Vigorus Side Effects: Ingredient by Ingredient

Does Vigorus cause side effects?

No study has tested Vigorus itself, so there is no measured list of side effects for this capsule. What we have is research on each of its eight ingredients, and that research points to a few clear questions about medicines.

Each capsule holds two nutrients with printed amounts: 20 mg of niacin and 11 mg of zinc. It also holds a 570 mg proprietary blend of six ingredients with no single amounts. Because the blend amounts are hidden, plan as if each one is there in a real amount.

The label prints one caution. Here it is word for word:

"Do not exceed recommended dose. Not for use for those under the age of 18 or pregnant or nursing mothers. Consult with a physician prior to use especially if you are taking a medication or have a medical condition."

The label also says, in capital letters: "KEEP OUT OF REACH OF CHILDREN. DO NOT USE IF SAFETY SEAL IS DAMAGED OR MISSING." The suggested use is one capsule daily. The label gives no time of day and no food rule. You can see the whole panel on the Supplement Facts page.

What is known about each Vigorus ingredient?

At the amounts in one capsule, most of the eight ingredients have mild or unknown effects. The table sets out what the research says for each one, in label order, and which medicines to raise with your doctor.

US rules list a blend from most to least by weight. So L-citrulline can be at most 570 mg, and saffron at most 95 mg. These are upper limits, not real amounts. The later ingredients are likely much smaller.

Two things stand out. Niacin and zinc are the only amounts you can check against safe limits, and both sit below them on their own. The blend ingredients are all far below the doses used in research, which also means less is known about them at this size.

Which medicines should you ask about before taking Vigorus?

Ask first if you take blood pressure medicine, a blood thinner, certain antibiotics or seizure medicine. Four ingredients have a known link to one of those groups.

Can you stack Vigorus with a multivitamin?

You can, but add up the niacin and zinc first. A multivitamin often carries both, and the totals are what count against the upper limits.

Vigorus gives you 20 mg of niacin. The upper limit from supplements is 35 mg a day. NIH ODS says flushing from nicotinic acid can start at 30 mg or more. So a multivitamin with 15 mg or more of niacin could put you at the point where flushing shows up.

Vigorus gives you 11 mg of zinc, which equals the daily need for adult men. The upper limit is 40 mg a day from all sources. A zinc lozenge habit or a second zinc product can push you past it. Over time, too much zinc can lower copper.

1. 1

   Read both labels

   Find the niacin and zinc lines on your multivitamin and on the Vigorus panel.

2. 2

   Add the numbers

   Niacin should stay at 35 mg or less a day. Zinc should stay at 40 mg or less, food included.

3. 3

   Adjust if needed

   If you go over, ask your doctor which product to drop or change.

Who should not take Vigorus?

Vigorus is for adult men 18 and older. The label rules out anyone under 18 and anyone pregnant or nursing, and the ingredients add a few more groups who should ask first.

• Anyone under 18. The label names this group directly.
• Anyone who is pregnant or nursing. The label names this group too.
• Men who take blood pressure medicine or a blood thinner, until a clinician has seen the label.
• Men on quinolone or tetracycline antibiotics, unless they space the doses as advised.
• Men on seizure medicine, until they have asked about the carnitine.
• Anyone with a medical condition, until a physician says it is fine. The label asks for this.

Only take one capsule a day. The label says not to exceed the recommended dose, and taking two does not make up for a missed day. Store the bottle below 30°C (86°F), in a cool, dry place.

Why does the FDA warn about products in this category?

The FDA warns that some products sold for sexual enhancement have contained hidden prescription drug ingredients. This is a warning about the category as a whole, not a finding about Vigorus.

The FDA page on hidden ingredients explains that such drugs can interact with medicines and cause harm. It is a good reason to buy sealed bottles from a known seller and to read the label before you start. We only report what the Vigorus label prints.

• Buy from a seller you can reach by phone. The Vigorus order desk is +1 (323) 391-7352.
• Check that the safety seal is in place before the first capsule.
• Make sure the Supplement Facts panel matches: niacin 20 mg, zinc 11 mg, blend 570 mg.
• See the where to buy page for how to tell a real bottle.

What should you do if you feel unwell?

Stop taking the capsules and call your doctor. In an emergency, call 911.

Mild stomach upset may settle on its own, but anything that lasts or worries you is a reason to stop. Keep the bottle so your doctor can read the label.

Then tell the order desk at +1 (323) 391-7352 and give your order ID. You can also report a problem with any supplement to the FDA through its MedWatch program. If you stop within the window, the 60-day guarantee still applies to your order.
