Vitamin D Supplements

This category includes vitamin D3 and vitamin D2 in softgels, tablets, gummies, sprays and liquid drops. Products may contain vitamin D alone or combine it with nutrients such as calcium, magnesium or vitamin K, with strengths ranging from everyday amounts to high-dose formulas. Compare the form, dose, intended age group and serving frequency carefully. Both D2 and D3 can raise vitamin D levels, although D3 may raise them higher and for longer, and this fat-soluble vitamin is generally absorbed better with a meal containing some fat. Excessive supplemental intake can be harmful, so high-dose use and suspected deficiency should be guided by appropriate professional advice and testing.
