Most of us are Vitamin D deficient. We do not spend enough time in direct sunlight for an hour with all our limbs exposed. I've been taking 5000 IU for last 10 years to maintain ~55 ng/mL after finding out I was dangerously low at 12 ng/mL. And I used to live in Australia, the land of constant sunshine. I avoid listening to the FDA recommended dose which has historically been increasing every few years. Just get your blood work done and supplement to maintain around ~ 55 ng/mL. That's better than listening to generic advice. Btw. This pissed me off when BlueShield few years ago stopped covering Vitamin D blood tests because of this nonsense: Most People Don't Need Vitamin D Testing https://www.bcbs.com/news/press-releases/most-people-dont-need-vitamin-d-testing https://www.bcbs.com/news/press-releases/most-people-dont-ne... "The U.S. Preventive Services Task Force recently found the current medical evidence insufficient to assess the balance of benefits and harms of screening for vitamin D deficiency in asymptomatic adults." "The American Society of Clinical Pathology contributed the following recommendation to Choosing Wisely®, “Many people have low levels of vitamin D, but few have seriously low levels. Most of us don’t need a vitamin D test. We just need to make simple changes so we get enough vitamin D.”"
