your bottle.

Balance two carb pathways, use what is in your cupboard and get a recipe scaled to the millilitre.

Set the bottle

Water volume sets concentration; your carb target remains per bottle.

Pick a pathway ratio

Compare glucose-pathway and fructose-pathway carbohydrate equivalents.

A familiar mixed-carbohydrate option. No single ratio is best for every intake rate or rider.

Particle proxy before digestion47 comparison points

10 g/100 mL is a concentrated fuel mix. Plan fluid separately rather than assuming this bottle meets hydration needs.

Mix and test

Weigh the powder, add it to part of the water, shake until dissolved, then top up. Trial the recipe in training before using it on an important ride.

The mOsm/kg value assumes ideal dissolution and full electrolyte dissociation. Alginate and pectin are excluded. It is not a laboratory measurement or a tolerance prediction. The particle score remains a separate unitless comparison.
