  • All-day energy: B12 is essential for turning food into cellular energy. Low levels often show up first as fatigue.
  • Sharper mind, steadier mood: Supports healthy nerve function and the brain chemistry tied to focus and mood.
  • Metabolic support with MIC: Available with methionine, inositol and choline, nutrients that support how your body processes fat.
  • Built for GLP-1 patients: Eating less can mean taking in less. A weekly dose helps cover the gap.
  • Skips the gut: Injection delivers B12 directly, bypassing the absorption issues that limit pills.

The energy vitamin, delivered the way that actually works. Vitamin B12 powers how your body makes energy, builds healthy red blood cells and keeps your nervous system sharp. But absorption from food and pills drops with age, stress, restricted eating and common medications. Kora's weekly B12 injection goes straight in, available as pure B12 or B12-MIC for added metabolic support.

  • Compounded in the U.S.A

  • Syringes and alcohol prep pads included

  • What is vitamin B12 and why does it matter?

    B12 is an essential vitamin your body can't make on its own. It plays a central role in energy production, red blood cell formation and nerve health, and levels can run low with age, diet changes and certain medications.

  • What are the potential benefits of B12 injections?

    Patients explore B12 with their provider for steadier energy, sharper focus and metabolic support. Experiences vary.

  • What is the difference between B12 pills and injections?

    Oral B12 depends on your gut to absorb it, and absorption can be limited by age, acid reducers, metformin and digestive issues. An injection bypasses the digestive system for reliable delivery.

Important safety information

Real energy. Every single week.

Our Vitamin B12 program is designed to restore steady energy, support your metabolism and keep your mind sharp, one quick weekly injection at a time.

B12 is the nutrient behind how your body turns food into fuel. When levels slip, from age, stress, a GLP-1 appetite or simply eating less, the first thing you lose is your edge. A weekly injection gets B12 where it needs to go, so you feel like yourself again.
