Borage Extract: Benefits, Uses, Sources & What You Should Know
Share
Botanical medicine frequently rediscovers ancient remedies through modern clinical science. Among these herbal powerhouses, Borago officinalis—commonly known as the starflower or borage—stands out. Traditionally brewed as an herbal tea in Mediterranean cultures, modern nutritional science now focuses on borage extract, celebrated as nature's richest source of an essential anti-inflammatory fatty acid known as gamma-linolenic acid (GLA).
Borage seed extract is chemically unique because it contains the highest concentration of gamma-linolenic acid (GLA) found in the plant kingdom, typically delivering between 20% and 26% pure GLA by weight.
Where Does It Come From and How Does It Work?
Originating in the Mediterranean basin and now cultivated across Europe and North America, borage thrives in temperate climates. To understand how borage extract works, we must look at essential fatty acid pathways:
Most dietary omega-6 fatty acids come in the form of linoleic acid.
The body must convert linoleic acid into GLA via a rate-limiting enzyme called delta-6-desaturase (D6D).
Stress, aging, high sugar intake, and nutritional deficiencies can impair this D6D enzyme, hindering natural GLA production.
Borage extract bypasses this enzymatic bottleneck completely, delivering pre-formed GLA directly to tissues. Once absorbed, GLA elongates into dihomo-gamma-linolenic acid (DGLA), which competes with pro-inflammatory arachidonic acid to produce Series-1 prostaglandins (PGE1).
Main Evidence-Supported Benefits
Joint Comfort and Mobility
Multiple randomized controlled trials indicate that GLA from borage extract helps modulate joint stiffness and ease morning tenderness.
Skin Barrier Function
Research shows borage extract helps replenish essential epidermal ceramides, reducing transepidermal water loss.
Respiratory and Microvascular Support
Series-1 prostaglandins encourage smooth muscle relaxation, supporting healthy bronchial and microcirculatory tone.
Circadian Rejuvenation Protocols
In Very Naturally Known Men’s Wellness and Very Naturally Known Women’s Wellness, standardized botanical fatty acids work alongside marine collagen peptides and fulvic acid to provide balanced cellular nourishment.
Natural Sources of GLA
Borage Seed Oil (Borago officinalis)
Typical GLA Concentration: 20% to 26%
Black Currant Seed Oil (Ribes nigrum)
Typical GLA Concentration: 15% to 18%
Evening Primrose Oil (Oenothera biennis)
Typical GLA Concentration: 8% to 10%
Hemp Seed Oil (Cannabis sativa)
Typical GLA Concentration: 2% to 4%
Supplements, Safety & Quality Standards
A standardized daily dose of borage extract (205 mg) delivers a concentrated, manageable serving of GLA—often yielding approximately 40 to 50 mg of pure bioactive GLA per capsule.
Wild borage plants naturally synthesize pyrrolizidine alkaloids (PAs), which can be toxic to the liver over time. Always ensure any borage extract you choose is third-party certified as 100% Pyrrolizidine Alkaloid-Free (PA-Free).
Formulations from Very Naturally Known (VNK) are verified under certified EU GMP, NSF, and ISO 22000 quality systems to ensure ingredient purity and verified identity without unnecessary fillers.
What Is the Difference Between Borage Oil and Borage Extract?
Borage oil refers to cold-pressed oil from the seeds, while borage extract often refers to a standardized preparation—liquid or powder—concentrated to guarantee an exact percentage of gamma-linolenic acid, such as 20% or 24% GLA.
Does Borage Extract Contain Omega-3 Fatty Acids?
No. Borage extract is an omega-6 fatty acid source. However, unlike common dietary omega-6s that convert into inflammatory arachidonic acid, the unique structure of GLA pathways produces predominantly anti-inflammatory Series-1 prostaglandins.
Who Should Avoid Taking Borage Extract?
Individuals with active liver disease, those taking pharmaceutical anticoagulants (blood thinners), and pregnant women should avoid borage extract unless explicitly cleared by their physician.
