Heart Failure:

• Oxidative Damage: Oxidative stress is a significant contributor to heart failure, leading to the deterioration of cardiac muscle function and the remodelling of heart structure. This stress triggers a cascade of detrimental effects, including increased inflammation and fibrosis, which compromise the heart's ability to pump effectively. [6]
• Antioxidant Support: Antioxidants provide a critical defence mechanism for the heart by minimising oxidative damage and inflammation, thereby supporting the maintenance of cardiac function and reducing the progression of heart failure.

Hypertension:

• Oxidative Damage: Oxidative stress induces hypertension by impairing the endothelial function of blood vessels, leading to vasoconstriction, increased arterial stiffness and high blood pressure. This dysfunction is compounded by the reduction in the availability of nitric oxide, a key molecule in regulating blood vessel relaxation and blood pressure. [7]
• Antioxidant Support: By scavenging reactive oxygen species, antioxidants help to restore endothelial function and promote vasodilation, thereby aiding in the management of hypertension.

Immune System Dysfunction:

• Oxidative Damage: Oxidative stress undermines the immune system's integrity by damaging immune cells, reducing their proliferation and impairing their function. This weakening of the immune response leaves the body more susceptible to infections, diseases and impaired healing.
• Antioxidant Support: Antioxidants enhance immune system performance by protecting immune cells from oxidative damage, supporting their viability and function. This reinforcement not only bolsters the body's defence mechanisms but also aids in the prevention of oxidative stress-related immune deficiencies.

Inflammation:

• Oxidative Damage: Oxidative stress stands at the forefront of initiating and perpetuating the inflammatory cascade by engaging and amplifying pro-inflammatory pathways and the release of cytokines. This relentless cycle of chronic inflammation acts as a pivotal contributor to a wide spectrum of health challenges, ranging from the insidious onset of autoimmune disorders to the progressive deterioration seen in cardiovascular and neurodegenerative diseases. The sustained inflammatory response, underpinned by oxidative stress, not only disrupts normal cellular function but also sets the stage for long-term tissue damage and disease manifestation. [7], [8]
• Antioxidant Support: Antioxidants provide a multifaceted approach to disrupting the deleterious cycle of oxidative stress and chronic inflammation. By effectively scavenging free radicals and mitigating their oxidative potential, these compounds significantly down-regulate the inflammatory process at a molecular level. This strategic intervention extends beyond mere symptom relief, addressing the root cause of inflammation and thereby fostering an environment conducive to cellular repair and systemic health.

• Antioxidant Support: Antioxidants play a protective role in male reproductive health by neutralising free radicals and enhancing sperm quality. This protective action is essential for improving fertility outcomes and promoting reproductive health.

Multiple Sclerosis (MS):

• Oxidative Damage: MS is a debilitating autoimmune disease that targets the central nervous system, particularly attacking the protective myelin sheath that surrounds nerve fibres. Oxidative stress is a significant contributor to this process, where an imbalance between the production of reactive oxygen species and the body's ability to detoxify these reactive intermediates or repair the resulting damage leads to deterioration of neural tissues. This oxidative damage not only accelerates the demyelination process but also impairs neuronal function, exacerbating the neurodegenerative aspects of MS and influencing the severity and progression of the disease. [12]
• Antioxidant Support: In the context of MS, antioxidants serve as a critical line of defence by offering neuroprotective benefits that can ameliorate the impact of oxidative stress on the nervous system. These compounds work by neutralising reactive oxygen species, thereby reducing oxidative damage to neurons and the myelin sheath. The neuroprotective effect of antioxidants not only has the potential to slow down the progression of MS but also supports the preservation of nerve function and mitigates the severity of symptoms.

Neurodegenerative Diseases:

• Oxidative Damage: In neurodegenerative diseases like Alzheimer's and Parkinson's, oxidative stress is a key factor that exacerbates neuronal damage and accelerates the progression of these conditions. The brain's high oxygen consumption rate makes it particularly vulnerable to oxidative damage, leading to the accumulation of damaged proteins and neuronal loss that characterise these diseases. [13]
• Antioxidant Support: Antioxidants play a vital role in neuroprotection by scavenging free radicals and reducing oxidative stress and inflammation with in the brain, thereby potentially slowing the neurodegenerative process.

Premature Ageing:

• Oxidative Damage: The accumulation of oxidative damage to cells, tissues and DNA is a major factor in the ageing process, contributing to visible signs of ageing and the decline of bodily functions. [14]
• Antioxidant Support: Antioxidants are key players in combatting premature ageing by neutralising free radicals and reducing oxidative stress, which helps preserve cellular DNA and helps maintain a healthy outward.

Respiratory Conditions:

• Antioxidant Support: Antioxidants serve as protectors of the respiratory system by neutralising free radicals, reducing inflammation and supporting the maintenance of healthy lung function, thereby aiding in the management of asthma symptoms and overall respiratory health.

Rheumatoid Arthritis:

• Oxidative Damage: Rheumatoid arthritis (RA) is an autoimmune condition characterised by chronic inflammation and oxidative stress within the joints. In RA, the overproduction of reactive oxygen species contributes to inflammation and tissue damage, exacerbating joint pain, swelling and destruction. [16]
• Antioxidant Support: Antioxidants offer therapeutic potential in managing RA by neutralising reactive oxygen species and reducing oxidative damage to joint tissues.

Systemic Lupus Erythematosus

• Oxidative Damage: Systemic Lupus Erythematosus (SLE) is a complex autoimmune disease characterised by widespread inflammation and tissue damage across multiple organ systems. Oxidative stress plays a pivotal role in the pathophysiology of SLE, amplifying inflammation and triggering auto-antibody production. The increased oxidative burden can damage cellular components, leading to the presentation of auto-antigens and further stimulating the autoimmune response. This oxidative environment fosters the progression of SLE, contributing to its manifestations and complications. [17]
• Antioxidant Support: In the context of SLE, antioxidants act as crucial allies in moderating the disease's impact. By reducing oxidative stress, antioxidants can attenuate the inflammatory processes and cellular damage that characterise SLE. This supportive action aids in controlling disease activity, preserving organ function and improving the quality of life for those affected by lupus.

Type 1 Diabetes:

• Oxidative Damage: In Type 1 Diabetes, the autoimmune assault on the pancreas leads to the targeted destruction of beta cells, responsible for insulin production. Oxidative stress is a critical factor that exacerbates this destruction. The excessive accumulation of reactive oxygen species (ROS) can overwhelm the natural antioxidant defences of beta cells, resulting in their dysfunction and death. This process significantly contributes to the onset of Type 1 Diabetes, as the body loses its ability to regulate blood glucose levels effectively. [18]
• Antioxidant Support: The role of antioxidants in protecting pancreatic beta cells from oxidative stress is of paramount importance. By scavenging ROS, antioxidants can mitigate the oxidative damage that precipitates beta cell destruction. This protective mechanism suggests that increased intake of antioxidants, through diet or supplementation, could potentially delay or reduce the risk of developing Type 1 Diabetes.

Vision Problems:

• Oxidative Damage: Vision health is intricately linked to oxidative stress, which plays a significant role in the deterioration of eye health, including conditions such as age-related macular degeneration (AMD). The accumulation of oxidative damage within the macula—the central part of the retina responsible for high-resolution vision—can lead to a decline in visual acuity and, ultimately, loss of central vision. [19]
• Antioxidant Support: Antioxidants provide a critical line of defence for preserving eye health and preventing the progression of diseases like AMD. Nutrients such as lutein and zeaxanthin, found in high concentrations within the eye, filter harmful blue light and neutralise free radicals, thus protecting the retina from oxidative stress.

Factors Contributing to Reduced Antioxidant Levels

Reduced antioxidant levels can result from various factors that disturb the balance between free radicals and the body's antioxidant defences. Recognising these factors is crucial for the upkeep of a strong antioxidant protection system. Below are key elements that can lead to a decrease in antioxidant levels:

• Ageing and Nutrient Absorption: With advancing age, the body's ability to absorb essential nutrients diminishes. Reduced stomach acid levels, a lack of digestive enzymes and intestinal issues can lead to lower absorption rates of antioxidants and other vital nutrients.
• Impact of Chronic Inflammation on Antioxidant Requirements: Chronic inflammation, which can manifest across a wide spectrum of health conditions beyond autoimmune disorders, joint diseases and persistent infections, significantly escalates the body's oxidative stress. This pervasive increase in oxidative stress amplifies the demand for antioxidants, essential for neutralising harmful free radicals and reinforcing the body's defence systems. Enhanced antioxidant intake becomes imperative to mitigate the wide-ranging effects of chronic inflammation and support the maintenance of optimal health.
• Stress Increase Oxidative Stress: Prolonged stress can accelerate the body's production of free radicals, which in turn contributes to the development of oxidative stress. This heightened state of oxidative imbalance necessitates an increased intake of antioxidants to neutralise these free radicals and restore equilibrium, mitigating the damaging effects on the body.
• Environmental Factors and Their Impact on Antioxidant Levels: Exposure to a variety of environmental factors, including not only widespread air pollution but also cigarette smoke, chemicals and even everyday cleaning products, can significantly elevate oxidative stress. This increased stress challenges the body's antioxidant defences, often surpassing its natural capacity to combat free radical damage. Enhancing antioxidant intake becomes crucial to protect against this heightened oxidative stress, emphasising the importance of being proactive about environmental health risks.
• Digestive Health and Antioxidant Absorption: Gastrointestinal health is crucial for the effective absorption of antioxidants, essential for combating oxidative stress. Conditions like leaky gut syndrome, celiac disease and Crohn's disease disrupt the digestive tract's ability to efficiently absorb nutrients, leading to reduced antioxidant uptake and increased vulnerability to oxidative damage. These disorders not only impair the gut's lining, hindering nutrient absorption, but also contribute to a cycle of inflammation and oxidative stress, exacerbating the body's antioxidant deficiency. Addressing digestive health through dietary adjustments, nutritional supplements and lifestyle changes is vital to enhancing antioxidant absorption, thereby strengthening the body's defence against oxidative stress and supporting overall health.
• Inadequate Detoxification: A compromised detoxification system can lead to toxin accumulation, which in turn elevates oxidative stress through the overproduction of free radicals. This not only drains the body's antioxidant resources but also disrupts cellular functioning, propelling a cycle of oxidative damage that can predispose individuals to inflammation and chronic conditions. Additionally, inefficient detoxification can result in nutrient depletion, further diminishing the body's antioxidant production capabilities.
• Poor Dietary Choices: Our diet significantly influence antioxidant levels in the body, a lack of fruits, vegetables, herbs, algae, nuts and seeds can lead to a deficiency in antioxidants, leaving the body more vulnerable to cellular damage and chronic diseases. Antioxidants neutralise harmful free radicals, preventing oxidative damage that accelerates ageing and increases disease risk. Therefore, incorporating a variety of antioxidant-rich foods is crucial for maintaining optimal health, supporting cellular repair and enhancing the body's natural defences against environmental and biological stressors.
• Health Conditions and Antioxidant Demand: Chronic health conditions such as diabetes, heart disease and neurodegenerative disorders significantly increase the body's demand for antioxidants due to elevated levels of oxidative stress, which can cause extensive cellular damage and accelerate disease progression. For instance, the high blood sugar levels in diabetes, the plaque formation in heart disease and neuronal degradation in conditions like Alzheimer's and Parkinson's disease, all stem from the harmful effects of oxidative stress. Consequently, incorporating a diet rich in antioxidants is essential for neutralising free radicals, providing a protective shield for cells and potentially improving health outcomes. This approach underscores the importance of antioxidant-rich nutrition in managing chronic illnesses, highlighting how dietary choices can support medical interventions to enhance quality of life and slow the progression of these conditions.

Impact of Medications on Antioxidants:

The relationship between certain medications and oxidative stress underscores a complex interaction that can impact the body's antioxidant levels and overall health.

• Antibiotics and Oxidative Stress: Some antibiotics including Tetracyclines and Fluoroquinolones are known to increase oxidative stress within the body. This elevation can lead to a decrease in antioxidant levels, as the body uses up its stores to combat the excess free radicals produced as a side effect of the medication. Consequently, individuals taking these antibiotics may require additional antioxidant intake through diet or supplements to restore balance and protect cells from oxidative damage.
• Chemotherapy and Free Radical Production: Chemotherapy, a common treatment for cancer, works by targeting rapidly dividing cells but can also result in the production of free radicals, contributing to increased oxidative stress. This rise in oxidative stress can damage healthy cells and tissues, making the consumption of antioxidants more critical for patients undergoing chemotherapy. Example of medications include Doxorubicin, Cisplatin and Carboplatin. Antioxidants help neutralise these free radicals, potentially reducing the side effects of chemotherapy and supporting the body's resilience during treatment.
• Antipsychotics and Oxidative Effects: Antipsychotic medications including Haloperidol, Clozapine and Olanzapine used to treat mental health disorders such as schizophrenia and bipolar disorder, can induce oxidative stress. This oxidative stress can compromise cell health and function, particularly in the brain, where it might contribute to further neurological imbalances. Ensuring adequate antioxidant intake can help mitigate some of the oxidative effects associated with long-term use of these medications.
• NSAIDs' Impact on Oxidative Stress: Non-steroidal anti-inflammatory drugs (NSAIDs), commonly utilised for their analgesic and anti-inflammatory properties, have been identified as a source of increased oxidative stress when used for prolonged periods. This escalation in oxidative stress not only drains the body's antioxidant reserves, undermining its defences against harmful free radicals, but can also contribute to the breakdown of intestinal integrity. The gastrointestinal side effects of NSAIDs, including damage to the lining of the stomach and intestines including Leaky Gut Syndrome, can exacerbate oxidative stress by impairing nutrient absorption and leading to further inflammation. This disruption in intestinal health can create a feedback loop that intensifies oxidative stress throughout the body. Examples of NSAID's include Ibuprofen, Naproxen and Aspirin. Consequently, those who rely on NSAIDs for chronic pain management should consider integrating antioxidant-rich foods and supplementation into their diets to mitigate these risks. Additionally, exploring alternative pain relief methods and closely monitoring NSAID intake can help maintain both intestinal health and the balance of oxidative stress, preserving the body's overall well-being.
• Paracetamol: While paracetamol (acetaminophen) is commonly used for its effective pain-relieving and fever-reducing properties, its excessive or prolonged consumption can challenge the body's antioxidant defences, particularly in the liver. The metabolism of paracetamol produces N-acetyl-p-benzoquinone imine (NAPQI), a potentially harmful compound that is typically neutralised by the antioxidant glutathione. However, in cases of overdose or depleted glutathione reserves, NAPQI accumulation can induce oxidative stress and liver damage. To counteract these risks, maintaining a diet rich in antioxidants and considering supplements like N-acetylcysteine to support glutathione levels can be crucial in protecting liver health and balancing the body’s oxidative state during paracetamol use.

Impact of Lifestyle on Antioxidants:

Lifestyle choices play a significant role in influencing antioxidant levels in the body, impacting overall health and the ability to counteract oxidative stress.

• Smoking: Smoking is a major source of free radicals. This habit significantly increases the body's oxidative burden, depleting its natural antioxidant defences and necessitating a higher intake of antioxidants to mitigate the damage. The harmful chemicals in tobacco smoke can lead to a wide range of health issues, including cardiovascular disease, lung conditions and cancer, all exacerbated by oxidative stress. Adopting a smoke-free lifestyle and increasing consumption of antioxidant-rich foods can help restore antioxidant balance and reduce health risks.
• Alcohol Consumption: Frequent alcohol consumption challenges the body's antioxidant reserves, leading to enhanced oxidative stress, particularly in the liver, an organ critical for detoxification. Excessive alcohol can cause liver inflammation and damage, conditions fuelled by oxidative stress. Moderating alcohol intake and ensuring a diet high in antioxidants can support liver health and help maintain adequate antioxidant levels to combat the oxidative effects of alcohol.
• Stimulant Use: The use of stimulant drugs such as cocaine and methamphetamine is associated with increased production of free radicals, contributing to oxidative stress and potential damage to body tissues. This can accelerate the ageing process and increase susceptibility to neurological and cardiovascular diseases.
• Inhalant Exposure: Exposure to certain inhalants — ranging from industrial chemicals and household cleaners to aerosols and vaping products — poses a risk by inducing oxidative stress and harming lung tissue. Inhalants and vaping materials release chemicals and particles capable of generating free radicals, similarly to tobacco smoke, which can deteriorate lung function and foster respiratory diseases. Reducing exposure to these substances and fortifying your antioxidant intake through diet and supplements is vital in lessening the oxidative stress impact on lung health.
• Inactivity: A sedentary lifestyle may compromise the body's natural antioxidant defence system, making it less efficient at neutralising free radicals. Physical activity has been shown to boost antioxidant levels and improve the body's ability to combat oxidative stress, enhancing overall health and reducing the risk of chronic diseases. Incorporating regular exercise into daily routines can strengthen the antioxidant defence system and improve the body's resilience against oxidative damage.
