HelloPharmacist Scorecard of Standardized African Mango by Nature's Way

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 Jul 11, 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 2 of its 2 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

This product contains two active ingredients. African Mango seed extract (the IGOB 131 standardized form) is the primary ingredient, and glucomannan, a soluble dietary fiber, is the second.

Together they make up a two-ingredient formula. The capsule itself is plant-derived, and the inactive ingredients are cellulose — so there are no synthetic fillers or binders in the mix.

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 its ingredients' overall clinical evidence instead.

Moderate

Some clinical evidence supports its ingredients 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 ingredients' overall clinical evidence instead.
  • On file: Constipation — rated "Possibly Effective" (Glucomannan) (Natural Medicines).
  • On file: Diabetes — rated "Possibly Effective" (Glucomannan) (Natural Medicines).
  • On file: Hyperlipidemia — rated "Possibly Effective" (Glucomannan) (Natural Medicines).

The evidence for African Mango seed extract isn't solid yet. The data shows insufficient reliable evidence to rate its use for diabetes, high cholesterol, obesity, or metabolic syndrome — meaning studies haven't been large or well-designed enough to say whether it works for those purposes.

Glucomannan (the fiber in this product) has stronger backing: it's rated Possibly Effective for constipation, possibly effective for diabetes, and possibly effective for high cholesterol. For the most part, though, you're relying more on the fiber's evidence than on the African Mango extract's.

The evidence, ingredient by ingredient Irvingia Gabonensis Glucomannan

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 2 of the 2 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 2 of 2.
  • General safety write-ups exist for 2 of 2.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

African Mango seed extract is generally well tolerated short-term, but long-term safety and product quality aren't well established. The most common side effects are flatulence, headache, insomnia, and nausea.

There's one case on record of acute liver inflammation in someone taking 350 mg twice daily; it developed within four days of starting the supplement. Glucomannan is generally well tolerated when taken with plenty of water, but its most common side effects are abdominal pain, bloating, gas, diarrhea, nausea, and vomiting — especially at doses over 3 grams daily.

Rare but serious: if you don't drink enough liquid with it, glucomannan can cause choking or blockage in your throat or digestive tract, particularly when taken as a dry powder or tablet. During pregnancy, not enough safety data exists for either ingredient — talk with your doctor.

While breastfeeding, there's no reliable safety information for African Mango, and only limited data for glucomannan, so caution is advised.

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?
  • 2 of the 2 matched ingredients can interact with medications — Glucomannan, Irvingia Gabonensis.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: diabetes medications.
  • For scale: 2,052 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.

Check your diabetes medications first — African Mango can lower blood sugar and increase the risk of it dropping too low. If you take testosterone products, exercise caution because the extract may boost testosterone levels.

Because glucomannan can reduce how your body absorbs oral drugs, any prescription or over-the-counter medication you swallow should be reviewed with your pharmacist before you add this supplement.

Check your own medication Run your meds through the checker above

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.

If you take diabetes or testosterone medications, this product isn't a good match without close monitoring and your doctor's involvement. If you take other oral medications, the glucomannan fiber could reduce how well your body absorbs them.

The long-term safety isn't well nailed down. Talk with your pharmacist before starting, especially if you're on any prescription medications.

Glucomannan root extract1 drug type · 2,022 drugs

Oral Drugs

Theoretically, glucomannan may decrease absorption of drugs taken orally.
Due to its viscosity and bulking effects, there is concern that glucomannan can decrease the absorption of oral drugs. A small clinical study in healthy volunteers shows that taking glyburide 2.5 mg plus glucomannan 3.9 grams with breakfast reduces plasma levels of glyburide when compared with breakfast and glyburide alone. In addition, animal research demonstrates this effect on amoxicillin, but shows increased absorption of metronidazole. This mouse model also demonstrates that metronidazole elimination is prolonged, but amoxicillin elimination is enhanced by 38%; glucomannan may also affect the distribution of some drugs. To avoid changes in absorption, take glucomannan 30-60 minutes after taking oral drugs.

Antidiabetes Drugs

Theoretically, taking Irvingia gabonensis with antidiabetes drugs might increase the risk of hypoglycemia in some patients.
Human research shows that Irvingia gabonensis decreases blood sugar in diabetic patients being treated with antidiabetes agents. Monitor blood glucose levels closely. Dose adjustments might be necessary.

Likelihood Possible Evidence B
Testosterone

Theoretically, taking Irvingia gabonensis with testosterone products drugs might cause additive effects in some patients.
Animal research suggests that Irvingia gabonensis increases testosterone levels. The mechanism of action is unclear. Until more is known, advise patients taking testosterone to avoid using or use Irvingia gabonensis cautiously.

Standardized African Mango by Nature's Way: Common Questions

Does Standardized African Mango by Nature's Way interact with any medications?
Yes. Based on its ingredients, Standardized African Mango has a known interaction with 2,051 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Standardized African Mango contains 2 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is 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.
Can I take this if I'm diabetic and on medication?
Not without talking to your doctor first. African Mango in this product can lower blood sugar, and combined with diabetes medications, there's a real risk of your blood sugar dropping too low. Your doctor would need to watch your levels closely and possibly adjust your medication dose.
What are the most common side effects?
From the African Mango extract: flatulence, headache, insomnia, and nausea. From the glucomannan fiber: bloating, gas, abdominal pain, diarrhea, nausea, and vomiting — especially if you take more than 3 grams daily without enough water.
Is this safe to take while breastfeeding?
The safety data isn't there. There's no reliable information on the African Mango extract while breastfeeding, and only limited data for glucomannan. Talk with your doctor or pharmacist for personalized advice.
Does this actually work for weight loss or high cholesterol?
The evidence for African Mango extract isn't established enough to rate. Glucomannan, the fiber in this product, is rated Possibly Effective for high cholesterol and constipation, and Possibly Effective for diabetes, so that's where the stronger evidence sits.
Can glucomannan block my digestive system?
Yes, but only if you don't take it properly. Choking and intestinal or throat blockage are rare but serious risks, especially when taken as a dry powder or tablet without enough liquid. Always take it with plenty of water.
Is there anything else in this capsule besides the two active ingredients?
Just plant-derived cellulose for the capsule material itself. No synthetic fillers or binders — what you see on the label is what you get.
