HelloPharmacist Scorecard of Power Stress 200 mg by Dr. Seth's Vitamin Vibrations

Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.

From our pharmacy team — supplement deep dive

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Jul 11, 2026

What’s inside

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

Power Stress contains one active ingredient: 200 mg of Suntheanine, a form of theanine, an amino acid that occurs naturally in tea leaves. The capsule also contains inactive ingredients (microcrystalline cellulose, cellulose, and leucine) that help deliver the active ingredient.

Does it work?

Not established
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Not established

The graded evidence we hold for these ingredients covers different conditions than the ones this product is marketed for, so there's no established rating for its stated use — see Theanine's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: support relaxation and reduce irritability and low mood.
  • We looked for evidence on: Stress, Generalized anxiety disorder (GAD), Depression, Insomnia, Anxiety, Mood support — and 1 related terms.
  • The closest evidence on file: Theanine is rated "Insufficient Reliable Evidence To Rate" for Generalized anxiety disorder (GAD) (Natural Medicines).
  • Also on file: Theanine is rated "Insufficient Reliable Evidence To Rate" for Depression, Insomnia, Stress.

Theanine is possibly effective for cognitive function — some evidence supports its use for mental clarity and focus. For age-related cognitive decline, Alzheimer disease, generalized anxiety disorder, obsessive-compulsive disorder, and cancer, the evidence in our data is insufficient to rate whether it works or doesn't.

If you're taking this for one of those other reasons, talk with your pharmacist about what the current research shows.

The evidence, ingredient by ingredient Theanine

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Theanine is generally well tolerated in healthy adults for short-term use, but we don't have solid data on long-term safety. The most common side effects are headaches and drowsiness; some people report longer sleep and more vivid dreams.

One pediatric case of facial tics was reported after starting theanine, but the tics stopped when the supplement was discontinued and the child had a history of tics beforehand, so a clear link wasn't established. There isn't enough safety data on theanine in pregnancy or while breastfeeding.

The safety information advises against use during both — talk with your OB or midwife before taking it if you're pregnant or nursing.

Side effects, ingredient by ingredient Theanine

Meds to double-check

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Theanine.
  • The most serious interaction on file is rated Moderate.
  • For scale: 565 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

Before starting Power Stress, double-check it with your blood pressure medications — theanine could lower your pressure further. Also run it past your pharmacist if you take any sedating drugs like sleep aids or anxiety medications, since additive drowsiness is possible.

Serotonin-related drugs (like certain antidepressants) show conflicting data, so mention those too.

The bottom line

Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and safety information is well characterized.

Power Stress may help with focus and mental clarity if the evidence holds up for you. If you take blood pressure medication or sedating drugs, check with your pharmacist first — theanine could enhance their effects.

It's meant for short-term use in healthy adults; long-term safety isn't clear.

Suntheanine3 drug types · 565 drugs

Antihypertensive Drugs

Theanine might lower blood pressure, potentiating the effects of antihypertensive drugs.
Animal research shows that theanine can lower blood pressure in spontaneously hypertensive animals. Theoretically, concomitant use of theanine and antihypertensive drugs might potentiate the antihypertensive activity.

Likelihood Possible Evidence D
Cns Depressants

Theoretically, theanine might have additive sedative effects when used in conjunction with CNS depressants. However, it is unclear if this concern is clinically relevant.
Theoretically, theanine may compete with glutamate and/or increase plasma gamma-aminobutyric acid (GABA) levels, which could cause CNS depression. In one clinical study, some subjects taking oral theanine reported drowsiness.

Likelihood Unlikely Evidence D
Serotonergic Drugs

Clinical studies regarding the effects of L-theanine on serotonin levels are conflicting. Some studies suggest it can increase serotonin levels in the brain while others report that it may decrease them. Nevertheless, there have been no reports of l-theanine being a causative agent in serotonergic-related side effects or serotonin syndrome.

Power Stress 200 mg by Dr. Seth's Vitamin Vibrations: Common Questions

Does Power Stress 200 mg by Dr. Seth's Vitamin Vibrations interact with any medications?
Yes. Based on its ingredients, Power Stress 200 mg has a known interaction with 565 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Power Stress 200 mg contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
What is theanine supposed to do?
Theanine may help with cognitive function — mental focus and clarity. It's found naturally in tea. The evidence for other uses like anxiety or cognitive decline in aging isn't solid enough in our data to say whether it works.
Can I take this while I'm pregnant?
There isn't enough safety data on theanine during pregnancy. The safety information advises against it. Talk with your OB or midwife before taking it — they can weigh the pros and cons for your specific situation.
Can I take this while breastfeeding?
There isn't enough safety data on theanine while breastfeeding, and the safety information advises against it. Check with your doctor or pharmacist if you're nursing and considering this supplement.
What side effects might I notice?
Headaches are the most common side effect. Some people also report drowsiness, longer sleep, or more vivid dreams. These are usually mild, but if they bother you, stop taking it and talk with your pharmacist.
How long can I safely take this?
Theanine is generally well tolerated for short-term use in healthy adults. Long-term safety hasn't been well studied, so don't take it indefinitely without checking in with your pharmacist about whether that makes sense for you.
Is this a replacement for sleep medication or anti-anxiety drugs?
No — the evidence for generalized anxiety and obsessive-compulsive disorder is insufficient in our data. If you're taking prescription medications for those conditions, don't replace them with this. Always talk with your doctor before stopping or changing any medication.
