Think you’re getting enough vitamin B12? Think again. Even if you’re consuming animal products on the regular, you may still be missing out on this essential vitamin. That’s because not all B12 is created equal. While animal products like fish, chicken, and eggs are a great source of the vitamin, they also contain proteins called trogocytosis, which prevent the vitamin from being absorbed and used by the body. So, those animal products only serve to make you feel more full than they actually help you get the vitamin your body needs.
If you’re a vegan or vegetarian, it’s crucial to make sure you’re getting enough B12, especially since it’s so difficult for your body to store and replace.
Here are the best vitamin b12 supplements you should add to your shopping cart.

Best Vitamin B12 Supplements Buying Guide
Before choosing the best vitamin B12 supplement you should consider following options:
1. Measuring Vitamin B12 Levels: The most accurate way to measure vitamin B12 levels is by testing for methylmalonic acid (MMA), a breakdown product of vitamin B12. Unfortunately, this method is not readily available to most physicians and is costly.
An alternative method, although not as accurate, is to test for serum vitamin B12 levels. It is important to note that if the serum B12 level is low, it doesn’t necessarily mean that the cause is inadequate absorption of vitamin B12.
Other causes of low serum B12 levels include inadequate absorption and increased breakdown of B12.
2. Different Forms of Vitamin B12: Vitamin B12 comes in several forms, including cyanocobalamin and methylcobalamin.
Cyanocobalamin is the form most often found in supplements, but is the least effective. Methylcobalamin is the most effective and is the form generally used in injections.
Hydroxycobalamin is another form that is available over-the-counter, but it is not as effective as the other forms.
3. Recommended Intake of Vitamin B12: The daily recommended intake for vitamin B12, based on the Institute of Medicine, is:
1.4 micrograms for infants 0 to 6 months old
2.0 micrograms for infants 7 to 12 months old
2.4 micrograms for children 1 to 3 years old
2.8 micrograms for children 4 to 8 years old
3.0 micrograms for children 9 to 13 years old
2.6 micrograms for adolescents 14 to 18 years old
2.8 micrograms for adults 19 to 50 years old
2.8 micrograms for adults 51 to 70 years old
2.8 micrograms for adults over 70 years old
4. Measuring Vitamin B12 Status: Although measurement of serum B12 levels can be useful for some individuals, measuring MMA levels is considered the gold standard for assessing vitamin B12 status.
5. Monitoring Response to Treatment: Monitoring the response to treatment is critical. If no response is seen, the dose of vitamin B12 may need to be increased. If a response is seen and the MMA levels drop, then the dose of B12 may need to be decreased.
6. Monitoring Potential Side Effects of Vitamin B12: Although large amounts of vitamin B12 are not toxic, some individuals may develop an upset stomach, heartburn, diarrhea, or nausea, especially if taking oral forms of B12.
If an individual is taking large amounts of B12, the doctor may check their serum B12 levels periodically to ensure they are not becoming toxic.
7. Interpreting Test Results: It is important to remember that serum B12 levels, while not as accurate as MMA levels, may be more readily available to physicians.
In addition, serum B12 levels are useful for tracking response to treatment and may be more readily available to physicians.
The Takeaway on Vitamin B12: Vitamin B12 plays an important role in the health of the nervous system and in the formation of red blood cells.
Although deficiency in vitamin B12 is rare, it is important for health care providers to monitor vitamin B12 levels in individuals who are taking medications that interfere with B12 absorption, such as metformin, proton-pump inhibitors, and antacids.
