Vitamin D3 as below:
Take vitamin d3 (not d2, the prescription form).
With levels that low i advise 20, 000 iu/day for 1 month, then 10, 000 iu/day and recheck your levels in 3 months. While 20, 000 iu is a high dose, vit d toxicity is very rare unless one takes over 40, 000 iu/day for months, so 20, 000 iu/day for a month should be quite safe.

also take 1 mg of vit k2.
