Icariin, Citrulline And Nitric Oxide: What The Research Shows
Icariin, the active compound in Horny Goat Weed, and Citrulline, an amino acid, are both studied for their potential role in supporting the body's nitric oxide pathway.
Red Boost includes both as named ingredients, though the specific amounts are not disclosed.
What nitric oxide has to do with circulation
Nitric oxide is a signaling molecule that helps relax and widen blood vessels, a process called vasodilation, which is relevant to healthy blood flow and circulation.
What research generally shows
Research on Citrulline, indexed on PubMed, has generally examined outcomes related to blood flow and exercise performance, commonly using specific, disclosed daily amounts in study designs. Icariin research follows a similar pattern.
The gap in Red Boost's disclosure
Why the missing amount matters here specifically
Unlike some botanicals where a wide dose range still produces some effect, Citrulline's research use is tied closely to specific gram-level amounts. Without knowing Red Boost's amount, it's difficult to know whether the formula approaches amounts used in published research or falls well short.
Applying this to Red Boost
Icariin and Citrulline are two of Red Boost's seven named ingredients, and likely the two with the clearest direct relevance to the product's central circulation claim.
