Dry eye isn’t just a surface-level nuisance. It often signals a deeper deficiency in the omega-3s your body uses to build a healthy, stable tear film. Standard fish oil can help, but its absorption is poor, and the fishy burps are a dealbreaker for many. Krill oil delivers those critical fatty acids in a phospholipid form that your cells actually use, and the built-in antioxidant astaxanthin helps keep the oil stable and effective.
I’m Mohammad — the founder and writer behind ProteinJug. I have spent years dissecting supplement labels, analyzing clinical studies on omega-3 bioavailability, and cross-referencing third-party testing results to separate marketing from medicine. This guide focuses exclusively on krill oil’s specific benefits for dry eye relief, not generic heart health claims.
After comparing potency, purity, dosage forms, and real user feedback, I’ve narrowed the field to the five krill oil supplements that consistently earn their spot. choose the right formulation for lasting dry eye relief with this best krill oil for dry eyes guide.
How To Choose The Best Krill Oil For Dry Eyes
Not all krill oils are created equal. The right one for dry eyes hinges on three factors: the molecular delivery system, the purity of the source, and the total EPA/DHA payload you can sustain daily without side effects. Here’s what matters most.
Phospholipid Bioavailability
Krill oil’s omega-3s are primarily bound to phospholipids, not triglycerides like in standard fish oil. This structure bypasses a key enzymatic step in digestion, meaning the EPA and DHA head straight to your bloodstream and cell membranes, including the meibomian glands that produce the oily layer of your tear film. If a krill oil doesn’t disclose its phospholipid content, look elsewhere.
Astaxanthin Content
Astaxanthin is the natural red pigment that gives krill its color. It is a potent antioxidant that protects the delicate omega-3 fatty acids from oxidation inside the bottle and inside your body. For dry eye, this matters because oxidative stress is a known contributor to meibomian gland dysfunction. A higher astaxanthin level means a more stable oil with greater anti-inflammatory potential.
Serving Size and EPA/DHA Per Capsule
Most dry eye protocols recommend a combined daily intake of 1500–2000 mg of EPA/DHA. You need to know exactly how much EPA and DHA each softgel delivers, and how many capsules you are willing to swallow per day. A 1000 mg krill oil softgel may only provide about 250 mg of combined omega-3s, so calculate your daily dose before buying.

In‑Depth Reviews
1. ONNIT Antarctic Krill Oil
ONNIT delivers 1000 mg of krill oil per serving, providing a solid dose of phospholipid-bound EPA and DHA that your meibomian glands can actually use. The inclusion of astaxanthin and natural phospholipids gives it a clear edge over basic fish oil for dry eye support. The softgels are smaller than average and easy to swallow, and the Marine Stewardship Council certification confirms the source is responsibly wild-caught.
User feedback frequently highlights a noticeable reduction in joint stiffness and overall body pain after consistent use, which aligns with the anti-inflammatory profile needed for ocular surface health. The oil has a distinct scent when the bottle is opened, but no one reports the dreaded fishy burps. The IGEN certification adds a layer of trust for those who worry about hidden contaminants.
The primary drawback is the bottle size: 60 softgels at two per day (1000 mg total) lasts only one month. If you are aiming for a higher therapeutic EPA/DHA dose, you will need to double up, which doubles the monthly cost. Still, for a premium, highly bioavailable krill oil, ONNIT is the clear frontrunner for daily dry eye management.
Why it’s great
- High bioavailability with phospholipid-bound omega-3s
- IGEN Non-GMO Tested for purity
- No fishy aftertaste or burping
Good to know
- Has a noticeable krill scent when opening
- One bottle lasts one month at recommended dose
2. NovaKrill Krill Oil
NovaKrill is formulated specifically to avoid the gastrointestinal side effects that send people running from fish oil. Each serving of two softgels provides 1000 mg of Antarctic krill oil, including EPA, DHA, and astaxanthin. The astaxanthin is a nice bonus for protecting the oil from oxidation and may offer additional support against the oxidative stress that worsens dry eye symptoms.
The softgels are noticeably small and smooth, making them easy to swallow even for people who struggle with larger capsules. Users consistently mention zero fishy aftertaste and no burping, which is the single biggest reason krill oil outperforms fish oil for everyday compliance. If you have a sensitive stomach or a strong aversion to fish flavors, NovaKrill is your likely daily driver.
One minor issue is that the bottle has a faint krill scent when first opened, but this fades quickly and does not affect the taste or aftertaste. The 60-count bottle at two softgels per day runs a full month, making it easy to track your consumption. It’s a very clean, user-friendly option for anyone wanting to test krill oil for dry eyes without committing to a huge bottle.
Why it’s great
- Absolutely no fishy burps or aftertaste
- Small, smooth softgels that are easy to swallow
- Contains astaxanthin for antioxidant protection
Good to know
- Slight scent when the bottle is first opened
- Standard 60 count lasts one month
3. Kirkland Signature Krill Oil
Kirkland Signature carries the USP Verified mark, which means independent testing has confirmed the supplement actually contains what the label claims and is free from harmful contaminants. Each softgel delivers 500 mg of pure krill oil, and the instruction is a single softgel per day. That simplicity is a big advantage for anyone who finds daily supplement routines difficult to maintain.
The softgels are small, easy to swallow, and have no strong odor when the bottle is sealed. Most users report no aftertaste and no fishy burps, which is consistent with the quality of the USP program. The value per bottle is strong given the 160-count size, which provides over five months of daily use—unusual for a krill oil product at this price tier.
The trade-off is the lower per-serving dose. At 500 mg total (likely around 125 mg combined EPA/DHA), you are getting a maintenance dose rather than a therapeutic dose for active dry eye management. If you have mild symptoms or just want general support, this is perfect. For more severe dryness, you may need to take two or even three softgels to reach the effective range.
Why it’s great
- USP Verified for ingredient accuracy and purity
- Excellent value with 160 softgels per bottle
- Easy, one-softgel daily routine
Good to know
- Lower per-serving omega-3 dose (maintenance level)
- Some users report a moderate scent
4. Natures Craft Antarctic Krill Oil
Natures Craft packs 240 softgels into one bottle, making this the highest count option on the list. Each softgel provides 500 mg of Antarctic krill oil, so a daily dose of two softgels (1000 mg total) still gives you four months of supply. The label specifically calls out the presence of astaxanthin, EPA, and DHA, and the phospholipid structure is implied in the krill oil itself.
User feedback is notably positive from older adults, with one long-term user reporting zero body pain after three years of daily use. The capsules are described as easy to swallow despite their size, and there is no reported fishy aftertaste or burping. For dry eye, this sustained anti-inflammatory effect over months is exactly what the science suggests is needed to rebuild the tear film.
The only real concern is the softgel size: some people with smaller swallows may find them slightly large, though most adapt quickly. The company does not disclose the exact EPA/DHA breakdown per capsule, so you are relying on the 500 mg krill oil specification. For the price per bottle and long supply, this is an excellent choice if you plan to commit to krill oil for several months.
Why it’s great
- Massive 240-count bottle provides months of supply
- No fishy aftertaste or burping
- User reports show consistent long-term benefits
Good to know
- Capsules are on the larger side
- Exact EPA/DHA mg not listed per serving
5. Nutricost Krill Oil 1000mg
Nutricost uses Superbakrill, a branded krill oil ingredient that standardizes the phospholipid content, meaning you are getting consistent absorption from batch to batch. Each serving of 1000 mg (two softgels) delivers a good baseline of EPA and DHA for dry eye support. The price point makes it easy to try krill oil for a month or two without a large financial commitment.
Users consistently mention the absence of fishy taste and burps, and several note improvements in joint pain and elbow discomfort within weeks. The softgels are made in a GMP-compliant, FDA-registered facility, so the manufacturing quality is solid. For someone new to krill oil, Nutricost offers a low-risk entry point with reliable ingredient sourcing.
The 60-count bottle at two softgels per day lasts exactly one month. If you find that krill oil helps your dry eyes, you will be ordering a refill every 30 days, which can add up over time. The capsules also have a slight scent when the bottle is opened, though nothing compared to standard fish oil. It is a straightforward, no-frills option for getting started.
Why it’s great
- Superbakrill ensures consistent phospholipid content
- GMP compliant and FDA registered facility
- No fishy burps or aftertaste for most users
Good to know
- 60 count means monthly refills
- Slight krill scent when bottle is opened
