What is Borage Oil?

Borage oil is extracted from the seeds of Borago officinalis, a flowering herb native to the Mediterranean region and long cultivated across Europe and the Middle East. It contains more GLA — a beneficial omega-6 fatty acid — than any other commonly available plant oil, typically 20–26% GLA by weight, compared to about 8–10% in evening primrose oil. This unusually rich GLA content is what drives most of its therapeutic uses.

How does Borage Oil work?

GLA is converted in the body into a compound called DGLA, which helps produce anti-inflammatory signaling molecules. This puts the brakes on the kind of chronic, low-grade inflammation behind skin flares, joint swelling, and hormonal discomfort. Unlike many omega-6 fats that feed inflammation, GLA tends to work in the opposite direction, supporting a calmer immune and inflammatory response.

What forms does Borage Oil come in?

Capsules are the most practical and consistent form since GLA oxidizes quickly in light and air. Look for products certified as pyrrolizidine alkaloid (PA) free — this label confirms the manufacturer has removed the trace plant alkaloids that can stress the liver with long-term use. Topical borage oil or creams are popular for skin conditions and do not carry the same PA concern since they are not ingested.

Where it comes from:

Borage has been used in European herbal medicine since at least the medieval period, prized as a mood-lifter and tonic — the old saying 'borage for courage' reflected its traditional use for calming nerves. Its seed oil only became a focused supplement after researchers in the 1980s began studying GLA's role in inflammation and skin barrier function.

What does Borage Oil help with?

• Eczema and dry, inflamed skin: GLA is a key building block for the skin's natural moisture barrier. People with eczema often have lower-than-normal GLA levels, and supplementing with borage oil — both orally and topically — helps restore that barrier, reducing redness, itching, and flaking. Results tend to build gradually over 4–8 weeks of consistent use.
• Rheumatoid arthritis: Borage oil's GLA shifts the body's inflammatory signaling in a direction that eases joint swelling and morning stiffness. Clinical studies have shown meaningful reductions in joint tenderness and swelling with daily borage oil use, and some people are able to reduce their reliance on anti-inflammatory medications over time.
• PMS symptoms: GLA helps regulate the hormonal and inflammatory signals that drive PMS discomfort, including mood swings, bloating, and cramps. It is thought to influence prostaglandin balance, the same pathway that many PMS medications target, but through a gentler, nutritional route.
• Cyclic breast pain (mastalgia): Breast pain that follows the menstrual cycle is often linked to an imbalance in fatty acid levels. GLA-rich oils like borage oil have shown genuine benefit for cyclic mastalgia in clinical trials, with many women experiencing significant pain relief after 2–3 months of supplementation.
• Skin aging and barrier repair: As skin ages, its ability to produce and use GLA naturally declines, which contributes to dryness, thinning, and loss of elasticity. Borage oil supplementation and topical application help restore fatty acid levels in the skin, supporting hydration and a more resilient barrier.
• Diabetic nerve pain (neuropathy): GLA has been studied as a nutritional support for nerve health in people with diabetes. It appears to improve blood flow to nerves and reduce the oxidative stress that damages them, which can help ease the burning or tingling sensations of peripheral neuropathy over several months.
• Respiratory inflammation (COPD support): Preliminary human research suggests that GLA-rich oils may help dampen the airway inflammation that drives COPD symptoms, possibly by shifting the body's inflammatory profile toward a less reactive state. This is a developing area and borage oil works best as a supportive add-on, not a standalone treatment.
• Hormonal skin breakouts: Hormonal acne is partly driven by inflammatory processes in the skin's sebaceous glands. GLA can help regulate sebum quality and reduce the inflammatory triggers behind breakouts, particularly the kind tied to hormonal fluctuations in the menstrual cycle.

What can Borage Oil help prevent?

• Skin barrier deterioration in atopic dermatitis-prone individuals
• Progressive joint damage worsening in early rheumatoid arthritis (as adjunct support)

Which foods are rich in Borage Oil?

1. Borage seed oil (supplement): The only commercially meaningful source of GLA at therapeutic levels — 20–26% GLA by weight, far exceeding any common food.
2. Evening primrose oil: The closest dietary cousin — contains 8–10% GLA and is widely available; good alternative or complement to borage oil.
3. Black currant seed oil: Another GLA-rich plant oil at roughly 15–20% GLA, with a similar anti-inflammatory profile.
4. Hemp seed oil: Contains modest GLA (around 2–3%) along with a well-balanced omega-3 to omega-6 ratio that supports the same anti-inflammatory pathway.
5. Spirulina: One of the rare whole foods with measurable GLA content; much lower concentration than borage oil but a useful dietary way to nudge GLA intake upward.

Practical Tips:

GLA is not meaningfully present in everyday foods at therapeutic levels — borage oil, evening primrose oil, and black currant seed oil are the practical sources. To support the same anti-inflammatory pathway through diet, focus on reducing excess omega-6 vegetable oils (corn, soybean, sunflower) that compete with GLA metabolism, and include oily fish or flaxseed to balance the omega-3 to omega-6 ratio.

What are the side effects of Borage Oil?

• Soft stools or loose bowel movements (most common, usually dose-dependent)
• Mild bloating or digestive discomfort
• Nausea when taken on an empty stomach
• Headache (occasional, usually resolves)
• Liver stress if using non-PA-free products long-term
• Increased bleeding time at high doses
• Not recommended during pregnancy: GLA may stimulate uterine contractions

Good to know:

Borage oil is generally safe for most adults when using PA-free certified products at recommended doses. The most important safety step is choosing a reputable brand with a PA-free guarantee, as the alkaloids present in unprocessed borage can be harmful to the liver with long-term use. Avoid during pregnancy.

How much Borage Oil should you take?

• Recommended daily: 1,000–3,000 mg of borage oil daily, providing approximately 240–720 mg of GLA. Rheumatoid arthritis studies have used up to 1,400–2,800 mg GLA/day; skin conditions typically respond to the lower end of the range.
• Best time of day: No strict timing requirement; split doses across two meals for better absorption and reduced digestive discomfort.
• With or without food: Always take with food — fat-soluble GLA absorbs significantly better with a meal containing some dietary fat, and food also reduces the chance of nausea.
• Time to effect: Skin improvements: 4–8 weeks. Joint pain and inflammation: 8–12 weeks. Hormonal/PMS benefits: 2–3 menstrual cycles.
• How long to take it: Safe for continuous use at standard doses when using PA-free products. For joint conditions, clinical studies have used it for up to 18–24 months continuously. Periodic reassessment every 3–6 months is sensible to gauge ongoing need.
