Best Fish Oil Supplement of 2025
Fish oil supplements are like dating – there’s a ton of options, but the good ones are hard to find.
I’ve spent hours researching the top 5 fish oil supplements so you don’t have to.
Let’s dive in (fish pun intended).
Sports Research Triple Strength Omega-3 Fish Oil
1250 mg per softgel, wild Alaskan pollock source, 90 count
Triple Strength Omega 3 Fish Oil (Mystery Brand)
3600 mg per serving with 1300 mg EPA + 860 mg DHA, 120 count
Micro Ingredients Triple Strength Omega 3
4200 mg per serving, 240 softgels, lemon-flavored, 1200 mg EPA + 900 mg DHA
Viva Naturals Omega 3 Fish Oil Supplement
2500 mg triple strength, 30 softgels, high EPA (1400 mg) and DHA (480 mg)
1. Sports Research Triple Strength Omega-3 Fish Oil
1250 mg per softgel, wild Alaskan pollock source, 90 count
What’s Good:
- Comes from wild Alaskan pollock (single source = more consistent quality)
- No fishy burps (hallelujah!)
- Third-party tested and MSC certified sustainable
What’s Not:
- Contains fish gelatin, so not for the vegans out there
- Not the highest omega-3 dose on this list
If you’re the type who brings your own bags to the grocery store AND can’t stand fishy aftertaste, this is your pick.
2. Triple Strength Omega 3 Fish Oil (Mystery Brand)
3600 mg per serving with 1300 mg EPA + 860 mg DHA, 120 count
What’s Good:
- Mega-dose of omega-3s (2100+ mg of the good stuff per serving)
- 120 softgels = fewer trips to the supplement store
- Burpless formula (because nobody wants to taste fish twice)
What’s Not:
- No clear info on third-party testing
- Sustainability certifications? We don’t know her.
If you’re the type who doesn’t just want omega-3s, but NEEDS omega-3s in bulk, this is your heavyweight champion.
3. Micro Ingredients Triple Strength Omega 3
4200 mg per serving, 240 softgels, lemon-flavored, 1200 mg EPA + 900 mg DHA
What’s Good:
- Massive bottle (240 softgels = supplement stockpiling)
- High EPA/DHA content (2100 mg combined)
- Lemon flavor masks the fish (like putting perfume on a seal)
- Sourced from deep sea fish (allegedly fewer toxins)
What’s Not:
- Lemon flavor might not be everyone’s jam
- Vague on specific sourcing details
If you’re the type who buys toilet paper by the pallet at Costco, you’ll appreciate this massive bottle of omega-3s.
4. Viva Naturals Omega 3 Fish Oil Supplement
2500 mg triple strength, 30 softgels, high EPA (1400 mg) and DHA (480 mg)
What’s Good:
- Wild-caught small fish (sardines, anchovies, mackerel) = lower mercury
- Molecularly distilled to remove heavy metals and toxins
- Enteric-coated softgels = no fish burps and better absorption
- Third-party tested (they’re not just saying it’s good, they’re proving it)
What’s Not:
- Only 30 softgels per bottle (like buying the small shampoo)
- Premium price point
If you’re the type who reads ingredient labels and won’t put anything sketchy in your body, this premium option is your best bet.
The Bottom Line
- For eco-warriors: Go with Sports Research
- For omega-3 maximalists: Mystery Brand Triple Strength is your jam
- For bulk buyers: Micro Ingredients gives you the most bang for your buck
- For the “I only put quality stuff in my body” crowd: Viva Naturals is worth the premium
Remember, the best fish oil is the one you’ll actually take consistently. Pick one that doesn’t make you gag, fits your budget, and aligns with your values.
And if you hate all fish oil, there’s always flaxseed. But that’s a whole other research brief.
