Do Vitamins Help During Benzodiazepine Tapering and Withdrawal?

Do vitamins help with benzodiazepine withdrawal?

Do vitamins help a person get through a benzodiazepine taper? It is one of the first questions patients bring to Dr. Leeds, often with a bottle already in the cabinet. For most people who eat normally, the honest answer is no, and the reason is worth knowing before the next bottle is bought.

The question comes up because withdrawal feels like something is missing. A person who has taken alprazolam (Xanax), clonazepam (Klonopin) or lorazepam (Ativan) as prescribed for years, and who now feels exhausted, foggy and shaky as the dose comes down, is not a person with an addiction. That person has physical dependence, a predictable adaptation of the nervous system to a medication a doctor prescribed, and dependence is not addiction.

In 2020 the United States Food and Drug Administration (FDA) put dependence and withdrawal into the boxed warning on every benzodiazepine label, a late admission that these symptoms are the drug’s doing. Dependence is treated by tapering the medication slowly, over months and sometimes longer, at a pace the patient can tolerate. Nothing sold in the vitamin aisle does that job.

The Ashton Manual says there is no general need for extra vitamins.

Professor C. Heather Ashton answered this question directly in the Ashton Manual, in the Chapter III section on diet, fluids and exercise. Her advice was plain: “There is no general need for dietary supplements or extra vitamins or minerals,” all of these “can be harmful in excess,” and “in general stick to a normal healthy diet without food fads.” The Manual is free to read at benzo.org.uk.

She returned to the subject in the 2011 Supplement, in its section on nutritional supplements, and the position sharpened rather than softened. There is no evidence that vitamins, minerals or amino acids help in benzodiazepine withdrawal, and no evidence that withdrawal causes vitamin, mineral or other deficiencies. Excessive doses of some supplements are toxic, and some products contain benzodiazepine-like substances with the same adverse effects as the drug itself.

Professor Ashton’s rule was that “no-one should take supplements without clear evidence of a specific deficiency.” Dr. Leeds starts from the same place and then decides patient by patient, because some supplements cause trouble in withdrawal and others help a particular person. A normal diet already contains everything most bodies need, and blood work, not marketing, decides whether anything is missing.

Why does withdrawal feel like a vitamin deficiency?

Benzodiazepines work by enhancing gamma-aminobutyric acid (GABA), the brain’s main calming signal. Over years of daily use the receptors that respond to GABA adapt, and the calming system comes to depend on the drug. Each dose reduction leaves that signal weaker than the nervous system expects, until the receptors readjust.

A nervous system short on calming signal produces fatigue, muscle weakness and aching, tingling, poor concentration, low mood and broken sleep. Those are also the textbook symptoms of low iron, B12, vitamin D or magnesium. So, the patient concludes that something must be depleted. Unfortunately, the internet is glad to agree.

A car’s dashboard is a fair picture of it: in withdrawal the gauges read empty, but the tank is usually full. The drug altered the gauges, and they settle only as the receptors settle. Pouring in more fuel does not fix a gauge, so the sensible move is to check the tank once, with a blood test where there is reason to, and otherwise give the gauges time.

The taper, not the supplement, is what relieves the symptoms.

Fortunately, what eases withdrawal is a slow, steady taper that never gets ahead of the nervous system. For some patients that means a crossover taper to diazepam, as the Ashton Manual describes in Chapter II, because a long-acting drug smooths the blood level between doses.

For most it means reductions that get smaller as the dose gets lower, the hyperbolic shape the Maudsley Deprescribing Guidelines describe, so that each step feels about the same. The pace belongs to the patient, and if a reduction brings symptoms the patient cannot live with, the dose is held and the next reduction waits. That takes months, sometimes longer, and there is no product that shortens it.

Speed is the danger, not a missing vitamin. Stopping a benzodiazepine abruptly, or cutting too fast, can bring on severe symptoms, including seizures. Anyone who has a seizure or any other medical emergency should call emergency services at once.

Should a patient in a long taper have a B12 level checked?

Often, yes, and here the vitamin question has a real answer. Vitamin B12 deficiency causes fatigue, numbness or tingling in the hands and feet, unsteadiness, memory problems and mood changes, and every one of those overlaps with benzodiazepine withdrawal.

A B12 level is therefore a reasonable part of the workup for anyone whose taper will run for months, so that a treatable deficiency is not written off as withdrawal, or the reverse. Benzodiazepines are not known to block the absorption of B12, so the drug itself is not the reason to check; the overlap of symptoms is.

Yet, there is no such thing as “B12 withdrawal”: a person who is not deficient should not expect B12 to ease withdrawal, because the evidence is lacking and clinical experience does not support it. A person who is deficient is treated for the deficiency and usually feels some benefit. That is treatment of a second condition, not of withdrawal.

Does vitamin D help with withdrawal, and can it be taken with clonazepam?

Vitamin D deficiency is common regardless of medication, and a person in a long taper who stays indoors and sleeps poorly is a fair candidate for it. A single blood test, the 25-hydroxyvitamin D level, settles the question. Guessing does not.

Patients tapering clonazepam often ask whether vitamin D3 (cholecalciferol) is safe to take alongside it. There is no known interaction between vitamin D and clonazepam or any other benzodiazepine, so correcting a documented deficiency is reasonable.

Neither the drug labels nor the Ashton Manual describe benzodiazepines draining vitamin D or thinning bone. The fracture risk in the labels is a matter of sedation and falls, and vitamin D does not fix sedation.

What vitamin D will not do is treat withdrawal. The evidence that it eases anxiety, sleep or mood during a taper is limited, and clinical experience varies. The recommended dietary allowance for adults is 600 international units, rising to 800 after age seventy; anything well above that is a prescriber’s decision, because vitamin D accumulates and toxicity, with nausea, weakness, confusion and high blood calcium, is real.

Does vitamin C help with benzodiazepine withdrawal?

Vitamin C is a harmless dietary vitamin with no role in benzodiazepine withdrawal. A normal diet with some fruit and vegetables covers the recommended dietary allowance, about 75 milligrams for women and 90 for men, with smokers needing a little more. There is no evidence that taking extra eases withdrawal symptoms.

The megadoses that circulate online mostly cause diarrhea and cramps, which for many people begins above about 2,000 milligrams a day. That is the whole story of vitamin C in a taper. Nothing over the counter shortens one.

What about B vitamins, magnesium and vitamin E?

Patients also ask about B-complex tablets, magnesium and vitamin E, and the answer for each has the same shape: limited evidence, no general need, and a prescriber’s call when a specific reason exists. Many patients in the benzodiazepine community are wary of magnesium, which they understand to act on the GABA receptor, and of B and D vitamins, because of what they felt when they tried them.

That caution has merit without being universal; individual response varies. Magnesium is the most reasonable of the three when a level is low, and its main effect at higher doses is on the bowel. Vitamin E is fat-soluble, and high doses carry their own risks, which is why more is not safer.

Dr. Leeds keeps these as individual conversations. A patient with a poor diet, a bowel condition that limits absorption, or a blood result out of range has a reason to supplement, and that reason decides the amount. A patient with none of those has no reason, and the money is better spent on food.

Which products should a person in a taper be wary of?

The products to be wary of are anything marketed as calming, sleep-promoting or “GABA-boosting.” Professor Ashton warned in the 2011 Supplement that some such products contain benzodiazepine-like substances, and that taking GABA precursors does not raise GABA in the brain. A product that seems to work for anxiety during a taper deserves suspicion for that reason: it may be acting on the receptor the taper is trying to free.

Anything of that kind added mid-taper also muddies the picture; the prescriber cannot tell what a symptom means. The cleanest taper is one where the only thing changing is the benzodiazepine dose.

How Dr. Leeds handles the vitamin question.

In Dr. Leeds’ practice, the vitamin question is answered by evidence, not by the supplement aisle. Where the history calls for it, a blood test for B12 or vitamin D finds any real deficiency, which is then treated on its own terms. The taper itself is gradual, medically supervised and paced by the patient, with a crossover to diazepam along the lines of the Ashton Manual where it helps.

Informed consent runs the same way for a supplement as for the taper: risks first, then alternatives, an exit plan agreed at the outset, and the right to decline any step. Dr. Leeds’ practice is concierge, based in Fort Lauderdale and open to patients throughout Florida; anyone who wants a taper planned this way can Contact Dr. Leeds to begin.
