In their words
“shellfish like uh oysters can be great because of zinc we need zinc to be able to produce stomach acid”
a former research biochemist
Supermarket oysters are farmed, routinely tested, irradiated with UV light, and filtered, providing a safer and more affordable zinc source.
Oysters replenish zinc and trace minerals essential for reproduction.
Oysters are rich in copper and have a great balance of zinc and copper, which helps balance absorption of both nutrients.
a certified naturopathsponsoredOysters are highlighted as a great source of important minerals beneficial for immunity and hormone function.
With care
Some of the minds attach conditions. These are worth reading before you begin.
