Black currant seed oil provides GLA plus some omega-3 ALA, feeding the same anti-inflammatory eicosanoid pathway as evening primrose and borage oil, but it's the least-validated of the three GLA oils in humans, with essentially no strong standalone outcome trials.
Form: Ribes nigrum seed oil (contains GLA ~15-20% plus some ALA)
Typical dose studied: 1.5-3 g/day; no validated dose
Timing: With food
Ships trigger-empty -- included for completeness of the GLA-oil family (alongside evening primrose and borage), not because the standalone evidence supports an active recommendation.
? Emerging / limited evidence
Avoid with: Breastfeeding; Epilepsy / Seizure disorder; Bleeding disorder / Coagulopathy
Interacts with: Anticoagulants, antiplatelets -- theoretical additive bleeding risk
Already taking it? Least-studied of the GLA oils -- reasonable to continue if well tolerated, but don't expect trial-backed benefit for skin, joint, or hormonal claims.
