The truth about nutrient deficiencies
Nutrient deficiencies are uncommon with a broad and varied diet. But aging, hormonal factors, or diet can leave women short of four key vitamins and minerals: vitamin D, iron, vitamin B12, and calcium. Various tests can reveal nutrient deficiencies, including blood panels. Vitamin D and fish oil supplements may help prevent autoimmune diseases. Multivitamins are usually unnecessary, except in cases where age, pregnancy, digestive challenges, or certain medications interfere with the ability to get adequate nutrition.
Take melatonin supplements for sleep? Check your dosage
The number of people taking large amounts of melatonin (more than 5 milligrams per day) is at an all-time high. However, the amount in a supplement can be significantly higher than what the label shows. This can cause people to take too much, especially since many use melatonin regularly.
Supplementing your sleep
Sleep supplements, such as cannabidiol (CBD), melatonin, valerian, and chamomile promise a better night’s sleep. But there is little evidence showing that they are effective. In addition, supplements aren’t regulated, so it’s not always clear if a formula contains what’s listed on the label. Experts say that behavioral strategies are a better way to improve sleep. These include getting more exercise, going to bed and waking up at the same time each day, and sleeping in a cool, dark room.
Don’t waste time (or money) on dietary supplements
In 2022, Americans are projected to spend $35.6 billion on dietary supplements, even though there is little, if any, evidence of benefits. Loopholes in guidelines and clever marketing allow companies to promote these products with misleading promises. While some people may need specific supplements to help with deficiencies, for the average healthy person, following a diet with plenty of fruits and vegetables provides all essential vitamins and minerals.
Magnesium and blood pressure: What’s the evidence?
The FDA will allow companies to make certain health claims regarding the consumption of magnesium and a reduced risk of high blood pressure. But the evidence for the link is inconclusive and inconsistent.

In December 2021, the FDA warned consumers about an increase in supplements tainted with harmful ingredients, particularly supplements promising male enhancement or weight loss.
Harvard study: Fish oil doesn’t prevent depression
