The Claim
Exposure to aspartame at concentrations of 25 mg/L and higher significantly reduces viability of cultured human blood cells in a concentration-dependent manner, with an IC50 of 287.342 mg/L, indicating direct cytotoxic effects on primary human lymphocytes under in vitro conditions.
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.
Aspartame at concentrations of 25 mg/L and higher reduces the viability of human blood cells in laboratory cultures, with half the cells dying at 287.342 mg/L, demonstrating a direct toxic effect on lymphocytes.

When aspartame breaks down in blood cells, it turns into methanol, which becomes formic acid. Formic acid blocks a key enzyme in the cell's energy factory, stopping the production of energy. Without energy, the cells lose their ability to stay alive and die.
What the research says
1 studyIn a lab test, scientists found that when human blood cells were soaked in very high doses of aspartame, more of them died as the dose went up — exactly as the claim says. Half the cells died at 287 mg per liter, which matches the claim perfectly.
