Roll Call does not check drug interactions or assess personal safety.
Deoxyribonucleic acid material, typically derived from fish, yeast, or other biological sources, included as a source of nucleic acids or nucleotides.
Why it’s used
Taken by some under the idea that dietary nucleic acids support cellular repair or genetic health, though this rationale is not grounded in established nutritional science.
What the evidence says
There is no substantial mainstream clinical evidence that ingesting DNA as a supplement has a defined physiological effect; dietary nucleic acids are broken down during digestion like other nutrients rather than being incorporated intact.
