DHA
DHA is an omega-3 fatty acid that supports brain development, cognitive function, and heart health.
DHA (Docosahexaenoic Acid) is a long-chain omega-3 fatty acid vital for brain development, vision, and cognitive function.
It is especially important during pregnancy and early childhood, but also supports memory and neurological health in adults.
DHA supplements are typically sourced from fish oil or algae and are safe for regular use.

Possible Benefits
Concentrated DHA supports neuronal and retinal health by integrating into cell membranes, providing fluidity and protection against oxidative damage.
- Helps support Cognitive Health by enhancing synaptic plasticity, memory formation, and neuroprotection.
- May promote Eye Health through protective effects on photoreceptor cells and retina structure.
- Contributes to Heart Health by reducing triglycerides, lowering blood pressure, and improving vascular function.
- Often used to support Women's Health during pregnancy, aiding in fetal brain and eye development.
Side Effects
DHA supports brain and eye health, yet mild side effects can occur when starting. Watch for:
- Fishy burps
- Mild indigestion
- Occasional dizziness
- Rare allergic skin reactions
- Subtle shifts in mood or alertness
Interactions
Possible interactions include:
- Anticoagulant therapies: DHA’s blood-thinning effect may add to warfarin or Garlic, monitor INR.
- Lipid-lowering drugs: Supports statin therapy; check lipid panels.
Precautions
DHA on its own may support cognitive and visual function, but keep these safety considerations in mind:
- Fish or algae allergy: Confirm source of DHA; avoid if allergic.
- Anticoagulants: May enhance bleeding; use under medical supervision.
- Pregnant or breastfeeding: Choose pharmaceutical-grade DHA only.
- Gastrointestinal issues: May cause loose stools or burping.
- Before surgery: Stop at least one week prior.
Studies
These studies provide scientific insights into DHA benefits:
A 2013 randomized trial in 50 overweight women with metabolic syndrome showed 2 g/day DHA for 12 weeks improved insulin sensitivity by 15% versus 3% with placebo and reduced hepatic fat content.
A 2012 double-blind RCT in 40 type 2 diabetics found 1 g/day EPA+DHA for 6 weeks lowered CRP by 18% versus 4% with placebo without affecting glycemic control.
No RCTs
have assessed fish-derived DHA for cognitive decline prevention in elderly populations.Disclaimer: This page is for educational purposes and does not replace medical advice. If you're pregnant, have a condition, or take medication, speak with a qualified professional.
