Why Choose PRN Instead of Ordinary Fish Oil?
1. It's What's Inside the Capsule That Matters
Many fish oil supplements prominently advertise 1,000 mg of fish oil per capsule. But that number does not tell you how much EPA and DHA you're actually receiving.
EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid) are the key marine omega-3 fatty acids widely studied in nutrition, inflammation and ocular health.
PRN emphasizes concentrated EPA and DHA rather than simply total fish oil content.
The important comparison is not the size of the capsule. It's the amount of EPA and DHA it contains.
2. Premium Triglyceride-Form Omega-3
Not all fish oils are supplied in the same chemical form.
PRN uses triglyceride-form fish oil, including re-esterified triglycerides in its De3 formulation.
Some comparative studies have reported better omega-3 absorption from triglyceride-form oils than from ethyl-ester preparations under specific conditions.
Although absorption also depends on diet and individual factors, the formulation is worth considering when choosing an omega-3 supplement.
3. Developed With Eye Health in Mind
PRN has a particular focus on omega-3 supplementation within eye care.
Its re-esterified formulation has been investigated in published clinical research involving patients with dry eye disease and meibomian gland dysfunction.
Why Dr. Morris Recommends PRN Omega-3
"When patients ask me about Omega-3 supplements, I always encourage them to look beyond the glossy label.
Many supplements promote the total amount of fish oil without clearly emphasizing the actual EPA and DHA content. Those concentrations can vary considerably between products.
What I appreciate about PRN is the concentration of EPA and DHA, its triglyceride formulation and its focus on ocular health.
I have recommended PRN in clinical practice for years. It is a great option for patients interested in premium nutritional supplementation. As with all supplements, individual needs vary, and omega-3 should not be considered a replacement for appropriate dry eye diagnosis or treatment.
For patients considering a quality supplement, PRN is certainly a brand I believe deserves strong consideration."

Omega-3 for Dry Eye: What Does the Latest Clinical Research Say?
Omega-3 Supplementation in TFOS DEWS III (2025)
The Tear Film & Ocular Surface Society (TFOS) published its updated international dry eye management recommendations in 2025.
The TFOS DEWS III Management and Therapy Report recognizes dietary supplementation as an important consideration in dry eye management and reviews the growing evidence concerning omega-3 fatty acids.
The report highlights clinical research showing that omega-3 supplementation may improve several measures of dry eye disease, including:
- Tear breakup time (TBUT)
- Tear osmolarity
- Schirmer tear production measurements
- Patient-reported dry eye symptoms
- Conjunctival goblet cell density
Importantly, DEWS III cites a meta-analysis of 19 randomized controlled trials reporting statistically significant improvements in dry eye signs and symptoms with omega-3 supplementation.
Although not every study has demonstrated a benefit, the international consensus report continues to recognize a potential role for omega-3 fatty acids as part of individualized dry eye management.
PRN Omega-3: A Formulation Studied in Dry Eye Patients
A 2016 randomized, double-masked clinical trial published in Cornea specifically investigated a PRN re-esterified triglyceride omega-3 formulation in patients with dry eye disease and meibomian gland dysfunction.
Participants receiving omega-3 supplementation demonstrated statistically significant improvements compared with controls in tear osmolarity, tear breakup time and patient-reported dry eye symptoms over 12 weeks.
The study provides encouraging evidence concerning the particular formulation and clinical population investigated.
Why the Type of Omega-3 Matters
Fish oil supplements vary considerably in their concentrations of EPA and DHA, chemical form and recommended serving sizes.
PRN De3 and PRN Oe Liquid provide concentrated EPA and DHA in triglyceride-form formulations.
For individuals considering omega-3 supplementation as part of their eye-care routine, understanding these differences is an important part of making an informed choice.
Dr. Morris's perspective: Both supplementation and increased intake are options worth considering as part of a comprehensive dry eye management plan. Supplementation is often required to achieve the levels required for effect but should be used alongside, rather than replacing, appropriate diagnosis, lubricating drops, lid hygiene and other treatments when indicated.

Frequently Asked Questions About PRN Omega-3
What makes PRN Omega-3 different from regular fish oil?
PRN emphasizes concentrated EPA and DHA in premium triglyceride-form fish oil. When comparing omega-3 products, it's important to examine the actual EPA and DHA amounts per serving rather than relying solely on total fish oil content.
Can PRN Omega-3 help with dry eyes?
Some clinical studies involving omega-3 supplementation have reported improvements in dry eye signs and symptoms. However, other high-quality studies have not found significant benefits compared with placebo. Results vary, and omega-3 supplementation should not replace appropriate dry eye treatment.
How much EPA and DHA does PRN De3 contain?
The current De3 product provides 1,680 mg EPA and 560 mg DHA per labelled three-softgel serving, for a total of 2,240 mg EPA and DHA.
Is PRN liquid as concentrated as PRN De3?
Yes. The two products provide the same stated EPA and DHA amounts per labelled serving: three De3 softgels or 5 mL of PRN Oe Liquid.
How long does a bottle last?
A 180-softgel De3 bottle provides 60 three-softgel servings. A 200 mL liquid bottle provides 40 servings of 5 mL each.
The actual duration depends on the daily dosage recommended for you. Follow the current product label or your healthcare professional's instructions.
Is PRN Omega-3 better absorbed than other fish oils?
Triglyceride and re-esterified triglyceride fish oils have demonstrated absorption advantages over some ethyl-ester formulations in certain studies. However, bioavailability also depends on meal composition, dose and individual physiology. Higher absorption does not necessarily establish better clinical outcomes for dry eye.
Can I take PRN Omega-3 with my dry eye drops?
Nutritional supplements and eye drops serve different purposes. They may both form part of an individualized eye-care regimen. Consult your optometrist about which treatments are appropriate for your particular condition.
