Quizplus · Accepted Answer

Sunscreen with an SPF of 8 or higher can reduce vitamin D synthesis. It is important to balance the need for sun protection with the need for vitamin D production. It is recommended to get vitamin D from food sources such as fatty fish and fortified dairy products, or to take a supplement if necessary.
