The results are available online now in ConsumerLab's new Vitamin D Supplements Review, which includes test results and comparisons for 31 products, including products which contain vitamin D in combination with other ingredients. ConsumerLab also selected Top Picks among combination products containing calcium, magnesium, vitamin K, and/or boron. There were also big differences in price, with the cost to obtain an equivalent amount of vitamin D (1,000 IU) ranging from just 1 cent from a vitamin D-only tablet to over $9.99 for a liquid combination product.Īmong vitamin-D only products that were Approved, ConsumerLab chose Top Picks for low (400 IU) and moderate (1,000 IU) doses of vitamin D, which are both amounts that can generally be safely used to maintain adequate levels of vitamin D, as well as for high (2,000 IU) and very high (5,000 IU) doses of vitamin D, which are more appropriate for correcting deficiencies. Products with even higher amounts are on the market. In addition, the daily dose of vitamin D ranged 12-fold from just 400 IU (10 mcg – the Recommended Daily Allowance for infants) to 5,000 IU (125 mcg) (which exceeds the safe Tolerable Upper Intake Level). However, one combination product was found to contain more than twice its listed amount of vitamin D, and two other combination products were found to contain just a small percentage of the vitamin K2 listed on their labels. The tests showed that most of the products contained their claimed amounts of vitamin D. Products containing minerals or herbal ingredients were also tested for contamination with lead and other toxic heavy metals, and pills were tested to check for proper disintegration. Each supplement was tested to see if it contained its claimed amount and form of vitamin D and other key ingredients. To help consumers, ConsumerLab recently selected, purchased, tested, and compared popular vitamin D supplements sold on the market, including tablets, capsules, liquids and gummies providing vitamin D alone, or in combination with calcium, magnesium, vitamin K, and/or boron. With so many different vitamin D supplements on the market, how can consumers know which products provide the best dose of vitamin D to meet their needs at the best quality and cost? However, getting too much vitamin D can have adverse effects. It's no wonder that it has been the #1 supplement in popularity year-after-year in ConsumerLab's survey of supplement users. White Plains, New York, Getting sufficient vitamin D is essential for healthy bones and has a wide range of other health benefits.
