What Would You Like to Understand Better?

Pick a topic, or search for a nutrient, a condition or a supplement name.

What would you like to understand?

Food first. Supplements second.

Most nutrients are best understood through food, habits and context. A supplement may be useful for some people in some situations, but it isn’t a shortcut and it doesn’t replace a good foundation.

Learn How to Evaluate Supplements

Foundations of Health

Build the Foundation First

Seven foundations of health. Appropriate supplementation is one of them, not the whole picture.

  1. 1Nutrition
  2. 2Movement
  3. 3Sleep
  4. 4Stress management
  5. 5Hydration
  6. 6Preventive care
  7. 7Appropriate supplementation

Supplements should support the foundation—not replace it.

  • Are you pregnant?

FAQ

Frequently Asked Questions

Straight answers, without the sales pitch.

Do I need supplements if I eat a healthy diet?

Not necessarily. A varied diet covers many people’s needs. Some life stages, diets and health situations may call for a supplement, which is a question worth raising with a healthcare professional.

Are natural supplements always safe?

No. “Natural” doesn’t mean risk-free. Supplements can cause adverse effects, be taken at excessive doses and interact with medications or health conditions.

How do I know if a supplement works?

Look at what the research actually shows for that ingredient, at the dose used, in people like you. Be cautious with miracle claims, proprietary blends and testimonials.

Can I take several supplements together?

Sometimes, but combinations can overlap, duplicate nutrients or interact. Review your full list with a pharmacist or healthcare professional.

Can supplements replace my medication?

No. Don’t stop or change prescribed medication on the basis of a website. Talk with your prescriber first.
