2. Nutritional Yeast
Nutritional yeast is a popular seasoning for vegans and vegetarians, often fortified with B12. Just two tablespoons can provide over 100% of your daily requirement, making it an excellent option.
3. Supplements
For individuals who do not consume animal products and have difficulty obtaining B12, supplements might be necessary. Various forms are available, including tablets, sublingual strips, and injections.
Daily Recommended Intake of Vitamin B12
The recommended dietary allowance (RDA) for Vitamin B12 varies by age, gender, and life stage. Here’s a general breakdown:
| Age Group | Recommended Daily Allowance (mcg) |
|---|---|
| Infants (0-6 months) | 0.4 |
| Children (1-3 years) | 0.9 |
| Children (4-8 years) | 1.2 |
| Teens (9-13 years) | 1.8 |
| Adults | 2.4 |
| Pregnant Women | 2.6 |
| Lactating Women | 2.8 |
It’s crucial to monitor your B12 intake, particularly if you follow vegetarian or vegan diets.
Factors Affecting Vitamin B12 Absorption
Even if you consume adequate B12-rich foods, several factors can hinder its absorption. Understanding these factors will help you optimize your intake.
1. Age
As people age, their ability to absorb B12 diminishes. Stomach acid production decreases, making it harder to separate B12 from food proteins during digestion.
2. Gastrointestinal Health
Individuals suffering from gastrointestinal disorders, such as Crohn’s disease or celiac disease, may have difficulty absorbing B12 effectively.
3. Medications
Certain medications, including proton pump inhibitors and metformin, can interfere with B12 absorption. If you’re on medications that could affect your B12 levels, consult your healthcare provider.
