Portobello mushroom burgersPortobello mushroom burger

Vitamin D is an essential vitamin needed for our bodies to function at their best. Vitamin D helps with the absorption of calcium which helps keep bones, teeth and muscles strong.

It’s known as the sunshine vitamin for good reason as we mainly get it from exposure to the sun. Not many foods are good sources of vitamin D, some milks and milk alternatives have vitamin D added in, but mushrooms are the only naturally occurring source! Just like humans, mushrooms can make vitamin D when exposed to sunlight.

This Portobello mushroom burger, with all its fillings, is not only a source of vitamin D but also a great source of calcium too!
