The Coronavirus 2019 (Covid-19) pandemic has affected people all over the world. It is caused by Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2). In December 2019, the virus was initially identified in the Chinese city of Wuhan, and it quickly spread around the world. Fever, significant asthenia, and a dry cough are common symptoms, which can escalate to more serious presentations such as deadly acute respiratory disease syndrome (ARDS).

The majority of infected patients suffer from mild to moderate respiratory infection and recover without the need for specific treatment. Some persons who are infected have serious illnesses and require medical intervention. Old aged people are at high risk for covid-19 infection. Pneumonia, myocarditis, ARDS, and inflammation in which the body responds quickly to invaders, destroying its own immune cells, influence the severity of Covid-19.

People with underlying medical disorders such as diabetes, cardiovascular disease, lung disease, or cancer are more prone to experience serious illness.1 Apart from all these medical conditions, in a recent genomics-guided tracing of the Covid-19 targets in humans, vitamin D supplementation was found as one of the top-scoring substances suggesting probable infection reducing patterns.

Vitamin D Supplementation Reduces Acute Respiratory Disease Syndrome (Ards) In Lungs:

Angiotensin-converting enzyme 2 (ACE2) is a membrane protein expressed particularly in lung cells. It helps the body from inflammatory damages. In contrast, coronavirus binds to ACE2 receptors to gain entry in a cell. This process causes downregulation of ACE2 and helps coronavirus to invade the cells and causes severe respiratory illness.2

The effect of Vitamin D supplementation towards respiratory illness has shown good response. A study carried out on mice with chronic ARDS showed that administration of Vitamin D has decreased the symptoms of the illness. It was seen that Vitamin D on administration showed increased expression of ACE2 and thereby moderating the chronic symptoms.3

Vitamin D Has Anti-inflammatory Effects:

The activation of the immune system's inflammatory pathways is required for a normal antiviral immune response. When immune cells come into contact with pathogens, they create cytokines also known as pro-inflammatory cytokines which are secretory proteins. These cytokines aid in the removal of infectious particles, decreasing injury. If this immune system's response is abnormal, it can cause severe disease if left unchecked.4

Vitamin D supplementation (800-1000 IU) has been shown to have anti-inflammatory properties in addition to its role in calcium metabolism. The effects of vitamin D on a highly triggered immunological response were investigated in a study. Vitamin D has been discovered to decrease cytokine synthesis in immune cells. Vitamin D activity may be crucial in preventing Covid-19 infection, as patients with severe Covid-19 sickness have been found to have Vitamin D deficiencies. The severity of Covid-19 infection rises due to immune cells' aggressive secretion of pro-inflammatory cytokines in response to infection. This implies that vitamin D supplementation may assist patients cope with the cytokine storm that is common in Covid-19 infection.5

Vitamin D Has Antiviral Activity:

Vitamin D is necessary for proper local immune responses to respiratory viral infections. Vitamin D generated by lung epithelium could lead to increased expression of antimicrobial peptides (such as cathelicidin and defensin in adjacent immune cells). There is evidence that cathelicidin has antiviral activity against influenza A virus and respiratory syncytial virus infections (RSV) by binding to virus, which leads to disruption of the virus envelope.6 This direct antiviral activity of Vitamin D may be helpful against enveloped viruses like Coronavirus.

Vitamin D Stabilize Physical Barriers On Human Cell:

Physical barriers are made up of tightly packed cells that keep invaders (such as viruses) from reaching organs which are infection-prone. Tight junctions, gap junctions, and adherens junctions are examples of these barriers. Vitamin D has been shown to help to the stability of all of these junctions, despite viruses affecting their integrity and invading the tissue (physical barriers).7

Based on these findings, a COVID-19 randomised control trial has compared the effect of high-dose vitamin D against conventional dose on 14-day mortality in COVID-19 older patients. In rescue patients with severe Vitamin D deficiency, high-dose oral vitamin D3 treatment has been proven to reduce short-term mortality. Oral vitamin D supplementation at dosages up to 10,000 IU/day for short periods of time is regarded as safe, especially in older persons, who are most affected by Vitamin D deficiency and should receive at least 1,500 IU of vitamin D daily to maintain adequate vitamin D status.8

The ability of people's skin to manufacture vitamin D3 reduces as they age, leaving them more susceptible to vitamin D3 deficiency. This could explain why elderly people are at such a high risk of contracting COVID-19. Vitamin D deficiency, as well as other medical conditions including diabetes, high blood pressure, and cardiovascular disease, can all be considered risk factors for the severity of COVID-19. Considering the lack of a particular treatment for COVID-19 and the safety of vitamin D supplementation9, these findings would support the use of vitamin D supplements as a COVID-19 adjacent treatment.

Why Is iThrive Essential’s Vitamin D3 Supplement Better & Effective Than All Other Otc Supplements?

iTHRIVE Essential’s vitamin D3 capsules contain vitamin K2 and the synergistic link between the two vitamins is critical. According to recent studies, vitamin K2 aids in the absorption of calcium provided by vitamin D3 in the bones without enabling calcium to build up in the arteries.10 Pure medium-chain triglycerides (MCT) oil derived from coconut oil is also included. It's a type of fat that our bodies can easily absorb and convert to energy. MCT has also been shown to increase the amount of energy consumed by your muscles.11 It can aid in the production of ketones, a carb-free energy source for the brain. MCT can also be used to cure and relieve skin infections. MCT contains lauric acid, which acts as an antibacterial, destroying bacteria and viruses by breaking down their walls.12 The iTHRIVE Essential’s Vitamin D3 capsule is liquid-filled which is launched for the first time in the Indian market. These capsules absorb more quickly than ordinary powder-filled tablets, allowing them to act more quickly. The coating of a liquid-filled capsule may be broken down and absorbed into the bloodstream in a matter of minutes, but a powder-filled capsule can take 20-30 minutes as tablet medicines must first be entirely broken down. For this reason, liquid-filled capsules are generally considered to be faster-acting. iTHRIVE Essential’s Vitamin D3 is created with the intention of providing all of the benefits required.

The human body works like a domino effect. If one domino falls, they all fall. This concept is a little lost in today’s world, where people have normalised various health issues due to their rampancy. We see every other person suffering from bloating, acne, lethargy, weak immune system and a wave of such symptoms. These dysfunctions indicate things going off in the body on a cellular level. It is important to fix them, lest one may also suffer in the long-term.

Despite multiple health interventions, most people are stuck with guesswork for their symptoms with basic blood tests. But advanced tests are here to the rescue, giving us a deep dive into the root cause of underlying dysfunctions! In today’s world, gastrointestinal and autoimmune disorders are on the rise. As a healthcare practitioner it is inevitable to be aware of the best tests available to heal your clients, and more importantly how to choose between them.

This is a four-part blog series: In the first part we cover GI-MAP by Diagnostic Solutions and Array 12 by Cyrex. The rest of the series will cover the Functional Genome Analysis test, OMX and the Dutch Plus hormone panel.

Magnifying the gut with GI-MAP

We know that troubles with the gut can give rise to a lot of dysfunctions through the gut’s connection with the brain, immune system, metabolism, thyroid, skin, hormones, heart, and bone! There are trillions of microbes - good and bad - living in our gut that play a vital role in our overall health. This is called the gut microbiome. The gene set of these microbes is 150 times greater than that of the human genome! Analysing this ecosystem with advanced tests like GI-MAP (Gastrointestinal Microbial Assay Plus) has become quite popular today.

GI-MAP gives us invaluable insight into the DNA of the microbes living in the gut. It uses advanced qPCR (quantitative polymerase chain reaction) technology to amplify specific regions of the DNA present in a stool sample — it can detect even the smallest amounts of genetic material.

Some conditions that warrant testing are autoimmune diseases, IBS (Irritable bowel syndrome), digestive complaints, IBD (irritable bowel disease), brain fog, skin problems like acne and psoriasis, depression, anxiety, diabetes, weight loss issues, and hormone imbalance. Since the health of your gut plays a key role in every organ system and practically every disease condition, this test is a potentially useful tool for almost all cases.

How is GI-MAP different from other gut tests?

It amplifies and detects pathogens that are often missed in techniques like culturing and microscopy.
Since it uses quantitative PCR, it not only identifies the presence of microbes but also gives a precise measure of their abundance: How high or low the population of a pathogen is and whether it needs to be treated.
The quantitative analysis helps to assess the severity of an infection or imbalance in the gut microbiome.
It can also test for antibiotic resistance by analysing the genes of pathogenic bacteria in your gut.

GI-Map assesses the following:

GI-MAP looks for various pathogenic bacteria, parasites, viruses and worms wreaking havoc in your gut.
It also looks at friendly bacteria like commensal bacteria that extract nutrients and energy from our diets, maintain gut barrier function, produce vitamins like biotin and vitamin K, and protect against colonization by potential pathogens.
It gives us an idea of the general health of the gut microflora and measures the levels of good bacteria against the bad.
It assesses fungi/yeast in the gut that may be culprits for dandruff, joint pains and itchy scalp. It also looks for non-pathogenic parasites that don’t cause diseases but lead to issues like gas and bloating.
It can benefit people with autoimmune diseases as some pathogens are associated with autoimmune conditions.
It is also a good measure of gallbladder health and checks if the stomach is secreting enough gastric juices. It has markers that indicate pancreatic functions and the amount of fat present in stools.
The gut controls 70-80% of our immunity so the test can tell us where one’s immunity lies on a spectrum.
It detects your gut’s reaction to gluten.
It can be used to test for leaky gut if the optional zonulin marker is included.

Keep in mind that the results of GI-MAP reflect the different strains of pathogens carrying toxic genes, not the level of toxins that may be produced by them. A practitioner has to couple the findings from the test with the patient’s health, volatile nature of some pathogens and the expression of virulence factors in the form of symptoms.

The Array 12 - Pathogen-Associated Immune Reactivity Screening from Cyrex Laboratories

A lot of factors influence the human microbiome such as genetic makeup, diet, environmental stressors, stress, sleep and activity. Often, your immune system can get overwhelmed with excess environmental stressors like heavy metals, chemicals and drugs. This can create an imbalance in your gut microbiome and make it a breeding ground for pathogens, infections and colonisation by non-beneficial bacteria, viruses, yeasts and parasites.

While trying to restore the balance, your immune system may start attacking its own cells, tissues and organs that have been contaminated – this might progress to autoimmunity.

Decode your dysfunctions with Array 12

Array 12 by Cyrex can help assess the presence of these pathogens triggering autoimmunity. Array 12 analyses the immune load from 29 viral, bacterial, fungal, parasitic and stealth pathogens that may be dormant in the body. It uses blood samples to look for IgG (Immunoglobulin G) antibodies against pathogens that show immune reactivity long after exposure.

For example, it can detect gingivitis bacteria that contribute to tooth decay, penicillium used in antibiotics, acinetobacter that plays a role in multiple sclerosis due to cross-reactivity with neurological tissues, not-so-well-known pathogens such as borrelia bacteria from ticks that cause lupus.

If interventions such as detoxification, diet and lifestyle changes are not working then this test can be used to dig deeper. Array 12 is recommended for patients with chronic conditions such as gastrointestinal distress, fatigue, body aches, unexplained inflammation and neuroinflammation.

GI-MAP v/s Cyrex Array tests

Most autoimmune conditions are idiopathic, that means their causes are unknown and can only be deciphered to a certain extent. So, advanced tests like GI-MAP and Array are your best bet.

While Array 12 is useful to trace existing pathogens causing auto-immune diseases, GI-MAP can go the extra mile to spot infections that could potentially develop into auto-immune conditions in the future. It must be clear till now that GI-MAP is much more detailed, however here are some cases where Array 12 may be more useful than GI-MAP:

GI-MAP may miss out on infections that have passed on from the gut to other organs in the body, this is where Array 12 can be helpful. For instance, in cases where Candida is too extreme it might not show up in the gut and be traceable in other organs.
Array 12 is helpful to spot Epstein-Barr virus (EBV) and tick-borne diseases that GI-MAP may miss out on because they are found in the blood and not in the stool.
In addition to positive and negative ranges, Array 12 also shows equivocal ranges to detect infections that may have existed in the body in the past.

However, if we really have to choose then GI-MAP is the most elaborate advanced test available. Even for people with autoimmune conditions, we recommend that they first go for GI-MAP and get a comprehensive snapshot of their gut. Array 12 can complement GI-MAP to probe further into the autoimmune condition.

People also often compare GI-MAP with Array 2 by Cyrex for gut issues. If one wants a detailed analysis of the gut then GI-MAP is the way to go. Whereas Array 2 can be used as a complementary test to check the integrity of the intestinal barrier and gut permeability, food sensitivities and allergies.

The results from advanced tests are helpful to get to the bottom of dysfunctions. It is important that you sign up with a good functional medicine practitioner to get an accurate interpretation of your results. So, if your disease has taken over your life, get going with these advanced tests and target your health issues with utmost precision!

The natural and predominant components of the gut microbiota are different species of bacteria. Among the many intestinal microbes, those thought to have the ability to improve the host's health by altering the intestinal microbiota are frequently chosen as probiotics.

Probiotics are living organisms that provide health benefits when consumed in adequate amounts. These organisms are naturally present in fermented and dairy products. The two most common probiotics are Lactobacillus and Bifidobacterium ¹. Probiotics are used to boost the immune system, prevent gastrointestinal illnesses, modulate the effect of hypocholesterolemia, and promote oral and dermal health. Probiotics may also be used to help with sadness and anxiety ².

These bacteria provide various health benefits, such as preventing bowel diseases, improving the immune system, maintaining intestinal microbial balance, reducing traveler’s diarrhea, etc. Initially, probiotics were marketed in the form of fermented foods and dairy products. In recent years, probiotics are now available from non-dairy sources because lactose intolerance has increased ³.

Non-dairy probiotic products consist of patented probiotic formulations in the form of a powder that contains the strains, i.e., the subclasses of Lactobacillus, Bifidobacterium, and other probiotic strains. Bacteria produce spores to defend themselves from harsh conditions like temperature, salinity, acidity, etc. Spore-based probiotics are unique in that they can survive the acidic conditions of the gut while still performing their intended functions.

Spore-based probiotic strains:

Endotoxins are the compounds present in the blood as a result of eating foods with high fat and calorie contents. that can stimulate inflammatory action in the body. It stimulates the inflammatory reaction in the body. It can cause intestinal inflammation and damage cell-to-cell connections in the intestine. Increased serum endotoxins are the hallmark of the condition known as endotoxemia (presence of endotoxins in the blood). Studies on spore-based oral probiotics show that they are crucial in lowering intestinal permeability, in which cell-to-cell connection in the gut is lost ⁴. Several studies have suggested that Bacillus clausii may be a safe and effective treatment option for acute infantile diarrhoea ⁵.

Similarly, B. coagulans LBSC proved effective in reducing the pathophysiological symptoms of IBS overall while remaining safe for human ingestion ⁶.

Lactobacilli strains:

In human therapeutic trials, Lactobacilli strains including Lactobacillus plantarum and Lactobacillus rhamnosus have been used to improve immunological function, treat intestinal problems, and lower the risk of cardiovascular disease. According to scientific evidence, it may be able to protect kids from developing acute gastroenteritis (AGE), antibiotic- or healthcare-associated diarrhoea (AAD and HAD, respectively), and other conditions ⁷. It has been demonstrated that Lactobacillus gasseri strain LG21 improves Helicobacter pylori eradication and lessens adverse antibiotic effects. A promising mouse pilot study revealed that Lactobacillus gasseri OLL2716 suppressed the growth of antibiotic-resistant H. pylori and decreased inflammatory cytokines ⁸. It will take more study to confirm the clinical applicability of this discovery.

Bifidobacterium strains:

Due to the related health advantages, bifidobacteria have been used commercially as probiotic agents. Bifidobacterium species, such as Bifidobacterium breve, Bifidobacterium longum, Bifidobacterium bifidum, etc., have been shown to play a significant role in the prevention or treatment of ulcerative colitis, diarrhoea, inflammatory bowel disorders (IBD), etc ⁹.

Yeast:

A yeast called Saccharomyces boulardii is used as a probiotic because it works well to cure bacterially-induced diarrhoea. According to a meta-analysis of research, S. boulardii is protective against diarrhoea brought on by antibiotic use, Clostridium difficile infection, enteral nutrition-related diarrhoea, traveler's diarrhoea, and Helicobacter pylori infection. Irritable bowel syndrome (IBS), Crohn's disease, ulcerative colitis, and other chronic disorders have all been evaluated for using S. boulardii ¹⁰. Numerous S. thermophilus species have demonstrated that it has immunomodulatory effects and a variety of anti-inflammatory immune-modulatory capabilities ¹¹.

With the current major research advancements, there is no question that the application of probiotics for human health will increase.

According to estimates, 50% of people worldwide have low vitamin D levels, with the highest prevalence among adults over 60, those with a dark complexion, and those who are obese (1).

Vitamin D deficiency has also been linked in recent studies to psychological conditions like sadness, anxiety and seasonal affective disorder. It has also been suggested that low levels of Vitamin D may be linked to depressive symptoms. It is so since it functions as a steroid in many brain processes, such as neuroprotection, regulation of neurotrophic factors, neuroplasticity, brain development, and neuroimmunomodulation (3). The correlation, not the causation, between the two conditions, maybe because many individuals at risk for depression are also at risk for vitamin D deficiency.

Depression can cause various symptoms, including decreased productivity, trouble concentrating, irritability, weariness, appetite loss, low self-esteem, feelings of worthlessness, suicidal thoughts, and changes in body weight (4).

Not all, but some cross-sectional clinical and epidemiologic studies have discovered a substantial correlation between low Vitamin D levels and greater levels of depressive symptoms or a depression diagnosis. There is evidence that patients with depression have low Vitamin D levels. The relationship between the brain's 1-alpha-hydroxylase enzymes and Vitamin D receptors may indicate that Vitamin D plays a specific role in the central nervous system (5).

SEASONAL DEPRESSION AND VITAMIN D

Sunlight is the main source of vitamin D, which is why it is sometimes known as the ‘sunshine vitamin’ (2).

Climate and weather fluctuations are linked to seasonal depression. Changes in solar exposure affect the body's vital hormone levels, including serotonin and melatonin. The level of serotonin depends on the availability of Vitamin D, which is required for synthesising the hormone. As a result, as exposure to sunshine declines, so do Vitamin D levels and, subsequently, serotonin levels. This signifies the relationship between Vitamin D and seasonal depression (6).

Vitamin D can also be obtained from various dietary sources like red meat, liver, egg yolks, and oily fish like sardines, mackerel, and salmon.

Contrary to popular belief, When people say sunlight provides vitamin D, they are actually talking about the UV rays you receive from the sunlight. Our skin naturally contains a precursor to vitamin D. When exposed to UV rays, the precursor is transformed into a molecule called vitamin D3 (7).

Vitamin D's fundamental function is maintaining proper amounts of calcium and phosphorus for several metabolic processes, regulating bone and muscular strength, healthy immune system operation, and neuroprotection (8). People with depression receive relatively little sunlight because they spend most of their time indoors.

To meet your body's Vitamin D needs, spend at least 10-15 minutes outside three days a week (9).

RECOMMENDED DOSAGE OF VITAMIN D

The recommended daily allowance (RDA) for individuals is 600 IU of Vitamin D, increasing intake to 800 IU for those over 70. Studies have shown that Vitamin D supplements up to 2000 IU significantly reduce depression in pregnant women (10). According to the National Institutes of Health, it is safe to take up to 4000 IU of Vitamin D for depression (8).

Check your Vitamin D levels if any of these depression-like symptoms apply to you. Your doctor will do a test to find out how much of the Vitamin is in your blood. Getting in touch with a reputable healthcare provider if you're displaying signs of depression is crucial. Fortunately, it's simple to obtain Vitamin D by either taking supplements, getting more sunlight, or including foods high in Vitamin D in your diet.
