Compare NatureWise Krill Oil + D3 and Omega-3 + Vitamin E on purity, dosage, and cost. Find which omega-3 supplement fits your health goals.
Quick answer
Choose NatureWise Krill Oil + D3 if you want a smaller dose with vitamin D3 and prefer krill oil's unique absorption profile. Choose NatureWise Omega-3 + Vitamin E if you need high EPA/DHA levels (1000 mg total per serving) with added antioxidant protection and NSF certification.
Why EPA and DHA levels matter most
The primary reason to take an omega-3 supplement is to get enough EPA and DHA — the two fatty acids linked to heart, brain, and immune support. Krill oil naturally contains less EPA and DHA per capsule than fish oil, so you may need more capsules to match the same total. NatureWise Krill Oil + D3 provides 150 mg EPA and 70 mg DHA per serving, while NatureWise Omega-3 + Vitamin E delivers 600 mg EPA and 400 mg DHA per serving — roughly 4.5 times the combined EPA/DHA.
Added vitamins: D3 versus E
Each product adds a different fat-soluble vitamin. Krill Oil + D3 includes 6,000 IU of vitamin D3 per serving, which supports immune function and bone health — a smart addition if you already take a separate D3 supplement or want to combine two nutrients in one softgel. Omega-3 + Vitamin E adds vitamin E as a natural antioxidant that helps protect the delicate omega-3 oils from oxidation, which can extend shelf life and freshness. Your choice depends on whether you prioritize extra vitamin D or prefer built-in freshness protection.
Third-party testing and purity
NatureWise Omega-3 + Vitamin E carries NSF certification, meaning its contents have been independently verified for purity and potency. Krill Oil + D3 does not list NSF certification in its available facts, though it uses Antarctic SuperbaBoost® krill oil — a known source. If third-party certification is a deciding factor, the Omega-3 + Vitamin E offers that extra layer of assurance.
Trade-offs at a glance
- Omega-3 potency: Krill Oil + D3: 270 mg total omega-3 per serving. Omega-3 + Vitamin E: 1000 mg total omega-3 per serving. If you need high EPA/DHA for heart or cognitive support, the fish oil option delivers more per capsule.
- Added vitamins: Krill Oil + D3 adds 6,000 IU vitamin D3. Omega-3 + Vitamin E adds vitamin E as an antioxidant. Choose D3 if you want combined support; choose vitamin E if you prioritize oil freshness.
- Third-party certification: Omega-3 + Vitamin E is NSF certified. Krill Oil + D3 does not list NSF certification in its available facts. NSF certification provides independent verification of purity and potency.
- Price per serving: Krill Oil + D3: USD 20.29 (compare at USD 28.99). Omega-3 + Vitamin E: USD 6.89 (compare at USD 9.99). The fish oil option is significantly more affordable per bottle, especially at larger sizes.
Product facts at a glance
- Krill Oil + D3: Antarctic SuperbaBoost® krill oil with 6,000 IU Vitamin D3, 270 mg Omega-3, 150 mg EPA, 70 mg DHA, made with halal gelatin. Krill oil's phospholipid-bound omega-3s may be absorbed differently than fish oil, and the added vitamin D3 supports immune and bone health in one softgel.
Krill Oil + D3 - Omega-3 + Vitamin E: Fish oil with 1000 mg Omega-3 per serving (600 mg EPA + 400 mg DHA), added Vitamin E, and NSF certification. Higher EPA/DHA per serving means fewer capsules to reach therapeutic levels, and NSF certification confirms independent purity testing.
