This site states this specific phrase directly under its "Stay Consistent" routine tip: cognitive nutrition is cumulative, so daily consistency is what delivers results.
Rather than framing the formula as producing an immediate, one-off effect, this site frames it as building over repeated daily servings — worth reading "cumulative" as the operative word tying this phrase to the site's broader gradual-timeline framing.
This site separately notes that because it works nutritionally, value tends to build the longer and more consistently you take it, which is why most people choose the multi-bottle kits — worth reading both statements together.
