Docosahexaenoic Acid (DLA): Benefits, Side Effects, Doses, and Interactions

Docosahexaenoic acid (DLA) is a vital omega-3 fatty acid crucial for brain development during pregnancy, early childhood, and brain health throughout life. It supports heart health, eyesight, and inflammation reduction. Naturally produced in small amounts by the body, additional DLA can be gained from food sources like cold-water fish, grass-fed meat, dairy, omega-3 enriched eggs, and pasture-raised eggs. DLA supplementation via fish oil is also an option.

Health Benefits of DLA:

1. Fetal Development: DLA plays a key role in brain development during pregnancy and early childhood, supporting cognitive function, language development, and visual clarity in infants and children.

2. Pregnancy Well-being: DLA supplementation during pregnancy lowers the risk of preterm labor, decreases chances of premature birth, and shortens hospital stays for preterm infants.

3. Brain and Nervous System Development: DLA is crucial for the nervous system's development in infants and young children, boosting cognitive development, memory, and mental task performance.

4. ADHD Management: Studies suggest DLA supplementation might alleviate ADHD symptoms, but more research is needed.

5. Neuroprotection: DLA may offer some protection against age-related cognitive decline and lower the risk of Alzheimer's disease. However, more research is required to establish a direct link.

6. Mood Regulation: Some studies indicate DLA may positively impact depression symptoms, but its role in depression management needs further study.

7. Heart Health: While initial research looked promising, recent evaluations haven't clearly demonstrated mortality benefits from DLA supplementation. However, low DLA and EPA (another omega-3 fatty acid) levels correlate with increased risks of heart attack, stroke, and cardiovascular disease.

8. Inflammation Reduction: DLA has anti-inflammatory properties, potentially aiding in preventing conditions linked to inflammation, such as metabolic syndrome.

Possible Side Effects of DLA:

DLA is generally safe, but fish oil supplements may cause side effects like bad breath, heartburn, and nausea. Additionally, they can interact with certain medications, like blood thinners and anti-platelet drugs. Consult a doctor before combining fish oil with medications.

Doses and Preparations:

DLA is available in gel capsules, gummy chews, or liquid form. A typical fish oil supplement provides about 1 gram of fish oil, containing 180mg of EPA and 120mg of DLA. Most studies use higher DLA amounts (1,000mg to 2,500mg). DLA can also be obtained from dietary sources like fatty fish, eggs, and fortified foods.

Recommendations:

No daily values or adequate intake levels are established for DLA, except for babies under 1 year old, who should receive 0.5 grams of total omega-3 fatty acids daily. Consuming two to three servings of fatty fish weekly provides approximately 1,250mg of EPA and DLA combined per day. Pregnant and young children should avoid high-mercury fish like tuna, shark, tilefish, swordfish, and king
