Probiotics may improve vitamin D absorption
Posted 6 years ago by Jacob in General Health News
New research suggests that the daily supplementation of a probiotic may boost vitamin D levels circulating in the blood by 25%. Vitamin D, known as the 'sunshine' vitamin, is responsible for the absorption of calcium and phosphate, which keep bones and teeth healthy.
A deficiency of vitamin D can cause rickets and other musculoskeletal diseases, but recent research also links vitamin D deficiency to some forms of cancer, autoimmune and infectious diseases, type 2 diabetes, and cardiovascular disease. This research has shown a positive correlation to public awareness of the health benefits of vitamin D, as many recent consumer surveys show vitamin D is consistently in the top five most popular supplements.

The new study, published in The Journal of Clinical Endocrinology & Metabolism is the first of its kind to show a link between the supplementation of a probiotic and levels of vitamin D. The study's lead author, Dr Mitchell Jones, commented:
"Although it has long been known that the gastrointestinal tract plays an active role in the absorption of vitamin D, these findings showing improved vitamin D status in response to an orally delivered probiotic are a first, and will inform the development of new products that may be beneficial for people with low vitamin D levels."
The double-blind, placebo-controlled, randomised, parallel-arm, multi-centre trial involved 127 adult participants, who were randomly assigned to either a placebo or the L. reuteri NCIMB 30242 probiotic strain for nine weeks. The results showed that the probiotic group showed significantly higher levels of vitamin D in the blood stream.
Researchers also surmised that if the probiotic strain was administered alongside a vitamin D supplement, they would see even greater increases in absorption levels. The researchers concluded, "In short, we believe it is possible that more vitamin D is being absorbed."
