Selenium and Glutathione Peroxidase: Battling Reactive Oxygen Species

It is thought that reactive oxygen species (ROS) are involved in many disease states to include arthritis, cancer, cardiovascular disease, diabetes, and Alzheimer’s disease (Duthie, 2003; Stockler-Pintos, Mafra, Farage, Boaventura, & Cozzolino, 2010). As such, maintaining optimal levels of anti-oxidants are critical in managing the destructive nature of ROS. Glutathione peroxidase (GSH-PX) is an example […]

Antioxidants and Cell Health

Antioxidants are substrates, which serve to protect a cell’s DNA, lipid membranes, and proteins from reactive oxygen species (ROS) (Duthie, 2003). As such, optimal levels of antioxidants are paramount in maintaining an organism’s health, performance, and longevity. Furthermore, ensuring that said substrate is adequately recycled for continued use is equal relevance (Gropper, Smith, & Carr, […]

Mitochondria and Cardiac Health: Exploring the Connection

The heart is a muscle (cardiac muscle) critical to sustaining life and homeostasis. Such an organ serves as a pump, which propels blood towards the lungs and other tissues via associated vasculature (Reisner & Reisner, 2017). Cardiac muscle is designed to work in almost near perpetuity; other muscles (i.e., skeletal) are not always required to […]

CoQ10, Optimizing Absorption, and Statin-Related Deficiencies

CoQ10 is a nutrient whose production tends to become down-regulated by two main sources: genetic mutations involved in its synthesis (a primary deficiency) and statins, which inhibit an enzyme (hydroxymethylglutaryl coenzyme A) involved in the development of CoQ10 (considered a secondary deficiency) (Potgieter, Pretorius, & Pepper, 2013). Secondary deficiency is a common side-affect amongst individuals on […]

Multiple Sclerosis, Neurological Support, and Vitamin D3

Multiple sclerosis (MS) is a disease characterized by inflammatory, demyelinating, and autoimmune events affecting more than 2 million people worldwide (Reich, Lucchinetti, & Calabresi, 2018).Brum, Comini-Frota, Vasconcelos, and Dias-Tosta (2014) stated that although the etiology of multiple sclerosis (MS) has not been clearly uncovered, there does exist environmental and genetic factors thought to manifest the […]

Determining Optimal Vitamin D Levels

Optimal vitamin D levels, as measured by 25-hydroxyvitamin D, remains to be somewhat equivocal, thereby affecting recommended oral doses of vitamin D3. Since research indicates the critical relationship of vitamin D to optimal health, it behooves one to consider the nuances and implications of recommending supplemental vitamin D to individuals. The following will explore the […]

Vitamin D3 Production

Vitamin D3, also known as cholecalciferol, is the precursor/pre-vitamin to 1,25-(OH)2D; the active form within the body, known as calcitriol (Chaplin & Jablonski, 2013). Vitamin D3 can be derived from sun exposure as well as foods such as fatty fish (i.e., salmon and sardines), plants (i.e., shitake mushrooms), fortified foods (i.e., milk, yogurt, butter, cheese) […]

Vitamin A Deficiency: Signs and Symptoms

In less developed countries, vitamin A deficiency (in conjunction to protein, iron, and iodine deficiency) are the leading causes of child deaths worldwide (Vijayaraghavan, 2000). Early signs of said deficiency can express itself as xerophthalmia (dryness of eyes), nyctalopia (night blindness), and dry skin (Gropper, Smith, & Carr, 2018). Although such signs can prompt one […]

Crohn’s Disease and Vitamin A

CD is characterized by chronic intestinal inflammation, followed by periodic intervals of remission (Soares-Mota et al., 2015). Part of controlling said inflammation is through lowering the concentration of reactive oxygen species (ROS) along the gastrointestinal tract. Such a process is known to reduce tissue damage associated with CD. Furthermore, as part of a complex of […]

Vitamin E and Oxidation

Vitamin E is a fat-soluble compound along with A, D, and K. Said vitamin is most widely recognized by its anti-oxidant capabilities and capacity to maintain and protect cell membranes and lipoproteins (Gropper, Smith, & Carr, 2018). As a means of appreciating vitamin E’s role as an anti-oxidant, the following will briefly consider its structure, […]
