HelloPharmacist Scorecard of Hoodia Gordonii 400 mg by OL Olympian Labs

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: 400 mg of hoodia gordonii, a plant extract traditionally used as an appetite suppressant. It also includes inactive ingredients — the vegetable capsule itself, rice flour, microcrystalline cellulose, and silica — which are fillers and binders that help hold the capsule together.

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 Hoodia's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: appetite suppression and weight management.
  • We looked for evidence on: Obesity, weight loss, food cravings, hunger control.
  • The closest evidence on file: Hoodia is rated "Insufficient Reliable Evidence To Rate" for Obesity (Natural Medicines).

The evidence for hoodia gordonii in treating obesity is insufficient to rate in our data. While the plant has been studied and marketed as an appetite suppressant, we don't hold reliable evidence that it works for weight loss.

The evidence, ingredient by ingredient Hoodia

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.

Hoodia has limited safety data, and side effects have been reported — including disturbances in skin sensation, headache, dizziness, giddiness, and nausea. There's also concern that it may increase blood pressure and heart rate.

The safety data advises against use during pregnancy and while breastfeeding due to insufficient information.

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 — Hoodia.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: diabetes medications.
  • For scale: 262 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 medications (antihypertensives), beta-blockers, insulin, and antidiabetes drugs all carry Moderate risk with hoodia. Check your exact medications — all of them — with the search tool on this page before you take this product.

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.

This product is a single-ingredient supplement with documented interactions with blood pressure, heart rate, diabetes, and insulin medications — a significant list. If you take any medication for blood pressure, heart rate, or blood sugar control, talk with your doctor or pharmacist before starting it.

Even if you don't take those drugs, the limited safety profile and reported side effects mean it's worth a conversation with your own healthcare provider first.

Hoodia gordonii4 drug types · 262 drugs

Antidiabetes Drugs

Animal research shows that a steroid glycoside of hoodia, gordonoside F, increases glucose-stimulated insulin secretion by activating GPR119. This effect enhances glucose disposal. Theoretically, concomitant use of hoodia with antidiabetes medications may enhance blood glucose-lowering effects and increase the risk of hypoglycemia. Some antidiabetes medications include glimepiride (Amaryl), glyburide (DiaBeta, Glynase PresTab, Micronase), insulin, pioglitazone (Actos), rosiglitazone (Avandia), chlorpropamide (Diabinese), glipizide (Glucotrol), tolbutamide (Orinase), and others.

Likelihood Possible Evidence D
Antihypertensive Drugs

Clinical research shows that hoodia can increase blood pressure. Theoretically, concomitant use of hoodia with antihypertensive drugs might decrease the effectiveness of the antihypertensive drugs and increase the risk of hypertension. Some antihypertensive drugs include captopril (Capoten), enalapril (Vasotec), losartan (Cozaar), valsartan (Diovan), diltiazem (Cardizem), Amlodipine (Norvasc), hydrochlorothiazide (HydroDiuril), furosemide (Lasix), and many others.

Likelihood Possible Evidence D
Beta-Blockers

Evidence from in vitro research shows that hoodia may stimulate beta-adrenergic receptors. Also, clinical research shows that hoodia can increase blood pressure and heart rate. Theoretically, using hoodia with beta-blockers might decrease the effects of these medications. Some beta-blocker drugs include atenolol (Tenormin), metoprolol (Lopressor, Toprol XL), nadolol (Corgard), and propranolol (Inderal).

Likelihood Possible Evidence D
Insulin

Animal research shows that a steroid glycoside of hoodia, gordonoside F, increases glucose-stimulated insulin secretion by activating GPR119. Theoretically, concomitant use of hoodia with insulin may enhance the blood glucose-lowering effects of insulin. Blood glucose levels should be monitored.
