Dietary supplements are extremely popular, and multivitamins can seem particularly appealing for their potential to cover multiple possible nutritional issues. But do you really need supplements? Do multivitamins actually help? Should you take a multivitamin every day? Contrary to common marketing practices, we do not believe that multivitamins are a worthwhile expense, as they can be (at best) a waste of money or (at worst) cause dangerous nutrient toxicities.

In general, melatonin is quite safe, though experts recommend being conservative with the dosage and the number of nights in a row that you use it. Here's a breakdown of common questions about melatonin supplements.

It’s no scientific breakthrough that music can impact our brain mental state. Research shows that music can significantly improve mood, stress, cognitive performance, and even endurance and power when applied correctly. How exactly does music benefit the brain and body?

Digestive enzymes are critical for breaking food down into its nutritional components in our gastrointestinal (GI) tract. And if this process is disrupted, common GI symptoms like bloating, diarrhea, and stomach pain can ensue. It's for this reason that digestive enzyme supplements have been getting attention lately—there is speculation that they boost those processes and help relieve symptoms of indigestion. But the clinical evidence shows that digestive enzymes are not effective at ...
