OmegaXL is a fish oil product which makes some aggressive health claims: the brand claims their product is 20x more potent than standard fish oil. We know from medical research that fish oil, and specifically the omega-3 fatty acids it contains, are beneficial for human health. But OmegaXL’s claim seems to be questionable at face value.
In this article, we’ll analyze the formulation of OmegaXL to determine if it’s likely to be effective, and also analyze if their claim of increased potency holds up to medical research.
We'll also overview some third-party test results suggesting the product may not be very effective at all.
OmegaXL Ingredient Review
OmegaXL doesn’t publish a Supplement Facts label on their website. Not only is this arguably in violation of FDA labeling requirements, but it’s a clear red flag that a company doesn't respect their consumers.
Why would a dietary supplements company not tell their consumers what’s in the product they’re selling, and at what dosage, if not to be deceptive?
Thankfully we can get the Supplement Facts label (shown above) from Amazon because Amazon has stringent listing requirements.
OmegaXL contains a proprietary (prop) blend with a total dosage of 300 mg. Prop blends are another red flag for consumers about the ethics of a company. Instead of just listing the exact dosage of every ingredient, companies will just list the dosage of the entire blend, which can prevent consumers and researchers from determining if the product is likely to be effective.
A 300 mg dosage for this product seems very low, given that we know from existing research on fish oil that usually doses over 1 gram (g) is used in medical research. If the entire dosage in OmegaXL is less than 33% of what appears to be the effective dose of fish oil, it’s a bad sign since fish oil is just one of three ingredients in the prop blend, meaning the actual dose of fish oil is necessarily less than 300 mg.
Questionable Medical Studies Backing OmegaXL
OmegaXL uses a patented fish oil extract called “PCSO-524”. One medical study on this patented oil did find it to be more effective than fish oil for treating arthritis pain, but we believe the study was designed poorly.
The study was funded by the company which makes the patented fish oil, and the regular fish oil used for comparison seems extremely underdosed at 150 mg/day. Since most medical research on regular fish oil for pain uses dosages well over 1 g/day, it appears to us that the private company funding the trial intentionally set it up to fail so their patented oil looked superior.
Another study on the patented fish oil in OmegaXL was also funded by the same holding company Pharmalink International Ltd., also also appears intentionally poorly designed.
The second study tested PCSO-524 supplementation on inflammation in muscle post-exercise, and found it to be a useful therapeutic agent, but the patented fish oil was compared to olive oil instead of regular fish oil! This provides zero useful insight. Also, the dosage used was 1200 mg/day, or 4 times the amount in the entire OmegaXL capsule (which contains other ingredients too).
Overall we believe the research backing this product is so poorly designed as to be essentially worthless. PCSO-524 may be more effective than placebo, but we don’t believe the medical trials, which had significant bias, proved it was more effective than regular fish oil supplementation at an effective dose.
Unproven Health Claims
OmegaXL’s core claim is that their product is 20x more potent than standard fish oil. This is a strange claim to make with literally zero published proof on their website. Just saying something doesn't make it true.
We don’t even know how the company is assessing “potency” of a fish oil: is it in terms of EPA/DHA which are the active fatty acid compounds in fish oil? Because if so there is zero proof this product contains such a high potency relative to standard fish oil.
We have no idea what they’re referencing with this health claim, and the company provides no backing for it, so we can assume it’s entirely made up for marketing and inaccurate.
We can conclude by how underdosed OmegaXL is that it's necessarily ineffective.
Bad Third-Party Testing Results
ConsumerLab is an independent laboratory which publishes test results of supplements. They tested OmegaXL and found very few omega fatty acids at all, and concluded that the product had a “chemical profile similar to olive oil”.
This is another red flag and bad sign for OmegaXL, because ConsumerLab, unlike studies funded by the company which owns the patented fish oil contained in OmegaXL, has no apparent biases or reason to misreport testing. They’re the most accurate third-party publisher in our opinion.
It appears from their test results that OmegaXL isn't primarily made of fish oil at all, but is cut with cheaper oils so the company can make higher profits.
