Yes, there are issues with “too much,” but the impact varies and sometimes can be self-identified.

One study showed women with blood levels over 32 ng/ml had a 6.2% reduction in sleep quality (you would know if this happened). Another shows that triglycerides increased 13 mg/dL and total cholesterol went up by 3.6 mg/dL when normalizing overweight people with 23.5 ng/mL to 30.6 ng/mL.

Other issues start to increase beyond 40 - 50 ng/mL.

Can there be benefit to even higher amounts? Possibly, but potential negatives keep piling in, too.

My last Vitamin D was 34 ng/mL, and I aim for 30 - 40 ng/mL.

My last Vitamin D was 34 ng/mL, and I aim for 30 - 40 ng/mL.

If I may ask, what daily dosage maintains you at that level?

Also, I had a doctor prescribe D2, while most supplements are D3. Any thoughts?

Thanks!

Do you happen to have links to either study (or both)?
