Protoflow and Liver Health

Because the liver processes most supplements and drugs, and herbal products are a known cause of liver injury.

The NIH keeps a database of liver injury from drugs and supplements, and herbal and dietary products form a growing share of cases. Most supplement users never have a problem, but the few who do can become seriously ill. Knowing the signs allows early action.

High doses, usually hundreds to thousands of milligrams a day, can raise liver enzymes and cause hepatitis.

NIH warns that slow-release forms carry more risk and that people with liver disease should avoid high doses (NIH ODS, Niacin). Protoflow's 75 mg is far below the usual range of concern, but it is above the 35 mg upper limit, and the form is unstated. Together with other niacin sources, the total might climb. Count them.

• Yellow skin or eyes
• Dark urine or pale stools
• Pain in the upper right abdomen
• Unusual tiredness, nausea or loss of appetite
• Itching all over without a rash

Stop the capsules and see a doctor the same day. Tell the clinician what you took, with the label.

Statins, some antibiotics, paracetamol in large amounts and other drugs affect the liver, so the load adds up.

A pharmacist can review the combination. Niacin plus a statin is a known combination that requires care, since both can affect the liver and muscles. If you take a statin, ask before the blend and report any muscle pain or dark urine.

Risk is low at the label dose for most men, higher for those with liver disease or heavy drinking.

Know the signs, count your niacin and ask a doctor if you are in a risk group.
