Let’s start with WHAT is Oxidative Stress?

Oxidative stress is a physiological imbalance between the production of reactive oxygen species (ROS) and the body’s ability to detoxify or repair the resulting damage.

Reactive oxygen species, including free radicals like superoxide anion (O2•−), hydroxyl radical (•OH), and non-radical molecules like hydrogen peroxide (H2O2), are natural byproducts of normal cellular metabolism.

Under normal circumstances, the body has defense mechanisms, including antioxidants like enzymes (e.g., superoxide dismutase, catalase) and non-enzymatic antioxidants (e.g., vitamins C and E), to neutralize ROS and prevent oxidative damage.

However, when there is an excess of ROS production or a deficiency in antioxidant defenses, oxidative stress can occur.

Oxidative stress can lead to damage to various cellular components, including lipids, proteins, and DNA.

For example:

Lipid Peroxidation: ROS can react with lipids in cell membranes, leading to lipid peroxidation. This process produces lipid hydroperoxides and other reactive intermediates, which can disrupt membrane integrity and function.
Protein Oxidation: ROS can oxidize amino acid residues in proteins, leading to protein misfolding, aggregation, and loss of function. Oxidative modification of proteins can impair enzymatic activity, signal transduction pathways, and structural integrity.
DNA Damage: ROS can directly damage DNA, causing DNA strand breaks, base modifications, and DNA cross-links. Oxidative DNA damage can lead to mutations, genomic instability, and increased risk of diseases like cancer.

Oxidative stress has been implicated in the pathogenesis of various diseases and conditions, including neurodegenerative diseases (e.g., Alzheimer’s disease, Parkinson’s disease), cardiovascular diseases (e.g., atherosclerosis, hypertension), metabolic disorders (e.g., diabetes, obesity), inflammatory conditions (e.g., rheumatoid arthritis, inflammatory bowel disease), and aging-related degenerative processes.

Factors that can contribute to oxidative stress include environmental pollutants, cigarette smoke, UV radiation, certain medications, chronic inflammation, poor diet (e.g., high in processed foods, low in antioxidants), and lifestyle factors (e.g., sedentary behavior, excessive alcohol consumption). Minimizing exposure to oxidative stressors, adopting a healthy lifestyle, and consuming a diet rich in antioxidants can help mitigate oxidative stress and promote overall health and well-being.

How does OVER Exercise & UNDER Recovery impact our health?

Overtraining or excessive exercise can have several negative effects on the body, including impacting oxidative stress, chronic inflammation, gut health, and aging:

Oxidative Stress: Intense or prolonged exercise can lead to an increase in oxidative stress due to the production of reactive oxygen species (ROS) during aerobic metabolism and muscle contraction. Over time, excessive oxidative stress can damage cellular structures, including lipids, proteins, and DNA, contributing to tissue inflammation and dysfunction.
Chronic Inflammation: Overtraining can trigger chronic inflammation in the body, characterized by an imbalance between pro-inflammatory and anti-inflammatory signaling pathways. Chronic inflammation is associated with various health issues, including increased risk of cardiovascular disease, metabolic disorders, and autoimmune conditions.
Leaky Gut: Overtraining may compromise gut barrier function and contribute to increased intestinal permeability, commonly referred to as leaky gut syndrome. Intense exercise can lead to changes in gut physiology, including alterations in blood flow, intestinal motility, and immune function, which may contribute to gut barrier dysfunction and allow harmful substances to leak into the bloodstream, triggering inflammation and immune responses.
Gut Dysbiosis: Excessive exercise may disrupt the balance of gut microbiota, leading to gut dysbiosis, characterized by an imbalance between beneficial and pathogenic bacteria. Factors such as increased intestinal permeability, altered gut transit time, and changes in mucosal immunity associated with overtraining can contribute to gut dysbiosis, which may further exacerbate inflammation and metabolic dysfunction.
Aging: Chronic overtraining and excessive exercise can accelerate aging processes in the body by promoting oxidative damage, inflammation, and metabolic dysfunction. Prolonged exposure to oxidative stress and chronic inflammation can contribute to cellular senescence, telomere shortening, and other hallmarks of aging, increasing the risk of age-related diseases and functional decline.

Overall, while regular exercise is essential for maintaining overall health and well-being, it’s essential to avoid excessive or prolonged bouts of exercise that may lead to overtraining and negative health consequences. Balancing exercise intensity, duration, and recovery periods is crucial for optimizing health outcomes and minimizing the risk of oxidative stress, inflammation, gut dysfunction, and premature aging. Listening to your body, prioritizing adequate rest and recovery, and adopting a well-rounded approach to fitness that includes strength training, flexibility, and cardiovascular exercise can help promote long-term health and vitality.

How do you test and not guess if your body is under stress?

There are several methods to measure oxidative stress in the body, including blood chemistry tests and functional lab markers.

Here are some commonly used markers to evaluate oxidative stress:

Markers of Lipid Peroxidation:
- Malondialdehyde (MDA): MDA is a byproduct of lipid peroxidation and is often measured as an indicator of oxidative damage to cell membranes.
- F2-isoprostanes: F2-isoprostanes are prostaglandin-like compounds formed by the non-enzymatic peroxidation of arachidonic acid and are considered reliable markers of oxidative stress.
Markers of Protein Oxidation:
- Protein carbonyls: Protein carbonylation is a common marker of protein oxidation and can be measured to assess oxidative damage to proteins.
- 3-nitrotyrosine: Nitrotyrosine is formed by the reaction of tyrosine residues with reactive nitrogen species, including peroxynitrite, and serves as a marker of oxidative/nitrosative stress.
Markers of DNA Damage:
- 8-hydroxy-2’-deoxyguanosine (8-OHdG): 8-OHdG is a biomarker of oxidative DNA damage and is frequently measured in urine or serum samples to assess oxidative stress-induced DNA lesions.
Antioxidant Enzymes and Molecules:
- Superoxide Dismutase (SOD), Catalase (CAT), and Glutathione Peroxidase (GPx): These are antioxidant enzymes that help neutralize reactive oxygen species. Reduced levels of these enzymes may indicate increased oxidative stress.
- Glutathione (GSH): GSH is an important intracellular antioxidant that plays a key role in detoxifying reactive oxygen species and maintaining cellular redox balance.
Markers of Total Antioxidant Capacity:
- Total Antioxidant Capacity (TAC): TAC assays measure the ability of biological samples to neutralize free radicals and can provide an overall assessment of antioxidant status in the body.

It’s important to note that optimal levels of these markers may vary depending on individual factors such as age, sex, genetics, and overall health status. Additionally, oxidative stress is a dynamic process influenced by various factors, including lifestyle, diet, environmental exposures, and disease states. Therefore, interpreting oxidative stress markers in the context of a comprehensive clinical assessment is essential for understanding an individual’s oxidative stress status and potential health implications.

What genetic markers influence our response to Oxidative Stress?

Genetics can influence oxidative stress levels through several mechanisms, including variations in genes involved in antioxidant defense pathways, DNA repair mechanisms, and other cellular processes related to redox homeostasis. Here’s how genetics can impact oxidative stress levels:

Antioxidant Enzymes: Genetic variations in genes encoding antioxidant enzymes such as superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GPx) can affect their activity levels or efficiency. For example, certain single nucleotide polymorphisms (SNPs) in the SOD2 gene, which encodes mitochondrial SOD, have been associated with altered antioxidant enzyme activity and increased susceptibility to oxidative stress-related conditions.
Glutathione Metabolism: Glutathione (GSH) is a crucial intracellular antioxidant involved in detoxifying reactive oxygen species (ROS) and maintaining redox balance. Genetic variations in genes involved in glutathione synthesis, recycling, and metabolism, such as glutathione S-transferases (GSTs) and glutathione reductase (GSR), can influence individual differences in GSH levels and antioxidant capacity.
DNA Repair Mechanisms: Genetic variations in genes encoding DNA repair enzymes, such as base excision repair (BER), nucleotide excision repair (NER), and double-strand break repair (DSBR) pathways, can affect the efficiency of DNA damage repair in response to oxidative stress. Deficiencies in DNA repair capacity due to genetic polymorphisms may increase susceptibility to DNA damage accumulation and genomic instability associated with oxidative stress.
Inflammatory Pathways: Genetic variations in genes encoding inflammatory cytokines, receptors, and signaling molecules can influence the inflammatory response to oxidative stress. Dysregulated inflammatory signaling pathways due to genetic factors may exacerbate oxidative stress-induced tissue damage and contribute to chronic inflammatory conditions.
Metabolic Pathways: Genetic variations in genes involved in metabolism, energy production, and mitochondrial function can impact cellular redox balance and susceptibility to oxidative stress. For example, polymorphisms in genes related to glucose metabolism, lipid metabolism, and mitochondrial electron transport chain components may affect ROS production and antioxidant defense mechanisms.

Overall, genetic factors can play a significant role in determining individual differences in oxidative stress susceptibility, antioxidant capacity, and response to environmental stressors. Understanding the interplay between genetics, lifestyle factors, and oxidative stress can provide insights into personalized approaches for mitigating oxidative damage and promoting overall health and longevity.

Excess exercise can contribute to oxidative stress through several mechanisms:

Increased Oxygen Consumption: During intense or prolonged exercise, the body’s oxygen consumption increases significantly to meet the elevated metabolic demands of working muscles. This elevated oxygen consumption can lead to the production of reactive oxygen species (ROS) as natural byproducts of cellular respiration.
Muscle Damage: High-intensity or prolonged exercise can cause mechanical stress and microtrauma to muscle fibers, leading to inflammation and oxidative stress as the body works to repair the damaged tissues. The inflammatory response triggered by exercise can further increase ROS production.
Energy Production Pathways: In conditions of high energy demand, such as during intense exercise, there can be an increase in electron leakage from the electron transport chain in mitochondria. This electron leakage can result in the production of superoxide radicals, contributing to oxidative stress.
Activation of Immune Response: Intense exercise can also stimulate the release of pro-inflammatory cytokines and activation of immune cells in response to tissue damage and inflammation. While inflammation is a natural part of the body’s healing process, it can also generate ROS as a byproduct of immune cell activity, contributing to oxidative stress.
Decreased Antioxidant Defenses: Excessive or prolonged exercise may deplete the body’s antioxidant defenses due to increased ROS production and oxidative damage. Antioxidants such as vitamins C and E, glutathione, and enzymes like superoxide dismutase and catalase play a crucial role in neutralizing ROS and protecting cells from oxidative damage. However, during periods of intense exercise, the demand for antioxidants may exceed the body’s ability to produce or replenish them, leading to oxidative stress.

Overall, while regular moderate exercise is associated with numerous health benefits, including improved cardiovascular health, metabolism, and mental well-being, excessive or intense exercise without adequate recovery may increase oxidative stress and potentially contribute to tissue damage, inflammation, and impaired performance. Proper training regimens, adequate rest and recovery, and a balanced diet rich in antioxidants can help mitigate the effects of oxidative stress associated with exercise.

In summary, how do we improve our health now for our future self?

As we age, the health of our mitochondria becomes increasingly important for overall health and vitality. Mitochondria are often referred to as the “powerhouses” of our cells because they are responsible for producing the majority of our cellular energy in the form of adenosine triphosphate (ATP). However, mitochondria are also susceptible to oxidative damage, which can impair their function and contribute to age-related decline.

Oxidative Stress: Mitochondria are a major source of reactive oxygen species (ROS) production in the cell. While ROS play important roles in cell signaling and metabolism, excessive ROS production can overwhelm the antioxidant defense systems and lead to oxidative damage to mitochondrial components, including lipids, proteins, and DNA. This oxidative damage can impair mitochondrial function, disrupt energy production, and contribute to cellular dysfunction and aging.
Polyphenols and Antioxidants: Polyphenols found in foods such as fruits, vegetables, tea, and wine have been shown to possess potent antioxidant properties. These compounds can scavenge free radicals, reduce oxidative stress, and protect mitochondria from damage. By neutralizing ROS and enhancing antioxidant defense mechanisms, polyphenols and other antioxidants can help maintain mitochondrial health and function as we age.
Gut Health: Emerging research suggests that gut health may also play a crucial role in mitochondrial function and overall aging. The gut microbiota produce metabolites such as short-chain fatty acids (SCFAs) and secondary bile acids, which can influence mitochondrial metabolism and energy production. Additionally, gut dysbiosis and increased intestinal permeability (leaky gut) can lead to systemic inflammation and oxidative stress, which can negatively impact mitochondrial function and contribute to aging-related pathologies.

In summary, oxidative stress, polyphenols, antioxidants, and gut health are interconnected factors that can influence the health of our mitochondria as we age. By reducing oxidative stress, supporting antioxidant defense mechanisms, and promoting gut health through a balanced diet rich in polyphenols, fiber, and beneficial gut bacteria, we can help preserve mitochondrial function and promote healthy aging. Additionally, lifestyle factors such as regular exercise, adequate sleep, and stress management can also play important roles in maintaining mitochondrial health and overall well-being throughout the aging process.

Sirtuin Activation: NAD+ is a co-substrate for sirtuins, a family of proteins involved in regulating various cellular processes, including metabolism, stress response, and longevity. Sirtuins require NAD+ for their enzymatic activity, and activation of sirtuins has been associated with healthspan extension and lifespan regulation in animal studies.

Age-Related Decline: NAD+ levels tend to decline with age, which may contribute to mitochondrial dysfunction, impaired energy metabolism, and age-related diseases. Supplementing with NAD+ precursors like nicotinamide riboside (NR) or nicotinamide mononucleotide (NMN) has been proposed as a strategy to replenish NAD+ levels and support mitochondrial function and healthy aging.

NAC and NAD+ are two compounds that may help support mitochondrial function and promote healthy aging through their antioxidant, anti-inflammatory, and metabolic regulatory properties. By reducing oxidative stress, enhancing mitochondrial biogenesis, and supporting cellular energy metabolism, NAC and NAD+ supplementation have the potential to mitigate age-related decline in mitochondrial function and contribute to overall healthspan extension. However, more research is needed to fully elucidate the mechanisms underlying their effects on aging and longevity in humans.

By integrating these components into a comprehensive longevity health optimization protocol, individuals can support metabolic health, preserve muscle mass and function, and promote overall well-being and longevity. It’s important to adopt a sustainable approach that emphasizes consistency, balance, and individualized strategies tailored to unique needs and preferences. Regular monitoring of key health markers, such as blood glucose, lipid profiles, body composition, and physical performance, can also provide valuable feedback and guide adjustments to optimize health outcomes over time.
