I’ve been trying to research this, but can’t find a trusted source. does anyone know the safe level of Vitamin D to take daily?
From what I have read on FR and elsewhere - it is all over the place. Most folks (and doctors) think the recommended dose is too low (don’t recall what it is - 1200 units a day?)
I try to remember to take 1000 in the morning and 1000 at night. I seem to recall others are in the 5000+ range per day? A doc can do a test, but I think it is fairly expensive. I also recall folks going to the doc, getting a 30,000+ dose and then followed by typical doses.
I’m sure I’m fuzzy on my actual numbers, but they are all over the place!
"The objective of this review was to apply the risk assessment methodology used by the Food and Nutrition Board (FNB) to derive a revised safe Tolerable Upper Intake Level (UL) for vitamin D. New data continue to emerge regarding the health benefits of vitamin D beyond its role in bone. The intakes associated with those benefits suggest a need for levels of supplementation, food fortification, or both that are higher than current levels. A prevailing concern exists, however, regarding the potential for toxicity related to excessive vitamin D intakes. The UL established by the FNB for vitamin D (50 µg, or 2000 IU) is not based on current evidence and is viewed by many as being too restrictive, thus curtailing research, commercial development, and optimization of nutritional policy. Human clinical trial data published subsequent to the establishment of the FNB vitamin D UL published in 1997 support a significantly higher UL. We present a risk assessment based on relevant, well-designed human clinical trials of vitamin D. Collectively, the absence of toxicity in trials conducted in healthy adults that used vitamin D dose 250 µg/d (10 000 IU vitamin D3) supports the confident selection of this value as the UL."
