What are the benefits of IV vitamin and mineral treatment?

When you take an oral supplement, it goes through your stomach and into your small intestine, where it’s absorbed into your bloodstream. By comparison, vitamins and minerals delivered intravenously go immediately into your bloodstream, where they’re rapidly carried to cells throughout your body.

A second benefit of IV infusion is that you can receive a larger dose. Oral supplements encounter several problems that prevent the full dose from getting into your bloodstream. For example, low stomach acid, deficient digestive enzymes, and health conditions, like inflammatory bowel disease, can all reduce the absorption of nutrients.

Another significant roadblock is that your small intestine can only absorb a limited amount of nutrients at one time. You don’t need to worry about such limitations when you get IV vitamins and minerals.

What nutrients will I receive in my IV vitamin and mineral treatment?

The Myers cocktail is named after the doctor who created IV nutrient therapy. The Myers IV infusion is designed to promote overall health and wellness by providing magnesium, calcium, vitamin C, and B vitamins, including vitamin B12.

Some additional vitamin and mineral treatment options:

IV vitamin C

As one of your body’s most important antioxidants, vitamin C is often administered intravenously to help treat cancer, fibromyalgia, and infections. Using an IV infusion is essential because blood levels of vitamin C are tightly controlled and limited when it’s taken orally. This control is bypassed with an IV infusion, so you can receive a higher dose.

Intramuscular injection of vitamin B12

Your small intestine can only absorb a small amount of vitamin B12 at one time. With an intramuscular injection, you get a therapeutic dose of vitamin B12, which rapidly treats a deficiency.

What health benefits might I gain from IV vitamin and mineral treatment?

In addition to quickly treating a nutrient deficiency, IV infusions provide the extra vitamins and minerals you need when illness, chronic disease, injury, or intense athletic training demand extra nutritional support.

IV nutrients can be part of your treatment for a medical condition.
The Myers cocktail helps treat:

  • Acute asthma attacks
  • Migraines
  • Chronic fatigue syndrome
  • Fibromyalgia
  • Upper respiratory tract infections
  • Chronic sinusitis
  • Seasonal allergies

You might benefit from IV vitamin and mineral treatment.

What are the benefits of IV vitamin and mineral treatment?

Intravenous (IV) hydration rapidly replenishes fluids, delivering a boost in energy and restoring the balance your body needs to maintain optimal performance.  IV hydration is an effective solution that can be a stand-alone treatment to improve your well-being or complementary therapy to support your treatment plan.  

What causes dehydration?

Dehydration occurs when your body doesn’t have enough water, which happens because you don’t consume enough fluids, you lose an excessive amount of fluids or a combination of both.

Excessive sweating due to an intense athletic activity or being outside on a hot day commonly causes dehydration. You can also become dehydrated when your body eliminates more fluid than normal due to excessive vomiting or diarrhea, which are problems caused by many illnesses and chronic health conditions.

What symptoms develop when I’m dehydrated?

When you’re dehydrated, you feel thirsty, tired, dizzy, or lightheaded. You also urinate less often and your urine appears darker than normal. You may have a dry mouth or develop muscle cramps. As your dehydration worsens, you may become confused, have a fast heartbeat, or faint.  

What happens to my body when I’m dehydrated?

Every cell and system in your body feels the effect of dehydration, so these are only a few examples:

Cardiovascular health

The amount of fluid in your body influences your total blood volume, blood pressure, and heart rate. When you’re dehydrated, blood volume drops and your heart works harder to get enough oxygen-rich blood to your organs and tissues.

Muscle performance

During intense activities, you can lose 6-10% of your body weight due to fluid loss. Yet it only takes a 2% drop in body weight due to sweating to affect your endurance and cause muscle fatigue.

Cognitive ability

Your ability to concentrate declines when you’re mildly dehydrated and moderate dehydration affects short-term memory.

What are the benefits of IV hydration?

By the time you realize you’re dehydrated, oral consumption may not replenish your fluids fast enough. The speed of your rehydration is limited by the amount you can comfortably drink. Additionally, oral rehydration isn’t as effective if you have a gastrointestinal problem, such as vomiting.

IV hydration very effectively overcomes these barriers to rehydration by bypassing your gastrointestinal tract and delivering a saline solution into your bloodstream. This quickly and safely boosts body fluids and restores your energy.

Another important benefit of IV hydration is the improvement to your overall health by including electrolytes in your IV infusion. When you lose body fluids through sweating, diarrhea, or vomiting, vital electrolytes like potassium and sodium are also lost. The proper balance can be restored during IV hydration.


What is integrative medicine?

One of the key principles of integrative medicine is to treat each patient as a whole person. This means taking the time to learn how your emotional, mental, social, spiritual, and physical issues contribute to your health problems.

By learning about all the factors that contribute to your symptoms, and determining whether you have nutritional, biochemical, and hormonal imbalances, your practitioner can create a comprehensive treatment plan that solves each problem rather than simply treating a symptom.

For example, you can take over-the-counter medications to relieve a recurring headache. But if your headache is triggered by something in your diet, ongoing stress, or a chronic sinus infection, you’ll keep having headaches because pain relievers treat the symptom, not the real cause of the problem. With integrative medicine, all the underlying issues are treated.

Another key component of integrative medicine is the type of treatment you receive. An ideal practitioner combines the best of both worlds, offering conventional medical treatments together with alternative medicine. They choose the treatments from both fields that are best for each patient.

What is alternative medicine?

Alternative medicine embraces a broad range of treatments other than conventional therapies like prescription medications.

These are only a few examples of  alternative treatment options:

  • Change in diet (especially for food allergies)
  • Nutritional therapy
  • Intravenous (IV) nutrient infusion
  • Herbal medicine
  • Homeopathic treatments
  • Vitamin and mineral supplementation

Other types of alternative treatment include low dose naltrexone (LDN), a medication support for autoimmune disease and chronic pain.

What conditions are treated with integrative and alternative medicine?

Integrative and alternative medicine can treat virtually every type of health condition, including:

  • Chronic fatigue
  • Fibromyalgia
  • Hormone imbalance
  • Mold and yeast toxicity
  • Cancer recovery
  • Cardiovascular disease
  • Allergy disorders
  • Arthritis
  • Skin disease
  • Mental health disorders

Alternative medicine can be helpful for anti-aging.

 What is low-dose naltrexone (LDN)?

Naltrexone is a medication that’s used at a full dose to help patients overcome alcohol or opioid addictions. When it’s administered at a low dose, however, it has a different therapeutic effect.

LDN causes three responses in your body:

  • Increases levels of endorphins
  • Boosts your immune system
  • Reduces inflammation

Endorphins are naturally produced in your body, where they relieve pain, improve your mood, and reduce stress. LDN may be used to treat autoimmune illness, and has the potential to relieve chronic pain.



What is bio-identical hormone therapy?

Hormone replacement therapy (HRT) restores deficient hormones back to their normal level.  Some prefer to use natural bio-identical hormones for HRT because they have the same chemical structure as the hormones produced by your body.

It is important to have in-depth testing to determine the dose needed to bring your hormones back to a normal range, followed by use of bio-identical hormones that are individually compounded to meet your exact needs.

Bio-identical HRT is the optimal way to regain your health because these hormones are less likely to cause side effects compared to synthetic hormones. Actress Suzanne Somers was a long-time advocate for compounded bioidentical hormone therapy.

How are my hormone levels tested before I receive bio-identical hormone therapy?

Many men and women have symptoms that suggest hormone deficiencies, yet blood tests frequently show their hormone levels are in the normal range. However, it is important to recognize that urine testing of hormones and their breakdown products often reveal different results.

Over the last decade, laboratory diagnostics have repeatedly shown that a blood test can produce normal results, while the same person’s urine sample reveals low levels of hormones.  Blood and urine testing can determine the precise dose needed.

As long as you take bio-identical hormone therapy, you should have hormone testing and evaluation. It is important to monitor your hormone levels and adjust your treatment as needed to maintain optimal health.

:What type of bio-identical hormone therapy is available?

Numerous bio-identical hormones can be compounded and used to replace hormones that naturally decline as you get older. In women estrogen replacement is the best known and most common use of bio-identical hormone therapy.

Bio-identical estrogen relieves the full range of menopause symptoms, from hot flashes and mood swings to vaginal atrophy. It also prevents chronic diseases associated with low levels of estrogen, such as osteoporosis.

Estrogen isn’t the only hormone imbalance that occurs as you get older. Men may need someone to prescribe bio-identical hormone therapy to replace testosterone. Beginning around age 30, men’s testosterone decreases by up to 2% every year causing problems, such as low sex drive, erectile dysfunction, fatigue, and loss of muscle mass.

Natural thyroid treatment for patients with hypothyroidism:
Thyroid hormone can also be produced as a bio-identical hormone to restore thyroid function and boost your metabolism.


What is chelation therapy?

Your body is constantly exposed to toxic metals found in the air, water, land, and food, as plants and animals also absorb environmental toxins. As these toxic metals or heavy metals accumulate in tissues throughout your body, they cause damage and disease.

During chelation therapy, your practitioner intravenously administers a medication such as EDTA. Once EDTA enters your bloodstream, it binds with toxic metals and certain minerals and then carries them out of your body.

How does chelation provide cardiovascular treatment?

Chelation helps treat cardiovascular disease by eliminating the toxic metals that are associated with heart and vascular problems.   

A study published in The Lancet in March 2018 found that low-level lead exposure is linked with conditions, such as high blood pressure, hardening of the arteries, and coronary artery disease. Additionally, lead exposure increases the risk of premature death from cardiovascular disease.

Chelation therapy removes several toxic metals known to contribute to cardiovascular disease. Cadmium, which is found in tobacco, air, and food, increases your risk for coronary artery disease. Exposure to arsenic and copper is also associated with a higher chance of developing coronary artery disease.

Emerging studies suggest that like lead, it only takes a low level of exposure to cadmium, arsenic, and copper to put your health at risk.

Can cardiovascular treatment with chelation reduce future problems?

The National Institutes of Health sponsored a study — the Trial to Assess Chelation Therapy, or TACT — to test whether chelation therapy with EDTA and/or high-dose vitamin therapy might treat cardiovascular disease. The medical team recruited 1708 patients, all aged 50 or older, who had suffered a prior heart attack.

Some of the participants received 40 EDTA intravenous (IV) infusions over the course of 28 months. The first 30 infusions were administered weekly, while the last 10 were infused every two to eight weeks. All the study participants were then followed for five years.

The results of the study show that those receiving chelation had an 18% reduced risk of developing future cardiac events such as angina (chest pain), heart attacks, and strokes.

The patients who received chelation therapy combined with supplemental vitamins and minerals had even better results: Their risk of cardiovascular events was 26% less compared to those who received chelation without supplements.

The practitioner should evaluate every patient with cardiovascular disease to determine whether toxic metal treatment can be safely administered along with their other medications and heart treatments. 


What is chelation therapy?

Chelation is a medical treatment that eliminates toxic metals and unwanted minerals from your body. When you undergo chelation, your practitioner administers a medication, such as EDTA, using an intravenous infusion.

Once the medication is in your bloodstream, it binds with toxic metals, such as iron, lead, and mercury. After the metal binds with EDTA, it can’t cause injury or disease and it’s eliminated during urination.

What are toxic metals and how do they affect my health?

Lead, mercury, iron, aluminum, cadmium, and arsenic are some of the most common and dangerous toxic metals or heavy metals. These metals are used in industry, agriculture, technology, and medicine. As a result, they end up contaminating the water, air, and soil, subsequently finding their way into the foods you eat.

As you’re exposed to heavy metals, they accumulate in tissues inside your body. Eventually, they reach toxic levels that are harmful to your health. Heavy metal toxicity may damage your:

  • Lungs
  • Liver
  • Bones
  • Endocrine glands
  • Central nervous system
  • Cardiovascular system
  • Gastrointestinal system

Chelation therapy is an effective way to flush toxic metals from your body.

What symptoms develop due to heavy metal toxicity?

The symptoms often associated with heavy metal toxicity include:

  • Chronic fatigue
  • Anemia
  • Difficulty learning or remembering new information
  • Brain fog or trouble concentrating
  • Neurological disorders
  • Cognitive decline
  • Joint of muscle pain
  • Depression and anxiety

Some toxic metals can also cause autoimmune diseases.

Does chelation help cardiovascular disease?

EDTA helps eliminate substances that are known to contribute to cardiovascular disease, such as lead, cadmium, and calcium, which combines with cholesterol to form dangerous plaque in your blood vessels.  It is important to evalutate patients to determine if chelation treatment should be used together with their other cardiovascular treatment.

A study called the Trial to Assess Chelation Therapy (TACT) tested chelation therapy in adults over the age of 50 who had suffered a heart attack. The results showed that chelation therapy lowered the risk of subsequent cardiovascular events like heart attack, stroke, and angina (chest pain).

The study also revealed that combining chelation with vitamin and mineral therapy further improved the results. Patients who received nutrient supplements reduced cardiovascular events by 26% compared to those who didn’t take supplements.


What are toxic metals?

Toxic metals, also called heavy metals, are widely used in industry, agriculture, and technology development. They’re also used in various medical applications. As a result, they end up in the air, water, soil, and ultimately, they’re found in certain foods. Significant environmental contamination also occurs where metals are mined.

The most common toxic metals include:

  • Lead
  • Mercury
  • Arsenic
  • Cadmium
  • Chromium

It only takes a small amount of these metals to significantly damage your health. They’re also known or probable carcinogens.

What symptoms develop when I’m exposed to toxic metal?

The toxicity of a heavy metal depends on variable factors, like the amount in your body and your age, genetics, and nutritional status. Toxic metals can enter your body through your skin, by inhaling air or eating or drinking contaminated items.

You can develop toxic metal poisoning through sudden exposure to a large amount or from long-term exposure to a small amount. Once the metals are in your body, they accumulate in tissues where they can cause significant harm.

Some of the most common symptoms of toxic metal poisoning include:

  • Abdominal pain, nausea, vomiting, and diarrhea
  • Heart abnormalities, such as arrhythmias, cardiomyopathy, and atherosclerosis
  • Nervous system problems, such as pain, numbness, and tingling of your hands and feet
  • Kidney or liver damage
  • Lung irritation
  • Memory loss
  • Horizontal lines on your nails
  • Changes in behavior

Toxic metals can cause a miscarriage in pregnant women. Children who are exposed to toxic metals suffer malformed bones, growth retardation, and developmental disabilities.

What is toxic metal detoxification?

Once you’ve been exposed to toxic metals, there are three important steps to detoxification: Identifying which toxic metals are in your body, eliminating your exposure to the metal, and chelation therapy to remove the metal from your body.

Practitioners typically perform urine toxic element screening, which measures the type and amount of metals excreted in your urine, and  uses blood tests to check for levels of lead.  If you receive chelation for lead poisoning, your urine is collected for six to eight hours afterward and analyzed for lead content.

Chelation therapy is performed using an intravenous infusion of agents that bind with the toxic metals and then carry the metal out of your body. In addition to chelation therapy, you may wish to consider use of additional vitamin and mineral supplements or other alternative medicine options to promote your overall health.



Can a special lab test identify my food sensitivities?

One of the specialized tests available is the Alcat Test, which evaluates your reaction to over 450 substances. Your test results show exactly which foods you should avoid based on your sensitivities and which substances trigger inflammation in your body.

The details provided by the Alcat Test can help you adjust your diet, heal your body, and reduce the symptoms caused by gastrointestinal disorders, metabolic disorders, and inflammatory conditions.

What should I know about mycotoxins?

Mycotoxins are abundant in the environment, where they’re produced by molds and are commonly found in foods, such as cereals, nuts, and dried fruits. Exposure to mycotoxins causes a variety of health problems, including fungal sinusitis, peripheral neuropathy, asthma, chronic fatigue, immune deficiencies, and inflammatory bowel disease.

Patients with persistent, unexplained symptoms often don’t realize they may have been exposed to molds and mycotoxins. That’s when testing with the MycoTOX or Organic Acids Test may help.

The MycoTox uses a single urine sample to screen for 11 different mycotoxins and 40 species of mold. The Organic Acids Test also check for mycotoxins, as well as invasive yeast and candida overgrowth.

Can I get a special lab test for chemical toxins?

With the GPL-Tox Profile, it only takes one urine sample to learn whether your body contains toxic chemicals. The test checks for 172 chemicals, including those associated with mitochondrial disorders and many other proven toxins, such as phthalates, insecticides, and organophosphate pesticides.

is uWhat other special lab tests are available?

These are just two additional lab tests used to determine the underlying cause of your symptoms and create a personalized treatment plan:

Comprehensive stool analysis

Gastrointestinal problems are one of the most common problems affecting patients; they’re also one of the most difficult to diagnose without specific lab tests. This comprehensive stool analysis evaluates how well your digestive tract is working and detects the presence of pathogens.

Nagalase in serum and plasma

Nagalase is an enzyme that’s secreted by cancerous and virus-infected cells. This special lab test is used to monitor the effectiveness of treatments for cancer and viral infections, including HIV.


 FDA Seeks To Outlaw Compounded Hormones!! HELP NOW

The FDA claims that the NASEM report, which recommends restrictions on compounded hormone therapy, is “independent” and “comprehensive,” but a third-party analysis of the NASEM report shows it to be compromised by conflicts of interest, and bad science. The analysis shows that the agency exerted inappropriate influence and bias in almost every phase of the commissioned report, even recommending study committee appointees who had NO EXPERTISE in prescribing or compounding hormones.
