Supplements commonly provide 99 mg per serving, and food provides more (no cited trial states the dose it used). No upper limit is established, so no maximum is stored. That is not a statement that larger amounts are safe.

At 1.5 g a day for 8 weeks, a double-blind trial in 84 adults with type 2 diabetes found no change in blood lipids (PMID 33532874). At 5 g a day for 4 weeks, two double-blind trials found an effect: in 63 mildly hypercholesterolaemic adults total cholesterol changed -1.6% versus 0.03% on placebo (PMID 24920270), and in 34 adults eating three eggs a day LDL-C rose 1.7% versus 14.3% on placebo (PMID 27177615). At 15 g a day for 14 days, total and LDL cholesterol fell in 80 healthy adults (PMID 37049486), but uric acid rose and iron and selenium status fell. The meta-analyses disagree on dose: one found reductions at doses above 4 g a day (PMID 29037431), another found the LDL-C reduction at doses up to 1,500 mg and not above (PMID 35331862). No trial compared doses, so the curve is flat above 5 g and no minimum, optimal or safe ceiling is set.
