Krill Oil and Empagliflozin

Here is the interaction we found between these two, with the evidence behind it.

Moderate

ANTIDIABETES DRUGS

Why this applies to Empagliflozin

Empagliflozin falls under ANTIDIABETES DRUGS — the group Krill Oil interacts with.

Theoretically, taking krill oil with antidiabetes drugs might increase the risk of hypoglycemia.
Some research in animals and humans shows that krill oil might lower blood glucose levels. However, a small study shows that taking krill oil does not reduce blood glucose levels in patients with type 2 diabetes, most of whom were taking antidiabetes drugs.
Severity Moderate Likelihood Possible Evidence B

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the simple version: krill oil isn't changing how your body processes Jardiance (empagliflozin), and it doesn't speed it up or slow it down. The concern is more additive. Both krill oil and empagliflozin can nudge blood sugar a little lower, so taking them together could in theory push your sugar down more than expected.

Honestly, the evidence here is thin and a bit mixed. Some studies hint krill oil lowers glucose, but one study in people with type 2 diabetes (most already on diabetes meds) found no real drop. So I wouldn't lose sleep over it. Just be aware of low-sugar signs like shakiness, sweating, or feeling lightheaded, and check your readings if you start krill oil. Loop in your pharmacist or doctor before adding it so they can keep an eye on things.

From our pharmacist’s overview on the Empagliflozin page

“Almost everything on this page can nudge blood sugar in someone taking empagliflozin (Jardiance) for type 2 diabetes, heart failure, or kidney protection, and two entries deserve genuine caution before anything else. Siberian cocklebur has caused severe low blood sugar in humans and should not be combined with any glucose-lowering medi…”

About Krill Oil

What is Krill Oil?

Krill Oil
  • Heart and cholesterol support
  • High triglycerides
  • Joint pain and inflammation
  • Brain and eye health
  • PMS symptoms
  • General omega-3 supplementation

Krill oil is a source of omega-3 fatty acids (EPA and DHA) bound to phospholipids, which may help absorption. It is most studied for lowering triglycerides and supporting heart health, but the evidence for many other uses is limited. It is generally well tolerated, but people with shellfish allergy should avoid it, and anyone pregnant, breastfeeding, or on blood thinners should check with a pharmacist or doctor first.
