Is Liquid Death Flavored Sparkling Water low FODMAP?

FODMAP score

Moderate

Mostly yes, with one asterisk — the flavored line (Severed Lime, Mango Chainsaw, Berry It Alive) is sweetened with agave nectar, a fructose-dominant sweetener that is a known FODMAP flag even in small doses. The saving grace is quantity: about 3g of sugar per tallboy, a far smaller fructose load than juice or soda. The plain Mountain Water cans have no sweetener at all and are simply water.

What's inside

Agave nectarRoughly three-quarters fructose with little glucose to balance it — the small ~3g dose keeps the load modest but real.

Carbonated mountain waterNot a FODMAP, but the CO2 itself can leave sensitive stomachs feeling gassy and distended.

Natural fruit flavors and extractsFlavor-level amounts of lime, mango, or berry extracts carry negligible sugars.

Citric acidAn acidulant, not a fermentable carbohydrate.

📏 One 16.9oz tallboy carries about 3g of sugar from agave — small in absolute terms, but nearly all of it is excess fructose, and multiple cans stack the dose.

Gentler alternatives

↳Unsweetened essence-flavored seltzers — Citrus or berry aroma with no agave and no sugar of any kind.

↳Still water with fresh-squeezed lime — Skips both the agave and the carbonation if bubbles alone bother you.
