1. Provides cardiovascular support: Quell Fish Oil contains high levels of EPA and DHA, two essential omega-3 fatty acids that have been shown to support heart health and reduce the risk of cardiovascular diseases.
2. Boosts brain function: The high levels of EPA and DHA found in Quell Fish Oil have been linked to improved brain function and cognitive health, making it an ideal supplement for those looking to enhance their memory and focus.

The Active Ingredient Is: Omega-3 fatty acids (EPA and DHA) from fish oil

Omega-3 fatty acids, including EPA and DHA, are polyunsaturated fats found naturally in fish oils and play a key role in everyday bodily function. This formulation uses marine omega-3 triglyceride concentrates as the main active ingredient.

The source is marine fish oil, chosen for its triglyceride form delivery, which supports better bioavailability than other forms. The product also includes vitamin D3 to address common deficiency concerns and complement omega-3 intake.

What Do Omega-3s Do?

Omega-3 fatty acids help support normal heart function and cognitive health, with EPA linked to inflammatory response regulation and DHA to brain function, as recognised by EFSA. Vitamin D3 supports immune function as part of a balanced intake.

These nutrients work together to support overall wellness by providing essential fatty acids for normal bodily processes and nutrient interactions in the body.
