A4M CERTIFICATION EXAM — ANTI-AGING &
FUNCTIONAL MEDICINE 2026/2027 COMPLETE (100)
CURRENT TESTING QUESTIONS AND CORRECT
ANSWERS WITH DETAILED RATIONALES.
A4M
Prepare for the A4M Certification Exam – Anti-Aging & Functional Medicine with a
focused study resource designed to reinforce key concepts in areas outlined in the
ABAARM Written Exam blueprint, including mechanisms of aging, endocrinology,
cardiovascular disease, cancer prevention, cognitive health, nutrition, and functional
medicine. Use the material to strengthen clinical reasoning, reinforce important
concepts, and identify areas that may require additional review before the
certification examination. This resource is best suited for healthcare professionals
and A4M certification candidates preparing for advanced training and certification in
anti-aging and functional medicine.
MULTIPLE CHOICE.
SECTION 1: MECHANISMS OF AGING & MITOCHONDRIAL FUNCTION
(Questions 1-10)
1. Identify the true statement(s) concerning the role of mitochondria in
longevity, aging, and disease:
a. Decreased mitochondrial function results in increased oxidative damage,
caused by free radical formation combined with a decrease in antioxidant
enzyme system activity.
b. Maternal transmission of mitochondrial genomes is a factor in differences
in longevity between male and female organisms (Drosophila model).
c. Alteration of the electron transport chain (ETC) promotes survival and
enhances longevity (C. elegans model).
d. a, b, and c are true statements.
e. Only a and b are true statements.
Answer: d) a, b, and c are true statements.
Rationale: All three statements are correct. Mitochondrial dysfunction leads
to increased oxidative damage, maternal mitochondrial inheritance
, Page 2 of 34
contributes to sex-based longevity differences, and ETC alterations have been
shown to enhance longevity in model organisms.
2. Which of the following is a measure of the body's oxidative stress state,
with elevated levels demonstrated in schizophrenia and mild cognitive
impairment (MCI)?
a) Apo E4 protein
b) CRP (C-Reactive Protein)
c) Vitamin D3
d) Homocysteine
e) 8-OHdG (8-hydroxy-2'-deoxyguanosine)
Answer: e) 8-OHdG
Rationale: 8-OHdG is a marker of oxidative DNA damage and oxidative stress.
Elevated levels have been associated with neurodegenerative conditions
including schizophrenia and MCI.
3. Which of the following statements about telomeres is correct?
a) Telomeres lengthen with age
b) Telomere shortening is accelerated by oxidative stress and inflammation
c) Telomere length is not affected by lifestyle factors
d) Telomeres are only found in cancer cells
Answer: b) Telomere shortening is accelerated by oxidative stress and
inflammation
Rationale: Telomeres shorten with each cell division and are accelerated by
oxidative stress, inflammation, and other factors. Lifestyle interventions that
reduce oxidative stress may slow telomere attrition.
4. The "free radical theory of aging" was first proposed by:
a) Denham Harman
b) Leonard Hayflick
c) Elizabeth Blackburn
d) Peter Medawar
, Page 3 of 34
Answer: a) Denham Harman
Rationale: Denham Harman proposed the free radical theory of aging in the
1950s, suggesting that cumulative oxidative damage from free radicals
contributes to the aging process.
5. What is the Hayflick limit?
a) The maximum number of times a cell can divide
b) The maximum lifespan of a human
c) The maximum daily caloric intake for longevity
d) The maximum telomere length
Answer: a) The maximum number of times a cell can divide
Rationale: The Hayflick limit describes the finite number of times a normal
human cell population will divide before cell division stops, which is related to
telomere attrition.
6. Which supplement has been shown to decrease the rate of telomere
shortening?
a) Vitamin C
b) Vitamin D3
c) Vitamin E
d) Coenzyme Q10
e) EPA/DHA (Omega-3 fatty acids)
Answer: e) EPA/DHA (Omega-3 fatty acids)
Rationale: Omega-3 fatty acids (EPA/DHA) have been shown to decrease the
rate of telomere shortening.
7. Which compound, combined with calcium, has been shown to reduce
mortality in the elderly?
a) Vitamin C
b) Vitamin D3
c) Vitamin E
d) Coenzyme Q10
, Page 4 of 34
e) EPA/DHA
Answer: b) Vitamin D3
Rationale: Vitamin D3 combined with calcium has been shown to reduce
mortality in elderly populations.
8. Which supplement has been shown to reduce all-cause mortality, as
well as mortality specifically due to cardiovascular disease and cancers,
in men?
a) Vitamin C
b) Vitamin D3
c) Vitamin E
d) Coenzyme Q10
e) EPA/DHA
Answer: a) Vitamin C
Rationale: Vitamin C supplementation has been associated with reduced all-
cause mortality, cardiovascular mortality, and cancer mortality in men.
9. The alteration of the electron transport chain (ETC) promotes survival
and enhances longevity in which model organism?
a) Drosophila (fruit fly)
b) C. elegans (roundworm)
c) Mus musculus (mouse)
d) Homo sapiens (human)
Answer: b) C. elegans (roundworm)
Rationale: Studies in C. elegans have demonstrated that alteration of the
electron transport chain can promote survival and enhance longevity.
10. Mitochondrial dysfunction in aging leads to:
a) Decreased oxidative damage
b) Increased ATP production
c) Increased oxidative damage and decreased ATP production
d) Decreased apoptosis
