What NIH publishes about these ten ingredients

Safety is a question about dose, and no dose is declared for anything. What follows is what NIH publishes about the named ingredients.

The problem with the question

Safety in a supplement is almost always a question about dose. Ashwagandha at a culinary pinch and ashwagandha at a gram are different propositions, and the thing that tells them apart is the Supplement Facts panel. This product did not supply one, so every statement on this page is about an ingredient rather than about this gummy, and is labelled as such.

Ingredient by ingredient

01the seller saysL-Arginine HClSupports healthy blood flow and circulation.†no amount is declared for this ingredient, or for any other
NIH publishes
NIH's Office of Dietary Supplements is blunt about this one: arginine supplements seem to have little to no effect on strengthening and muscle-building exercises, and there's little scientific evidence to support taking arginine supplements to increase strength, improve performance. The listing graphic for this product says L-Arginine HCl supports healthy blood flow and circulation.

02the seller saysAshwagandha RootHelps support stress balance and vitality.†no amount is declared for this ingredient, or for any other
NIH publishes
NCCIH: ashwagandha may be safe when taken in the short term (up to 3 months), and although it is rare, there have been a number of cases that link liver injury to ashwagandha supplements. It also notes that a small amount of limited evidence suggests two to four months may raise testosterone, and that people with hormone-sensitive prostate cancer should avoid it for that reason. The six-bottle pack on this product is sold as a 180-day supply.

03the seller saysHorny Goat WeedTraditionally used to support performance and drive.†no amount is declared for this ingredient, or for any other
NIH publishes
Horny goat weed (Epimedium) is on the artwork. None of the NIH pages this site opened publishes a human dose for it, so none is printed here. The listing graphic says it is traditionally used to support performance and drive - which is a sentence about tradition, not about a trial.
04the seller saysTribulus TerrestrisHelps support healthy testosterone levels and male vitality.†no amount is declared for this ingredient, or for any other
NIH publishes
The same NIH fact sheet: sellers claim tribulus raises testosterone, the few studies investigating it did not find that it had any benefit, and there's no scientific support for taking Tribulus terrestris supplements to improve exercise or athletic performance. It adds that some sports-medicine experts advise against taking any dietary supplements claimed to boost testosterone. The listing graphic for this product says tribulus helps support healthy testosterone levels and male vitality.

05the seller saysMaca Root ExtractSupports energy, endurance and stamina.†no amount is declared for this ingredient, or for any other
NIH publishes
Maca root extract is on the artwork and in the written pack. None of the NIH pages this site opened publishes a human dose for it, so none is printed here.
06the seller saysPanax GinsengHelps support mental focus, energy and overall performance.†no amount is declared for this ingredient, or for any other
NIH publishes
NCCIH: some research shows that taking oral Asian ginseng seems to improve sexual function in people with erectile dysfunction, and short-term oral use (by mouth, up to 6 months) of Asian ginseng in recommended amounts appears to be safe for most people. It also records that ginseng may lower blood sugar and may interfere with blood clotting. This is the one ingredient on the artwork with a positive NIH line behind it - and no amount of it is declared.

07named in prose onlyL-Citrullineno graphic in this pack names itno Daily Value is established for it
NIH publishes
L-Citrulline is named in the written pack and on no artwork. The NIH sources this site opened do not publish a dose for it, so this site prints none. The research this desk could not open without clearing a verification page is not cited here at all.
08named in prose onlyFenugreek extractno graphic in this pack names itno Daily Value is established for it
NIH publishes
NCCIH: fenugreek is believed to be safe for adults and children in the amounts commonly found in foods, and large doses may cause a harmful drop in blood sugar. Fenugreek is one of the four ingredients named only in the written pack, so this site cannot even tell you it is in the gummy.

09named in prose onlyZincno graphic in this pack names itthis one carries a Daily Value, so a panel would have to declare it separately by weight
NIH publishes
NIH's figures: the adult male RDA is 11 mg a day and the tolerable upper intake level for adults is 40 mg a day from all sources. Signs of too much zinc include nausea, dizziness, headaches, upset stomach, vomiting, and loss of appetite, and long-term excess can cause low copper. Zinc is also the ingredient most likely to be in a men's product at a meaningful amount - and it is named only in the written pack, with no figure anywhere.

10named in prose onlyVitamin D3no graphic in this pack names itthis one carries a Daily Value, so a panel would have to declare it separately by weight
NIH publishes
NIH's figures for men 19 to 70: the RDA is 15 mcg (600 IU) and the tolerable upper intake level for adults is 100 mcg (4,000 IU) a day from all sources. Yes, getting too much vitamin D can be harmful, and high levels of vitamin D are almost always caused by consuming excessive amounts of vitamin D from dietary supplements. If you already take a vitamin D supplement, this is the number to add up - and this product does not give you one to add.

The first six cards are the ingredients the product's own artwork names. The last four are named only in the written pack. Not one of the ten carries an amount, so every figure on the research side of a card is a dose somebody else studied — never a statement about this gummy.

The category warning

FDA publishes a running series of public notifications about products marketed for sexual enhancement that are found, on FDA laboratory analysis, to contain prescription drug ingredients that are not on the label. The warning FDA attaches to them is specific: such undeclared ingredients may interact with nitrates found in some prescription drugs, such as nitroglycerin and may lower blood pressure to dangerous levels.

Interactions worth raising with a pharmacist

Nitrates and blood-pressure medicines. See the category warning above.
Diabetes medicines. NCCIH records that Asian ginseng may lower blood sugar and that large doses of fenugreek may cause a harmful drop in blood sugar.
Blood thinners, and surgery. NCCIH records that ginseng may interfere with blood clotting, and that ashwagandha is not recommended before surgery.
Thyroid medicine, sedatives, immunosuppressants. All three appear on NCCIH's interaction list for ashwagandha.
Quinolone and tetracycline antibiotics. NIH records that these and zinc interfere with each other's absorption in both directions.

This site holds no stock and takes no payment. The prices above were supplied with the product pack and the checkout governs. No delivery date is printed anywhere on this site, because none was supplied.

And the cautions the bottle does not carry

No caution, warning, interaction line or storage line appears on any artwork supplied to this site.

Every caution on this site therefore comes from a named source rather than from the product. That is the wrong way round, and it is worth saying plainly.
