Menopause literally means the "end of monthly cycles" (the end of monthly periods) and comes from the Greek word pausis. It is an event that usually occurs in women in midlife, during their late fourties, and signals the end of the fertile phase of a woman's life. The date of menopause in women is formally defined as the time of the last menstrual period, in those women who have not had a hysterectomy. Those females who have their uterus removed but retain their ovaries do not immediately go into menopause, even though their periods cease.
Modern multivitamin products roughly classify into RDA (recommended dietary allowance) centric multivitamins with or without iron. Multivitamins can be a valuable aid for those with dietary imbalances or different nutritional needs, when supplementing the diet with additional vitamins and minerals. Individuals with dietary imbalances may include those on restrictive diets and those who cannot or will not eat a nutritious diet. Elderly adults and pregnant women have different nutritional needs than other adults, so a multivitamin may be recommended by a physician.
Severe deficiencies of vitamins and minerals may require medical attention and can be very difficult to treat with common over-the-counter multivitamins. In such situations, special vitamin or mineral forms with much higher potencies are available, either as individual components or as specialized formulations.Multivitamins in large quantities may pose a risk of an acute overdose due to the toxicity of some components, such as iron. In contrast to iron tablets, which can be lethal to kids, toxicity from multivitamin overdoses are very rare. Provided that proper precautions are taken, there appears to be minimal risk to supplement users of experiencing acute side effects due to excessive intakes of micronutrients, however research is still ongoing in regard to what health effects multivitamins have.
