I took vitamin d3 5,000 iu for the first time and now i feel weird and my hands and feet went cold and now i feel hot , could it be to strong for my body?

Likely unrelated: I see no reason that ingestion of the vitamin supplement over a brief period would trigger any noticeable symptoms at all. The 5000 iu is above the 4000iu suggested as the maximum daily dose for those not treating a deficiency. You can stop for a few weeks, re-start later & see if it causes the same pattern. I would consider other issues more likely.
