getting ready for a big event. Also, one capsule a day keeps it simple.

Who is the SIS Biotic Complex for?
It suits riders who train often and fuel hard. Take one capsule each day with food. Then give it a few weeks to settle in. Also, check the pack for the full ingredients and talk to your doctor if you have a health condition.
What’s in the box
The tub holds 30 capsules. Then one capsule is one daily serve.
A quick fuelling tip
Always test new nutrition in training before race day. So plan your carbs, fluid and salts per hour, then build that plan from drinks, gels and chews. Also, keep a note of what worked on each ride. Then on longer rides, set a reminder on your bike computer to eat and drink every 20 minutes. Because hunger shows up late, fuelling early keeps your energy steady to the finish.
