The benefits of krill oil should not lead you to believe that dietary supplements can replace a varied and balanced diet and a healthy lifestyle. Be sure to consult your doctor beforehand to ensure this product is suitable for you, especially if you are part of a high-risk group (children, pregnancy, breastfeeding, illness, or ongoing treatment). In all cases, follow the recommended daily doses listed on the packaging. This precaution applies to all dietary supplements, without exception.
Dietary supplements enriched with omega-3 are generally not recommended for people on anticoagulant medication or those preparing for surgery (due to their blood-thinning effect). Krill oil may also be contraindicated for people with type 2 diabetes, as it may reduce insulin sensitivity.
