Vitamin Drinks Risk Serious Harm

Are Vitamin Drinks a Bad Idea?

I need time to write about so many exciting things I am seeing in my practice, but this is always lurking. Children and athletes are at most risk for growing toxicity from overdosing on supplements. This has yet to be studied. Not just from vitamin drinks but daily vitamins pills too.

.

IV Infusion clinics are the rage now popping up all over London. The very luxurious price alone would convince most people that the more they pay, the better it feels. Did it begin in Hollywood? Surely La Jolla will be soon.

.

I see so much of the excess. My thoughts are often on the harm of vitamins and supplements and I’ve posted here, here, here, here, here, here, here, here, here, here about their risk to brain, peripheral nerves, heart, hypertension, cancer, interference with chemotherapy and cardiovascular medications, and in some cases risk to every cell of the entire body.

$18 Billion a year business in the U.S

.

This is an $18 billion a year business in the U.S. which explains why, since the 1970’s, Congress shot down the FDA’s authority to regulate dietary supplements and nutrients that could be fortified. Of course, congress restricts and excludes trade of European supplements that have proven scientific value. Usually this would be called unfair trade, but ….

.

Forgive me for being superfluous to point out that those who bring in one bottle with 30 ingredients astonishes me. Centrum Silver I’m thinking of you. How much titanium, molybdenum, chromium and zinc do we need every day to go with its toxic doses of B6 and the proven harmful Vitamins A and E? What is so completely lacking in the diet? How easy is this on seniors with reduced capacity to metabolize medications? No studies, thanks.

.

I favor several important vitamins for key reasons based on blood work, but known essential supplements seem to lost on many. Zinc is everywhere. This is rarely tested in a patient. Who has ever once tested most things in Centrum Silver? Could the popularity be due to bombardment or with unproven labeling or endless aisles of bottles?

.

This is a rich person’s game.Typically female, unless guys are hiding or avoiding them.

.

There are those who drag behind them truck loads of large suitcases bursting with expensive supplements. They need to stop the cause of their problems that is in those bags. They may link bags together with cabling like a train or walk back several times to pull in more and more.

.

Stop all of them. That is the treatment. That and a long, long drug holiday to wash them out of the system. Eat a basic healthy diet in moderation and always exercise. There is then hope to re-establish equilibrium. Who could swallow that many pills every day and have any room left for food?

But I digress.

Risks

46 novel beverages tested

.

“there is little evidence that consumers stand to benefit

from the micronutrients most commonly found in these products.”

.

But aiyee!!! the problems.

.

At long last, after billions spent on vitamin drinks, the risks are addressed by Valerie Tarasuk, lead author of the study. She is nutrition science professor at the University of Toronto faculty of medicine. I quote extensively from the New York Times but recommend the entire article.

.

“A nationwide study carried out by the National Institutes of Health in 2012 found that Americans who take vitamins and supplements were already getting large amounts of nutrients from their food, and on top of that they had the lowest prevalence of vitamin deficiencies to begin with. The study found that supplement use put these people at increased risk of potentially excessive consumption of folic acid, calcium, iron, zinc, magnesium and vitamins A, C and B6.”

.

 “…for much of the general population today, there is no scientific justification for a high intake of vitamins and minerals, said Mara Z. Vitolins, a registered dietitian and professor of epidemiology and prevention at Wake Forest Baptist Medical Center.”

.

“When consumed in excess, some water-soluble vitamins like B and C are excreted in the urine [unless toxic to nerves and kidneys, those of you who develop nerve pain and kidney stones from them]. But fat soluble-vitamins – including A, D, E and K – accumulate in tissues, posing potential risks.”

.

“These fat soluble vitamins are very stable,” she said. “They’re not released in the urine. If you are over-consuming them, you can raise your levels gradually over time and get into trouble with liver function. You have to be very careful with them.”

.

Authors should warn be even more cautious when you lose weight, the fat and that giant stash must somehow get out or what harm will they all cause next?

.

“Data from clinical trials have highlighted clear risks from excess. A large study published in JAMA in 2009, for example, looked at clinical trial data on more than 6,000 heart disease patients who were treated daily with either B vitamins or placebo over a seven year period. The study found that those who were given folic acid and B12 had higher mortality and cancer rates.”

.

“In 2012, a review of 78 clinical trials involving 300,000 people that was published in the Cochrane Database found that antioxidant supplements like beta carotene, vitamin A and vitamin E actually increased mortality. A year later, the United States Preventive Services Task Force concluded that there was “limited evidence” that taking vitamins and minerals could prevent cancer and cardiovascular disease.”

.

“The task force noted that two clinical trials had found “small, borderline” reductions in cancer incidence in men who took multivitamins. But the group also said there was good evidence that high doses of antioxidants could cause harm.”

.

No one could ever be funded to study the untold combinations of a single bottle that contains 30 ingredients. Studies require placing humans at risk long term, not a quick look at test tubes or a few mice.

.

The majority who have finances for these products are often among the best fed in the world if not the the most prosperous.

.

If you have read this far, you are not the person lumbering to push these truckloads of supplements ahead like Sisyphus.

.

Know hope.

.

That readers will read.

.

Is there any hope with congress?

.

Do not overlook the A, B, C’s

.

.

Balancing the harms, the staggering 90% less atrophy has been shown in areas typically harmed by Alzheimers in the OPTIMA study (Oxford Project to Investigate Memory and Ageing) at Oxford University, March 2013, when they looked at persons with mild cognitive impairment (MCI).

.

They looked at brain MRI changes in 156 volunteers before and after two years after placebo vs certain doses of B vitamins. No one has tested these doses long term for toxicity. I would never recommend their dose of B6 that has known toxicity to brain and peripheral nerves, see my post here. And they hold a patent on this vitamin regimen, making the protocol potentially suspect.

.

It has been shown a few years before, that size of the hippocampus tends to predict Alzheimers to some extent.

 

.

We know that those with Major Depressive Disorder and those with chronic low back pain have been shown to develop brain atrophy and memory loss. It would seem essential to test these vitamins again on those groups and replicate the study on mild cognitive impairment, with placebo controlled double blind testing. Again, caution, B6 can be toxic.

Ketamine for Intractable Pain: 5-Year Study of Efficacy & Safety, A Retrospective


.

.

Efficacy and safety of oral ketamine for the relief of intractable chronic pain: A retrospective 5-year study of 51 patients
European Journal of Pain, 11/25/2014

.

Marchetti F, et al. – This work summarizes the efficiency, failures and adverse effects of oral administration of ketamine at home for intractable pain. Pain was reduced or abolished in two–thirds of patients under ketamine therapy; ketamine was effective for patients taking opioids and resulted in few adverse effects.

.

Methods

.

  • This 5–year retrospective study involved testing ketamine by intravenous in–hospital administration, then a conversion to an oral route, or oral treatment directly administered at home.

  • The daily intravenous dose was increased by steps of 0.5 mg/kg to attain an effective daily dose of 1.5–3.0 mg/kg.

  • Pain was evaluated on a numeric scale from 0 to 10, and evidence of adverse effects was collected every day.

  • The effective daily dose was delivered orally (three to four intakes).

  • If effective, ketamine was continued for 3 months.

  • Short infusions or direct oral treatment began with a 0.5–mg/kg dose, then the daily ketamine dose was increased in 15– to 20–mg increments.

    .

Results

.

  • Among 55 cases (51 patients, neuropathic pain 60%), the mean effective oral dose was 2 mg/kg.

  • Ketamine was effective in 24 patients (44%, mean pain reduction 67±17%), partially effective in 20% (mean pain reduction 30±11%), with a mean opioid sparing of 63±32%, and failure in 22%.

  • Half of the patients experienced adverse effects, but only eight had to stop treatment.

  • For patients with opioid therapy, failure of ketamine was less frequent (7% vs. 36%; p<0.02), with fewer adverse effects (33% vs. 68%; p<0.01).

CurcuVIVA reduces joint pain, helps Alzheimers – Oxycodone use much lower


.

.

Rheumatoid arthritis pain is much better in a 54 year old female. She had half the month’s supply of oxycodone left at end of month for breakthrough pain – a big surprise! She had begun CurcuVIVA one daily for that month. It is a dietary supplement available without prescription.

.

PJ’s Prescription Shoppe carries it to make it easier for patients though it is available elsewhere.

.

CurcuVIVA is a capsule taken once daily. You will see the name Longvida on its label and in the literature. It is the same thing.

.

It is curcumin, the active ingredient in turmeric. It differs from turmeric because this form does cross the blood brain barrier to reach brain. Turmeric does not reach the brain, therefore turmeric has no effect on Alzheimers Disease or tauopathies (accumulation of tau proteins). Tau in Alzheimers Disease and frontotemporal dementia and parkinsonism has been linked to chromosome 17.

.

UCLA Alzheimers research unit developed this form of curcumin under the direction of Sally A. Frautschy and Greg Cole. On December 2012 they published in the Journal of Biological Chemistry showing Curcumin corrects molecular, synaptic and behavioral deficits in aged human tau transgenic mice.

 .

For more information on other actions of curcumin such as pain, etc, see a detailed review on the website of Memorial Sloan Kettering Cancer Center Herbs and Botanicals. I link to them on my website (bottom right column) as it is difficult to find. Curcumin has antiplatelet properties that may increase risk of bleeding. I recommend reading the details of mechanism of action and drug interactions.

.

Do not combine with other over-the-counter pain medications without checking this link for interactions.

.

It “exhibits neuroprotective, choleretic, anti-inflammatory, immunomodulatory, anti-proliferative and chemopreventive effects.” It was “found to be safe and equally effective as a non-steroidal anti-inflammatory drug for the treatment of osteoarthritis of the knee.”

.

Caution: “Patients with gastrointestinal disorders or predisposed to kidney stone formation should…use this supplement with caution.”

.

Contraindications: “Patients with bile duct obstruction, gallstones, and GI disorders including stomach ulcers and hyperacidity disorders should not take this supplement.”

Vitamin B6 toxic effects – sensory & motor neuropathies, some not reversible


.
.

HIGH DOSES GONE WILD

.

TOXICITY OF B6

.
.

So many of us fail to study the supplements that we take, and trust our bodies to inadequately trained people trying to sell vitamins. It’s a multi-billion dollar business.

.

In my first posts on this site April 2009, I warned about several vitamins that can be toxic. Yet I see so many people who are taking harmful doses. Many have harmful cardiovascular effects, as I posted later after publication by a colleague at Mayo Clinic.

.

Vitamin B6 is almost always found in high doses in “energy” drinks and in higher and higher doses in vitamins. I have seen patients taking 11,000 times higher dose than the recommended daily allowance, the RDA.

.

Eleven thousand times higher dose.

.

Eleven thousand.

.

No wonder they are barely able to move due to nerve pain from scalp to toe. So severe they cannot tolerate anyone touching the skin. And they are seeking opioids? to relieve pain?

.

.

Vitamin B6 can cause severe nerve pain and much worse. Damage may not be reversible, but if it is, it may take more than one year.

.

Less is more.

.

The information on Vitamin B6 toxicity below is directly quoted from Memorial Sloan Kettering Cancer Center Herbs and Botanicals website. Refer to their page for references and much longer discussion of benefits that I have omitted.

.

.

From Memorial Sloan Kettering Cancer Center

Herbs and Botanicals website

.

High B6 intakes can have toxic effects including sensory and motor neuropathies, and some case reports of neurotoxicity have not been reversible (29). B6 levels can also be elevated due to environmental exposures or genetic defects (1).

.

At the same time, because PLP is the metabolically active form of B6, it is thought to be responsible in instances of vitamin B6 toxicity (29). High circulating pyridoxine levels may have direct toxic effects on peripheral sensory ganglia neurons in the lower blood–nerve barrier, whereas the blood–brain barrier protects neurons in those regions from higher levels (35). The negative impact of B6 upon levels of other B vitamins appears to be dose-dependent and occur with chronic exposure (29).

.
Warnings

.

Long-term intake of high doses vitamin B6 can lead to nerve problems (29).

.

Adverse Reactions
.

High concentrations of vitamin B6 may result in severe peripheral sensory neuropathies and ataxia. Toxicities have reversed following discontinuation in some instances (37), but some case reports of neurotoxicity have not been reversible (29).

.
Case reports

Irreversible sensory ataxia in octogenarians: Three elderly patients in their eighties presented with sensory ataxia (lack of voluntary coordination of muscle movements) and signs of polyneuropathy (damage or disease affecting peripheral nerves) for 3–8 months. Pyridoxine 600 mg daily was consumed for 3–10 years in a B1-6-12-combination tablet. B6 blood levels were markedly elevated at 66–104x ULN. After 2 years of vitamin discontinuation, the patients showed no significant improvement in either neuropathy or gait, and no other likely cause for neuropathy in these patients could be identified (29).

.

Severe sensorimotor neuropathy: Due to B6 hypervitaminosis in a 75-year-old white man, accompanied by yellowish-brown skin pigmentation. Discontinuation of B6 led to improvement 1 year later, when he no longer used a wheelchair and could walk without a cane. Skin color also resolved, but ataxic signs were still present (38).

.

Herb-Drug Interactions
.

Altretamine: Pyridoxine may diminish its therapeutic effect (39).
Oral contraceptives: May moderately increase pyridoxine requirements (40).
Levodopa: Enhances levodopa metabolism, thereby reducing its effects (41) (42).
Penicillamine: May increase the requirements for pyridoxine (32).
Seizure medications (phenytoin, phenobarbital): High-dose pyridoxine may decrease serum concentrations (43).
