When it comes to weight loss, most people think about diet, exercise, and perhaps medications. But there’s a lesser-known player in the energy and metabolism game, vitamin B12. At Hodgson Pharmacy in Longfield, we’re seeing more interest from patients asking, “Does B12 help with weight loss?” and “Where can I get B12 injections near me?”

In this blog, we’ll explore the role of vitamin B12 in weight management, how it supports your body’s energy systems, and how our pharmacy integrates B12 assessments and injections into our structured weight loss services.

What Is Vitamin B12 and Why Is It Important?

Vitamin B12 (also known as cobalamin) is an essential vitamin that your body needs but cannot produce on its own. It plays a vital role in:

  • Energy production
  • Red blood cell formation
  • DNA synthesis
  • Nerve function
  • Metabolism of fats and proteins

If you’re lacking in B12, you may experience fatigue, weakness, brain fog, or difficulty losing weight, even if you’re doing all the right things.

Vitamin B12 and Its Link to Weight Loss

Does B12 Help with Weight Loss?

While B12 is not a “magic shot” for weight loss, it can help in indirect but meaningful ways. It supports:

  • Increased energy levels – making it easier to stay active
  • Improved metabolism – helping your body convert food into usable energy
  • Enhanced mood and motivation – which are key when sticking to a weight loss plan

Deficiency in B12 can slow down your progress, even if your diet and exercise are on point.

Who Is at Risk of B12 Deficiency?

Vitamin B12 is naturally found in animal products like meat, fish, dairy, and eggs. You may be at risk of deficiency if you:

  • Follow a vegetarian or vegan diet
  • Have digestive issues like Crohn’s, IBS, or coeliac disease
  • Are over 50 years old (absorption decreases with age)
  • Take medications like metformin or proton pump inhibitors (PPIs)
  • Have undergone weight-loss surgery

At Hodgson Pharmacy, we offer vitamin B12 deficiency assessments to help determine if B12 supplementation could benefit your weight loss plan.
