Mindsip insights from this episode:

Avoid mega-dosing vitamin D to prevent toxicity and high calcium levels

Mega-dosing vitamin D can cause toxicity by increasing calcium absorption, leading to high blood calcium, kidney stones, and in extreme cases, renal failure.

Supplement vitamin D to lower diabetes risk for deficient individuals

One study found a 62% lower rate of diabetes among participants who started with low vitamin D levels and then took supplements, suggesting a targeted benefit for deficiency.

Recognize vitamin D as a marker of healthy lifestyle choices

Good vitamin D levels are often a marker of a healthy lifestyle, not the cause of good health, similar to how wearing a helmet doesn't make you a world champion driver.

Supplement vitamin D to reduce risk of respiratory infections

A meta-analysis found that supplementing with recommended doses of vitamin D resulted in a 12% lower risk of developing upper respiratory tract infections.

Limit vitamin D intake to reduce pancreatic cancer risk

A meta-analysis of 10 randomized controlled trials found an increased rate of pancreatic cancer in people whose blood vitamin D levels were above 100 nanomoles per liter.

Skip routine vitamin D screening for asymptomatic adults

The U.S. Preventative Services Task Force found insufficient evidence to recommend screening for vitamin D deficiency in asymptomatic adults, as standard supplementation is likely sufficient.

Choose 1,000 to 2,000 IU of vitamin D3 for optimal health

The speaker personally takes 1,000 to 2,000 IU of vitamin D3 from a product called Microvitamin, which they designed specifically to avoid mega-dosing.
