Another great choice is this food derived Thorne Research Zinc Picolinate (amazon link), which is in the excellently absorbed zinc gluconate form, as opposed to the poorly
absorbed zinc oxide found in almost all grocery store products.
The same can not be said for bargain basement supermarket pills; poorly

Instead of being
absorbed by the skin,
zinc oxide and titanium dioxide sit on the skin and physically block the sun.

absorbs ultraviolet light.
Look for more safe sunscreens made with less toxic ingredients, specifically
zinc oxide and titanium dioxide — these two are not
absorbed into the skin so they are safer to apply.
Unlike chemical sunscreens that
absorb UV energy, our non-nano
zinc oxide formula repels UVA and UVB rays.
Titanium dioxide and
zinc oxide sit on the skin's surface to deflect damaging UVA / UVB rays, unlike chemical sunscreens that typically penetrate the skin and
