Ingredient Profile · Seed Extract
Grapefruit Seed Extract
Rich in naringenin, studied for glucose uptake efficiency.
Mechanism
Grapefruit seed extract is a source of naringenin, a flavonoid studied for helping cells absorb glucose more efficiently and for supporting healthy insulin sensitivity through a separate mechanism than the formula's other ingredients.
What the evidence shows
Naringenin's mechanism is documented in laboratory research; human clinical trial data on grapefruit seed extract specifically for blood sugar outcomes is more limited than for ingredients like ginseng or green tea.
Safety notes
Grapefruit-derived compounds are well known to interact with a range of prescription medications by affecting how the liver processes them. Consult a doctor or pharmacist before use if you take any prescription medication.
