Component

Measured plasma insulin, growth hormone or IGF-1, study specified

Measured plasma insulin, growth hormone or IGF-1, study specified. Species, exposure and limitations are retained in each linked claim.

1 recorded relationships. Experimental role, claim status and evidence remain attached to each record.

How nutrients influence it

Every nutrient with a recorded effect on this component, credited to the nutrient that acted rather than the chapter that recorded it. Open a nutrient to see the findings and the conditions they were measured under.

How nutrients reach it in more than one step

Chains of two or more recorded steps that end here, grouped by the nutrient they start from. Each step is a separate finding, so a chain is a route a mechanism could take, not proof that it does.
