Tag: B12 dosage

The Recommended Dietary Allowance (RDA) for vitamin B12 for most adults is only 2.4 mcg, yet many supplements contain 1000 mcg or more. The question of whether **is 1000 mcg of B12 per day too much** requires understanding the complex absorption process rather than just comparing the numbers.

Before considering the appropriate dosage of B12 supplements, consult with a healthcare provider. While the recommended dietary allowance (RDA) for vitamin B12 for adults is just 2.4 mcg per day, supplements often contain much higher amounts. This raises the common question: "Should I take 500 mcg or 1000 mcg B12?" The answer depends on your individual health status, your reason for supplementation, and your body's ability to absorb the vitamin.

Approximately 6% of adults under age 60 in the United States have a vitamin B12 deficiency [1.9.4]. If you're supplementing, you might wonder, can you take two B12 at the same time safely? Generally, yes, but understanding the details is key.
