HelloPharmacist Scorecard of Super MiraForte With Standardized Lignans by Life Extension

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 7 of its 7 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

This product contains 7 ingredients. The active ones are chrysin (a plant compound), olive leaf extract, maca (a root vegetable), muira puama (a plant used traditionally in herbal medicine), stinging nettle extract, HMRlignan (a lignan from Norway spruce), and piperine (the active compound in black pepper, added to help absorption).

The remaining ingredients are fillers and capsule material—gelatin, microcrystalline cellulose, maltodextrin, vegetable stearate, and silica.

Does it work?

Insufficient 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
Insufficient

There isn't enough reliable clinical evidence to rate this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: maintain healthy testosterone and sexual function.
  • We looked for evidence on: Age-related testosterone deficiency, Erectile dysfunction (ED), Sexual desire, Sexual dysfunction, Antidepressant-induced sexual dysfunction, Male infertility — and 4 related terms.
  • The closest evidence on file: Maca is rated "Insufficient Reliable Evidence To Rate" for Antidepressant-induced sexual dysfunction (Natural Medicines).
  • Also on file: Maca is rated "Insufficient Reliable Evidence To Rate" for Chronic fatigue syndrome (CFS), Fatigue, Sexual desire, Age-related testosterone deficiency, and more.
  • Also on file: Muira Puama is rated "Insufficient Reliable Evidence To Rate" for Sexual dysfunction.

The evidence for this product's ingredients is sparse. Stinging nettle is rated possibly effective for diabetes, meaning some clinical research supports its use.

The other ingredients—chrysin, olive leaf extract, maca, and muira puama—all have insufficient reliable evidence for their listed uses, so we don't have solid data yet showing how well they work. HMRlignan and piperine effectiveness data aren't on file.

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 3 of the 5 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 5 of 5.
  • General safety write-ups exist for 5 of 5.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Chrysin is generally well tolerated in the short term, but long-term safety hasn't been studied. Avoid it during pregnancy and breastfeeding—there's not enough data to know it's safe.

Olive leaf extract seems well tolerated overall; the most common side effects reported are headache and stomach discomfort, though one patient reported skin issues. Maca and muira puama are generally tolerated as foods or traditional supplements, but long-term supplement safety hasn't been established; avoid both during pregnancy and breastfeeding.

Stinging nettle is commonly well tolerated but may cause constipation or diarrhea. Rare cases of liver injury have been reported with stinging nettle in combination products.

Avoid stinging nettle during pregnancy and breastfeeding. We don't have adverse effect or safety data on file for HMRlignan or piperine.

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 5 matched ingredients can interact with medications — Stinging Nettle, Chrysin.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; diabetes medications; lithium.
  • For scale: 514 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.

General Statements

Foundation for longer life

Helps maintain healthy levels of testosterone

Maintaining normal testosterone levels is one of the most important steps men can take to regain their health and improve their performance. If you’re over 40, odds are you’re already starting to feel the effects of low testosterone. Research shows that by age 60, men typically produce 60% less testosterone than they did at age 20.33 The reduction of testosterone levels has been associated with the blues, cognitive decline, reduced sex drive and abdominal fat gain. Normal testosterone has been associated with maintaining a healthy cardiovascular system.

Muira puama is a rainforest herb classified in the Brazilian Pharmacopoeia as an aphrodisiac. In a trial of men with decreased libido and other sexual issues, 62% of those taking muira puama reported positive results in regard to libido, while 51% of those with a common sexual problem felt that the herb was helpful.37 A second trial examined men with decreased libido and found that 85% of the test subjects taking muira puama enjoyed an enhanced libido, 90% had improved sexual function, and 100% of test subjects experienced an increase in intercourse frequency.38

These lignans convert to enterolactone in the intestine. They are then rapidly absorbed into the bloodstream where they provide significant biological effects.39 Enterolactone has demonstrated biological effects that are of particular importance for the aging prostate gland.40,41

Chrysin9 drug types · 358 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, chrysin might increase the risk of bleeding when taken with anticoagulant or antiplatelet drugs.
In vitro evidence suggests that chrysin might inhibit platelet aggregation.

Likelihood Possible Evidence D
Aromatase Inhibitors

Theoretically, chrysin might increase the effects and adverse effects of aromatase inhibitors.
In vitro research suggests that chrysin might decrease estrogen synthesis by acting as an aromatase (estrogen synthetase) inhibitor..

Likelihood Possible Evidence D
Contraceptive Drugs

Theoretically, chrysin might reduce the efficacy of estrogen-containing contraceptive drugs.
In vitro research suggests that chrysin might have antiestrogenic activity.

Likelihood Possible Evidence D
Diclofenac (Voltaren, Others)

Theoretically, chrysin might increase the effects and adverse effects of diclofenac.
In vitro research suggests that chrysin and its sulfate conjugate inhibit diclofenac metabolism. It is speculated that chrysin and its sulfate conjugate reduce the metabolism of diclofenac by inhibiting cytochrome P450 2C9. This effect has not been reported in humans.

Likelihood Possible Evidence D
Estrogens

Theoretically, chrysin might decrease the effects of estrogen therapy.
In vitro research suggests that chrysin might have antiestrogenic activity.

Likelihood Possible Evidence D
Mephenytoin (Mesantoin)

Theoretically, chrysin might increase the effects and adverse effects of mephenytoin.
In vitro research suggests that chrysin and its sulfate and glucuronide conjugates inhibit S-mephenytoin metabolism. It is speculated that chrysin and its conjugates reduce the metabolism of S-mephenytoin by inhibiting cytochrome P450 2C19. This effect has not been reported in humans.

Likelihood Possible Evidence D
Cytochrome P450 1A2 (Cyp1A2) Substrates

Theoretically, chrysin might increase levels of drugs metabolized by CYP1A2.
In vitro research suggests that chrysin inhibits CYP1A2 isozymes. However, chrysin does not appear to inhibit CYP1A2-dependent caffeine metabolism in animals. Due to chrysin's low bioavailability and rapid metabolism to glucuronide and sulfate conjugates, this interaction is unlikely.

Likelihood Unlikely Evidence D
Glucuronidated Drugs

Theoretically, chrysin might increase the clearance of drugs that are UGT1A1 substrates, thereby reducing their effectiveness.
In vitro research suggests that chrysin might induce UDP-glucuronosyltransferase 1A1 (UGT1A1).

Likelihood Unlikely Evidence D
Testosterone

Theoretically, chrysin might increase the effects and adverse effects of testosterone.
In vitro research suggests that chrysin and its sulfate conjugate inhibit testosterone metabolism. It is speculated that chrysin and its sulfate conjugate reduce the metabolism of testosterone by inhibiting cytochrome P450 3A4. This effect has not been reported in humans.

Likelihood Possible Evidence D

Nettle (Urtica dioica) Methanolic extract4 drug types · 164 drugs

Antidiabetes Drugs

Theoretically, stinging nettle might have additive effects with antidiabetes drugs.
Clinical research shows that stinging nettle might decrease blood glucose levels in patients with diabetes.

Likelihood Possible Evidence B
Diuretic Drugs

Theoretically, combining stinging nettle with diuretic drugs may have additive effects.
Animal research suggests that the above ground parts and roots of stinging nettle may have a diuretic effect.

Likelihood Possible Evidence D
Lithium

Theoretically, stinging nettle might reduce excretion and increase levels of lithium.
Animal research suggests that stinging nettle has diuretic and natriuretic properties, which could alter the excretion of lithium. The dose of lithium might need to be decreased.

Likelihood Possible Evidence D
Warfarin (Coumadin)

There is some concern that stinging nettle might decrease the effects of anticoagulant drugs such as warfarin.
Stinging nettle contains a significant amount of vitamin K. When taken in large quantities, this might interfere with the activity of warfarin.

Super MiraForte With Standardized Lignans by Life Extension: Common Questions

Does Super MiraForte With Standardized Lignans by Life Extension interact with any medications?
Yes. Based on its ingredients, Super MiraForte With Standardized Lignans has a known interaction with 514 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Super MiraForte With Standardized Lignans contains 7 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.
Is this safe to take if I'm pregnant or breastfeeding?
The data advises against it. Chrysin, maca, muira puama, and stinging nettle all lack enough safety information during pregnancy and breastfeeding. Talk with your doctor or pharmacist before taking this product if you're pregnant, planning to become pregnant, or breastfeeding.
What are the most common side effects?
The most commonly reported side effects are from olive leaf extract—headache and stomach discomfort. Stinging nettle may cause constipation or diarrhea. Fresh, uncooked maca may cause stomach pain. Rare cases of liver injury have been reported with stinging nettle in combination products.
Can I take this long-term?
Long-term safety hasn't been well studied for chrysin, maca, muira puama, or concentrated olive supplements. Short-term use seems okay for most, but we don't have good data on safety beyond that. Talk with your pharmacist about how long you plan to take it.
Does this product actually work?
The evidence is limited. Stinging nettle is possibly effective for diabetes based on some clinical research. The other ingredients don't have reliable evidence yet—that doesn't mean they don't work, just that solid studies are missing.
What is maca supposed to do?
Traditionally it's been used for sexual function, athletic performance, and hormonal balance, but we don't have reliable evidence backing those uses in our data. The ingredient list shows it's included, but we can't confirm it's effective for any specific condition.
Why does this product include piperine?
Piperine is black pepper extract. It's commonly added to herbal supplements to help your body absorb the other ingredients better. We don't have safety or interaction data on file for it in this product.
