False Labeling of Supplements

Alock2020 profile image

I suggested to my neurologist that instead of taking Gabapentin and Quetiapine for anxiety, that I try various supplements (such as Ashwagandha, Chamomile Extract, Hops, Lavender, Rhodiola, etc.) instead, since there may be short- and long-term side effects from taking the two drugs.

She said that supplements are not regulated in the U.S., that the supplements industry is rife with fraud, that many of the pills contain very small amounts of what the labels claim that they contain, and that they often contain other substances which are either ineffective or even harmful.

Any opinions on this?

Medical doctors are propagandized to believe that prescription medications can do no harm and supplements can do no good. Unfortunately many of them buy into it. I am a subscriber to Consumer Lab which tests supplements. The vast majority of supplements have exactly what they say they have. The places were fraud is rife are from the fly-by-night suppliers for diet, muscle building, and sexual enhancement pills. Another place I have found fraud is rife is essential oils, unfortunately. Vitamins and other substances from major suppliers are trustworthy.

Edit - also, FDA does regulate supplements. See my comment below.

Labdoor is another decent one.

My opinion is that your doctor gave you good advice.

Depends if you want advice from Medical professionals or medical amateurs.

Try Lithium Orotate. I gave it to my mother who is PwP for years. 5mg of Li element (from 125-130mg of Lithium Orotate) are sufficient and no detectable in the blood test, unlike Lithium Carbonate or Citrate. Before she took it she was agitated and depressed and now she is in good mental health.

I have foind that LO does the same for me, much more relaxed and calm.

Neither Gabapentin nor Quetiapine are exactly good for anxiety, they are both one of those dangerous antipsychotics perhaps to use only upon failure of just about everything else, in a case of significant intractable anxiety, not just your "run of the mill" anxiety, even if chronic. They both work against dopamine and really you should look it up and research it all by your own self on the internet before venturing into that land.

Kind of like taking a surgical grade scalpel to trim a nail cuticle. One tiny little slip and...

In addition if I recall gabapentin was more of an anti-spasmodic, to control and prevent siezures, and for idiopathic nerve pain from various neuropathies...like when you feel like your literal "wires are being fried, frazzled, electrified," "shocky".

On the other hand, there may be much that you are not telling us and are leaving out.

For anxiety there are many reasonable supplements, as well as better prescription alternatives than antipsychotics...excepting of course the general problem with supplements in that there are no regulations and no enforcement as to quality, truth in labels, freedom from adulteration, or any real reliable assurances as to safety and effectiveness.

FDA does regulate supplements. From the FDA website:


• " Manufacturers and distributors of dietary supplements and dietary ingredients are prohibited from marketing products that are adulterated or misbranded. That means that these firms are responsible for evaluating the safety and labeling of their products before marketing to ensure that they meet all the requirements of DSHEA and FDA regulations.

• FDA is responsible for taking action against any adulterated or misbranded dietary supplement product after it reaches the market."

Good morning ~ an intensive care nurse told me that doctors get a kickback at the end of the year from pharm companies for the amount of prescriptions they write. Made sense: I went to my doctor to get a referral to PT for stress knots in my neck. He refused. Would only write me a prescription for ibuprofen, which I had in my cabinet! At the next open enrollment, I switched Drs snd my plan

That’s one reason they only prefer pharmaceuticals. The other reason comes from my 2 Dr brother in laws: in Med School, they have, maybe, 1 2-hour class on nutrition

They just are not informed

Good morning 🌞 yes, my statement was too broad. My Dr is “integrative:” he practices both, and prefers high quality supplements whenever possible. The search was lengthy to find him. There are some.

And I would add: it is true. Nutritional supplements are not regulated. The inexpensive brands, like the big box stores or brands from pharmacies, are not good. I would recommend as above: join consumer reports that test & report.

Your neurologist is protecting her business model. You don't need her help to heal yourself.

I think that you should ask her for recent proof of her claims regarding the supplements you inquired about. If she can't provide it, then I think you will have the answer you are looking for.

Here are the side effects for Gabapentin, one of the drugs she would like to give you and keep in mind that the reason you wanted help was for anxiety, which is a known side effect of Gabapentin ! Next ask her about withdrawal symptoms from Quetiapine .

You might ask your doctor if she is aware of these many side effects that Gabapentin has caused and then ask her if she is sure she still wants you to take it! There is a problem when the side effects can be worse than what you are trying to treat!

Your thoughts on Passion Flower vs Melatonin?

chartist profile image
chartist in reply to Despe

Hi Despe,

Passion flower falls into a group of plants that have shown benefit for sleep, relaxation, anxiety, stress and to help induce calmness. I have only tried it for sleep and I tried a non extract form which had no noticeable benefit for me. If I were to try it again, I would use the extract form, but right now, melatonin is working for sleep again.

Passion flower is said to have other positive health effects but quality human studies are lacking and a search of PubMed turns up 935 studies whereas melatonin turns up over 28,000 studies and quite a few human studies that have shown positive results. I am likely biased when it comes to melatonin because so many studies have shown its health benefits and it is produced throughout the body as are melatonin receptors clearly showing that the body knows how to use melatonin and clearly has many uses for it. Melatonin is produced in the mitochondria throughout the body to help maintain and protect mitochondrial health. Mitochondria that are perturbed produce significant amounts of damaging ROS as is seen in many disease states and ill health including PD. Melatonin is the most potent antioxidant in the body through both direct and indirect effects

When you search PubMed for mitochondria and passion flower, you get two irrelevant results. My opinion is that comparing melatonin and passion flower is like comparing apples and oranges. They both have the potential for good health effects, but are not really comparable due to each having vastly different mechanisms of action.

Despe in reply to chartist

Art, thanks! You are absolutely right about Melatonin, but it's not about sleep, it's rather about anxiety and stress.

My sister's young MD asked her to take Passion Flower for anxiety and stress, as she's been very stressful the last few days due to continuous STRONG earthquakes. That made me think that Passion Flower can help with anxiety and stress my husband experiences. His sleep has so much improved with the addition of Megnesium Glysinate to his Melatonin, it's amazing.

Since human studies are scarce for PF, we are mainly relegated to peoples reviews and sleep, anxiety and stress relief are three that are often mentioned in PF reviews.

Regarding magnesium glycinate and melatonin for sleep.... 😫😫😫😫😫! Yes they are a good combination and healthful. The combo mag pill of mag-T, magnesium glycinate and magnesium taurate is also good. Kia recommended that one as useful for sleep. The study I wrote about used magnesium, melatonin and zinc to good effect for sleep. These are all healthful and non addictive and they help many sleep and reduce nocturia!

Despe in reply to chartist

Thanks, Art. All that you mentioned are on my husband's menu (except Mg Taurate). :) Indeed, the nocturia is not there anymore, unbelievable!

My pleasure, Art!

I would like to ask you if one takes all three forms of B3 would that be harmful? Thank you.

"There is a problem when the side effects can be worse than what you are trying to treat!" AMEN!

It reads like a TV commercial where the narrator tells you the possible side effects in 10 seconds - who would ever take these drugs if they were fully informed?!


I'd like to add to Art's comment on Gabapentin.

My mother got TIAs from quiatapin. I found out through my own genetic testing that quiatapin is contraindicated for me. Doctors don't screen for this.

First, do no harm and exercise the precautionary principal.

I buy high quality supplements and read labels. I avoid combination supplements with unnecessary additives and buy single ingredients to make my own blend. I can't swallow pills anymore and pulling capsules open is a 🫓 (pita), this way I can put it in juice or a smoothie, some are by injection or intranasal. Lots of ways to get them where they need to go.

Point well made.

It blows me away that a doctor would use as the rationale for prescribing gabapentin because supplements are not as well-regulated.

All supplements like all doctors are not created equal.

I've always been amazed how many pharmaceuticals have a dramatic effect on unrelated processes in the body. I mean, here is a drug that can cause a myriad of ear problems or kill you if you have epilepsy. I don't see the connection between the 2.

It seems to me an enormous imbalance in the ongoing debate on this forum as to whether or not supplements are effective and the consequences of (what are most often nonessential prescription of) pharmaceuticals.

In other words, there is a big difference between being ineffective & being dead.

....and he's back!

Now that is the Marc I know and remember!!!

Marc, if any supplement had a list of side effects like Gabapentin does, it would be banned by the FDA in a New York minute, but Gabapentin is regularly prescribed and has been for over 25 years, it's that simple!


Is she saying that the drug industry is not rife with fraud? Well, any sane person knows differently. For instance if Congress didn't protect the vaccine industry from all liability they would have been out of business a long time ago. Yes, you have to do your best to find quality supplements and avoid products from China. But as you will soon realize just about everything we own comes from China. Which is one of many reasons we are where we are in America today. We have shipped all our jobs overseas. Natural supplements usually are safe and come with no lasting side effects if any. I always try to get organic supplements that have little if any added ingredients. We use organic orotate lithium in small amounts 5 mg. once in morn and once at night for anxiety and have recently added Organic India Ashwagandha for good sleep and energy. If you have a side effect from any supplement, just stop taking it and the side effect will go away. Unfortunately it doesn't always work that way with drugs.


Doctors get most of their treatment information from pharmaceutical companies, according to Robert Yoho, MD, in his book Butchered by “Healthcare.”

At this writing (September 2021), the book is available for free download at robertyohoauthor.com/

Very eye-opening, especially the chapter on mental health drugs.

A lot of input on Gabapentin but is it true for Lyrica as well? I would welcome some input on OTC treatement for neuropathy. I was on Gabapentin up to over 2.7 gms a day. I was switched to Lyrica an now up to the max recommended for this drug. Any one have suggestions for neuropathy OTC RX??? Are there any other OTC supplements used off label like prescriptions for treatement for Global neuropathy, I am also plagued with Parkinson's.
