However, customers need to be particularly cautious and Consult a doctor before taking this supplement as overdosing can lead to hypervitaminosis D, which is potentially fatal. The product is of high quality, and customers appreciate the neat packaging, but it is sourced from China. One issue raised by customers is that the instructions on the package suggest users take a teaspoon of the powder as a dose, which could lead to an overdose. There is a typing error on the package where customers have noticed that it says 14g of carbs per 46mg, but that has since been corrected to 14 mg. The purity of the vitamin D3 powder is also a common concern among customers, which the manufacturer has not provided a clear answer.
