Ultimate Omega Xtra Lemon combines omega-3s and vitamin D, with good value for the EPA and DHA supplied. The oil’s precise structure is unclear, so its absorption cannot be compared confidently.

AI assessment of the formula, label and price. How scoring works

Nutrient Quality26

EPA and DHA are identified, but those names do not establish the oil’s precise structure. Its absorption potential therefore remains uncertain.

Ingredient Transparency82

Ingredient amounts and the omega-3 components are disclosed, making the fatty-acid breakdown easier to check. Some ingredient forms remain unclear.

Value For Money64

The omega-3s offer good value for the amount of EPA and DHA supplied. The vitamin D contribution has less certain value.

Customer Satisfaction85

Customer feedback is favorable across a substantial number of ratings. Those opinions describe satisfaction, rather than proving health benefits or safety.

Product Focus75

The formula has useful support across a small set of intended goals. Its main purpose remains omega-3 supplementation with added vitamin D.
