Are you constantly feeling tired and sluggish?
Consider adding more Vitamin B12 to your diet. This essential vitamin plays a critical role in red blood cell production, which helps transport oxygen throughout the body. Without enough Vitamin B12, the body can’t produce sufficient red blood cells, leading to anemia.
One of the most common symptoms of anemia is fatigue, but consuming adequate amounts of Vitamin B12 can help boost your energy levels and improve your overall well-being.
This article will explore the scientific evidence behind the link between Vitamin B12 and energy and discuss how to include more of this essential vitamin through diet and injection.
Does B12 Give You Energy Right Away?
Vitamin B12 can help increase energy levels, but it may not have an immediate effect. The body needs time to absorb and utilize the vitamin, so it may take a few days for an individual to notice a change in energy levels.
If an individual is deficient in Vitamin B12, it may take longer to experience an increase in energy once they begin supplementing with the vitamin orally or through B12 injection.
An increase in energy is just one of the many potential benefits of Vitamin B12, and everyone may experience different results.
Signs of B12 Deficiency
About 6% of people under 60, and 20% of people over 60 in the US, have a deficiency in Vitamin B12. Here are some significant signs of B12 deficiency.
- Fatigue
- Dizziness
- Weakness
- Depression
- Weight loss
- Irregular heartbeat
- Shortness of breath
- Tingling in hands and feet
How Much B12 Should I Take For Energy
According to the NIH Office of Dietary Supplements (ODS), the recommended daily intake of Vitamin B12 for adults is 2.4 micrograms (mcg). However, the amount of Vitamin B12 an individual, should take for energy depends on several factors, such as age, dietary habits, and underlying health conditions.
Should You Take B6 or B12 For Energy?
Vitamin B6 and Vitamin B12 play essential roles in the body, including energy metabolism. However, they have different functions and deficiency symptoms.
Vitamin B6, also known as pyridoxine, helps the body make the hormones serotonin and norepinephrine, which regulate mood and help the body cope with stress. It also helps the body make red blood cells and also helps the body to convert food into energy.
On the other hand, Vitamin B12 plays a critical role in producing red blood cells, which helps transport oxygen throughout the body. A deficiency in Vitamin B12 can lead to anemia, a condition without enough red blood cells to carry oxygen to the body’s tissues. This can cause fatigue and weakness.
Which Other Vitamins and Minerals are Best For Energy?
Vitamin C: This vitamin acts as an antioxidant, helping to protect cells from damage and supporting the immune system.
Vitamin D: This vitamin helps the body to absorb calcium and phosphorous, which are essential for healthy bones and teeth.
Iron: Iron is important for producing hemoglobin, a protein in red blood cells that helps transport oxygen throughout the body. An iron deficiency can lead to anemia and cause fatigue, weakness, and other symptoms.
Does Vitamin B12 Injection Helps In Vitamin B Deficiency And Anemia
Vitamin B12 injections (Cyanocobalamin and Methylcobalamin) can be an effective treatment for individuals with a deficiency in Vitamin B12 and anemia caused by low levels of this vitamin.
Injections of Vitamin B12 can be given in a doctor’s office or clinic and are usually administered into a muscle. They may be given as a single dose or multiple doses over time. The dosage and frequency of injections will depend on the individual’s needs and deficiency level.
Vitamin B12 Injections Dosage And Frequency For Anemia
For pernicious anemia, a condition in which the body cannot absorb Vitamin B12 from food, the usual dosage is
- 100 mcg given intramuscularly daily for one week
- 100 mcg every other day for seven doses
- 100 mcg for every 3 to 4 days for the next 2 to 3 weeks
- The monthly maintenance dose will be 10 to 100 mcg for life.
It’s essential to monitor serum potassium closely during the first 48 hours of treatment and replace potassium if needed.
Who Needs B12 Injections?
Some people who may need Vitamin B12 injections include:
- Vegetarians and vegans may not consume enough Vitamin B12 in their diet.
- Individuals who have had weight-loss surgery, as surgery can affect the absorption of Vitamin B12.
- Individuals with certain medical conditions such as Crohn’s disease, celiac disease, and certain types of cancer can affect the absorption of Vitamin B12.
- Individuals take certain medications that can interfere with the absorption of Vitamin B12, such as metformin, proton pump inhibitors, and H2 receptor antagonists.
- In older adults, the ability to absorb Vitamin B12 decreases with age.
Vitamin B12 Injection Side Effects
The most common side effects of Vitamin B12 injections are:
- Pain or discomfort at the injection site
- Swelling or redness at the injection site
- Itching
- Headache
- Fatigue
- Nausea
These side effects are usually mild and short-lived.
Which Foods Are Rich In Vitamin B12?
Vitamin B12 is found naturally in a variety of animal-based foods, including:
-
- Meat: beef, pork, lamb, and organ meats such as liver and kidney
- Fish and seafood: salmon, tuna, haddock, and sardines
- Dairy products: milk, cheese, and yogurt
- Eggs
Vegans and vegetarians have a higher risk of developing Vitamin B12 deficiency, as Vitamin B12 is mostly found in animal-based foods. However, some plant-based foods are fortified with Vitamin B12, such as:
- Nutritional yeast
- Fortified breakfast cereals
- Fortified plant-based milk alternatives (soy, almond, rice)
- Fortified tofu
- Fortified nutritional bars
The bioavailability of Vitamin B12 from plant-based sources is not as good as that from animal-based sources, and it may not be enough to meet the daily requirements.
Therefore, vegans and vegetarians who don’t consume any animal products may need to consider taking Vitamin B12 supplements or fortified foods to meet their daily needs.
Final Words
Vitamin B12 can help increase energy levels; it is not a substitute for other healthy lifestyle choices such as regular exercise and a balanced diet.
