Oxidative stress is one of the most overlooked drivers of ageing, fatigue & inflammation
Antioxidant support
STMNA Bioactives supplement ‘Healthspan’ delivers clinically studied antioxidant compounds designed to help defend, protect and restore balance at a cellular level
What is Oxidative Stress?
The Hidden Impact of Oxidative Stress
Everyday, your body is exposed to stress from internal and external factors such as environmental pollution, poor sleep, toxins, microplastics, chronic stress, infections, viruses, jet lag and so on.
These factors generate free radicals - unstable molecules that can damage cells, DNA and accelerate:
• Premature ageing
• Fatigue & low energy
• Inflammation
• Skin dullness
• Cognitive fog
Antioxidants help neutralise this damage.
Supplements for Oxidative Stress and Cellular Repair
Our cells are exposed to more oxidative stress than ever before - a process caused by free radicals damaging healthy cells. These free radicals are produced through everyday exposures such as pollution, UV radiation, poor sleep, stress and highly processed foods.
Over time, oxidative stress can accelerate cellular ageing, increase inflammation and reduce the body’s ability to repair and protect itself.
Supporting the body with antioxidant-rich compounds helps defend cells against this damage, promoting resilience, energy and long-term vitality.
Here are some of the ways consistent antioxidant support through supplements that benefit your body.
Protect Cells from Free Radical Damage
The Positive Impact of Oxidative
Free radicals are unstable molecules that damage healthy cells and accelerate ageing. Antioxidants help neutralise these molecules before they can cause harm.
Supporting the body’s antioxidant defence system helps maintain cellular integrity and long-term health.
Support Healthy Ageing
The Positive Impact of Oxidative
Oxidative stress is one of the key biological drivers of ageing.
By helping defend cells from cumulative oxidative damage, antioxidant compounds support the body’s natural ability to maintain healthy tissues, organs and systems as we age.
Promote Cardiovascular Protection
The Positive Impact of Oxidative
Oxidative damage can affect blood vessels and circulation over time.
Antioxidant-rich plant compounds help support healthy vascular function and protect the cardiovascular system from oxidative strain.
Support Skin & Collagen Health
The Positive Impact of Oxidative
Oxidative stress contributes to visible signs of ageing such as wrinkles, dull skin and loss of elasticity.
By protecting collagen and skin cells from free radical damage, antioxidants help maintain healthier, more resilient skin over time.
Support Brain & Cognitive Function
The Positive Impact of Oxidative
The brain is particularly vulnerable to oxidative stress due to its high energy demands.
Providing antioxidant support helps protect neural cells, supporting memory, focus and long-term cognitive health.
Best Natural Ingredients for Oxidative Stress (Backed by Research)
Certain plant bioactives have been extensively studied for their ability to help neutralise free radicals and support the body’s natural cellular repair systems. Healthspan by STMNA Bioactives contains three of the most researched natural antioxidants known to support cellular protection and resilience.
CURCUMIN (FROM TURMERIC)
Powerful defence against oxidative damage
Curcumin is widely recognised for its potent antioxidant and anti-inflammatory properties. It helps neutralise free radicals while also supporting the body’s own antioxidant enzymes, strengthening the body’s natural defence systems. By protecting cells from oxidative damage, curcumin supports healthier tissues, improved recovery and long-term cellular resilience.
Resveratrol (Reynoutria Japonica Root)
Cellular protection linked to longevity science
Resveratrol is a polyphenol extensively studied for its role in protecting cells from oxidative stress and supporting healthy ageing. It helps activate key cellular pathways involved in repair, mitochondrial function and metabolic balance. By defending cells from oxidative damage, resveratrol contributes to long-term vitality, cardiovascular health and cognitive resilience.
Grape Seed Extract (Vitis Vinifera)
Antioxidant protection for cells and collagen
Grape Seed Extract is rich in procyanidins, a class of powerful antioxidants that help protect cells from free radical damage. These compounds support healthy circulation while also helping defend collagen fibres from oxidative stress, which can contribute to visible skin ageing. By supporting both cellular protection and collagen integrity, grape seed extract plays an important role in maintaining vitality from the inside out.

ANTIOXIDANTS & OXIDATIVE STRESS FAQS
Oxidative stress occurs when free radicals build up faster than the body can neutralise them. Over time, this can lead to cellular damage, inflammation, and accelerated ageing.
Antioxidants help neutralise free radicals, protecting cells from damage. This supports overall cellular health, recovery, and long-term vitality.
Effective antioxidant supplements often include plant-derived compounds such as curcumin, resveratrol, and grape seed extract, which are known for supporting cellular protection.
Healthspan combines multiple bioactive plant compounds that work together to support the body’s natural antioxidant systems, helping defend against daily environmental stressors.
Common contributors include poor sleep, chronic stress, processed foods, environmental toxins, UV exposure, and even intense physical activity.
Yes, oxidative stress plays a major role in visible ageing. It can contribute to collagen breakdown, reduced skin elasticity, and dullness over time.
This is a gradual process. Some people notice improvements in energy and recovery within weeks, but consistent support over several months delivers more meaningful long-term benefits.
Both are important. A nutrient-rich diet provides a strong foundation, while supplements offer more concentrated and consistent support when needed.
Anyone exposed to modern lifestyle stressors can benefit, particularly those managing stress, fatigue, environmental exposure, or looking to support healthy ageing and recovery.
