Vitamins
The most obvious thing you can agree with in this article is that growing your own food has many benefits that include higher levels of nutrition versus store bought food. There is no doubt that some vitamins and minerals help. I can give you a specific example. A potassium deficiency has all kinds of negative effects on the body including one I experienced and that is muscle spasms. A doctor prescribed potassium pills and it went away immediately after having been a multi year problem. Now, it's been a decade and since I make sure to continue taking either potassium supplements or eating foods that contain it I haven't had the spasm problem again.
That is just one example. Consider the benefits of natural intake first over vitamin supplements but aging also brings on the need for targeted supplementation for those of us that might have deficiencies or health issues that can benefit from them.
Sunscreen Safety
Consider wearing long sleeved shirts even when playing tennis. Modern fabrics allow it without overheating in the sun and give you a SPF 15-30 protection depending on the color and type of fabric. Putting Zinc Oxide based cream on your nose and top of your hands will give you some very targeted protection as well.
