The Claim

Exposure to aspartame at concentrations up to 100 mg/L does not significantly alter total antioxidant capacity or total oxidative stress levels in cultured human blood cells.

Description
1 study reviewed
In plain English

When human blood cells in a lab are exposed to aspartame at concentrations up to 100 mg/L, there is no measurable change in their antioxidant capacity or oxidative stress levels.

See the scientific wording

Aspartame exposure at concentrations up to 100 mg/L does not significantly alter total antioxidant capacity or total oxidative stress levels in cultured human blood cells, suggesting no measurable oxidative imbalance under these in vitro conditions.

Why this might work

When aspartame breaks down in blood cells, it turns into methanol and other parts, which can interfere with energy production in mitochondria. But at concentrations up to 100 mg/L, this breakdown does not slow down energy production enough to cause a buildup of harmful reactive molecules or reduce the cell's ability to neutralize them, so antioxidant levels and oxidative stress stay unchanged.

  1. Study: The in vitro cytotoxic, genotoxic, and oxidative damage potentials of the oral artificial sweetener aspartame on cultured human blood cells

    When scientists tested aspartame on human blood cells in a lab, they found that even at high doses up to 100 mg/L, it didn’t change the cells’ antioxidant levels or oxidative stress — meaning no harmful imbalance was detected.
