How does it work?

Modern life asks a great deal of your body. Between environmental toxins, processed food and the physical strain of a demanding lifestyle, your body often ends up in a state of chronic systemic inflammation.

That leads to stiff joints, bloating, sluggish digestion and metabolic fatigue.

Purelis harnesses the multi-pathway power of Nigella Sativa to bring the body back into balance. The heavy lifting is done by thymoquinone (TQ), a bioactive compound that helps to “switch off” inflammatory triggers at the cellular level.

The catch is that TQ is known to be volatile and prone to oxidation. While standard oils often degrade before they even reach the shelf, our formula is bio-locked with MCT oil.

This ensures that our 5% TQ concentration, the highest in the industry, stays stable and potent, delivering the active nutrients straight to your body.

What can Purelis help with?

Our stabilised 5% TQ formula is designed to support your body’s essential functions:

  • Supports a healthy inflammatory response: helps maintain joint comfort and mobility by supporting the body’s natural response to everyday physical stress.
  • Promotes digestive balance: soothes the digestive tract and supports a healthy microbiome, for better gut comfort and better nutrient absorption.
  • Strengthens antioxidant defence: delivers a powerful thymoquinone shield to help neutralise free radicals and protect cells from oxidative stress.
  • Maintains metabolic function: supports healthy metabolic efficiency, helping to keep your energy steady throughout the day.
  • Guaranteed 5% TQ potency: our MCT-stabilised formula gives you a highly concentrated, bioavailable dose of black seed oil’s most active compound, in every serving.

When will I see results?

Consistency is key to supporting your internal systems. Because our formula is stabilised for maximum absorption, the benefits build over time:

  • 1 to 2 weeks: most users notice improved digestive comfort and less heaviness after meals.
  • 4 to 6 weeks: as TQ levels stabilise in your body, you may feel more supple joints and more consistent daily energy.
  • 3 months and beyond: optimal systemic support. Long-term use strengthens your body’s natural defences and supports lasting cellular health.

Who can use it?

Purelis is designed for anyone who wants to fortify their body against the daily stresses of a demanding lifestyle. It is particularly effective for:

  • Active people who want to support their natural recovery process and keep their joints comfortable.
  • Those seeking digestive balance who want a stable, highly concentrated oil to support a healthy gut microbiome.
  • High performers who need to maintain steady metabolic energy and avoid the mid-afternoon slump.
  • Discerning consumers who want the most stable and most bioavailable form of black seed oil on the market, without the oxidation of standard formulas.

Black seed oil has been used safely for more than 3,000 years around the world. As always, if you have any doubts, it is a good idea to speak to your healthcare professional.

How long until I receive it?

To keep our 5% TQ potent and effective, our black seed oil is cold-pressed and encapsulated in a temperature-controlled facility. This process prevents the oxidation that ruins standard oils.

Exceptional sourcing, cold-pressed and 5% thymoquinone

Our Nigella Sativa is grown in the high-altitude soils of the Himalayan region, which maximises its bioactive profile. It is then cold-pressed and standardised to 5% thymoquinone, a concentration well above that of most brands.
