Malic Acid and Lisinopril

Here is the interaction we found between these two, with the evidence behind it.

Moderate

ANTIHYPERTENSIVE DRUGS

Why this applies to Lisinopril

Lisinopril falls under ANTIHYPERTENSIVE DRUGS — the group Malic Acid interacts with.

Theoretically, malic acid might increase the risk of hypotension when taken with antihypertensive drugs.
Animal research shows that malic acid isolated from tagetes roots can reduce mean arterial blood pressure.
Severity Moderate Likelihood Possible Evidence D

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the gist with malic acid and lisinopril. Lisinopril already lowers your blood pressure, and there's a theory that malic acid might nudge it down a little further. If that happened, you could feel the usual signs of blood pressure dropping too low, like lightheadedness, dizziness when you stand up, or feeling unusually tired.

I want to keep this in perspective, though. This concern comes only from animal research and how the chemistry looks on paper, not from real studies in people. The malic acid in foods like apples is almost certainly nothing to worry about. With concentrated supplement doses (often paired with magnesium, which can also relax blood vessels), it's worth a quick chat with your pharmacist or doctor before starting.

About Malic Acid

What is Malic Acid?

Malic Acid
  • Fibromyalgia symptoms
  • Muscle pain and fatigue
  • Dry mouth (used in some lozenges)
  • Skin exfoliation (topical)
  • Flavoring and food additive

Malic acid is a natural acid found in apples and other fruits, often combined with magnesium in supplements marketed for fibromyalgia and muscle pain. The evidence for its health benefits is weak and limited, and it is mostly used as a food flavoring. It is generally well tolerated in food amounts, but talk to your pharmacist or doctor before using supplement doses.

About Lisinopril

What Is Lisinopril Used For?

Brand names: Zestril, Prinivil, Qbrelis

Lisinopril treats high blood pressure (hypertension) in adults and children 6 years and older, and can be used alone or alongside other blood pressure medicines. Lowering blood pressure reduces the risk of strokes and heart attacks. The tablet combination product containing lisinopril and hydrochlorothiazide is specifically indicated for high blood pressure.

Lisinopril is also used as an add-on therapy to reduce signs and symptoms of systolic heart failure, and to reduce the risk of death in people who are hemodynamically stable (have reasonably stable circulation) within 24 hours of an acute heart attack (acute myocardial infarction).
