Best Supplements for Red Eyes

By Elise

Red eyes are a common symptom that can be caused by dryness, allergies, eye strain, or irritation. In some cases, they may also be linked to infections or inflammation. While red eyes are often temporary, they can be uncomfortable, affect appearance, and interfere with daily activities—especially if accompanied by itching, burning, or blurred vision.

Alongside medical evaluation to determine the underlying cause, natural supplements can help reduce inflammation, support eye health, and protect delicate eye tissues. Here are two evidence-based options that may provide gentle, supportive relief.

Omega-3 Fatty Acids

Omega-3 fatty acids, commonly found in fish oil, play a key role in eye moisture and inflammation control. They can help reduce redness caused by dry eyes or irritation by supporting the production of healthy tears and reducing inflammation in the eye’s surface tissues.

  • Mechanism of action: Supports tear film production, reduces inflammation, and promotes healthy eye cell membranes.
  • Dosage or usage tip: Typical dose is 1,000–3,000 mg of combined EPA and DHA daily.

Vitamin C

Vitamin C is a powerful antioxidant that helps protect the eyes from oxidative stress and supports healthy blood vessels. It may help reduce redness by promoting tissue repair and reducing inflammation in and around the eyes.

  • Mechanism of action: Neutralizes free radicals, supports collagen production for healthy eye tissues, and strengthens capillaries.
  • Dosage or usage tip: Commonly taken at 500–1,000 mg daily, divided into two doses for better absorption.
