Vitamin D3 has many functions for humans that include keeping bone health normal, maintaining the immune system function, and improving the energy levels of the human body. Lower levels of vitamin D are observed in many people especially those who have very little or no sun exposure. For that reason, vitamin D deficiency is very common in cooler countries such as Canada and Western Europe.
Vitamin D deficiency can present in many ways such as fatigue, weakness, poor physical performance, low immunity, and frequent infections such as colds and flu. When vitamin D deficiency is persistent for many years and the immune system is so down, the patients may develop cancer or if they have cancer, it is usually in the advanced stages.
This article, Vitamin D 3 injections Scientific Research focuses on the best route of administration of vitamin D for people who are deficient in vitamin D.
This research was published in the Indian Journal of Endocrinology and Metabolism in 2017. The researchers compared patients with low vitamin D in their blood who were given either oral vitamin D supplements or intramuscular injections of the Vitamin D. At the end of the study, both groups were compared regarding the vitamin D level in their blood as well as the maintenance of this level after many weeks of the administration.
After the study ended, the researchers found that patients who had their vitamin D as a supplement (given orally) attained an adequate level of vitamin D in their blood, however, they did not retain this level for a long time, so they needed a longer administration of the vitamin D supplement as compared to those who had the vitamin D in the injection form, who were able to achieve the adequate level of the vitamin D and retained it for a longer time as compared to the supplement’s group.
