Component
Human plasma cyclic GMP concentration
Human plasma cyclic GMP concentration. Interpret through the linked experimental species, preparation, compartment and exposure; no universal causal effect is implied.
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.
Other things that act on it
Enzymes, hormones, genes, and other components with a recorded effect. These are not nutrients, so they do not count toward the arrows above. Each finding names the chapter that recorded it.
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 it does
Every recorded relationship this component is part of, grouped by its role. Plain wording comes first; the technical statement follows.
What acts on it
The 12-week purified berry anthocyanin trial reported higher plasma cGMP versus placebo.

**Purified berry anthocyanins changed human vascular function.** A 2011 study included a 12-person acute crossover and a 150-person, 12-week trial of 320 mg/day. Flow-mediated dilation (FMD) and plasma cGMP improved; LDL cholesterol and soluble VCAM-1 decreased, with HDL cholesterol increasing. Additional inhibitor experiments in six people and rat aortic rings supported involvement of NO–cGMP signaling. The accessible abstract does not identify every inhibitor or its route, so this reference does not invent those details. FMD is vascular physiology, not proof of a particular parent molecule binding eNOS or prevention of cardiovascular events. [Zhu et al., 2011](https://pubmed.ncbi.nlm.nih.gov/21926181/).
