XanthOmega Krill Oil Review by Designs for Health - Dr. Bell

A 54-year-old man came to me wanting to support his heart. His cholesterol was borderline, his triglycerides were a bit high, and his doctor had suggested omega-3s. He had tried fish oil before but quit because of the fishy aftertaste and the repeating "fish burps" that he found genuinely unpleasant. He wanted the cardiovascular benefits of omega-3s without the side that had driven him off them last time.

This is a perfect situation for krill oil. Krill oil delivers the same key omega-3s as fish oil (EPA and DHA), but in a different chemical form that tends to absorb well and, for many people, comes without the fishy repeat. I started him on XanthOmega Krill Oil, and he was able to take it daily with none of the aftertaste that had been the dealbreaker before. Over a few months his triglycerides improved alongside his other changes.

Omega-3 fats are among the most well-supported supplements for heart and overall health, and the main barrier for a lot of people is simply tolerating them. XanthOmega Krill Oil is the form I reach for when someone wants high-quality omega-3s, has struggled with fish oil burps, or wants the extra antioxidant that krill naturally provides.

What this product is actually doing

The two omega-3 fats that matter most, EPA and DHA, support the cardiovascular system in several ways: they help keep triglycerides in a healthy range, support healthy blood vessel function, and have a calming effect on the body's inflammatory processes. They are also crucial for the brain, where DHA is a major structural fat, and they support joint comfort. Most people simply do not get enough from diet unless they eat fatty fish regularly.

The interesting thing about krill oil is the form the omega-3s come in. In fish oil, EPA and DHA are mostly attached to triglycerides; in krill oil, a large share is bound to phospholipids, the same kind of fat that makes up your cell membranes. Many people find this phospholipid form absorbs well and sits more comfortably in the stomach, which is the practical reason it tends not to cause the fishy repeat.

Krill oil also comes with a natural bonus: astaxanthin, a red antioxidant that gives krill its color. Astaxanthin helps keep the delicate omega-3 fats from oxidizing and adds its own antioxidant support. XanthOmega delivers EPA and DHA in this naturally phospholipid-bound, astaxanthin-protected form.

What is in XanthOmega Krill Oil

The formula centers on krill-sourced omega-3s:

• EPA and DHA omega-3s from krill (the heart- and brain-supporting fats)
• Naturally bound phospholipids (the form many people absorb well and tolerate without fishy burps)
• Astaxanthin (a natural antioxidant from krill that protects the oils and adds its own benefit)
• Sustainably sourced krill oil (from a small, low-on-the-food-chain crustacean)

The phospholipid form is the genuine differentiator from standard fish oil, and it is why I reach for krill specifically for people who could not tolerate fish oil. The naturally included astaxanthin is a nice extra, since it both stabilizes the product and contributes antioxidant support. Krill also sits very low on the food chain, which generally means low accumulation of the contaminants that concern people about larger fish.

Who tends to do well on XanthOmega Krill Oil

The pattern that responds best:

• People wanting cardiovascular support, especially with borderline or high triglycerides
• Anyone who quit fish oil because of fishy burps or aftertaste
• Those who want omega-3s for brain, mood, or joint support as well as the heart
• People who do not eat fatty fish regularly
• Anyone who prefers a smaller, well-absorbed omega-3 with a built-in antioxidant
• Those concerned about contaminants who like krill's low position on the food chain

Who should skip it

• People with a shellfish allergy (krill is a crustacean; this is the important one)
• Those on blood thinners or with a bleeding disorder, without provider input (omega-3s have a mild blood-thinning effect)
• Anyone scheduled for surgery within two weeks (stop and tell your surgeon)
• People who already eat plenty of fatty fish and may not need to supplement
• Pregnant or breastfeeding women, without provider guidance on dose and source

How to take it

Take the label dose daily, with a meal that contains some fat.

• Take it with food, ideally a meal with some fat, which improves absorption of these fat-soluble omega-3s.
• If you are targeting triglycerides specifically, talk with your provider about whether a higher omega-3 dose is appropriate, since therapeutic doses can be higher than a maintenance dose.
• Be consistent. Omega-3 levels in your tissues build over weeks to a few months.
• Store it as directed; the astaxanthin helps protect the oil, but omega-3s still keep best away from heat and light.

What to expect

• First days to weeks: most people notice it is easy to take, with no fishy repeat
• Weeks 4 to 12: triglyceride and other cardiovascular markers can improve, alongside diet and lifestyle
• Over months: omega-3 tissue levels build, supporting heart, brain, and joints
• This is foundational support; the benefits are protective and cumulative rather than immediately felt

Side effects

• Much less fishy repeat than fish oil for most people, though not always zero
• Mild digestive upset or loose stools in some people, especially at higher doses
• A mild blood-thinning effect (relevant if you are on anticoagulants or facing surgery)
• Allergic reaction in anyone with a shellfish allergy

What I do not love about it

The shellfish-allergy issue is the one I never let slide. Krill is a crustacean, so anyone with a shellfish allergy should not take krill oil and should use a non-shellfish omega-3 instead. It is an easy detail to overlook because people think of krill as "fish oil," but it is not, and the distinction matters for allergy safety.

Krill oil also tends to be more expensive per gram of EPA and DHA than standard fish oil. The phospholipid form and the astaxanthin are real advantages, but if someone tolerates fish oil fine and is dosing for high triglycerides, plain fish oil can deliver more omega-3 per dollar. I reach for krill specifically when tolerability or the absorption form is the priority, not as a default for everyone.

And the per-capsule omega-3 amount in krill products is often lower than in concentrated fish oils, so reaching a higher therapeutic dose can take more capsules or simply not be practical with krill alone. For someone who needs a large omega-3 dose to manage significantly elevated triglycerides, I sometimes use a concentrated fish oil instead and reserve krill for general support and easy tolerability.

For background, see the PMC review on omega-3s and cardiovascular health, the PMC review on krill oil absorption and the phospholipid form, and the NIH Office of Dietary Supplements fact sheet on omega-3 fatty acids.

Bottom line

XanthOmega Krill Oil is the omega-3 I reach for when someone wants heart, brain, and joint support but has struggled with the fishy burps of fish oil. The krill-sourced EPA and DHA come in a phospholipid form many people absorb well and tolerate comfortably, with natural astaxanthin as an antioxidant bonus. Take it daily with a meal that has some fat.

Always check with a healthcare provider before starting any new supplement, especially if you have a shellfish allergy, take blood thinners, or have surgery scheduled.
