10 BEST Natural Beta Blockers for Anxiety

Beta Blockers are a group of drugs that prevent norepinephrine and adrenaline from binding with beta receptors on your nerves.  Generally, beta blockers are used in order to reduce heart rate, reduce blood pressure, and reduce anxiety.

However, many of these drugs require doctor’s prescriptions and can have adverse effects including diarrhea, stomach cramps, nausea, vomiting, blurred vision, and fatigue.

Fortunately, nature has provided many natural beta blockers that can prove exceptionally effective in combating anxiety and depression. The list below ranks the top 10 natural anti-anxiety supplements in order of proven effectiveness, however depending on YOUR own personal needs and biochemistry you may find products higher on the list more effective for you. Enjoy!

1. L-Theanine

L-Theanine is an uncommon amino acid found in tea that is very useful as a relaxer. Unlike other substances like alcohol, L-theanine has the unique function of being able to relax and decrease anxiety without sedating the individual. It is becoming increasingly popular to pair with caffeine, as it reduces the popular stimulant’s harsh effects (jitters & crash). L-Theanine is cheap, fast acting, and effective with little to no side effects, making it our favorite natural beta-blocking supplement.

A study conducted on 20 healthy male volunteers showed L-Theanine’s ability to boost alpha wave receptors, which are known to reduce anxiety and improve overall concentration. Read the full study here.

L-Theanine is usually taken in dosages between 100-200 mg and typically alongside caffeine.

L-Theanine has a unique synergistic effect with caffeine that heightens attention, focus, and cognition. Although you can find L-Theanine in teas, you likely won’t be able to get an adequate dose through tea alone.

2. Kava Extract

Kava has been drunk for centuries throughout the south pacific as an anxiety reducer. In recent years the effectiveness of kava has been shown to be almost as potent as pharmaceuticals. Kava has been shown to decrease anxiety, boost subjective well-being, decrease depression and improve sleep quality.

There are many forms of kava and many different ways to supplement your diet with it. There is only one active ingredient in kava called kavalactones and this percentage usually indicates the potency of the kava extract. Traditionally it is ingested as a drink that is brewed at a low concentration of kavalactones but it also comes in other forms such as LI 150, which can be 13-20 times more concentrated than the basic root extract. Another form is WS 1490 which is branded as laitan 50 and contains 70% kavalactones.

For an effective dose to combat anxiety and/or depression you will want around 250 mg of the active kavalactones. That means that for the bottle at left that comes in 250 mg capsules at 30% kavalactone concentration, you would need to take about 3 capsules/day in order to receive the proper effective dosage.

3. Ashwagandha

An effective dose of ashwagandha is between 300-500 mg although doses of even 6,000 mg can be ideal depending on the situation. Taking the herb once a day in the morning is ideal for the average consumer.

4. Inositol

Inositol is a very safe supplement to take even at extremely high doses. On the flip side, it usually requires high doses of inositol to have an anti-stress or anti-depressant effects.

A standard dose of inositol can range from 14-18g per day. That means with the 750 mg capsules you’ll have to take 20 capsules/day in order to get the proper effectiveness. That might seem like a pain and expensive but at only 10 cents a capsule it’s only $2/day and might be worth trying out.

Inositol has been shown to be very effective treating panic attacks, anxiety, depression, high blood pressure, weight and PCOS.

5. Fish Oil

Fish Oil is practically the solution to every ailment or deficiency so it’s no surprise that it’s also been found to be effective as a natural beta blocker. Omega-3 fish oil consists of two kinds of fatty acids (EPA and DHA) that are typically found in fish. The effects of fish oil increase brain activity and require days or even weeks of supplementation to be effective.

The average dose of fish oil can range tween 250 mg to 1 gram daily as recommended by the American Heart Association. Quick tip: In order to mask the “fish burp” you can take fish oils with meals.

Fish oil has been linked to lowering blood pressure, triglycerides, depression, anxiety, and a full host of other things and since it’s so cheap there’s not much to lose in trying it out.

Bacopa monnieri is particularly interesting because it is often used to improve cognition and it does so by reducing anxiety and allowing the brain to perform better. If you’re looking for decreased anxiety, this supplement might bring you some added perks.

The standard dose of Bacopa is about 165 mg of active bacosides. So depending on the percentage of active ingredients you may need to take 1 to two capsules accordingly. NutriGold has about 100 mg of active bacosides per capsule so you may choose to take 2 capsules/day.

7. 5-HTP

5-HTP is a precursor to the neurotransmitter, serotonin, which is mostly responsible for mood, appetite and sleep. Supplementing with 5-HTP directly correlates with increased serotonin production for increased happiness and reduced depression in those lacking serotonin.

In addition to improving anxiety and depression, 5-HTP has been shown to decrease appetite and help with weight loss.

A typical dose of 5-HTP is 300-500 mg taken daily in once or divided into two doses. If you’re experiencing any anxiety over your weight, this might be the perfect supplement for you because it will reduce anxiety and also help you feel fuller faster.

  1. L-theanine is great for calm alertness

  2. Susan Wright says

    do you take them all or just pick one?

  3. Matthias Braun says

    Kava ist shurely the best of those. Tried all nothing helped like Kava Kava for opioid withdrawal
    adrenaline rebound. L-Theanin is also quite good… I drink it traditionally and have some Kava Kava Candys… For sleep nothing of those helped me even not Kava Kava (in my situation)

    • Tina Palladinetti says

      Try glycine it’s an amino acid that works very well I have not slept for a long time with the worst insomnia but since taking it I am finally falling asleep. You may have the MTHFR gene mutation so your methylation pathway is not working which may be the reason you can sleep. Get the pure grade powder as you may need a few teaspoons at night I take two & it has never failed.

    • Kava is also the most toxic and dangerous.

  4. What about for presentations/ shaky voice? I`ve tried Kava Kava Root and L-Theanine. Are they safe to have together, and how much should I take? How long does the effect last?

  5. I tried L-Theanine 750mg.
    When I took it at night it made me restless, had night terrors and drenching night sweats. I gave it a few more tries at night with the same results. I tried it during the daytime and it made me feel so tired and dizzy but yet a restless feeling and I felt unsafe to drive. I don’t understand why it gave me those results. I’m not taking any prescriptions meds. I only take a multivitamin for other supplements.

    • SupplementHQ says

      Hey Julie, 750 mg is a very, very large dose of L-Theanine. I can understand why your experience didn’t go as intended. We typically recommend 150 mg to 300 mg per serving. If your product is in powder form, then you can try taking 1/3 or 1/4th the serving size for a less system-shocking result.

    • Try gluten free

  6. And combine with gluten free taurine and htp5
