Customer Reviews of Life Extension Vitamin D3, 5000 IU, 60-Count
Customer Review: This is a very good product
Summary: 5 Stars
The warning on the label cautions the patient that high-dosage Vitamin D3 might cause all sorts of health problems. It advises monthly blood tests to check for serum 25(OH)D in the danger level. I am happy to report that for way more than 99% of the population, 5,000 IU will bring you into the optimal range. This warning is the manufacturer's way of limiting legal liability in case something goes wrong, but it basically is safe. 5,000 IU typically brings a blood level of 15 ng/mL up to around 40 ng/mL. You could go three times that high and it would still be safe according to research done by Dr. Reinhold Vieth at the University of Toronto. If everyone took 5,000 IU of D3 the world would be far healthier. Disclosure: I am not connected to this company except as a customer, I do not sell vitamins, and I am not a health professional.
Description of Life Extension Vitamin D3, 5000 IU, 60-Count
Vitamin D is synthesized in the body from sunlight. But, due to the winter season, weather conditions, and sunscreen blockers, the body's ability to produce optimal vitamin D levels may be inhibited. In fact, it has been proposed that annual fluctuations in vitamin D levels explain the seasonality of influenza. All of these factors point to the value of taking a daily vitamin D supplement to ensure optimal vitamin D intakeVitamins
