Dosage is another key factor. While the recommended daily allowance is much lower, higher doses like 5000 mcg are often used to correct deficiencies or support energy levels, particularly in older adults or those on plant-based diets. Always consult with a healthcare provider to determine the right dose for your needs.

Sublingual drops offer superior absorption compared to oral tablets, as they bypass the digestive system.
