15 mins of daily exposure is good enough but that is not enough for the body. The amount that is synthesized by the body is accumulated along with the supplement extracted from food. So my advisor to you would be that buy a D-RISE Spray or powder sachet and consume once a week with water to complete your
vitamin D deficiency.
Next Steps
take
calcium and vit D combination tablets
Health Tips

calcium as well. this may cause problems in future. so take calcium supplement as well
