Advancing hypo recovery for people living with type 1 diabetes

Klario is a first-in-class hypo recovery drink combining glucose with BHB to help people feel and function better after low blood sugar.

Klario Energy hypo recovery drink — bottle and poured glass

Hypoglycemia remains a frequent and feared complication

For many people with type 1 diabetes, hypos are not occasional events — they are repeated disruptions to daily life. Standard glucose-only treatments correct blood sugar but leave many patients with rebound highs, recurrent lows, and a lingering hypo 'hangover.'

A different approach to hypoglycemia recovery

Klario® is a novel recovery drink that combines 15g of fast‑acting carbohydrate with adaptive energy sources - beta‑hydroxybutyrate and lactate.

Its proprietary multi-substrate system, MESH™, was designed to support rapid blood glucose correction and sustained brain energy recovery after a hypo.

Proven in a 12-week randomized crossover study in adults with T1D

Klario is validated through two randomized clinical studies, analyzing more than 1,000 real-world hypoglycemic episodes.

CGM DATA

Klario was associated with higher post‑hypoglycemia Time‑in‑Range and fewer recurrent episodes versus participants' usual glucose‑only products.

27%
Reduced risk of a recurrent hypo following treatment vs standard of care
↑ TIR
Improved time-in-range in the 2 hours following a treated hypo vs standard of care

Beyond glucose: bypassing the brain energy bottleneck

Evidence shows that during and after a hypo, the brain's ability to convert glucose into usable energy can be temporarily impaired.

This 'bottleneck' can mean that even once blood sugar is corrected, energy supply to neurons may still lag.

The human brain can efficiently utilize alternative energy sources like beta-hydroxybutyrate and lactate, particularly during glucose scarcity.

These follow different metabolic pathways, bypassing the energy bottleneck and delivering an efficient energy supply to the brain.

Applying multi-energy substrates for hypoglycemia (MESH™) approaches may help restore blood glucose and brain energy.

A scientific advisory board at the forefront of diabetes care

Klario's MESH™ formula and research program have been developed in collaboration with leading clinicians and researchers in diabetes, metabolic medicine, and exercise physiology.
