HelloPharmacist Scorecard of Guggul E & Z 99% 75 mg by Vital Nutrients

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 Aug 6, 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.

Guggul E & Z 99% contains one active ingredient: guggul lipid, a resin extract from the guggul tree that has been used in traditional medicine for centuries. Each capsule delivers 75 mg of this concentrated extract.

The capsule itself is made from cellulose and also contains rice powder and leucine as inactive ingredients.

Does it work?

Couldn't assess
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 assessable

This is a single-ingredient Guggul product and its label doesn't state a use — see Guggul's own graded uses on its monograph.

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.

The evidence for guggul is mixed. It's rated possibly ineffective for obesity, meaning studies haven't shown it reliably helps with weight loss.

For acne, high cholesterol (hypercholesterolemia), and hemorrhoids, we don't yet have enough reliable evidence to know whether it works — the research simply isn't there to say one way or the other.

The evidence, ingredient by ingredient Guggul

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.

Guggul is generally well tolerated when taken by mouth, but digestive upset can happen — belching, bloating, diarrhea, nausea, headache, vomiting, and an unpleasant taste are the most common side effects. Skin reactions (rash, itching, swelling) also occur and appear to be dose-dependent; they're more common at higher doses.

In rare cases, a serious muscle breakdown condition (rhabdomyolysis) has been reported. Some people may have an allergic reaction within minutes of taking it.

Guggul is not recommended during pregnancy because it may stimulate the uterus and its safety isn't established. There isn't enough safety information to use it while breastfeeding.

Talk with your doctor or pharmacist before taking guggul if you're pregnant, nursing, or planning to become pregnant.

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 — Guggul.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs.
  • For scale: 758 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.

Double-check with your doctor or pharmacist before taking this product if you're on blood thinners or antiplatelet drugs (like warfarin or aspirin), heart medications (propranolol, diltiazem), birth control pills, estrogen therapy, thyroid hormone replacement, tamoxifen, or any other drugs your liver breaks down quickly — guggul can interfere with how these work.

The bottom line

Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

Guggul may interest you if you've read about its traditional uses, but the evidence it actually works for obesity, acne, or high cholesterol is either weak or absent. More importantly, it interacts with a large number of medications — especially blood thinners, heart drugs, birth control, and thyroid replacement — so you need to check your exact prescriptions before starting.

Pregnancy and breastfeeding are off-limits. Talk it through with your doctor or pharmacist to see if it fits your situation.

What is guggul, and what is it supposed to do?
