HelloPharmacist Scorecard of Taurine by Intensive Nutrition

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

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.

This product contains one active ingredient: taurine, an amino acid. It's naturally present in your body and in many foods—especially meat and seafood.

The capsule also contains microcrystalline cellulose and magnesium stearate, which are inactive ingredients that help form and stabilize the capsule.

Does it work?

Moderate evidence
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

This product doesn't appear to be marketed for a specific use, so we graded Taurine's overall clinical evidence instead.

Moderate

Some clinical evidence supports Taurine for:

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.
  • Since the label doesn't commit to one use, we graded the ingredient's overall clinical evidence instead.
  • On file: Congestive heart failure (CHF) — rated "Possibly Effective" (Natural Medicines).
  • On file: Hepatitis — rated "Possibly Effective" (Natural Medicines).

The evidence for taurine comes down to what condition you're taking it for. Research suggests it may be possibly effective for hepatitis and congestive heart failure (CHF), a condition where the heart struggles to pump blood efficiently.

For weight loss, the data we hold rates taurine as possibly ineffective.

The evidence, ingredient by ingredient Taurine

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.

Taurine is generally well tolerated when taken by mouth in typical doses for up to a year. The most common side effects are constipation, diarrhea, and indigestion.

Serious adverse effects are rare but can include hypersensitivity reactions, especially in people with a history of allergies to sulfites or sulfonamides. Long-term safety beyond one year is less certain, so use only under medical guidance.

While taurine occurs naturally in breast milk, the safety of taking a taurine supplement during pregnancy or while breastfeeding is not well studied—talk with your doctor or pharmacist before using it during these times.

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 — Taurine.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: lithium.
  • For scale: 173 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 you take this product, check with your doctor or pharmacist about your blood pressure medications and lithium. Both carry Moderate-severity interactions with taurine that could change how these drugs work in your body.

The bottom line

Scorecard at a glanceFully disclosed formula with some supporting evidence behind its ingredients' uses. Moderate medication interactions have been identified, and safety information is well characterized.

Taurine may help with hepatitis or congestive heart failure, but it's not effective for weight loss. If you take blood pressure medications or lithium, check with your doctor or pharmacist before starting—taurine could affect how these drugs work.

It's generally well tolerated in the short term, but long-term safety is unclear, so use it only under medical guidance.

Yes. Based on its ingredients, Taurine has a known interaction with 173 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Taurine 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.
Is taurine safe if I'm pregnant or breastfeeding?
The data we hold rates taurine as likely safe during pregnancy and lactation. That said, the safety of taurine supplements during these times isn't well studied, so there's not enough information to know for certain. Talk with your doctor or pharmacist before using it while pregnant or breastfeeding—they can help you weigh the pros and cons for your situation.
What are the most common side effects?
Constipation, diarrhea, and indigestion are the most common side effects when taurine is taken by mouth. Serious allergic reactions are rare but can happen, especially if you have a history of allergies to sulfites or sulfonamides.

Taurine is generally well tolerated for up to one year. Long-term safety beyond that is less certain, so if you're thinking of using it long-term, use only under medical guidance.
Does taurine actually help with weight loss?
According to the data we hold, taurine is rated as possibly ineffective for obesity, so it's not a reliable choice for weight loss.
What is taurine, and where does it come from?
Taurine is an amino acid your body makes naturally and that you get from foods like meat and seafood. This supplement provides it in capsule form.
