Are you struggling with skin issues, heart health, or a restless mind? Instead of countless treatments, consider the powerful force of Gamma-Linolenic Acid (GLA). This omega-6 fatty acid goes beyond contemporary science, drawing from ancient remedies and offering remarkable benefits.
What is Gamma-Linolenic Acid (GLA)?
Gamma-linolenic acid (GLA) is an omega-6 fatty acid found in various plant-based oils such as evening primrose (EPO), borage oil, and black currant seed oil1. GLA, along with omega-3 fatty acids, plays a crucial role in brain function, normal growth and development, skin and hair growth, bone health, metabolism regulation, and maintaining the reproductive system.
The body converts linoleic acid (LA) to GLA and then to arachidonic acid (AA)2. Gamma-linolenic acid can also be obtained directly from plant-based oils.
A healthy diet should contain a balance of omega-3 and omega-6 fatty acids. However, the typical American diet contains significantly more omega-6 fatty acids than omega-3 fatty acids, which may contribute to the high prevalence of inflammatory diseases in the American population.
Gamma-Linolenic Acid (GLA) is an essential omega-6 fatty acid found in plant oils such as borage, evening primrose, and black currant seed, known for its anti-inflammatory properties and benefits in brain function and skin health.

Food Sources
Gamma-linolenic acid (GLA) is a key omega-6 fatty acid essential for many bodily functions. Since our body can’t produce GLA independently, it’s vital to know where to find it in our diet.
- Borage Oil (18-26% GLA): From starflower seeds, borage oil is packed with Gamma-Linolenic Acid, boasting about 24% of its content.
- Spirulina: This blue-green algae, among the world’s most nutritious foods, is rich in GLA, making up to 40% of its total fatty acids.
- Evening Primrose Oil (7-10%): A medicinal oil from primrose seeds, it’s a long-standing source of GLA.
- Black Currant Seed Oil (15-20%): Extracted from black currant seeds, this oil is another GLA provider.
- Hemp Seed Oil (3%): Hemp oil offers GLA and other valuable fatty acids in various amounts.
These natural food sources offer a straightforward way to ensure our intake remains consistent, promoting overall balance in our body’s functions.
Understanding GLA’s Role in Our Body
Gamma-linolenic acid, or GLA for short, is a special fat that plays a big role in how our body deals with swelling and pain. Let’s take a closer look at what GLA does and why it’s important.
Aspect of GLA | Details |
---|---|
Anti-inflammatory properties | GLA helps reduce swelling, redness, and pain in the body. |
Mechanism: Transformation of linoleic acid | Linoleic acid, an essential fatty acid, is converted into GLA. This GLA then turns into compounds like DGLA and PGE1, which are vital for health. PGE1 is particularly known for its anti-inflammatory properties. |
Modulation of inflammation | GLA modulates inflammation, ensuring it doesn’t become chronic or excessive. It’s not about eliminating inflammation but about keeping it in check. |
Implications for autoimmune conditions | GLA can help manage autoimmune conditions like rheumatoid arthritis by reducing pain and swelling. |
Bioactive Metabolites | As the body processes GLA, it produces compounds like PGE1. These compounds have their own health benefits. |
Dietary Importance | The conversion of linoleic acid to GLA can be inefficient due to factors like aging and stress. This underlines the need for direct GLA dietary sources. |
Potential Side Effects | Excessive GLA might cause complications. It’s essential to understand the right amounts to consume. |
While Gamma-Linolenic Acid offers numerous health benefits, understanding its sources, mechanisms, and potential interactions is crucial.
Health Benefits of GLA
The ancient moniker of Gamma-Linolenic Acid as the “king’s cure-all” stems from its use in homeopathic remedies and folk cures3. Historically, it’s been championed for a plethora of conditions:
![Health benefits of gamma-linolenic acid](https://cannabishempcare.com/wp-content/uploads/2023/10/Health-Benefits-of-GLA.jpg)
- Skin Conditions: Eczema and acne sufferers have reported relief from GLA, potentially due to its anti-inflammatory properties.
- Diabetic Complications: Nerve problems due to diabetes, termed diabetic neuropathy, and Diabetic nephropathy, a kidney condition, might benefit from GLA supplementation. However, while some studies suggest potential benefits, more rigorous research is imperative.
- Cardiovascular Health: High blood pressure (hypertension) might see modulation under GLA.
- Reproductive Health: From alleviating mastalgia (breast pain) and menopausal symptoms to providing relief of PMS symptoms, GLA shows diverse applications.
- Bone Health: Preliminary research indicates a potential role of GLA in combating osteoporosis.
- Mental Health: Some early evidence links GLA to relief in Attention-deficit/hyperactivity disorder (ADHD) symptoms.
- Cancer Therapy: The potential of GLA in breast cancer treatment is under exploration, specifically regarding its ability to increase lymphocytes, essential cells in the immune response.
Dosage Recommendations
Studies have often employed a Gamma-Linolenic Acid dosage range of 0.5 to 3 g per day4.
While there’s no standard GLA dosage due to the lack of official endorsement for specific ailments, various studies, and user experiences have led to certain commonly suggested dosages:
Condition/Usage | Recommended GLA Dose (mg/day) |
---|---|
Weight Management | 890 mg |
Diabetic Neuropathy | 360-480 mg |
Immune & Inflammation Disorders | 1,400-2,800 mg |
Dry Eye Conditions | 30-50 mg |
Eczema (Adults) | 160-480 mg |
Eczema (Children) | 80-320 mg |
Cardiovascular Health | 240-560 mg |
However, the exact amount can vary based on individual conditions and should always be determined in consultation with a healthcare professional. Specific populations, such as pregnant women, are advised against using Gamma-Linolenic Acid unless under strict medical guidance.
Interactions
Like all bioactive compounds, Gamma-Linolenic Acid isn’t without its cautions. Some potential side effects, although usually mild, encompass acid reflux, diarrhea, itchiness, nausea, problems with concentration, stomach pain, and fatigue.
Notably, at dosages of 2.8 grams per day, Gamma-Linolenic Acid is possibly safe for most adults but might cause some digestive tract side effects.
Caution is advised when GLA is taken concomitantly with certain medications:
