How Does Krill Oil Support Joint Health Differently? +

Traditional fish oil delivers omega-3s in triglyceride form — your body has to break them down with bile salts before they can be absorbed. Most of those nutrients never make it to your joints.

Krill oil delivers the same omega-3s (EPA and DHA) bound in a phospholipid complex. Because your own cell membranes are made of phospholipids, the nutrients are recognized by your cells, absorbed directly, and transported into joint tissue — without the digestive breakdown that limits fish oil.

That's also why there are no fishy burps or stomach upset.

How Long Before I Notice a Difference? +

Most people start to notice changes in morning stiffness and everyday joint comfort within the first 2-4 weeks. Results tend to improve steadily through the first 90 days of consistent daily use.

What’s Included? +

Each bottle contains softgel capsules of pure Antarctic Krill Oil with naturally occurring Astaxanthin.

Every batch is sourced from sustainably harvested Antarctic krill and tested for purity, potency, and heavy metals.

Is It Right For Me? +

This formula was designed for adults dealing with persistent joint stiffness and discomfort — especially those who've been through a lot and haven't found something that works. If you've tried fish oil and gave up because of the taste, stomach issues, or lack of results — this is worth trying. If NSAIDs bother your stomach, or you're looking for a natural way to support your body's inflammatory response — this was made for you.

Consult your healthcare provider before use if you have a shellfish allergy or are taking blood-thinning medication.

I started taking these about 5 weeks ago. The first thing I noticed was that I wasn't waking up as much at night from that dull ache in my knee. By week 3, the morning stiffness was noticeably less. I wish I'd found this sooner.

Why Your Knee Can Still Feel Stiff

Why Your Knee Can Still Feel Stiff Even When the Surgery Went Well

The damaged joint was replaced. But the tissues surrounding it still need daily support.

Your surgeon corrected the structural problem.

The implant is in place. The X-ray may look good. Yet months later, your knee can still feel stiff when you stand up, swollen after activity, or painful when you turn over in bed.

That is because replacing the joint does not instantly settle everything around it.

The joint capsule, muscles, tendons and surrounding tissues have been through surgery, reduced movement and months of recovery. When that environment remains irritated, even normal activities can leave the knee feeling tight, heavy and difficult to move.

This is where the form of your omega-3 matters.

Most standard fish oil carries EPA and DHA mainly in triglyceride form. Krill oil naturally carries much of its omega-3 content in phospholipids—fat structures similar to those found in cell membranes.

Research suggests this phospholipid form can produce stronger increases in circulating EPA and DHA than comparable fish-oil formats, helping your body make better use of the omega-3s you take. 

Persa also naturally contains astaxanthin, an antioxidant that helps protect against oxidative stress. Together, these nutrients support:

  • A healthy inflammatory response
  • Joint comfort and flexibility
  • Easier movement after sitting or resting
  • Recovery from everyday activity
  • Heart and brain health

It is not another temporary numbing approach. It is daily nutritional support for the environment surrounding your recovering knee.

For The Mornings That Start With Stiffness

For The Mornings That Start With Stiffness And The Nights That End With Aching

After joint surgery, you expected to get your life back. Instead, you got a new kind of pain that greets you every morning — and a dull, persistent ache that keeps you up at night.

The simplest things feel harder than they should. A walk through the store. Stairs. Getting up from the couch. You push through it because that's who you are — but privately, you're wondering if this is just how it is now.

It doesn't have to be.

One reason your joint may still feel this way is that the inflammatory response inside the joint tissue was never addressed at the cellular level. The surgery was a structural success. But deep inside the joint, oxidative stress and enzyme activity may still be working against your comfort — and everything you've tried so far may not have been able to reach it.

Antarctic Krill Oil with Astaxanthin delivers targeted omega-3 support directly into joint tissue through its natural phospholipid structure — helping to support a healthy inflammatory response, ease everyday stiffness, and promote the cellular environment your joint needs to feel better.

Simple Enough For The Routine

Simple Enough For The Routine You Already Have

When you're dealing with joint discomfort, the last thing you need is a complicated supplement routine.

Persa keeps it simple: Take 1-2 small soft gels daily with water, preferably with a meal.

No fishy taste. No stomach upset. No handfuls of pills. Just one small step each day to support your joints at the cellular level.

Pure Antarctic Krill Oil with Astaxanthin — one simple step for daily joint support.

Frequently Asked Questions

Simple answers about how Persa works, how to take it, and why it's different.

How Does Krill Oil Actually Work for Joint Comfort? +

Krill oil delivers omega-3 fatty acids (EPA and DHA) bound in phospholipids — the same structural building block your cell membranes are made of. This means the nutrients are recognized by your cells and absorbed directly into joint tissue, rather than being broken down by bile salts in digestion like standard fish oil.

Once inside the joint tissue, the omega-3s help support a healthy inflammatory response by influencing the enzymes involved in cartilage maintenance. The naturally occurring astaxanthin provides additional antioxidant protection at the cellular level.

Studies show that Krill Oil daily reduced C-Reactive Protein (an inflammatory marker) by 19.3% in 7 days and nearly 31% in 30 days.

Is Persa a stimulant? +

No, krill oil is not a stimulant. It is a natural marine lipid — a food-derived source of omega-3 fatty acids with antioxidant support.

However, because omega-3s may have a mild effect on blood clotting, you should consult your healthcare provider before use if you are taking blood-thinning medication (such as warfarin or aspirin therapy). Also consult your provider if you have a known shellfish allergy.

I've had joint surgery. Is this safe to take during recovery? +

Krill oil is a dietary supplement, not a medication. It delivers naturally occurring omega-3 fatty acids and astaxanthin to support your body's normal inflammatory response and joint comfort.

How long before I notice a difference? +

Based on clinical research, measurable changes in inflammatory markers begin within the first 7 days. Most people begin to notice improvements in everyday joint comfort — particularly morning stiffness and discomfort after activity — within 2 to 4 weeks of consistent daily use.

Results continue to improve through 90 days of consistent use. This is not a stimulant or a pain masker — it supports your body's cellular environment, and that takes some time to compound.
