Beyond glucose: bypass the bottleneck

A new way to recover from hypos — combining fast carbs with adaptive energy for complete recovery

A new approach

Klario is designed to bypass the brain’s energy bottleneck using adaptive energy with fast carbs

Built and proven by experts

Developed by leading diabetes specialists and studied across 1000+ real-world hypos

Achieving complete recovery

In studies: Klario delivered 27% fewer recurrent hypos and got 75% back to their day faster

CGM tested in real world hypos

Klario has been studied in a randomized clinical study of more than 1,000 self‑treated hypos in adults with type 1 diabetes

  • klario led to 27% fewer recurrent hypos

    fewer repeat lows in the 2 hours after treating a hypo

  • klario led to 10 fewer days in glucose lows and highs over one year

    fewer days in glucose highs and lows over a year

  • Analysis showed:

    • Fewer repeat lows after a hypo, with more time in range in the 2 hours following treatment
    • Less time spent in glucose extremes, adding up to 10 days in total over 1 year

Proven to get your day back faster

Real-world improvements in how people feel and function after a hypo with Klario

“I usually have a crash pattern where you go up and down all day — I haven’t had that with Klario.”

Julia, clinical trial participant

"The fatigue and brain fog definitely improved. It made a huge difference at work; I could actually go about my day instead of being written off."

Thomas, clinical trial participant

How Klario feels in everyday life

Beyond numbers on a graph, people in the study told us Klario helped them feel and function better after a hypo

The problem: an energy bottleneck

During a hypo, your brain runs low on its usual fuel—glucose. Even after levels return to normal, it may struggle to use that glucose efficiently, creating an ‘energy bottleneck’ that can leave you feeling wiped out and foggy.

How Klario works

  • Icon showing 15g of fast-acting carbohydrates in Klario to raise blood sugar levels.

    Corrects glucose

    Klario contains 15g of fast‑acting carbohydrate to raise blood sugar, just like standard treatments

  • Illustration of the human brain utilizing adaptive energy pathways for alternative fuel when glucose is low

    Adds adaptive energy

    It also provides adaptive energy that the brain can use through different pathways when glucose use is limited

  • Icon representing a person experiencing clarity and a lift in brain fog after using Klario for hypo recovery.

    Supports clearer recovery

    Bypassing the energy bottleneck, Klario fuels the brain directly, helping reduce brain fog and the “hypo hangover”

What is adaptive energy?

Your body’s built-in backup fuel system—activated when glucose runs low, helping keep your brain and body functioning.

BHB is one example. Produced by the liver, it rises during fasting, or intense exercise—and provides an additional energy source when glucose alone isn’t enough.

Clinically proven. Mechanism-driven.

Klario is built on rigorous clinical research, combining fast-acting carbohydrates with adaptive energy to support more complete recovery after hypoglycaemia.

Our studies explore objective CGM data, real-world outcomes and underlying metabolic mechanisms — helping explain not just that Klario works, but why.
