Swisse Ultiboost 4x review: the highest dose per capsule

Swisse Ultiboost Odourless 4x Strength is the concentrated option here: 720 mg EPA and 486 mg DHA in a single capsule, for around ₱1,300 as of August 19, 2026.

How much stronger is it really?

Genuinely four times, and the numbers are published. Each capsule holds 1,800 mg of concentrated fish oil carrying 720 mg EPA and 486 mg DHA, against roughly 180 mg and 120 mg in a standard 1,000 mg softgel.

That is not a marketing rounding. It is the difference between one capsule a day and three or four, which for most people is the difference between a supplement they keep taking and one that quietly stops.

Does the odourless formulation work?

It substantially cuts the fishy repeat, which is the most common reason people abandon fish oil. It approaches the problem differently from an enteric coating, which physically survives the stomach, but both are aimed at the same complaint.

If you have tried fish oil before and stopped because of the aftertaste, this is one of the two answers in this roundup.

Is a concentrate riskier on contaminants?

It is the right question, because concentrating an oil concentrates whatever else is in it. Swisse states the wild fish oil is tested against international standards for heavy metals including mercury and lead, which is the assurance you want at this strength.

Is it sulit?

At around ₱1,300 as of August 19, 2026, 60 capsules is two months at one a day, so the up-front cost is moderate and the cost per month is higher than the bulk bottles. What you are buying is dose density and palatability, not value per milligram.

It also ships through an overseas store, so delivery takes longer than a locally stocked brand.

Who should buy it

Buy this if you want a high omega-3 dose without swallowing several capsules, or if aftertaste has defeated you before. Skip it if you want the lowest cost per dose, or need it delivered quickly.

Alternatives to consider

For a much lower cost per dose at standard strength, the Webber Naturals 300-count is our Best Overall and publishes its split too. If burps are the specific problem, the LAC Trimax enteric coated attacks it from the other direction.
