Science-backed benefits of omega-3 fatty acids

Omega-3s are not as desirable; they are life-altering. These are essential oils, which are connected with dozens of health benefits, including the older knowledge and modern science.

1. Omega-3 for brain health and mood stability

The human brain consists of almost 60 percent fat and DHA omega-3 is the foundation compound of the cerebral cortex (the organ of remembering, talking, and creativity). Reduced levels of DHA have been associated with loss of cognitive ability and poor concentration abilities and are likely to cause Alzheimer's (Brown, 2024).

• Case Study: A study published by Healthline highlighted that people with higher DHA intake showed improved memory and reduced symptoms of depression (Rd, 2023).

2. Cardiovascular protection

Two forms of omega-3, EPA and DHA, can lower blood pressure and the amount of triglycerides and reduce the formation of arterial plaque. This minimises chances of cardiac attacks and stroke occurrences (Brazier, 2023).

3. Joint health and inflammation

Omega-3s are powerful anti-inflammatories. They also cause pain relief and decrease pain and stiffness of joints in patients with rheumatoid arthritis and osteoarthritis.

• As stated and expressed by the people who avail of omega-3 supplements, they are capable of feeling more pliable and have less to depend on the prescription pain medicine

4. Eye health

DHA is also found in retinal tissue. Omega-3 deficiencies are linked to dry eyes, macular degeneration, and poor night vision.

5. Pregnancy and child development

Pregnant women supplementing with DHA omega-3 can improve foetal brain and eye development. It’s also known to support mood and reduce postpartum depression risk.

Omega-3 deficiency symptoms

If you're not consuming enough omega-3, your body will start signalling distress. These symptoms are often subtle at first but worsen over time:

• Dry skin or eczema

• Poor concentration or memory lapses

• Chronic fatigue

• Mood swings or depression

• Joint stiffness or unexplained pain

• Brittle nails and hair

• Increased inflammation markers

Quote to remember:
"You may not feel like you are deficient in omega-3 but your body surely does."

You have a high risk of developing it in case you are vegetarian, consume mainly processed food, or do not eat seafood. Fortunately, all people have high-strength and plant-based alternatives.

Not all omega-3 supplements are created equal. Here’s what to keep in mind:

1. Look for high-strength omega-3

Check the label for at least 500 mg of combined EPA + DHA per serving. Lower doses may not provide therapeutic benefits.

Triglyceride forms are better absorbed than ethyl ester versions. Look for supplements that say "re-esterified triglyceride form."
