@gutsavi.co: Getting outside and into the sun is one of the most natural ways to support your vitamin D levels, but sun exposure is only the first step. After your skin produces vitamin D it still needs to go through a conversion process before your body can actually use it, and research suggests that certain beneficial gut bacteria are involved in that process. If your gut bacteria are low in diversity or out of balance, that conversion may be less efficient. This could help explain why some people get regular sun exposure and still show low vitamin D on blood work. Supporting your gut bacteria through a fiber rich diet and fermented foods may help your body make better use of the vitamin D your skin is already producing. If your levels are persistently low despite regular sun exposure it is worth speaking with your doctor to explore all possible causes.
