Topical vitamin D3: A randomized controlled trial (RCT).

Area of Science:

• Endocrinology
• Dermatology
• Nutritional Science

Background:

• Vitamin D deficiency is a widespread health concern.
• Traditional oral supplementation can have limitations.
• Exploring alternative delivery methods is crucial for improving patient outcomes.

Purpose of the Study:

• To evaluate the efficacy of a novel topical Vitamin D3 gel (Top-D) in increasing serum 25-hydroxyvitamin D3 (25OHD) levels.
• To assess the safety and effectiveness of the transdermal route for vitamin D delivery.

Main Methods:

• A randomized controlled trial involving 550 participants with vitamin D insufficiency/deficiency.
• The study group applied 1g of Top-D (5000 IU Vitamin D3) daily.
• The control group applied 1g of Aloe vera gel daily for 4 months.

Main Results:

• The study group showed a significant increase in mean 25OHD levels from 11.03 ng/ml to 37.17 ng/ml (p < 0.001).
• The control group's 25OHD levels remained largely unchanged (10.36 ng/ml to 10.51 ng/ml).
• The transdermal application of Top-D was well-tolerated.

Conclusions:

• Topical Vitamin D (Top-D) is a safe and effective method for increasing vitamin D levels.
• The transdermal route presents a promising alternative for vitamin D supplementation.
• This approach warrants further utilization in clinical practice.
