Proven Benefits

01Reduces rheumatoid pain/stiffness

02Improves skin hydration

03May improve eczema symptoms

04May lower CRP/ESR

Chemical Forms

Recommended

PA-free borage seed oil (20-24% GLA)
PA-free cold-pressed borage seed oil

Avoid

Uncertified borage oil (possible pyrrolizidine alkaloid contamination)
Borage leaf or flower extracts (higher PA contamination risk)

Expert Note

Clinical effects depend on GLA content, so products standardized to roughly 20-24% GLA are more predictable than generic oils. Safety also matters: seed oils certified PA-free are preferred because crude botanical extracts may contain hepatotoxic pyrrolizidine alkaloids.

Protocol

Amount

2-4 g

Frequency

Once daily or split into 2 doses with meals

When

With meals; split the dose if GI upset occurs.

Condition-Based Dosing

Dry or reactive skin

2-3 g daily for 8-12 weeks— Usually provides roughly 400-700 mg GLA depending on the product; stop if no clear benefit. Use PA-free products.

Atopic dermatitis / eczema

2-4 g daily for 8-12 weeks— Evidence is mixed; try a short trial and stop if there is no clear benefit. Use PA-free products only.

Inflammatory joint symptoms

4-6 g daily for 12-24 weeks— Higher intakes are more niche and are better suited to clinician-guided use; choose PA-free products only.

Safety & Limits

Upper Safe Limit

No official UL; long-term studies commonly use up to ~6 g/day of PA-free borage oil (~1.4 g GLA)

Cycling

Safe for continuous use

Contraindications

Pregnancy or trying to conceive — avoid unless a clinician approves; safety data are limited

Breastfeeding — insufficient safety data for routine supplementation

Anticoagulants or antiplatelet drugs — may increase bleeding tendency

Seizure disorders or phenothiazine use — possible lowered seizure threshold

Liver disease — avoid products not explicitly PA-free; contaminated oils can be hepatotoxic

Planned surgery — stop 1-2 weeks before due to possible bleeding risk

Synergies

Omega-3

EPA can compete with arachidonic-acid pathways while borage-derived DGLA supports less-inflammatory lipid mediators, potentially improving the overall eicosanoid balance.
