“Daily Mail reports widespread Vitamin D deficiency amongst British children...and slather them with sunscreen”
Those children are deficient in D but it’s not due to sunscreen. My grandson was born there and lives there and was D deficient due to not enough sun shines there and their milk has no D added like ours does.
Grandson is a tennis player, had lessons all his life and now he is in his teens and has a professional standing in tennis and is on the court every day and still has to take an oil of some kind with D in it - he takes this under doctor care.
