HelloPharmacist Scorecard of Taurine 500 mg by Progressive Professional from Progressive Laboratories

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 Sep 17, 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.

This product contains one active ingredient: taurine 500 mg per capsule. Taurine is a compound your body makes naturally and also gets from food (especially meat and fish).

The capsule also holds inactive ingredients—rice flour and gelatin—which are fillers and the capsule shell.

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 is mixed and modest. It's rated possibly effective for hepatitis and congestive heart failure (CHF), meaning there's some clinical support but the data isn't yet strong enough to call it proven.

For weight loss, the evidence is rated possibly ineffective—taurine doesn't appear to help with obesity on the basis of current research.

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 in typical doses for up to one year. The most common mild side effects are constipation, diarrhea, and dyspepsia (indigestion).

Serious adverse effects are rare, though case reports of hypersensitivity reactions have occurred in people with a history of allergies to sulfonamides, sulfites, and other allergens. Long-term safety is less certain, and taurine supplement safety hasn't been well studied—use only under medical guidance if taking it regularly.

While taurine occurs naturally in breast milk, supplement safety during pregnancy and lactation is rated likely safe, though data is limited.

Side effects, ingredient by ingredient Taurine

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 — 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.

Blood pressure-lowering medications (antihypertensive drugs) are the top concern—taurine may increase the drop in blood pressure. Lithium, used for mood disorders, is a moderate-risk interaction because taurine may raise lithium levels.

Check your exact medications before starting.

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.

Consider taurine if you're exploring support for heart failure or hepatitis under your doctor's supervision—but the evidence is preliminary. If you take blood pressure medications or lithium, talk with your pharmacist or doctor before starting; the interactions are real and potentially meaningful.

Even though taurine is generally well tolerated short-term, check with your healthcare provider to make sure it fits your individual situation.
