The Claim
Cholesterol constitutes approximately 50% of the lipid composition of mammalian cell membranes and is essential for maintaining membrane fluidity, integrity, and selective permeability.
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.
Cholesterol makes up about half of the fatty material in the outer layer of your body's cells, and it helps keep that layer flexible, strong, and able to control what comes in and out.

What the research says
2 studiesThis study found that too much cholesterol in sperm cells makes their outer layer too stiff, which stops them from working properly—showing that cholesterol is super important for keeping cell membranes flexible and functional.
Study: Excess membrane cholesterol alters human gallbladder muscle contractility and membrane fluidity.
When there's too much cholesterol in cell membranes, they become stiff and don't work well — but when scientists remove the extra cholesterol, the membranes become flexible again. This shows cholesterol helps keep cell membranes just the right consistency.
