If you are taking large doses of vitamin D (lets say more than a few thousand a day) get your serum levels checked from time to time. I had been taking 5-10k per day in 5k IU pills regularly and my levels were right at the top of the safe range.
Too much vitamin D can screw with your calcium and thus nervous system.
Can someone please explain to me the toxicity of vitamin D and how it interacts with K2? I feel like K2 isn’t mentioned often in discussions about vitamin D and I wonder why this is.
As I understood it -- if you're tested low, you can take 5 - 10k per day for about a month to restore your levels, then drop down to 2 - 5k daily. High doses over a long period is toxic, and low doses are ineffective.
Even if your bodies are pretty similar, you still don't know if your vitamin D levels will follow the pattern that his did. If you're messing with vitamin D supplements you should talk to a doctor and/or get your blood tested.
