Component

Trait anxiety

Independent cellular process record; interpretation is limited by each linked claim and its study context.

3 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.

What acts on it

  1. The Ghana trial found no significant lysine-placebo difference in trait-anxiety change or skin-conductance stress responses.

Where it participates (unsigned role)

  1. One week of combined lysine and arginine reduced trait and stress-induced state anxiety in a randomized trial of 108 healthy Japanese adults.
