Docosahexaenoic Acid - omega-3 fatty acid critical for brain and eye development
We rank DHA by price per gram of active ingredient - not by pack size - so a bigger tub with a worse price per dose can't outrank a smaller one that's actually cheaper.
What it is
DHA, or Docosahexaenoic Acid, is a type of omega-3 fatty acid. These are essential fats, meaning they are nutrients the body cannot make on its own and must be obtained through food or supplements.
Why it's used
It is primarily used because it is critical for the development and function of the brain and the eyes. It helps maintain the structure of cells in these organs to support cognitive health and vision.
How it's made
To create the supplement, manufacturers extract oil from fatty fish or algae. This oil is then refined and concentrated to increase the amount of DHA while removing unwanted impurities, before being put into softgel capsules or liquid bottles.
What it typically costs
This ingredient is generally mid-range in price. This is because the process of refining and concentrating the oil to ensure high purity and potency is more complex than producing basic, unrefined fish oils.
