Frequently Asked Questions

How much Omega-3s will I be getting?

Two softgels will give you 2000mg of omega-3 (that's 660mg EPA & 440mg DHA), more than an entire tin of sardines.

When is the best time to take fish oil?

We suggest taking the product at meal times - ideally at dinner as this helps your body absorb and digest it. Plus taking it at a consistent time makes it easy to add into your daily routine for consistency.

Can I take this with other products?

Yes. This product works well in combination with other products from our range and Omega-3s are extremely well-tolerated by almost everyone. If you have any concerns, please speak to your GP.

Does this have a fishy aftertaste?

No. Our formula is premium quality, molecularly-distilled & super fresh with far less oxidation than other supplements. You should never experience a bad taste with our fish oil supplement.

Why do you use small fish?

This product contains anchovies as they are naturally healthy & offer a better natural fat profile. Plus they are lower down the marine food chain & are therefore less likely to contain heavy metals & pollutants like PCBs.

Is your Puro High Strength Omega-3 screened for mercury and other heavy metals?

We can confirm that all of our products are tested for microbial, heavy metals, herbicides, and pesticides as part of the GMP code of practice during the manufacturing process.

What makes Purolabs different?

At Purolabs, we don't just add more ingredients—we choose the right ones.

Every supplement contains premium, science-backed nutrients in their most bioavailable forms, so your body actually absorbs and uses them.

We're different because we maintain a 100% clean label with no fillers, additives, or synthetic nasties—just pure, potent ingredients.

Our products are made right here in the UK to ISO 22000 certified and GMP standards, ensuring complete transparency from sourcing to delivery.

We use superior bioavailable forms of nutrients that deliver real results, not expensive waste, and we're so confident in our products that we offer a 60-day money-back guarantee.

Where is Purolabs based?

Purolabs is a small, family-run business based in South London. Founded by husband and wife Adam and Marilia, we're an independent UK company—not a faceless corporation. This means we can put quality and customers first, without shareholders pushing us to cut corners.

From our London base, we personally oversee every aspect of production and our friendly team is here to help seven days a week. When you choose Purolabs, you're supporting a local British business that genuinely cares about your wellbeing.

All orders are sent promptly from our UK warehouse within 24 business hours, so you'll receive your supplements quickly whichever option you choose.

Do you offer a money back guarantee?

We believe in our products and want you to feel confident trying them risk-free so we offer a 60-day money-back guarantee.

If you're not completely satisfied with your supplements for any reason, simply return any unused bottles within 60 days of purchase for a full refund - no questions asked.

    Great Quality and no aftertaste

    These omega 3 tablets are great. I’ve been taking them for about 4 months now and I definitely feel a bit less creaky in my kneck and joints. They are easy to swallow and best of all there is no aftertaste at all - exactly as it should be.

    Omega-3 High strength no fishy burps!

    I always use this Omega-3 High strength supplements and notice that my body does not ache so much especially during the colder months and as a student I need all the help I can get as these supplements are great for eye sight and cognitive function and the bonus is that I do not have fishy smelling burps.
