How B12 Injections Affect Your Metabolism
Feeling sluggish or defeated in your weight loss efforts? Supercharge your energy, fire up your metabolism, and crush your weight goals with B12 injections. Here’s how it works.

Have you been struggling with slow weight loss or low energy? Dr. Hughan Frederick at Glow Anti-Aging Center and Medical Spa in Roswell, Georgia, has a solution that might just change the game for you. 

B12 injections have gained popularity for boosting metabolism, increasing energy, and supporting weight management. But how exactly do they work, and could they fit into your weight loss plan? Here’s what you need to know. 

What are B12 injections?

B12 is an essential water-soluble vitamin, also known as cobalamin, responsible for critical functions like red blood cell formation, brain health, and DNA synthesis. Found naturally in animal-based foods such as fish, eggs, and dairy, B12 converts food into energy by helping your body metabolize or use carbohydrates, fats, and proteins. 

For those who might not be getting enough B12 through their diet — vegans, vegetarians, or people with absorption issues — B12 injections deliver fast-acting and bioavailable nutrients directly into the bloodstream. 

At Glow Anti-Aging Center and Medical Spa, B12 injections are a core part of our weight management program designed to help you lose weight safely and efficiently. 

The connection between B12 and your metabolism

The process by which your body turns food into energy is metabolism, and a healthy metabolism helps your body burn calories, even at rest. 

Adequate levels of B12 support metabolism in three key ways:

1. Energy production

B12 breaks down nutrients from food and turns them into usable energy. If you’re low on B12, you may feel fatigued and sluggish.

2. Fat metabolism

Research shows that low B12 could influence fat metabolism because a lack of B12 may hinder your body’s ability to burn fat effectively, potentially leading to weight gain.

3. Preventing anemia

One of the jobs of B12 is to help produce healthy red blood cells, which carry oxygen throughout your body. Low oxygen delivery can slow down metabolic functions, making it harder for your body to burn calories. 

Though B12 injections won’t directly “melt the pounds away,” they will create an environment in which your body can perform at its best. That’s why we encourage you to pair B12 therapy with smart lifestyle changes for optimal results. 

How B12 injections fit into our weight loss program

At Glow Anti-Aging Center, B12 injections are part of a holistic weight management approach. We combine them with other strategies like personalized nutrition advice, hormone balancing, and prescription medications. Here’s how these injections can help you lose weight when paired with the right plan: 

1. Higher energy 

When energy levels are high, you’re more likely to stay active throughout the day and have more motivation to hit the gym or simply move your body. 

2. Better calorie burn 

The better your metabolism, the better your body burns calories — even when you’re just relaxing. 

3. Addressing deficiencies 

Some people struggle with weight loss because of underlying B12 deficiencies caused by diet or absorption issues. B12 injections solve this problem quickly. 

4. Appetite and mood regulation 

Although this isn’t a direct effect of B12, improving energy and well-being can lead to better appetite control and fewer emotional eating episodes. 

Who benefits most from B12 injections?

Though vitamin B12 shots can benefit anyone looking to boost their energy or metabolism, certain groups are more likely to see dramatic improvements:

  • Vegans and vegetarians: Plant-based diets are more likely to result in B12 deficiencies
  • Older adults: Aging may affect your body’s ability to absorb B12 from food 
  • People who don’t absorb B12 well: due to Crohn’s disease or medications

Also, anyone on a weight loss plan can benefit from B12. If a sluggish metabolism is holding you back, consider B12 shots to complement your other weight management strategies.
