What is GLA (Gamma-Linolenic Acid)? Definition, Health Benefits, and How to Supplement for Wellness

Definition: What is GLA?
GLA (Gamma-Linolenic Acid) is an omega-6 polyunsaturated fatty acid found primarily in certain plant oils, such as borage, evening primrose, and black currant seed oil. It is considered a conditionally essential fatty acid because some individuals may not efficiently convert other omega-6s into GLA due to age, health conditions, or genetics. In supplements, GLA is sought for its potential anti-inflammatory, skin, and hormonal health benefits. Verywell Health and WebMD both recognize GLA as a key ingredient in nutritional wellness.
How Does GLA Work in the Body? (Omega-6 vs. Omega-3 Explained)
GLA is derived from linoleic acid (the main omega-6 in vegetable oils) and, via the enzyme delta-6-desaturase, is converted into DGLA (dihomo-gamma-linolenic acid). This process is crucial because DGLA serves as a precursor to anti-inflammatory compounds (prostaglandins), helping to regulate inflammation, support skin barrier function, and balance hormones.
GLA and Fatty Acid Families at a Glance:
| Aspect | Omega-6: GLA | Omega-3: EPA/DHA |
|---|---|---|
| Main Sources | Borage, primrose, black currant oils | Fish oil, flaxseed |
| Conversion | Converts to DGLA (anti-inflammatory) | EPA/DHA reduce systemic inflammation |
| Core Benefits | Skin health, hormone support, localized inflammation | Heart, brain, whole-body inflammation |
| Typical Diet Balance | Excess omega-6 can promote inflammation if not balanced with omega-3 | Omega-3 balances omega-6 effects |
Maintaining the right omega-6/omega-3 ratio is key; GLA’s unique metabolic pathway allows it to counteract some of the negative effects of excessive dietary omega-6 (like arachidonic acid).
Science-Backed Health Benefits of GLA
Current clinical and scientific reviews indicate:
- Skin Health: GLA may improve skin hydration, barrier function, and is used to help with eczema and overall dryness.
- Anti-Inflammatory Action: Supports the body’s production of anti-inflammatory molecules and may help with conditions like arthritis or inflammatory discomfort.
- Hormonal Balance: Common in supplements for premenstrual syndrome (PMS), menopausal discomfort, and general women’s health.
- Potential Cardiovascular Support: Ongoing research is exploring benefits for heart health and neuropathy.

Focus: The scientific application of natural active ingredients such as Tongo Ali, Horny Goat Weed, and Maca to sexual health and metabolic regulation.
Core Focus:
Men: Use a combination of Tongo Ali (an energizing factor) + Maca (an energy reserve) to improve low energy and fluctuating libido.

Product Concept:
Based on traditional applications and modern research (e.g., Tongo Ali promotes testosterone-enhancing enzyme activity, and icariin provides gentle regulation), we preserve core active ingredients and eschew conceptual packaging—using natural ingredients to address specific needs.
Simply put: I'm a nutritionist who understands "herbal actives." I use scientifically proven ingredients like Tongo Ali, Epimedium, and Maca to help you make "sexual health" and "nutritional support" a daily routine.
