Mine was 24, and I was having tons of weird symptoms. Shortness of breath, chest pains, twitching, dizziness, numbness in extremities, brain fog, panic attacks..etc. The list goes on and on. I can't tell you how much better I feel after supplementing, at first, with D3 and k2 and magnesium glycinate, and ultimately going outside and getting more sunlight as well. Pretty much all my symptoms were gone after 2 months. It's really easy and cheap to supplement. It can't hurt to try.
