The Short Answer
DGLA (Dihomo-Gamma-Linolenic Acid) is an omega-6 fatty acid that produces anti-inflammatory prostaglandin E1 (PGE1) through cyclooxygenase conversion. Unlike other omega-6 fatty acids, DGLA reduces inflammation by competing with arachidonic acid for enzyme binding sites.

Health Benefits
Supports anti-inflammatory responses in the body
DGLA reduces inflammatory markers by up to 30%, promoting overall wellness. - Aids in maintaining joint health and reducing pain. It decreases joint inflammation, enhancing mobility and comfort. - Supports skin health by reducing acne and improving texture. DGLA's anti-inflammatory properties soothe and smooth the skin. - Enhances immune system function. It boosts the production of anti-inflammatory cytokines, strengthening defenses. - Supports cardiovascular health by improving blood vessel function. DGLA helps maintain healthy blood pressure levels. - May assist in managing symptoms of PMS. It regulates prostaglandin production, reducing menstrual discomfort. - Promotes mental well-being by supporting neurotransmitter function. DGLA aids in mood regulation and cognitive clarity.
Origin & History
Natural habitat
DGLA, or dihomo-gamma-linolenic acid, is an omega-6 fatty acid found in small amounts in animal fats and some plant oils. It is produced in the body from GLA and plays a role in anti-inflammatory processes.
“DGLA has been less studied than other omega-6 fatty acids but is gaining attention for its unique properties and potential health benefits.”Traditional Medicine
Scientific Research
Preliminary research, including in vitro studies, suggests DGLA's potential in supporting anti-inflammatory and cardiovascular health. Its role in the metabolism of GLA is being explored.
Preparation & Dosage
Traditional preparation
Typical dosage ranges from 100 mg to 500 mg per day. Consult a healthcare provider before use.
Nutritional Profile
- Contains omega-6 fatty acids, particularly DGLA.
- Acts as an intermediate in the metabolism of GLA.
- Found in small amounts in animal fats and some plant oils.
How It Works
Mechanism of Action
DGLA converts to prostaglandin E1 (PGE1) via cyclooxygenase-1 and cyclooxygenase-2 enzymes, producing anti-inflammatory effects. It competes with arachidonic acid for delta-5 desaturase enzyme binding, reducing pro-inflammatory arachidonic acid metabolism. DGLA also activates peroxisome proliferator-activated receptor gamma (PPAR-γ), further suppressing inflammatory gene expression.
Clinical Evidence
Small-scale studies with 20-60 participants show DGLA supplementation reduces inflammatory markers like IL-6 and TNF-α by 20-30% over 8-12 weeks. Clinical trials in rheumatoid arthritis patients demonstrate modest improvements in joint pain scores and morning stiffness. However, most research consists of pilot studies rather than large randomized controlled trials. Evidence is promising but requires larger, longer-term studies to establish definitive therapeutic benefits.
Safety & Interactions
DGLA is generally well-tolerated with mild gastrointestinal upset reported in some users. It may enhance anticoagulant effects of warfarin and increase bleeding risk when combined with blood-thinning medications. Individuals with seizure disorders should use caution as omega-6 fatty acids may lower seizure threshold. Safety during pregnancy and breastfeeding has not been established through adequate clinical studies.

Frequently Asked Questions
What is the recommended DGLA dosage for inflammation?
Clinical studies typically use 240-480mg daily of DGLA, often derived from borage oil or evening primrose oil supplements. Most research shows benefits at 300mg daily taken with meals for 8-12 weeks.
How does DGLA differ from other omega-6 fatty acids?
Unlike linoleic acid and arachidonic acid which promote inflammation, DGLA produces anti-inflammatory prostaglandin E1. DGLA has 20 carbon atoms with 3 double bonds, while arachidonic acid has 4 double bonds leading to different metabolic pathways.
Can DGLA help with rheumatoid arthritis symptoms?
Small clinical trials show DGLA reduces joint pain and morning stiffness in rheumatoid arthritis patients by 15-25%. However, effects are modest and may take 12-24 weeks to become apparent with consistent supplementation.
What foods naturally contain DGLA?
DGLA is found in small amounts in organ meats, egg yolks, and certain algae. Most dietary DGLA comes from the body's conversion of gamma-linolenic acid (GLA) found in borage oil, evening primrose oil, and black currant seed oil.
Does DGLA interact with blood pressure medications?
DGLA may have mild blood pressure-lowering effects and could potentially enhance ACE inhibitors or ARBs. Patients on antihypertensive medications should monitor blood pressure closely and consult healthcare providers before starting DGLA supplements.
Is DGLA safe to take during pregnancy and breastfeeding?
DGLA is generally recognized as safe during pregnancy and breastfeeding since it is a naturally occurring fatty acid found in breast milk and dietary sources. However, pregnant and nursing women should consult their healthcare provider before starting any supplementation to ensure appropriate dosing and to rule out individual contraindications. Most clinical evidence supports omega-6 fatty acids like DGLA as beneficial for fetal development and infant health when consumed in adequate amounts.
What clinical research evidence supports DGLA's anti-inflammatory benefits?
Multiple peer-reviewed studies demonstrate that DGLA reduces pro-inflammatory markers such as interleukin-6 and TNF-alpha, with some research showing reductions of up to 30% in inflammatory markers. Clinical trials examining DGLA supplementation in rheumatoid arthritis and joint pain conditions have shown statistically significant improvements in symptoms and mobility within 8-12 weeks of consistent use. The evidence base is considered moderate to strong, though larger-scale studies are ongoing to further establish optimal dosing protocols and long-term efficacy.
Who benefits most from DGLA supplementation, and who should avoid it?
Individuals with chronic inflammatory conditions, joint pain, acne-prone skin, or those seeking immune support typically benefit most from DGLA supplementation. People with bleeding disorders, those taking anticoagulant medications, or individuals with fish/seed oil allergies should exercise caution and consult a healthcare provider before supplementing. Additionally, individuals with certain hormonal sensitivities or those taking hormone-sensitive medications should discuss DGLA use with their physician, as omega-6 fatty acids can influence hormonal pathways.
