The Claim
The concentration of aspartame required to induce cytotoxicity and genotoxicity in human blood cells in vitro (IC50 = 287 mg/L) is substantially higher than the maximum human exposure from dietary intake (≤0.5 mg/L at ADI).
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
The amount of aspartame needed to damage human blood cells in laboratory tests is more than 500 times higher than the maximum amount people are exposed to through their diet.
See the scientific wording
The concentration of aspartame required to induce cytotoxicity and genotoxicity in human blood cells in vitro (IC50 = 287 mg/L) is substantially higher than the maximum human exposure from dietary intake (≤0.5 mg/L at ADI).
When aspartame breaks down in the body, it produces methanol, which turns into formic acid. Formic acid blocks a key enzyme in the energy factory of cells, causing cells to run out of energy and accumulate damaging molecules. This stress kills cells and damages their DNA, but only at concentrations far higher than what people ever consume from food or drinks.
What the research says
1 studyThe study found that aspartame only starts damaging blood cells in a lab when the concentration is over 500 times higher than the most a person could ever get from eating or drinking it. So, normal diet doesn’t come close to the harmful level.
