Mineral sunscreens on the other hand are made from zinc oxide and titanium dioxide are physical particles that sit on the surface of the skin and scatter or redirect sun’s rays away from the skin. This is why they are less easily blended. Yet much better for your skin and overall health.
When looking for a mineral based sunscreen look for NON NANO zinc oxide or NON NANO titanium dioxide. If you choose options that are not non nano, this means they are made of coated nanoparticles which only sit on the surface of your skin and reflect UV light. They are more at risk of shedding if they are nanoparticles and therefor you’re more at risk of burning. In the world of skincare and marketing, these ingredients are sometimes called “organic” but they aren’t. Scientifically speaking, they are inorganic chemicals. So make sure you’re not buying into misleading marketing.
Europe has much stricter standards for sunscreens than America. Many US sunscreens aren’t able to be sold in Europe because they offer too little UVA protection. These UVA rays don’t cause sunburn but can cause aging and contribute to melanoma. On average, US sunscreens allow three times more UVA rays to pass through the skin than EU formulas.
I’ve recently started tracking my precise vitamin D exposure/absorption via the App D Minder.
What you need to keep in mind is just because the sun is shining, does NOT mean you’re absorbing or getting vitamin D. Your location, altitude, the angle of the sun in the sky, etc all effect how much actual vitamin D you’re getting. And if you’re wearing sunscreen, you’re practically blocking the benefit of vitamin D. Of course, always practice safe sun exposure without sunscreen but I always allow myself and my son time in the sun prior to applying sunscreen for this reason.

“In 2014, the American Academy of Pediatrics stated that infants under 12 months require 400 International Units (IU) per day and older children and adolescents require 600 IU per day.
The Vitamin D Council says that “children require 1,000 IU / 25 lbs body weight when they are unable to receive adequate sun exposure in order to reach optimal levels.”
The ideal amount of vitamin D depends upon various factors; those with chronic and autoimmune conditions could require higher levels.
While the typical lab test for vitamin D says that 30 ng/dL is a “normal” level, “normal” is not the same as “optimal”. See our full blog post in our bio for more information on testing.
Remember that U.S. RDA (Recommended Daily Allowance) levels are devised to prevent diseases of deficiency, which is not the same thing as promoting optimal health.
In fact, Sherry Rogers, MD stated in the September 2016 edition of her “Total Wellness” newsletter that vitamin D levels of 80-100 ng/dL are needed for optimal health.”
