DHA (docosahexaenoic acid) is a polyunsaturated omega-3 fatty acid. It is a natural building block of cell membranes and is found in particularly high concentrations in the brain and in the retina of the eye.
What is DHA?
DHA belongs to the group of omega-3 fatty acids, together with EPA (eicosapentaenoic acid) and ALA (alpha-linolenic acid).
- Origin in the body: The human body can only produce DHA itself from ALA or EPA to a very limited extent.
- Intake via diet: DHA must therefore be obtained predominantly via food or dietary supplements.
- Natural sources: Cold-water fish (e.g., mackerel, tuna, cod) and other marine animals such as krill contain DHA. Plant-based sources are certain microalgae from which vegan DHA oil is obtained.
- Function in the body: DHA is a component of cell membranes, especially in the brain and retina, and is involved in the structural and functional processes of these cells.
Why do people take DHA as a dietary supplement?
People who eat little or no fish (e.g., those on a vegan or vegetarian diet, or those who consume little fish) often do not achieve the recommended intake of DHA through their diet. In this case, a dietary supplement can help to supplement the intake.
Typical reasons for DHA supplementation:
- low or no regular consumption of fish
- vegan or vegetarian diet
- targeted supplementation of the daily omega-3 intake
Forms of DHA supplements
Source | Description |
|---|---|
Fish oil | Classic source of DHA and EPA, obtained from cold-water fish |
Algae oil (vegan) | Plant-based source of DHA from microalgae, without animal ingredients |
Krill oil | DHA and EPA from krill, often bound in phospholipid form |
What to look for when buying DHA capsules
- Origin: fish oil, krill oil or vegan algae oil
- DHA content per capsule/daily dose: specified in milligrams on the packaging
- Combination with EPA: Many products contain both DHA and EPA
- Purity: tests for heavy metals and pollutants (e.g., by independent laboratories)
- Additives: composition without unwanted additives, if desired
- Certifications: e.g., organic or vegan seal, depending on the product
Other names of DHA:
Docosahexaenoic Acid, ADH, Omega 3 Fatty Acids, Omega-3 Fatty Acids, W-3 Fatty Acid
Frequently Asked Questions About DHA Supplements
Yes. Vegan DHA is obtained from microalgae and contains no animal ingredients.
DHA and EPA are both omega-3 fatty acids that play different structural roles in the body. Many supplements contain both in combination.
Soft capsules (fish oil, krill oil) or vegan capsules based on algae oil are common.
No. Omega-3 is the umbrella term for a group of fatty acids that includes DHA, EPA and ALA.
DHA is therefore one of several omega-3 fatty acids, not another name for the whole group.
A DHA deficiency means that less DHA is absorbed through diet or nutritional supplements than the body usually needs.
Since the body can only produce DHA itself to a limited extent, this mainly affects people who consume little fish, for example those on a vegan or vegetarian diet.
The most DHA is found in high-fat cold-water fish such as salmon, mackerel, herring and tuna, as well as in krill.
DHA is found in certain microalgae in plant form – this is also the source of vegan DHA in capsule form.
Both perform different functions in the body and are considered equally relevant – DHA is more concentrated in the brain and retina, while EPA performs other tasks in the metabolism. So it's less about which one is "more important", but rather about the fact that both together make up the typical omega-3 intake.
There is no single officially defined ratio – products on the market vary greatly, from EPA-heavy to DHA-heavy. The right ratio depends on your personal goal and, if necessary, consultation with a nutritionist.
The EFSA (European Food Safety Authority) gives a standard intake recommendation for adults of about 250 mg of EPA + DHA combined per day. Different recommendations apply for certain stages of life (e.g., pregnancy).
The EFSA considers food supplements with up to 5 g of EPA and DHA combined per day to be harmless. In the case of very high amounts or blood thinners, a doctor should be consulted in advance.
DHA capsules are usually taken with a meal, as their fat solubility promotes absorption in the body. There is no requirement to take them at a fixed time of day – what is most important is regularity.
