What it is
Docosahexaenoic acid (DHA) is a long-chain omega-3 fatty acid that constitutes over 50% of photoreceptor membrane phospholipids. DHA-dominant fish oil prioritizes DHA over EPA for retinal structural support.

How it works
DHA maintains photoreceptor membrane fluidity, supports rhodopsin function, and serves as a precursor for anti-inflammatory resolvins and neuroprotectins. For dry eye, DHA may improve meibomian gland lipid quality and tear film stability, though large RCTs (DREAM study) showed no significant symptom improvement versus placebo.
Who should take it
Adults with dry eye symptoms, meibomian gland dysfunction, or family history of AMD seeking dietary DHA supplementation.
Avoid / careful
Avoid if you have fish allergy or bleeding disorders. Discontinue 1 week before surgery due to antiplatelet effects. High doses may increase atrial fibrillation risk.

FAQs
Frequently asked
How long until DHA (Eye) starts working?
Most supplements show effects in 2-8 weeks of consistent daily use. Notable effects from DHA (Eye) typically appear within this window, though individual response varies based on baseline status, dose, and underlying biochemistry.
When should I take DHA (Eye)?
DHA (Eye) works best taken morning or evening, ideally with food. Typical dose: 1,000 mg DHA/day from fish oil. Consistency over time matters more than perfect timing.
Is DHA (Eye) safe to take long-term?
For most adults, yes — with the cautions noted: Avoid if you have fish allergy or bleeding disorders. Discontinue 1 week before surgery due to antiplatelet effects. High doses may increase atrial fibrillation risk.. Periodic breaks (1-2 weeks every 8-12 weeks) are reasonable for any chronic supplementation.
Is DHA (Eye) available in India and what should I look for when buying?
DHA (Eye) is widely available on Amazon India and in supplement stores in major cities. Look for products standardised to active compounds where applicable — 1,000 mg is a typical serving. Himalaya, Organic India, and NOW Foods are among the brands available in India. Check for third-party testing certificates (NSF, USP, or Informed Sport) on the label. Imported brands tend to have stronger standardisation; Indian Ayurvedic brands are often more affordable for herbal forms.
How do I know if DHA (Eye) is actually working?
The best way to track DHA (Eye)'s effect is to note the specific symptoms you're addressing — and recheck relevant blood markers at 8–12 weeks. Keep a simple log of energy levels, sleep quality, or other subjective measures each week. If you're using it for blood marker improvement (TSH, ferritin, LDL etc.), compare before and after values. Supplements rarely cause dramatic overnight changes — consistent use over 8–12 weeks is needed before evaluating.
