Vitamin B12 serves a vital function in nervous system health, red blood cell development, and DNA synthesis. Uniquely, the body cannot make cobalamin, thus it must be supplied through diet or supplementation.
Choosing between vitamin B12 from foods or supplements like tablets or b12 vitamin tablets is a common conundrum. To help you choose the best vitamin B12 supplement or dietary source, this guide compares their pros and cons.
Importance
It promotes red blood cell synthesis and prevents anaemia, which causes weariness and weakness. Beyond blood health, vitamin B12 helps produce myelin, the protective covering around nerves, ensuring nerve cell communication. Reducing nerve damage, cognitive decline, and mood swings requires this function. Vitamin B12 helps cells grow, mend, and divide by synthesising DNA, which is essential for vitality. By regulating homocysteine levels, the vitamin helps heart health.
What are the Symptoms of Vitamin B12 Deficiency?
B12 insufficiency causes many symptoms. Low vitamin B12 levels have five symptoms:
- Low Energy: Since B12 insufficiency reduces oxygen-carrying red blood cells, fatigue and weakness may occur.
- Alterations in the brain: B12 deficiency can cause hand and foot tingling, cognitive loss, and mood swings.
- Juvenile Skin: B12 deficient anaemia can stain skin pale or yellow.
- Toothaches, glossitis: The tongue's inflammation and discomfort often indicate insufficient B12.
- Poor Vision: B12 deficiency can damage optic nerves, blurring vision sometimes.

Here's a closer look at the top five vitamin B12 foods and their B12 content, great for naturally maintaining vitamin B12 levels:
Eggs
Eggs are a great vitamin B12 source for breakfast, lunch, and dinner. Large eggs contain 0.6 micrograms of vitamin B12, making them an easy option to increase intake. B12 is highest in the yolk, so eat the whole egg to get the most. B2 (riboflavin) and B5 (pantothenic acid) are also found in eggs, which help energy metabolism and cell health. Its ingredients make eggs great for energy, cognitive health, and cellular repair.
Clums and Mussels
Clambakes and mussels have the greatest vitamin B12 content of any cuisine. In a 3-ounce (85-gram) serving of clams, vitamin B12 contains 84 micrograms, or 3,500% of the DV. Mussels give 20 micrograms per 3-ounce serving, making them good sources. Shellfish contain the B12, protein, iron, and omega-3 fatty acids that support cardiac, cognitive, and muscle health. Shellfish like clams and mussels are great for B12 deficiency or rapid B12 boosts due to their powerful nutritional profile.
Salmon, Trout & Tuna
Flavorful salmon, trout, and tuna are rich in vitamin B12 and omega-3 fatty acids, which support heart and brain function. Trout has 5.4 micrograms of vitamin B12 per 3-ounce serving, while cooked salmon has 4.9 micrograms (200% of the DV). At 2.5 micrograms per 3-ounce serving, canned light tuna is rich in B12. Combining B12 and omega-3s, these fish reduce inflammation, improve mood, and boost cognition. A diet rich in fatty fish two to three times a week can boost vitamin B12 and other health-promoting elements.
Cheese, Yogurt, and Milk
Those who eat dairy regularly will benefit from vitamin B12 in milk, cheese, and yogurt. A cup of whole milk has 1.2 micrograms of vitamin B12 (50%) while an ounce of Swiss cheese has 0.9. A cup of plain Greek yogurt has 1.3 micrograms. Milk contains B12, calcium, phosphorus, and vitamin D, which strengthen bone, muscle, and immunity. Dairy products provide a stable and convenient source of vitamin B12 for vegetarians on a daily basis.

Plant-based meals lack vitamin B12, hence fortified cereals are useful for vegetarians and vegans. Many cereal makers add B12 to assist vegans satisfy their nutritional needs. Morning cereal provides 1.5 to 6 micrograms of vitamin B12, which can meet or surpass the daily need.
