The Trick To Significantly Increase Vitamin D In Mushrooms 

What Is Vitamin D

Vitamin D is a fat-soluble vitamin that our body makes naturally when exposed to the sun, which supports a healthy immune system and strong bones. We need about 15-20 mcg or 600-800 IU of Vitamin D a day. (1)

Due to our modern, mostly indoor western lifestyles, observational studies suggest about 40% of the American and European populations are deficient in this critical nutrient. (2, 3) A small study recently published in the Journal of Clinical Endocrinology & Metabolism, found that of 216 patients hospitalized for COVID in a Spanish hospital, 80% of them were Vitamin D deficient. (4)

For those who can’t make it outdoors consistently to get adequate amounts, Vitamin D is also found in a small number of foods, mostly animal-based. Fatty fish like wild salmon are a substantial source of Vitamin D. For example, one three-ounce serving of coho salmon provides 14.2 mcg or 570 IU of Vitamin D. For adults under 70, that’s 95% of your daily needs.

While beef and egg yolks do provide some vitamin D, it’s an insignificant amount. One large egg provides 1.1 mcg or 44 IU (6% of recommended daily intake) while a three-ounce serving of ground beef provides just 1.7 IU. (not even 1% of the daily recommended intake). Other sources like cod liver oil and beef liver are more substantial sources, however, are not always easy to get, or get down. (5)

Mushrooms, on the other hand, are incredibly easy to find, inexpensive, flavorful, and bursting with Vitamin D when prepared in the specific way I outline below.
