The vitamin is absorbed in two ways: Active through a special transport molecule (intrinsic factor) saturated at approximately 1.5g per dose/meal Passive through vitamin B12 that passes through the intestinal wall without a transport molecule maximum 1% of the supplied dosage The real intake is calculated through the combination of these two mechanisms
Tablets just as effective Over-the-counter B12 tablets are a fraction of the cost of shots, and have been shown in a British-Canadian study to work just as well for most people, although some people with digestive conditions may have difficulty absorbing the vitamin in tablet form
