The following scientist advocated use of vitamin megadoses:

Question

BlackTom AI · Accepted Answer

Linus Pauling advocated the use of large (megadose) quantities of vitamin C for prevention and treatment of disease, particularly the common cold and later claims about cancer.

1) Relevant knowledge points and concepts
- "Vitamin megadoses" refers to consuming vitamins at quantities far above recommended dietary allowances (RDA), often grams per day rather than milligrams.
- Linus Pauling (double Nobel laureate in chemistry and peace activist) popularized high-dose vitamin C beginning in the late 1960s and 1970s, writing Vitamin C and the Common Cold and promoting gram-level daily doses.
- The other scientists listed are historically associated with vitamins or nutrition but not megadose advocacy: Casimir Funk coined the term "vitamine," Frederick Hopkins discovered accessory food factors (vitamins), James Lind demonstrated citrus prevented scurvy, and Ilia Mechnikoff proposed beneficial bacteria and ideas about longevity.

2) Step-by-step reasoning
- Read each option and recall their major contributions.
- Casimir Funk: early 20th century biochemist who isolated and named vitamins — associated with discovery, not megadoses.
- Frederick Hopkins: showed the need for accessory food factors and linked diet to growth — foundational nutrition science.
- James Lind: conducted the first controlled clinical trial showing citrus cured scurvy in sailors — recommended citrus but not megadoses.
- Ilia Mechnikoff: immunologist who proposed probiotics and ideas on longevity — not a proponent of large vitamin doses.
- Linus Pauling: published popular works advocating several grams per day of vitamin C and other high-dose vitamin strategies — clearly matches “advocated use of vitamin megadoses.”

3) Calculations
- Not applicable; the question is identification-based, no numeric computation required.

4) Why the correct answer is correct
- Historical record and publications (Pauling’s books and public advocacy) directly show he recommended multi-gram vitamin C doses to prevent colds and improve health, fitting the phrase “advocated use of vitamin megadoses.”

5) Why other options are incorrect (brief)
- a. Casimir Funk: discovered/defined vitamins, did not promote megadoses.
- b. Frederick Hopkins: discovered the nutritional necessity of vitamins, not megadose advocacy.
- d. James Lind: discovered citrus prevents scurvy (therapeutic amounts), not modern megadose promotion.
- e. Ilia Mechnikoff: proposed probiotics and research on longevity, not vitamin megadoses.

6) Conclusion
Therefore, the correct answer is c. Linus Pauling, which matches the provided answer.
