What Is Omega-5?
🔬 Scientific Name: Punicic Acid
Omega-5 is a conjugated linolenic acid (CLnA) found primarily in pomegranate seed oil. It is one of the most potent plant-based antioxidants and is structurally related to conjugated linoleic acid (CLA).
📌 Key Properties:
-
Powerful anti-inflammatory and anti-oxidant
-
Supports skin repair and elasticity
-
Enhances cell regeneration
-
Assists in regulating estrogen-sensitive pathways
-
Offers potential anti-cancer activity
What Is Omega-7?
🔬 Scientific Name: Palmitoleic Acid
Omega-7 is a monounsaturated fatty acid (MUFA) found in sea buckthorn oil, macadamia nuts, and avocado oil. It is naturally present in the skin, eyes, and mucous membranes, making it essential for maintaining cellular hydration and structure.
📌 Key Properties:
-
Promotes metabolic health
-
Supports fat and sugar regulation
-
Enhances skin moisture and glow
-
Improves gut lining integrity
-
Helps combat inflammation and insulin resistance
The Beauty Benefits of Omega-5 & Omega-7
✨ 1. Glowing Skin from Within
Omega-5 protects skin cells from oxidative damage, one of the main causes of premature aging. It helps:
-
Boost collagen synthesis
-
Repair UV damage
-
Reduce fine lines and wrinkles
Meanwhile, Omega-7 hydrates the skin from within, improving:
-
Elasticity and softness
-
Barrier repair for dry or sensitive skin
-
Overall skin tone and clarity
Together, they act like a nutritional facial—repairing and revitalizing your skin at the cellular level.
💇♀️ 2. Hair & Nail Strength
Both fatty acids improve cell membrane integrity, meaning your hair follicles and nail beds stay well-nourished. Results may include:
-
Stronger, shinier hair
-
Reduced hair breakage
-
Improved nail thickness and strength
👄 3. Healthy Mucous Membranes
Omega-7, in particular, is excellent for:
-
Dry eyes
-
Vaginal dryness
-
Nasal passage hydration
Its ability to support mucosal integrity is what makes it so effective in keeping the skin and internal tissues moist and resilient.
Metabolism & Weight Management Support
🔥 1. Fat Metabolism
Omega-7 plays a direct role in:
-
Regulating lipid metabolism
-
Reducing fat accumulation in the liver
-
Promoting healthy insulin response
This means better weight control, especially in those struggling with abdominal fat or insulin resistance.
⚙️ 2. Anti-Inflammatory Metabolic Effects
Omega-5 reduces systemic inflammation—often a root cause of metabolic syndrome. This includes conditions like:
-
Type 2 diabetes
-
Obesity
-
PCOS
-
High cholesterol
When taken regularly, Omega-5 helps to modulate inflammation, promoting better hormonal balance and energy metabolism.
🍽 3. Appetite Regulation & Craving Control
Emerging research suggests Omega-7 may help suppress appetite and reduce cravings by:
-
Influencing leptin and ghrelin (hunger hormones)
-
Stabilizing blood sugar levels
This makes it an ideal companion in weight-loss or intermittent fasting routines.
Scientific Backing
🧪 Studies on Omega-5:
-
A study in Journal of Medicinal Food found that punicic acid has strong anti-inflammatory effects in human skin cells.
-
It also showed promise in blocking the growth of estrogen-responsive breast cancer cells.
🧪 Studies on Omega-7:
-
Research published in Lipids in Health and Disease shows Omega-7 reduces insulin resistance, triglycerides, and C-reactive protein (CRP)—a marker of inflammation.
-
Clinical trials also report improved skin hydration and elasticity after 6–8 weeks of supplementation.
How to Choose a Quality Omega-5 & Omega-7 Supplement
✅ 1. Source Matters
-
Omega-5: Look for cold-pressed pomegranate seed oil

Gelatin (look for plant-based softgels or gummies)
🧴 4. Proper Extraction Methods
-
Supercritical CO₂ extraction or cold-pressed oils preserve the active compounds without degradation.
🏅 5. Certifications
Look for:
-
GMP (Good Manufacturing Practices)
-
FSSAI, ISO, or USDA Organic certifications
