"Ain't No Sunshine..."
It's that time of year. From October to March the sun will no longer be strong enough to generate the amount of Vitamin D most of us need. During the rest of the year, the sun's rays hitting our skin for about 15 minutes each day is enough. Our skin can use that energy to manufacture Vitamin D but once October comes that's no longer the case. Vitamin D is essental for healthy bones but we also suspect that it may play a key role in keeping our immune system working effectively and perhaps even preventing Seasonal Affective Disorder. Therefore, to keep healthy over the fall and winter months most of us should be supplementing our Vitamin D by 400 - 1000 IU per day. This is one situation where a supplement is almost always needed as it is very difficult to guarantee that Vitamin D intake by our diet alone. Speak to your doctor and/or your pharmacist to make sure this is is safe for you but for almost all of us this is a wise winter precaution.
