HelloPharmacist Scorecard of Hoodia Liquid Extract by Source Naturals

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.

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: hoodia gordonii stem extract, a plant extract traditionally used to support appetite control. The liquid also includes grain alcohol, purified water, vegetable glycerin, and peppermint oil as inactive ingredients.

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 support.
  • 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 in weight management is insufficient to rate reliably. While the plant has a traditional history of use, we don't have enough high-quality research data on file to confirm whether it actually works for obesity.

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 has been associated with side effects and product quality concerns. Reported adverse effects include disturbances of skin sensation, headache, dizziness, giddiness, and nausea.

There is also concern that hoodia may increase blood pressure and heart rate. The safety data advises against use during pregnancy and while breastfeeding due to insufficient safety information.

If you're pregnant, planning to become pregnant, or breastfeeding, talk with your doctor or pharmacist before using this product.

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 — 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.

Before taking this product, double-check with your doctor or pharmacist if you take blood pressure medications (such as captopril, enalapril, losartan, or valsartan), beta-blockers (such as atenolol or metoprolol), diabetes medications, or insulin. Hoodia may reduce how well blood pressure drugs work and increase the risk of low blood sugar with diabetes medications.

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.

Hoodia Liquid Extract may appeal to people exploring traditional appetite-support options, but the evidence that it works is not established in our data. If you take blood pressure medications, heart drugs, diabetes medications, or insulin, you should check your specific medications with your doctor or pharmacist before starting this product.

The limited safety profile and reported side effects also warrant a conversation with your healthcare provider to see if it's right for you.

Hoodia gordonii stem extract4 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.

Hoodia Liquid Extract by Source Naturals: Common Questions

Does Hoodia Liquid Extract by Source Naturals interact with any medications?
Yes. Based on its ingredients, Hoodia Liquid Extract has a known interaction with 262 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Hoodia Liquid Extract 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 hoodia safe to use while I'm pregnant or breastfeeding?
No—the safety data advises against it. There isn't enough information to know it's safe during pregnancy or while breastfeeding, so talk with your doctor or pharmacist before using it in these situations.
What side effects has hoodia been reported to cause?
Users have reported headache, dizziness, giddiness, nausea, and disturbances of skin sensation. There's also concern that it may raise blood pressure and heart rate.
Does hoodia actually work for weight loss?
The evidence we hold is insufficient to rate it reliably. While hoodia has traditional use for appetite control, we don't have enough research data to confirm it works.
Why should I be careful if I take blood pressure or diabetes medication?
Hoodia can raise blood pressure (which may weaken your blood pressure drugs) and may lower blood sugar (which could increase the risk of low blood sugar if you're on diabetes medication or insulin). Your doctor or pharmacist should monitor this combination.
What's in this liquid besides the hoodia extract?
The liquid contains grain alcohol, purified water, vegetable glycerin, and peppermint oil as inactive ingredients to deliver the active extract.
