Advancing hypo recovery for people living with type 1 diabetes.

Standard glucose corrects the low. It doesn't treat what comes after — the brain fog, fatigue, and repeat episodes that disrupt your patients' lives for hours.

Klario Energy hypo recovery drink — bottle and poured glass

The unmet need

Hypoglycemia remains a frequent and feared complication of diabetes treatment.

For many people with type 1 diabetes, hypoglycemia is not an occasional event — it is a repeated disruption to daily life.

Standard glucose-only options reliably correct blood sugar but often fail to deliver full functional recovery. Many suffer rebound highs, recurrent lows, and a lingering hypo "hangover" even after glucose levels have normalized.

The MESH™ approach

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 during the post-hypo recovery period.

Clinical Trial Results

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

An independent randomized controlled crossover study in adults with type 1 diabetes, using continuous glucose monitoring (CGM) and patient-reported outcomes in a real-world setting, comparing Klario directly against standard of care glucose gel.

The science behind Klario

Studies show that cognitive function, including thinking, attention and reaction time, can remain impaired for some time after blood glucose has been corrected.

This suggests that restoring glucose in the bloodstream does not immediately restore energy supply within brain cells, potentially due to a hypothesized “brain energy bottleneck.”

Alternative energy sources such as BHB and lactate may help by entering the brain’s energy-producing pathways through routes that do not depend on the same step in glucose metabolism.

Providing these substrates alongside glucose may therefore support energy production while normal glucose use recovers.

This is the scientific rationale behind novel nutritional approaches based on multi-energy substrates for hypoglycemia (MESH).
