Read the first 7 Special Populations & Supplementation flashcards as text

  1. A client with hypertension wants a supplement to help lower blood pressure. Which has the strongest evidence?

    Answer: Magnesium

    Magnesium supplementation has consistent meta-analytic evidence for modest blood pressure reduction, particularly in individuals with low magnesium status.

  2. Which statement about iron supplementation in athletes is MOST accurate?

    Answer: Iron supplementation should only be given when deficiency is confirmed by lab testing

    Iron supplementation should be reserved for confirmed iron deficiency or iron-deficiency anemia, as excess iron supplementation in non-deficient athletes provides no benefit and carries risks.

  3. A client with ADHD who takes methylphenidate asks about taking zinc supplements. What is the MOST appropriate response?

    Answer: Some research suggests zinc may support ADHD symptom management but advise discussing with their prescriber

    Some research suggests zinc deficiency is common in ADHD and supplementation may be a useful adjunct, but any supplement use alongside prescription medication requires physician coordination.

  4. Which population has the HIGHEST requirement for folate supplementation?

    Answer: Women of childbearing age planning pregnancy

    Women planning pregnancy should take 400–800 mcg of folic acid daily to prevent neural tube defects, which occur in the first 28 days of embryonic development.

  5. A client with polycystic ovary syndrome (PCOS) is interested in supplements. Which has the MOST evidence for improving insulin sensitivity in PCOS?

    Answer: Inositol (myo-inositol)

    Myo-inositol has multiple randomized controlled trials showing improvements in insulin sensitivity, hormonal profiles, and ovulatory function in women with PCOS.

  6. What is the primary concern with high-dose beta-carotene supplementation in smokers?

    Answer: It significantly increases lung cancer risk in smokers

    The ATBC and CARET trials demonstrated that high-dose beta-carotene supplementation increased lung cancer incidence and mortality in current smokers.

  7. Which supplement has the best evidence for reducing exercise-induced muscle damage in master athletes (over 50)?

    Answer: Tart cherry juice or concentrate periworkout

    Tart cherry juice contains anthocyanins and other polyphenols with anti-inflammatory properties that have been shown in multiple trials to reduce DOMS and muscle damage markers.
