The recommended daily amount of vitamin B12 for the average adult is 2.4 micrograms. [1] While your body cannot produce this vitamin, it can absorb it. You can get your daily supply of vitamin B12 through nutrient-rich foods such as dairy, fish, meat, and poultry, among other natural sources.

The easiest way to boost your B12 levels is to chart out a diet plan with the right foods. Studies have shown that people who follow a vegetarian or vegan diet are at increased risk of developing B12 deficiency. If you follow such a diet, it is recommended that you eat nutritional yeast, cereals, and other grains fortified with vitamin B12 to get your essential nutrient supply. Vitamin B12 is found naturally in several animal foods, including eggs, beef, liver, clams, sardines, salmon, tuna, trout, hard-boiled eggs, and ham. Three ounces of cooked clams contain 84.1 micrograms of vitamin B12, while three ounces of cooked salmon contains 4.8 micrograms and three ounces of light tuna fish canned in water 2.5 micrograms.

2. Supplements

Besides a healthy diet, some recommend an oral intake of vitamin B12 supplements for vegans who do not consume any meat or dairy products. [2] According to some studies, using supplements and consuming a B12 rich diet, which includes fortified cereal and milk, can help fight vitamin B12 deficiency. [3] Vitamin B12 can also be administered in the form of injections. However, this is only in cases where severe B12 deficiency is caused by anemia. [4]

How To Reverse Hair Loss Caused By B12 Deficiency?

Hair loss can occur due to several causes such as genetics, stress, hormonal changes, pollution, and excessive heat styling. The first step is to check your B12 levels to identify whether there is indeed a deficiency of the vitamin that is causing hair loss. To boost your B12 levels, consume foods that are rich in this essential vitamin. According to studies, vitamin B12, along with vitamin D and iron, is an integral part of your diet and can reduce premature greying. [5] In another study, it was found that participants reported a significant reduction in hair shedding when supplementing the diet with B12, biotin, iron, and L-Lysine. The study also identified food as the primary cause of hair shedding among women who were younger than 50. [6]

[9] Early diagnosis is critical in preventing damage.

How Much Vitamin B12 Is Too Much And What Is The Recommended Dosage?

The average daily recommended amount of Vitamin B12 differs according to your age. If you're 14 years old or older, you need to consume 2.4 micrograms of vitamin B12. Pregnant women and those breastfeeding will need a higher daily intake of 2.6 and 2.8 micrograms. [10] Although vitamin B12 intake beyond its recommended dosage does not cause much harm, there have been studies conducted, one of which shows that an elevated B12 level among pregnant women led to a higher risk of Autism Spectrum Disorder (ASD) in the child. [11] Another study conducted in the Netherlands showed that people with higher blood levels of vitamin B12 are at an increased risk of early death. [12]
