Does Prime Perform work? What the evidence covers

What it is meant for

The maker positions Prime Perform as a daily formula for men's vitality. Like every supplement, it is not intended to diagnose, treat, cure or prevent any disease, and it is not a substitute for medicine.

What is known about the ingredients

• Tongkat ali (Eurycoma longifolia): a Southeast Asian root studied in small trials in men, mostly on hormone levels, stress and wellbeing, with mixed results. Prime Perform has 10 mg of a 100:1 extract.
• Epimedium (horny goat weed): contains icariin; most of the research is in the lab or in animals, with little data in people.
• Saw palmetto: much of the research used around 320 mg of extract a day, mainly on urinary comfort in older men, with mixed results. Prime Perform has 20 mg.
• Nettle, wild yam and sarsaparilla: traditional botanicals with limited research in people.
• Boron: a trace mineral; a few small studies have looked at boron and hormone markers.

These findings are about single ingredients, often at other amounts. They do not show what Prime Perform as a product does.

What it cannot do

Prime Perform does not replace a diagnosis or prescribed treatment. If you have ongoing concerns about your health, energy or sexual health, see a doctor: those issues can be linked to heart health, blood pressure, blood sugar or medication, which deserve a proper check-up.

How to take it

Two capsules a day with an 8 oz. glass of water, as printed on the label. Do not exceed that amount. One bottle lasts 30 days, and the 60-day guarantee gives you time to judge it calmly.
