What Is Cyanocobalamin?

Cyanocobalamin is a synthetic form of vitamin B12, essential for:

  • Red blood cell formation
  • DNA synthesis
  • Energy production
  • Nervous system function

Low B12 levels are common in people with gastrointestinal issues or restrictive diets. Some research suggests that vitamin B12 may also play a role in alleviating fatigue by acting as a nitric oxide scavenger.

Potential Benefits of having Cyanocobalamin with Semaglutide

  • Energy Support: B12 is vital for energy production in cells, and supplementation may help address fatigue during weight loss.
  • Neurological Health: Supports nerve health, especially in diabetic patients at risk for neuropathy.
  • Metabolic Balance: While B12 doesn't directly promote weight loss, it supports overall metabolic function.
  • Adherence Support: Patients feeling less fatigued are more likely to continue healthy behaviors.

Emerging data from real-world studies suggest that this combination may improve body composition and treatment adherence.

How This Combination Is Typically Administered

Many clinics administer weekly injections combining semaglutide and cyanocobalamin.

Typical Dosing:

  • Semaglutide: Starts at 0.25 mg and titrates up to 2.4 mg weekly.
  • Cyanocobalamin: Often 750–1,000 mcg weekly, tailored to lab values and patient needs.

Always follow your provider’s guidance, as doses and schedules vary by individual. 

Safety and Side Effects

Semaglutide:

  • Common: Nausea, fatigue, constipation, injection site reactions
  • Rare: Pancreatitis, gallbladder disease, thyroid tumors in predisposed individuals

Cyanocobalamin:

  • Generally safe

Both are well-tolerated when used as prescribed, but regular monitoring is advised.

Who Might Be a Good Candidate?

This combination may benefit those who:

  • Are eligible for GLP-1 treatment
  • Show signs of B12 deficiency
  • Experience fatigue during weight loss
  • Commit to supervised, long-term lifestyle changes

Your provider will evaluate lab markers, diet, and medical history before recommending this regimen.
