Many people may not get enough vitamin D from sunlight and food sources alone. Vitamin D is naturally produced when your skin is exposed to sunlight, but factors like limited sun exposure, geographic location, season, skin tone, age, and sunscreen use can affect how much your body makes. While some foods contain vitamin D, there are relatively few dietary sources that provide significant amounts. A vitamin D3 supplement can help ensure you're getting adequate levels of this important nutrient to support your overall health and well-being as part of a balanced diet and healthy lifestyle.*
