Sources of Vitamin C
Generally, nutrients have more bioavailability in naturally occurring food sources. However, ascorbic acid’s bioavailability is equal in both food and supplemental sources. Therefore, while it is better to consume natural foods such as red peppers, oranges, strawberries and grapefruit, because they offer other nutrients that are likely to have a higher bioavailability, it is acceptable to consume vitamin C from a supplement and still maintain adequate intake levels.

Famous quotes containing the words sources of and/or sources:
“Even healthy families need outside sources of moral guidance to keep those tensions from imploding—and this means, among other things, a public philosophy of gender equality and concern for child welfare. When instead the larger culture aggrandizes wife beaters, degrades women or nods approvingly at child slappers, the family gets a little more dangerous for everyone, and so, inevitably, does the larger world.”
—Barbara Ehrenreich (20th century)
“The sources of poetry are in the spirit seeking completeness.”
—Muriel Rukeyser (1913–1980)
