Vitamin D Shots Vs. Oral Supplements
Vitamin D injections offer superior effectiveness compared to oral supplements, ensuring quicker and higher nutrient absorption into the body. Unlike oral intake, injections rapidly elevate vitamin D levels in the bloodstream, providing faster results. This swift response is especially advantageous for individuals with severe deficiencies or those requiring prompt elevation of vitamin D levels. When orally consumed, vitamin D becomes part of the chylomicron fraction, with approximately 80% of the dose absorbed into the lymphatics. After a single dose of 50,000 IU, the blood level of 25(OH)D typically peaks around 12 hours later. Conventional Vitamin D3 orally absorbs with an efficiency of approximately 50%.
