Is having low vitamin d bad? i was told mine was low at 12.5

Yes 12 is: Deficient. Associated with obesity. Chronic pain. Anxiety depression and insomnia. Would have your doc prescribe vit d 50k per week for a few months or simply take VitD3 over the counter 1000-3000 IU daily

Low Vitamin D level: It needs to be corrected as there is risk of following Osteoporosis and secondary Hyperparathyroidism Obesity as vit D has been linked to inability to loose weight It has been postulated that Vit D deficiency affects the immune system and people are more prone to get cancers and cardiovascular Disease You need a loading dose followed by maitanance dose

Sunlight: sunlight can increase your vitamin D2 level. Vitamin D2 gets converted into the active form D3 in the kidneys. You can also take supplemental vitamin D3- 400 units twice a day
