When choosing a supplement, it’s important to look for a product that is:
- High-quality. Choose a supplement that is made by a reputable company and that has been tested for purity and potency.
- Appropriate for your needs. Make sure the supplement contains the nutrients you need and that the dosage is appropriate for you.
