Question 1

What does NSF Certified for Sport actually mean?

Accepted Answer

It means every batch of the supplement is tested by an independent third-party lab (NSF International) to ensure it's free from 270+ banned substances and contains exactly what's on the label. It's the only certification recognized by major sports organizations (NCAA, NFL, MLB, NBA, Olympics, WADA). If you're drug-tested, NSF Certified is the only way to guarantee your supplements are safe.

Question 2

Why can't I just use regular supplements if I'm drug-tested?

Accepted Answer

Because 12-25% of supplements contain banned substances not listed on the label—contamination during manufacturing, mislabeling, or intentional spiking. Even trace amounts can trigger a positive drug test. In strict liability sports (NCAA, Olympics, professional leagues), you're responsible for everything in your body—'I didn't know' is not a defense. NSF Certified eliminates that risk.

Question 3

I'm in high school and not drug-tested yet. Do I need NSF Certified supplements?

Accepted Answer

If you're planning to play NCAA sports, join the military, or go pro, yes. Start using NSF Certified now to build safe habits and avoid contamination. NCAA drug testing is strict—one positive test can cost your scholarship or eligibility. All high school athletes heading to college should use NSF Certified to protect their future.

Question 4

Are NSF Certified supplements more expensive?

Accepted Answer

Yes, typically 20-30% more than non-certified products. But the cost of a positive drug test is infinitely higher—lost scholarship (worth $50,000-$200,000), lost eligibility, lost career, or disqualification from competition. NSF Certified is insurance for your athletic career.

Question 5

Can I trust other certifications like GMP Certified or Informed Choice?

Accepted Answer

GMP (Good Manufacturing Practices) only certifies the facility, not the product. Informed Choice is similar to NSF but less widely recognized. NSF Certified for Sport is the gold standard recognized by NCAA, WADA, NFL, MLB, NBA, and Olympic organizations. If you're drug-tested, stick with NSF Certified—it's the safest and most recognized certification.

Question 6

What sports require NSF Certified supplements?

Accepted Answer

Any sport with drug testing: NCAA (all divisions), professional leagues (NFL, CFL, MLB, NBA, MLS, NHL), Olympic sports, international competitions (WADA-tested), military (certain positions), first responders (certain departments), powerliŌing and bodybuilding federations (tested divisions), combat sports (boxing, MMA, wrestling), track and field, swimming, cycling, and more. If you're tested, you need NSF Certified.

Question 7

What happens if I test positive while using NSF Certified supplements?

Accepted Answer

NSF provides documentation proving the supplement was tested and certified, which can support your defense. However, you must use the supplement exactly as directed and not stack with non-certified products. NSF Certified drastically reduces risk but doesn't eliminate human error (taking wrong dosage, mixing with contaminated products, etc.). Follow directions and use only NSF Certified products.

Question 8

Can I stack NSF Certified supplements with non-certified supplements?

Accepted Answer

Absolutely not. If you're drug-tested, every supplement you take must be NSF Certified. Mixing certified and non-certified products defeats the purpose—one contaminated product can cause a positive test. If you're serious about protecting your career, use only NSF Certified supplements across the board.
