Buying Guide
What should you consider when choosing an Antarctic krill oil with astaxanthin?
- Potency per serving: Higher mg can reduce the number of capsules you take daily but may increase the chance of digestive sensitivity. Balance efficiency with tolerance.
- Astaxanthin content: Acts as an antioxidant and helps stabilize the oil. A higher astaxanthin level can offer extra stabilization but verify actual amounts on the label.
- Source and purity: Look for krill sourced from Antarctic waters and products that are non-GMO, gluten-free, and tested for heavy metals to ensure purity.
- Form and absorption: Krill oil’s phospholipid-bound omega-3s often lead to better absorption and fewer fishy aftertastes compared with traditional fish oil.
- Combination with fish oil: Some formulas add fish oil for broader EPA/DHA coverage. Consider your dietary needs and tolerance to fishy flavors.
- Capsule count and daily dose: A bottle with more capsules may offer better long-term value if you prefer fewer capsules per day.
