If you’ve ever stood in the supplement aisle staring at a wall of fish oil bottles, you’re not alone. It’s one of the most talked-about supplements in New Zealand, but is it actually worth taking?
Here is a straightforward look at what fish oil does, who benefits most, and how to tell if a supplement is delivering what it promises on the label.
What is Fish Oil (and Why Can’t Your Body Make It?)
Fish oil is exactly what it sounds like: oil extracted from fatty fish like salmon, sardines, and mackerel. It is uniquely rich in Omega-3 fatty acids, specifically EPA and DHA.
These are the nutrients your body actually uses. Unlike some nutrients, your body cannot create EPA and DHA on its own; you must obtain them through your diet or a high-quality supplement.
The Different Roles of EPA and DHA
It is important to understand that EPA and DHA perform different, vital functions as we age:
- EPA: This fatty acid is involved in supporting your heart and your body’s natural inflammatory response. These are foundational systems that become increasingly important for maintaining mobility and cardiovascular health.
- DHA: This is a primary structural building block of the brain and eyes. It supports a healthy mind, mental clarity, and vision over time.
The "Oily Fish" Reality Check
Health recommendations suggest eating oily fish two to three times per week. However, for many New Zealanders, that simply doesn't happen due to busy schedules, the rising cost of fresh fish, or personal taste.
If fish isn't a staple in your diet today, your body is depending on those nutrients, now more than ever. That is why we created Lester’s Oil. Not as a "trend," but as a reliable way to keep your EPA and DHA intake simple and consistent
Why Lester’s Oil Stands Apart
Not all fish oils are the same. Omega-3 supplements can vary wildly in quality, and unfortunately, the amount of EPA and DHA listed on the label isn’t always what you’re actually getting.
When you are taking a supplement every day, the cost adds up. You want to know you are paying for the actual nutrients, not just the "idea" of them. Lester’s Oil is built on proof, not promises:
- Independent Batch Testing: Every single batch is independently tested to confirm the EPA and DHA levels match or exceed label claims.
- Purity Standards: We verify that the oil is free from unwanted contaminants and heavy metals.
- Backed by a human study: Lester’s Oil is backed by a human study which showed an increase in omega-3 levels by 59% in 4-weeks, proving the quality and efficacy of this high quality supplement.
For those looking for a higher concentration per serve, Lester’s Oil Advanced offers a more concentrated option, providing more EPA and DHA for advanced support.

The "Power Couple": Fish Oil and Resveratrol
While fish oil covers your foundational Omega-3 intake, long-term wellbeing rarely comes down to a single nutrient. This is why many people pair their fish oil with Resveratrol (found in Res-V Plus).
- Omega-3s: Provide the essential structural support for the heart, brain, and joints.
- Resveratrol: A naturally occurring antioxidant studied for its role in supporting cardiovascular health and cellular wellbeing.
Adding Res-V Plus alongside fish oil isn’t about "doubling up". It’s about covering different aspects of health. While Omega-3s support function, antioxidants support the body’s natural defense systems at a cellular level, energy levels and immune health. Therefore, the two combined is a considered, long-term approach to staying well as you age.
