Alpha Erec ingredients: all six, and what each one is

NIH's exercise and performance fact sheet is direct about the claim sellers make: they say larger amounts improve performance partly because the body converts arginine into nitric oxide, which expands blood vessels and increases blood flow. What the research found is that although it is limited, arginine supplements seem to have little to no effect on strengthening and muscle-building exercises or aerobic activities. On safety it says arginine seems safe up to 9 grams a day for several days or weeks, and that more can cause digestive discomfort and slightly lower blood pressure.

The most interesting ingredient here and the one with the most safety attached. NIH says research shows some ashwagandha preparations may be effective for insomnia and stress, that evidence is unclear on anxiety, and that there is limited evidence it may increase testosterone levels and sperm quality over two to four months. It also says ashwagandha may be safe in the short term, up to three months, and that there have been a number of cases linking liver injury to ashwagandha supplements.

None of the six sources we opened covers horny goat weed, so this site says nothing about what the evidence shows. It is a standard ingredient in this category, which is a statement about where it is sold rather than about what has been demonstrated.

NIH addresses this one head on. It notes that some sellers claim tribulus can improve performance by increasing levels of several hormones including testosterone, and then reports that the few studies investigating it did not find that it had any benefit. On safety it says tribulus has not been studied enough to know whether it is safe, and that studies in animals show high doses can cause heart, liver and kidney damage.

None of the six sources we opened covers maca. As with horny goat weed, this site reports only what the label prints and leaves the evidence question open rather than reaching for material it has not read.

The one ingredient here with a positive finding in the sources we read, and it is worth quoting precisely. NIH says some research shows that taking oral Asian ginseng seems to improve sexual function in people with erectile dysfunction. It also says short-term oral use up to six months in recommended amounts appears safe for most people, that insomnia is the most common side effect, that it might lower blood sugar, and that it might interact with certain medications. Recommended amounts is the phrase this label cannot be held against, because it publishes no amount.
