Computed with the same four public criteria as every profile. The human-evidence grade on an indexed profile is set automatically and may change when it is hand-reviewed. It is not a safety score, not a purity rating, and not medical advice, and not a claim that this compound treats, cures, or prevents any condition.

What it is

Insulin aspart is a modified form of human insulin in which one amino acid is swapped so the molecules clump together less after injection, letting it be absorbed faster than regular human insulin. Like natural insulin, it helps move glucose from the blood into cells and signals the liver to release less glucose. It is sold under names including NovoLog and Fiasp, and in premixed forms combined with a longer-acting protamine version.
