According to a systematic review published in 2021, vegans were found to have lower levels of vitamin D and were at a higher risk of deficiency compared to non-vegans, highlighting a key nutritional challenge. This occurs because many common forms of vitamin D are not inherently suitable for vegans, primarily due to their animal-based origins.

Recent meta-analyses suggest that vitamin D3 is superior to vitamin D2 in raising and maintaining overall vitamin D blood levels, a critical factor for bone and immune health. While both forms are effective, their differences in potency and source are important considerations. So, **is D2 or D3 better** for your specific nutritional needs? The answer depends on several key factors related to absorption, metabolism, and dietary restrictions.

Studies consistently indicate that vitamin D3 is significantly more effective at raising blood vitamin D levels and sustaining them over time compared to D2. This guide explores which is the best vitamin D supplement D2 or D3, examining their sources, efficacy, and suitability for different dietary needs.
