Coming off benzodiazepines is, frankly, a nightmare for many. It’s not just about willpower. It’s a physiological overhaul. When you’ve been on a drug like Xanax, Valium, or Ativan for a while, your brain’s GABA receptors basically go on strike. They’ve forgotten how to work without the chemical assistance. So, when you start that slow slide down the dosage scale—the taper—your central nervous system starts firing like a short-circuited fuse box.
People get desperate. I’ve seen it in every forum from Benzobuddies to Reddit. You’re shaking, you haven’t slept in three days, and your anxiety is a physical weight on your chest. Naturally, you look for a magic pill to fix the pill problem. You start searching for supplements to take during benzo taper because you want the edge taken off. But here’s the kicker: the wrong supplement can actually set you back months. It’s a minefield. Some things help, some do nothing, and some—like certain herbs that hit the same receptors—can actually trigger a "kindling" effect that makes withdrawal even more brutal.
We need to talk about what’s actually happening in your brain and which specific nutrients might actually lend a hand without making the situation worse.
The GABA-Glutamate See-Saw
Your brain thrives on balance. Specifically, the balance between GABA (the "brakes") and Glutamate (the "gas"). Benzos are massive GABA enhancers. Over time, your brain compensates for this extra braking power by cranking up the glutamate and toning down its own GABA production.
When you taper, the "brakes" are removed, but the "gas" is still floored.
This is why you feel "wired and tired." Your brain is literally over-excited. The goal of using supplements to take during benzo taper isn't to replace the benzo. You can’t do that. The goal is to gently support the nervous system while it slowly relearns how to regulate itself.
Magnesium: The Heavy Hitter
If there is one supplement that almost everyone in the withdrawal community agrees on, it’s magnesium. But even this is complicated. Magnesium is a natural NMDA receptor antagonist. In plain English, it helps dampen that "screaming" glutamate activity I just mentioned. It’s like putting a little bit of insulation on a bare wire.
A study published in Gene found that magnesium deficiency can actually mimic anxiety disorders. When you’re under the extreme stress of a taper, your body dumps magnesium like it’s going out of style. You’re likely depleted.
However, don't just grab the cheapest bottle at the drugstore. Magnesium Oxide is basically a laxative; it’s not going to help your brain. You want Magnesium Glycinate or Magnesium L-Threonate. The glycinate version is bound to glycine, an amino acid that itself has a calming effect on the brain. Threonate is the "fancy" one that supposedly crosses the blood-brain barrier more effectively. Some people swear by it; others find it too stimulating.

Try a small dose first. Start low. Your CNS is sensitive right now. Honestly, even a warm bath with Epsom salts (Magnesium Sulfate) is a great way to get it through your skin without upsetting your stomach.
The Vitamin B Complexity
This is where things get dicey. You’ll see "B-Complex" on every list of health supplements, but for someone in benzo withdrawal, B vitamins can be a double-edged sword.
B6, for instance, is a necessary cofactor for the production of GABA. Sounds great, right? Well, B6 is also a cofactor for the production of dopamine and norepinephrine—the "alertness" chemicals. For some people, a high-dose B-complex feels like drinking ten cups of coffee. It can spike "toxic" anxiety.
If you’re going to look at B vitamins, maybe focus on B12 (methylcobalamin) if you're deficient, but be cautious. Many veterans of the Ashton Manual method—the gold standard for tapering developed by Dr. Heather Ashton—suggest avoiding high-dose B vitamins until the nervous system has stabilized. If you’re already vibrating, you don't need more "energy."
L-Theanine: A Gentle Nudge
You find this stuff in green tea. L-theanine is an amino acid that promotes "alpha" brain waves—the kind you have when you’re relaxed but alert. It doesn’t hit the GABA-A receptor directly in the way a benzo does, which is why it’s generally considered "safe" for a taper.
It’s subtle. It won't stop a panic attack in its tracks, but it can take the "sharpness" off the anxiety. A common dose is 200mg. Some people find it helps them sleep, while others use it during the day to stay functional. The beauty of L-theanine is that it’s rarely associated with a "crash" or dependency, though, as always, your mileage may vary.
The Melatonin Debate for Insomnia
Sleep is the first thing to go. It’s brutal.
Melatonin is the hormone your brain produces to tell you it’s nighttime. During a benzo taper, your circadian rhythm is usually a mess. Taking 1mg to 3mg of melatonin can help some people find a rhythm.

Don't go overboard. More is not better with melatonin. High doses can cause vivid nightmares, and when you're already dealing with "benzo dreams"—which are already basically feature-length horror movies—you don't want to add fuel to that fire. Keep it low. 1mg is often plenty.
The Danger Zone: Supplements to Avoid
This is actually more important than what you should take. There are several supplements to take during benzo taper that people mistakenly think are helpful but are actually dangerous or counterproductive.
- Kava Kava: This is a big one. Kava is a potent GABAergic. It feels like a benzo. Because it hits the same receptors, it can prevent your brain from healing. You’re basically just substituting one "crutch" for another, and it can cause a "wave" of withdrawal symptoms when it wears off.
- Phenibut: Stay away. Just stay away. Phenibut is a powerful GABA-B agonist. The withdrawal from Phenibut is often described as being even worse than benzos. Adding this to a taper is like trying to put out a fire with gasoline.
- Valerian Root: It’s a weak GABA modulator. While some people tolerate it, others find it triggers a "revved up" feeling or a "rebound" effect.
- High-dose Vitamin C: Some people find it stimulating. It can also speed up the metabolism of certain medications, potentially messing with the steady blood levels you need for a smooth taper.
Amino Acids: NAC and Taurine
N-Acetyl Cysteine (NAC) is gaining a lot of traction in the psychiatric world. It’s an antioxidant that helps regulate glutamate. Since glutamate excess is the primary driver of withdrawal symptoms, NAC can be a godsend for the "brain fog" and the intrusive thoughts that often plague a taper.
Taurine is another amino acid that acts as a mild GABA agonist and help stabilize cell membranes. It’s often found in energy drinks (ironically), but on its own, it’s quite calming. Many in the tapering community find it helps with heart palpitations.
Probiotics and the Gut-Brain Axis
We often forget that about 90% of our serotonin and a significant portion of our GABA are influenced by our gut bacteria. A benzo taper usually wreaks havoc on the digestive system—commonly called "benzo belly."
Taking a high-quality probiotic or eating fermented foods (if you can tolerate the histamines) can help. A study in Biological Psychiatry suggested that specific strains like Lactobacillus helveticus and Bifidobacterium longum can actually reduce cortisol levels and anxiety. If your gut is happy, your brain has a much better chance of staying calm.
Fish Oil and Inflammation
Chronic stress causes neuroinflammation. Your brain is literally "inflamed" during withdrawal. High-quality Omega-3 fatty acids (EPA and DHA) are essential for nerve repair.
You want a brand that is molecularly distilled to remove heavy metals. Look for a high EPA-to-DHA ratio. It won't give you immediate relief, but it provides the raw materials your brain needs to rebuild those damaged receptors over the long haul. It’s a marathon, not a sprint.

Practical Strategy for Success
You cannot supplement your way out of a bad taper plan. If you are dropping your dose too fast, no amount of magnesium will save you. You need to follow a slow, hyperbolic taper—reducing by no more than 5% to 10% of your current dose every few weeks.
When introducing supplements to take during benzo taper, follow the "Rule of One."
- Introduce only one new supplement at a time.
- Wait 3 to 5 days to see how your body reacts.
- If you feel worse, stop immediately.
- If you feel okay, you can try adding the next one.
If you start five things at once and have a bad reaction, you won't know which one caused it. Your nervous system is hypersensitive right now. Treat it like a frightened animal.
Real Talk on Expectations
Supplements are tools, not cures. They might reduce the severity of your symptoms by 10% or 20%. That might not sound like much, but when you’re in the thick of it, 20% is the difference between being able to go to the grocery store and being trapped in your bedroom.
Be wary of "withdrawal support" blends sold online. They often contain 20+ ingredients, including things like 5-HTP or Ashwagandha, which can be extremely polarizing. Some people love Ashwagandha for cortisol control; others find it causes "anhedonia" or a total loss of emotion. Stick to single ingredients so you have total control.
Listen to your body. If you take something and your "tinnitus" (ringing in the ears) gets louder or your "zaps" get worse, your body is telling you it's not ready for that supplement.
Actionable Steps for Your Taper
- Audit your current cabinet: Toss anything expired or known to be a GABA-stimulant like Kava or Phenibut.
- Start with Magnesium Glycinate: Take it in the evening. It’s the safest starting point for most people.
- Track everything: Keep a simple log. "Tuesday: Added 100mg L-Theanine. Felt slightly calmer, no change in sleep."
- Focus on hydration: Supplements need water to process. Withdrawal is dehydrating.
- Consult a professional: Find a doctor or a pharmacist who understands the "Ashton Method." Most standard MDs aren't well-versed in the nuances of supplement interactions during a taper.
- Prioritize whole foods: Before you spend $200 on pills, make sure you're eating enough protein and healthy fats. Your brain is made of fat and runs on amino acids.
The road to healing is slow. It’s frustrating. But your brain is plastic. It can heal. These supplements are just the scaffolding to help you stay upright while the building is being repaired.
