Get your vitamin D tested and if you’re low take supplements, or your doctor might prescribe you D. I feel strongly that we should be careful when we are young to get moderate sunshine, so we can continue to expose our skin to the sun as we age. Most of us baked ourselves in the sun as children, and so we have wrinkles and/or cancer scares that cause us to completely protect our skin now, and so what has resulted is that many adult Americans are extremely D deficient. I’m not a doctor, that’s just my opinion.
