For some people, swallowing a daily pill is not an option, nor is it preferred, which can result in low compliance in taking supplements. While vitamin D supplements come in several other forms, such as liquids, chewable tablets, and gummies, digestive conditions such as irritable bowel disease, Crohn’s disease, or celiac disease can limit the absorption of oral vitamin D in the gut. Also, those with diseases of the liver (e.g. fatty liver) or pancreas, who have had their gallbladder removed, or who have had bariatric surgery bypassing the small intestine are more likely to have trouble absorbing or metabolizing vitamin D. For these individuals, an increased dosage or other vitamin D metabolites may be needed (please consult with your physician if this is the case).

Could Topical Vitamin D Help?

A randomized controlled trial by Bubshait et al. enrolled 550 participants, ages 18-80, with initial vitamin D levels below 30 ng/ml. The participants were split into two groups – the treatment group of 350 participants was given a topical vitamin D3 gel with 5000 IU per gram, and the control group of 200 participants was given an aloe vera gel. Participants were told to apply 1 gram of the gel daily over a 4 month period, after which vitamin D levels were re-assessed.

The treatment group began the study with an average vitamin D level of 11 ng/ml, and the control group had a starting average vitamin D level of 10 ng/ml. After 4 months of applying the topical gel, the treatment group had an average vitamin D level of 37 ng/ml, while the control group remained about the same.

As can be seen in the chart above showing the treatment group, post-treatment vitamin D levels were much greater than pre-treatment levels after using a topical vitamin D supplement for 4 months, which provided 5000 IU vitamin D through the skin. This study shows that topical vitamin D supplements may be a reliable alternative for those who either struggle with oral supplements or prefer to avoid them.
