Vitamin D Spray as Good as Oral Tablets in Raising Levels


For individuals who cannot or prefer not to take oral capsules, the same increase in vitamin D levels in the blood can be achieved with a sublingual spray, suggest the results of a small UK randomized controlled trial.
Nutritionist Claire E. Williams, PhD, of the University of Sheffield, United Kingdom, and colleagues examined the ability of a daily sublingual spray to raise serum vitamin D concentrations in 75 healthy volunteers.
Working in collaboration with BetterYou Ltd, which manufactured the spray, they showed that it not only markedly and significantly increased 25(OH)D levels in comparison placebo, but the effect achieved with the spray matched that seen with a standard capsule.
Interestingly, the study results, published online last month in the European Journal of Clinical Nutrition, indicate that the participants had a slight preference for the sublingual spray.
