On 12/29 i started to take 3000iu vitamin d. 3 months later retested. it's still 31.0ng/ml. is there anything i should be concerned about or question?

Need higher dose!: That's a common level for someone taking 3000 iu/day. While within the normal range, many authorities say the optimal level is 50-80. It usually takes 5000-8000 iu/day to reach this level. It's perfectly safe to take that amount. I advise you take 6000 iu/day and recheck levels in 3 months. See https://www.vitamindcouncil.org/how-much-vitamin-d-is-needed-to-achieve-optimal-levels/ and my comment.
