What is Vitamin B12 & Why It’s Important?

Your body's VIP for energy, red blood cells, and keeping your nervous system in check.

Vitamin B12 (also referred to as cobalamin) is a water-soluble vitamin that is crucial for various bodily functions, like the development of red blood cells, DNA synthesis, and even the proper operation of the nervous system. 

In contrast to other vitamins that are typically obtained from fruits and vegetables, vitamin B12 is mainly present in animal-derived foods, rendering it a nutrient many vegetarians and vegans lack, which turns them toward fortified foods and supplements.

Does Vitamin B12 Help You Lose Weight? 5 Surprising Benefits of Vitamin B12 for Weight Loss

Is Vitamin B12 the secret sauce for speeding up your metabolism, boosting energy, and keeping cravings in check?

You will probably be surprised to know that Vitamin B12 is actually one of the best hormone-balancing supplements for weight loss. Here is how Vitamin B12 helps you to lose weight: 

1. Boosting Metabolism

Vitamin B12 metabolises fatty acids and amino acids, which contribute to energy production. Having a faster metabolism aids in burning calories more efficiently, leading to weight loss.

2. Reducing Fatigue

Having low energy levels can hinder your physical activity, and if you want to lose weight, then daily exercise is important. Consuming sufficient vitamin B12 can alleviate fatigue, enabling more consistent exercise routines.

3. Aids Red Blood Cells Production

Vitamin B12 is essential for the synthesis of red blood cells, which carry oxygen throughout the body. Adequate oxygen delivery is crucial for efficient energy production and metabolism at the cellular level. When the body has sufficient oxygen, it can optimise the breakdown of carbohydrates, proteins, and fats for energy, supporting weight loss.

4. Improves Lipid Metabolism

Vitamin B12 is crucial in lipid metabolism since it converts fatty acids into energy. It acts as a coenzyme in the breakdown of fats, supporting the synthesis of succinyl-CoA, a molecule in the citric acid cycle for energy production. This makes B12 enhance the body's ability to metabolise stored fats, thereby reducing fat accumulation. Additionally, it regulates homocysteine levels, which helps reduce the risk of lipid imbalances that can cause weight gain.

5. Appetite Regulation

B12 has a positive impact on serotonin production, which can influence your appetite and mood, potentially reducing emotional eating. Some studies suggest that maintaining sufficient B12 levels may help regulate appetite, contributing to healthier eating habits and weight management.

What Happens If I Take Vitamin B12 Everyday?

Vitamin B12 has several benefits; consuming it daily can benefit your body in several ways. 

Vitamin B12 boosts the formation of red blood cells, supports nerve function and contributes to DNA synthesis. Daily intake can help you maintain stable energy levels by converting the food you eat into glucose, which is a key source of fuel for your body. 

If your B12 levels are normal, daily supplementation won't necessarily provide extra energy or boost metabolism significantly. 

If you’re worried that you might overdose on vitamin B12, then allow me to tell you that you have nothing to worry about. Vitamin B12 is water-soluble, meaning your body will excrete the excess intake through urine, so it's unlikely to cause harm even if you accidentally take a slightly higher dose. 

However, there’s a chance that extremely high doses may lead to rare side effects, like headaches or dizziness.

B12 Injections for Weight Loss: Recommended Dosage and Effectiveness

Did you know that this vitamin can also be obtained via injections? Yes! B12 injections are mostly recommended for those who are deficient in the vitamin, as its deficiency can lead to fatigue, which may hinder physical activity. 

B12 injections usually contain 1,000-1200 mg of Vitamin B12 and are administered weekly or monthly, depending on medical advice. These injections may improve energy and metabolism and even support weight loss indirectly. 

However, scientific evidence doesn’t confirm that B12 injections directly cause weight loss in individuals with normal levels of the vitamin. Overuse of injections isn’t advisable as it offers no additional benefits and could lead to unnecessary medical costs.

What Does a B12 Fat Burner Do for Weight Loss?

You’ve probably seen a B12 ‘fat burner’ supplement or injection in supplement stores marketed to boost energy, metabolism, and fat burning. 

These so-called fat burners usually combine Vitamin B12 with other ingredients like amino acids (e.g., L-carnitine) or lipotropic compounds (e.g., choline, methionine) to help boost fat metabolism. While Vitamin B12 plays a role in energy production by converting fats and carbs into energy, it doesn’t directly target fat burning. The added ingredients are believed to help break down fat more effectively, but there’s limited scientific evidence to back up these claims.

These products might support weight loss indirectly by boosting energy levels, which can lead to more physical activity. However, they're not magic pills and work best when taken alongside a balanced diet and regular exercise. It's always a good idea to consult a doctor before trying any fat burner supplements.

Dietitian’s Recommendation

As dietitians, we always say that Vitamin B12 doesn’t directly cause weight loss, but it definitely helps by boosting energy and metabolism. The best way to get enough is through a balanced diet with B12-rich foods like fish, eggs, and fortified options. If you’re low on B12 or have absorption issues, supplements or injections can help fight fatigue and make sticking to your workout routine a lot easier.
