Three people are reported to have been hospitalized in the past month for vitamin D toxicity with hypercalcemia (high blood levels of calcium and urea) after taking the product. It had approximately 188,640 IU of the vitamin in each serving size of six capsules instead of the intended level of 400 IU.
Symptoms of vitamin D toxicity include weakness, tiredness, headache, flu-like symptoms, nausea and diarrhea.
Recent research suggests that vitamin D can protect against a number of autoimmune diseases as well as supporting bone health. However the US Food and Nutrition Board recommends an upper safe level of 50 micrograms for total daily intake of the nutrient. One microgram of vitamin D3 is equivalent to 401 IU of vitamin D.
The Food and Drug Administration is asking consumers who have purchased the product, distributed nationwide, to return it to the manufacturer or distributor Solutions International.
