1. Check the Type of Omega-3

• EPA & DHA → found in fish and algae oil; most effective for heart, brain, mood, joints.
  
  

• ALA → from plant oils (chia, flax, walnuts); useful, but converts poorly into EPA/DHA.
  👉 Women 40+ should prioritize EPA + DHA for cardiovascular and cognitive health.
  
  

2. Look at the Dose (Per Serving, Not Per Bottle)

• General wellness: 500–1,000 mg EPA+DHA daily.
  
  

• For specific support (high triglycerides, joint stiffness): 2–3 g/day (doctor-supervised).
  👉 Always check “per serving EPA+DHA”, not just “fish oil amount.”
  
  

3. Absorption Form Matters

• Triglyceride (TG) or Phospholipid → better absorbed.
  
  

• Ethyl Ester (EE) → cheaper, less bioavailable unless taken with fat.
  👉 If digestion or absorption is an issue, look for TG, phospholipid, or emulsified liquid formulas.
  
  

4. Purity, Safety & Testing

• Fish can contain mercury, PCBs, dioxins.
  
  

• Choose brands with third-party testing (IFOS, USP, or NSF).
  
  

• Freshness counts: rancid fish oil loses potency and may harm health.
  👉 Look for “molecularly distilled” or “third-party tested for purity.”
  
  

5. Side Effects & Safety

• Common: mild fishy burps, GI upset.
  
  

• High doses: may increase bleeding risk, especially with blood thinners.
  
  

• Safe upper limit (supplements): ≤3 g EPA+DHA daily (FDA).
  👉 Always check with your doctor if you take anticoagulants or hormone therapy.
  
  

6. Added Ingredients Can Be a Bonus

• Astaxanthin → antioxidant (great for skin, eyes, heart).
  
  

• Vitamin D or E → supports bones, immunity, and oxidative protection.
  
  

• Choline → brain metabolism, memory support.
  👉 Consider blends if you want extra skin, brain, or immune benefits.
  
  

7. Choose Based on Your Lifestyle & Goals

• Heart health / cholesterol → higher EPA (e.g., Viva Naturals).
  
  

• Brain fog & memory → higher DHA (e.g., Carlson, Sports Research Vegan).
  
  

• Joints & inflammation → EPA-rich or krill oil (e.g., MegaRed, Micro Ingredients Triple Strength).
  
  

• Skin & hair beauty → Black Seed Oil, or fish oils with added antioxidants.
  
  

• Vegan preference → Algae oil (e.g., Sports Research Vegan Omega-3).
  
  

8. Cost vs. Value

• Don’t just pick the cheapest bottle—calculate cost per 1,000 mg EPA+DHA.
  
  

• Some budget products require 6+ capsules daily to hit target dose, making them less convenient and not really cheaper.
  👉 The right product balances potency, purity, and price.
  
  

✨ Bottom Line for Women 40+:

Choose an omega-3 with at least 500–1,000 mg EPA+DHA daily, in a well-absorbed form, from a brand that provides purity testing. Match the formula to your main goal (heart, brain, joints, or skin) and always stay within safe dosage.

Hormonal changes after 40 can affect heart, brain, mood, joints, skin, and overall vitality. Choosing the right supplement helps target these needs.
