Type: Vitamins
Organic compounds essential for normal growth and nutrition. Required in small quantities in the diet because they cannot be synthesized by the body.
Absorption: Fat-soluble vitamins require dietary fat for absorption. Water-soluble vitamins are generally well-absorbed but excess amounts are excreted.
Interactions: Some vitamins can interfere with medications. Fat-soluble vitamins can accumulate in the body.
Watch out for
Possible interactions or cautions — talk to a healthcare provider if unsure.
