Animal-Based Sources
According to Fiona Sampat, Clinical Dietitian at Kokilaben Dhirubhai Ambani Hospital, the best natural sources of B12 include:
🐟 Seafood – Clams, tuna, salmon, sardines, and trout
🥩 Organ meats – Liver and kidneys (especially lamb)
🍗 Meat – Poultry and lean cuts
🧀 Dairy – Milk, cheese, and yoghurt
🥚 Eggs – Especially the yolks
Plant-Based and Fortified Options
For vegetarians and vegans, fortified foods are the best sources of B12:
🌾 Fortified cereals – Many breakfast cereals are enriched with B12
🌿 Nutritional yeast – Often fortified and popular among vegans
🥛 Fortified plant-based milks – Almond, soy, and oat milk often contain added B12
“For vegetarians and vegans, fortified foods and nutritional yeast are indispensable for meeting B12 needs,” says Kanikka Malhotra, consultant dietician & diabetes educator.
Tips to Enhance Vitamin B12 Absorption
1. Optimize Stomach Acid Levels
🔹 Why? Stomach acid helps release vitamin B12 from food. Low stomach acid (hypochlorhydria) can hinder absorption.
🔹 Solution: Drink diluted apple cider vinegar before meals to stimulate stomach acid production.
2. Pair Nutrients Wisely
Certain nutrients help boost B12 absorption:
✔️ Calcium – Found in dairy and leafy greens
✔️ Vitamin B9 (Folate) – Found in legumes and leafy vegetables
✔️ Vitamin B6 – Available in poultry, bananas, and fortified cereals
“Vitamin B12 absorption improves significantly when paired with calcium and folate-rich foods,” says Sampat.
3. Maintain Gut Health
A healthy gut microbiome aids in nutrient absorption.
🔹 Eat probiotic-rich foods like yoghurt, kefir, and fermented vegetables.
🔹 Consider probiotic supplements if necessary.
4. Be Cautious with Antacids
Long-term use of antacids and acid-reducing medications can impair vitamin B12 absorption. Consult a doctor if these are part of your routine.
5. Limit Alcohol Consumption
Excessive alcohol damages the stomach lining, reducing the body’s ability to absorb nutrients.
6. Consider Supplements or Injections
For older adults, vegans, or those at risk of deficiency, supplements or B12 injections may be necessary. B12 supplements are often more bioavailable than food sources.
Final Thoughts: Prioritize B12 for Better Health
Vitamin B12 is vital for energy, brain function, and overall well-being. By consuming the right foods, pairing nutrients wisely, and maintaining gut health, you can ensure optimal absorption and avoid deficiencies.
“A well-rounded diet and mindful habits are the keys to improving nutrient absorption.”
