Dr. Mark Hyman: 维生素D对健康至关重要，它对情绪、能量、甲状腺功能、癌症预防、免疫功能以及预防感染（包括COVID-19）都有积极作用。然而，大多数美国人都缺乏维生素D，这可能是由于现代生活方式导致的日晒不足和营养缺乏。维生素D缺乏与多种疾病有关，包括骨质疏松症、抑郁症、癌症、高血压、心脏病、糖尿病、纤维肌痛和自身免疫性疾病等。为了获得最佳的健康益处，应将维生素D水平维持在45-75纳克/毫升之间。这可以通过阳光照射、饮食和补充剂来实现。建议服用维生素D3，而非维生素D2。最佳摄入量因人而异，取决于年龄、基因、居住地、日晒时间和季节等因素。建议定期检查维生素D水平，并根据自身情况调整补充剂量。此外，还应注意防晒霜的选择，避免使用含有有害成分的防晒霜。
