Food-based supplements

Not all supplements are created equal. Many are made with isolated, lab-made nutrients, while food-based (or whole-food) supplements are made from concentrated foods, like dried greens, mushrooms or fruit powders. Supporters say these bring along the natural cofactors found in food. Research comparing the two is limited, and some isolated forms, like vitamin D3, work very well.

What I tell clients:

• Food comes first; supplements fill gaps, they don't replace meals
• Look for third-party testing, such as an NSF or USP seal
• Read the label for fillers, dyes and unnecessary extras
• More isn't better, especially with vitamins A, D, E and K

Bring your supplements to your next appointment and check with your doctor or practitioner, since some can interact with medications.
