Protoflow and Alcohol: Can You Drink While Taking It?

No: the label gives no warning or permission about alcohol.

That silence is not a clearance. Labels do not list every interaction, and the label's only medical advice is to consult a physician prior to use if you take any medication. Alcohol is a drug in the pharmacological sense, so treat it as you would any other substance that can interact.

High-dose niacin has been linked to liver problems, and alcohol adds its own load, so heavy drinkers should be careful.

NIH notes that liver toxicity is a risk at high doses of niacin, particularly of slow-release forms (NIH ODS, Niacin). The label gives 75 mg and no form. If you drink heavily, have liver disease, or take medicines that affect the liver, ask your doctor before starting Protoflow. Stop and seek care for yellow skin or eyes, dark urine or severe stomach pain.

It adds noise, because an evening of drinks can change your night-time urination far more than a capsule would.

If you want to learn whether Protoflow does anything, keep your drinking steady, and note each drink in the diary. A sudden rise or fall in alcohol will swamp any small effect. Many men find that cutting evening alcohol alone reduces night trips, which is worth knowing whatever you take.

• Keep your usual intake steady, or cut back
• Avoid alcohol for two hours either side of the dose
• Do not drink to relieve a flush
• Note each drink in the diary

If you cannot keep to a steady pattern, write that down so you can read the results fairly.
