Saw palmetto is a popular “natural” choice for urinary symptoms from an enlarged prostate, but high-quality studies show little or no real benefit. Men are urged to talk with a doctor first, both to rule out serious causes and avoid misplaced hope.

Elderberry syrup or tea may help reduce the duration and severity of cold and flu symptoms, but the evidence for these benefits is uncertain. Claims that elderberry products can prevent viral infections or boost immunity are unproven.

As we get older, noticeable bruises are usually related to thinning skin and increasing fragility of the tiny blood vessels in the outer layer of skin. There is not much people can do about this, but they should see their doctors if bruising is excessive or becomes painful.

Taking magnesium supplements has become popular in recent years, and some evidence suggests this practice may help lower blood pressure, especially for those with high blood pressure or low magnesium levels. But a healthy diet is a better way for people to ensure they’re getting enough of this essential nutrient.

A pescatarian diet pairs plant-based eating with fish and shellfish, offering key nutrients and heart- and brain-protective omega-3s. Choosing smaller, sustainably caught seafood helps limit environmental impact and mercury exposure.

Women over 60 need less iron than they did before menopause, when they lost iron through menstruation. Many conditions can lead to iron loss and iron-deficiency anemia, when the body can’t make enough red blood cells to properly carry oxygen throughout the body. Signs of iron deficiency include pale skin, fatigue, shortness of breath, weight loss, and chest pain. Tests can reveal iron deficiency and underlying reasons for iron loss. People should not take iron supplements without checking with their doctor. Too much iron can damage organs.
