Formula Science & Benefits
Quercetin, Trans-Resveratrol, and Green Tea Extract (with EGCG) are studied for their antioxidant properties. The formula also contains Vitamin E and Selenium, which help protect cells from oxidative stress. Together, these ingredients support antioxidant defences and cellular protection, which are important aspects of healthy aging.
Trans-Resveratrol and Co-Enzyme Q10 are widely studied in the context of cardiovascular health. CoQ10 also plays an important role in cellular energy production, including in energy demanding tissues such as the heart.
B vitamins (B3, B6, B12), Betaine and CoQ10 play key roles in various metabolic processes, including energy production. Vitamins B6 and B12 support normal energy metabolism and help reduce tiredness and fatigue. Optimising these processes may contribute to overall healthy aging.
Quercetin and Bromelain are widely studied for their role in healthy inflammatory responses. Maintaining a balanced inflammatory response may support long-term health and healthy aging.
Black Pepper Extract (BioPerine®) plays a role in supporting the bioavailability and absorption of certain nutrients in the formula, helping the body effectively utilise them and support their potential benefits.
Our Biophotonic Glass - The Ideal Packaging For Your Valuable Content
-
Preservation of Contents:Biophotonic glass filters out most visible light while allowing in beneficial violet, ultraviolet, and infrared light. This helps protect the contents from light-induced damage, extending their shelf life and effectiveness.
-
Potential Energizing Effects:The violet light that penetrates the glass can energize the contents, potentially enhancing their beneficial properties. This is a concept rooted in biophotonics, the study of light and energy in living systems.
-
Sustainability:Biophotonic glass is a reusable and recyclable material, making it an environmentally friendly alternative to plastic packaging.
-
Maintaining Freshness:In scientific tests, when compared to other types of glass, biophotonic glass has a significantly better storage quality.
-
Our Advice:Keep the glass and use it in the kitchen to store herbs, spices, nuts, or teas
What is Essentials I XR and what is it designed for?
Essentials I XR is a comprehensive antioxidant and healthy aging formulation combining Quercetin, Trans-Resveratrol, Bromelain, Betaine, Co-Enzyme Q10, EGCG, Vitamin E, BioPerine®, Vitamins B6, B3, B12, and Selenium in one convenient daily time-released (XR) capsule.
The formulation brings together nutrients and bioactive compounds studied for their roles in antioxidant protection, cellular health, energy metabolism and healthy inflammatory responses. These biological processes are relevant to healthy aging and are studied in the broader context of the
Hallmarks of Aging.
Why does Essentials I XR combine Quercetin and Trans-Resveratrol?
Quercetin and Trans-Resveratrol are naturally occurring polyphenols that have been widely studied for their antioxidant properties and roles in cellular health and healthy aging. Both compounds have been studied individually and in combination, with laboratory research also investigating synergistic antioxidant interactions between them under certain conditions.
Essentials I XR combines 200mg Quercetin and 100mg Trans-Resveratrol with complementary nutrients and bioactive compounds, including Co-Enzyme Q10, EGCG, Bromelain, Betaine and Selenium, creating a broader antioxidant and healthy aging formulation rather than relying on a single compound.
What are antioxidants and why are they important for healthy aging?
Antioxidants are compounds that help protect cells from oxidative stress caused by free radicals and other reactive molecules. Oxidative stress occurs when the production of these reactive molecules exceeds the body's antioxidant defences and can contribute to cellular damage over time.
Oxidative stress is closely linked to several biological processes associated with aging and is widely studied in healthy aging and longevity research. Essentials I XR combines multiple antioxidant and antioxidant-supporting compounds, including Quercetin, Trans-Resveratrol, Co-Enzyme Q10, EGCG, Vitamin E and Selenium, to support the body's antioxidant defences and help protect cells from oxidative stress.
Why does Essentials I XR contain BioPerine®?
The patented Black Pepper Extract (BioPerine®) in Essentials I XR is standardized to contain a minimum of 95% piperine and plays a key role in supporting bioavailability and absorption of certain nutrients in the formula, helping the body utilise them more effectively.
What is a time-released (XR) capsule?
Essentials I XR uses a time-released (XR) capsule manufactured by a Swiss pharmaceutical company and designed to delay the release of its contents beyond the stomach. This differs from conventional immediate-release capsules, which release their contents more rapidly after ingestion. By controlling where and how the ingredients are released, the XR capsule is designed to support their delivery and bioavailability.
Can I take Essentials I XR with other supplements?
Yes, Essentials I XR can be incorporated alongside other Juvina Bioscience supplements. In fact, Essentials I XR and Cell Activator XR I NMN are available together as our Essentials Bundle XR, combining the antioxidant and healthy aging formulation in Essentials I XR with 500mg Uthever® NMN.
As individual needs and supplement routines vary, anyone who is pregnant, breastfeeding, taking medication, managing a medical condition or using multiple supplements should consult a qualified healthcare professional before using this or any dietary supplement. Essentials I XR is not intended for children.
Have the ingredients in Essentials I XR been studied in humans?
Yes. Key ingredients in Essentials I XR, including Quercetin, Trans-Resveratrol, Co-Enzyme Q10, EGCG and Selenium, have been investigated in human clinical research. Studies have explored their roles across areas such as antioxidant activity, oxidative stress, energy metabolism and other aspects of cellular health.
Essentials I XR brings these ingredients together in a comprehensive formulation alongside Bromelain, Betaine, Vitamin E, B vitamins and BioPerine®.
