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 2 active ingredients: ActivAMP Gynostemma pentaphyllum Extract (jiaogulan) and rose hip extract. Jiaogulan is an adaptogenic herb traditionally used to support metabolic function and blood sugar control.

Rose hip, derived from the fruit of the rose plant, is included for its vitamin C content and antioxidant properties. The capsule also contains several inactive ingredients — vegetable cellulose, microcrystalline cellulose, tapioca starch, dextrin, ascorbyl palmitate, and silica — which serve as fillers, binders, and flow agents.

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
Moderate

Some clinical evidence supports this product's ingredients for its stated purpose, but it isn't conclusive.

Why this rating?
  • The label markets this product for: AMPK activation for cellular energy and aging support.
  • We looked for evidence on: Aging, Cardiovascular disease (CVD), Diabetes, Hypercholesterolemia, Hyperlipidemia, Hypertension — and 4 related terms.
  • The strongest evidence on file: Jiaogulan is rated "Possibly Effective" for Diabetes (Natural Medicines).
  • Also on file: Jiaogulan is rated "Insufficient Reliable Evidence To Rate" for Cardiovascular disease (CVD), Hypercholesterolemia, Hypertension, Obesity, and more.

For jiaogulan: clinical research supports it as possibly effective for diabetes. The evidence for athletic performance, cancer, cardiovascular disease, fatty liver disease, and respiratory infections is insufficient to rate at this time.

For rose hip: it's possibly effective for postoperative pain and osteoarthritis. Evidence for high cholesterol (hyperlipidemia) is insufficient to rate.

The product is marketed as an AMPK activator, but effectiveness ratings in our data are tied to the individual ingredients and their traditional uses — not to AMPK activation itself.

The evidence, ingredient by ingredient Jiaogulan Rose Hip

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.

Jiaogulan is generally well tolerated when used short-term (up to 4 months in studies), but long-term safety is not well established. The most common side effects are diarrhea and nausea; dry mouth, dizziness, and insomnia have also been reported.

Avoid jiaogulan during pregnancy because safety hasn't been established and it may affect the developing baby; also avoid while breastfeeding due to insufficient safety data. Rose hip from Rosa canina and Rosa damascena is generally well tolerated as a food, but supplement safety is less studied.

Common side effects include flatulence and loose stools; vertigo and headache have been reported rarely. Gastrointestinal reactions — such as cramps, acid reflux, constipation, diarrhea, nausea, and vomiting — have been reported, though in most cases they occurred at the same rate as placebo.

Pregnancy and lactation data for rose hip is not on file.

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 — Jiaogulan, Rose Hip.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; immunosuppressants / transplant drugs; cancer treatments; diabetes medications; lithium.
  • For scale: 416 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 these medication types with your pharmacist: blood thinners and antiplatelet drugs (Moderate risk), diabetes medications (Moderate), estrogen-based hormones including birth control (Moderate), immunosuppressants (Moderate), lithium (Moderate), and chemotherapy drugs such as alkylating agents and antitumor antibiotics (Moderate). If you also take aspirin or warfarin, the risk is lower but worth mentioning.

The bottom line

Scorecard at a glanceFully disclosed formula with some supporting evidence for its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

This product is worth considering if you're interested in blood sugar support or general metabolic health and have no significant drug interactions. However, if you take blood thinners, diabetes medications, immune-suppressing drugs, estrogen-based hormones, or lithium, you'll need to check with your pharmacist first.

Long-term safety for jiaogulan isn't well studied, and both ingredients can cause digestive upset in some people. Talk to your pharmacist before adding this to your regimen.

ActivAMP Gynostemma pentaphyllum Extract3 drug types · 327 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, jiaogulan might increase the risk of bleeding when taken with anticoagulant or antiplatelet drugs.
In vitro research suggests that jiaogulan has antiplatelet effects.

Likelihood Possible Evidence D
Antidiabetes Drugs

Theoretically, jiaogulan might increase the risk of hypoglycemia when taken with antidiabetes drugs.
Clinical research shows that jiaogulan can lower blood glucose levels.

Likelihood Possible Evidence B
Immunosuppressants

Theoretically, jiaogulan might decrease the effectiveness of immunosuppressive therapy.
Clinical and animal studies suggest that jiaogulan can stimulate the immune system.

Likelihood Possible Evidence D
ActivAMP Gynostemma pentaphyllum Extract full monograph & interactions

Rose Hip extract8 drug types · 213 drugs

Alkylating Agents

Theoretically, the antioxidant effects of rose hip might reduce the effectiveness of alkylating agents but might also reduce the oxidative damage caused by certain alkylating agents.
Rose hip contains vitamin C. The use of antioxidants like vitamin C during chemotherapy is controversial. There is concern that antioxidants could reduce the activity of chemotherapy drugs that generate free radicals, such as cyclophosphamide, chlorambucil, carmustine, busulfan, and thiotepa. In contrast, some researchers theorize that antioxidants might make chemotherapy more effective by reducing oxidative stress that could interfere with apoptosis (cell death) of cancer cells. Further, some animal research suggests that the antioxidant effects of rose hip might attenuate cyclophosphamide-induced testicular toxicity. More evidence is needed to determine what effect, if any, antioxidants found in rose hip, such as vitamin C, have on the effectiveness and adverse effects of chemotherapy.

Likelihood Possible Evidence D
Aluminum

Theoretically, rose hip might increase the amount of aluminum absorbed from aluminum compounds.
Rose hip contains vitamin C. Theoretically, vitamin C increases the absorption of aluminum. Concomitant use might increase aluminum absorption, but the clinical significance of this is unknown. Administer rose hip two hours before or four hours after antacids.

Likelihood Probable Evidence D
Anticoagulant/Antiplatelet Drugs

Theoretically, rose hip might reduce the effectiveness of anticoagulant or antiplatelet drugs.
In vitro and animal research suggests that a constituent of rose hip, rugosin E, can induce platelet aggregation. This has not been shown in humans. Theoretically, concomitant use of rose hip might reduce the effectiveness of antiplatelet or anticoagulant drugs.

Likelihood Possible Evidence D
Antitumor Antibiotics

Theoretically, the antioxidant effects of rose hip might reduce the effectiveness of antitumor antibiotics.
Rose hip contains the antioxidant vitamin C. There is concern that antioxidants might reduce the activity of chemotherapy drugs that generate free radicals, such as antitumor antibiotics. In contrast, other researchers theorize that antioxidants might make antitumor antibiotic chemotherapy more effective by reducing oxidative stress that could interfere with apoptosis (cell death) of cancer cells. More evidence is needed to determine what effects, if any, antioxidants such as vitamin C have on antitumor antibiotic chemotherapy.

Likelihood Possible Evidence D
Estrogens

Theoretically, rose hip might increase blood levels of estrogens.
Rose hip contains vitamin C. Increases in plasma estrogen levels of up to 55% have occured under some circumstances when vitamin C is taken concurrently with oral contraceptives or hormone replacement therapy, including topical products. It is suggested that vitamin C prevents oxidation of estrogen in the tissues, regenerates oxidized estrogen, and reduces sulfate conjugation of estrogen in the gut wall. When tissue levels of vitamin C are high, these processes are already maximized and supplemental vitamin C does not have any effect on estrogen levels. However, increases in plasma estrogen levels may occur when women who are deficient in vitamin C take supplements.

Likelihood Possible Evidence D
Lithium

Theoretically, rose hip might increase blood levels of lithium.
Rose hip is thought to have diuretic properties. Theoretically, due to these potential diuretic effects, rose hip might reduce excretion and increase levels of lithium. The dose of lithium might need to be decreased.

Likelihood Probable Evidence D
Aspirin

Theoretically, rose hip might reduce the clearance of aspirin; however, its vitamin C content is likely too low to produce clinically significant effects.
Rose hip contains vitamin C. It has been suggested that acidification of the urine by vitamin C can decrease the urinary excretion of salicylates, increasing plasma salicylate levels. However, short-term use of up to 6 grams daily of vitamin C does not seem to affect urinary pH or salicylate excretion. The vitamin C content of rose hip is typically about 500 mg per 100 grams. Thus, a clinically significant interaction between rose hip and aspirin is unlikely.

Likelihood Unlikely Evidence B
Warfarin (Coumadin)

Theoretically, rose hip might reduce the effectiveness of warfarin; however, its vitamin C content is likely too low to produce clinically significant effects.
Rose hip contains vitamin C. High doses of vitamin C may reduce the response to warfarin, possibly by causing diarrhea and reducing warfarin absorption. This occurred in two people who took up to 16 grams daily of vitamin C, and resulted in decreased prothrombin time. Lower doses of 5-10 grams daily of vitamin C can also reduce warfarin absorption, but this does not seem to be clinically significant. The vitamin C content of rose hip is typically about 500 mg per 100 grams. Thus, a clinically significant interaction between rose hip and warfarin is unlikely.

AMPK Activator by Life Extension: Common Questions

Does AMPK Activator by Life Extension interact with any medications?
Yes. Based on its ingredients, AMPK Activator has a known interaction with 416 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
AMPK Activator 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 on blood thinners?
Not without checking with your pharmacist first. Both ingredients in this product can interfere with how blood thinners work — jiaogulan may increase bleeding risk, while rose hip may reduce their effectiveness. Your pharmacist needs to review your specific medication.
Will this help me lose weight or lower my blood sugar?
Jiaogulan is possibly effective for diabetes and clinical research shows it can lower blood glucose. However, this product is not studied for weight loss, and you should never use it to replace or reduce your diabetes medication without your doctor's approval.
What are the most common side effects I might notice?
From jiaogulan: diarrhea, nausea, dry mouth, dizziness, or insomnia. From rose hip: flatulence and loose stools. Most people tolerate it well, especially in the short term.
Is this safe during pregnancy or while breastfeeding?
No. Jiaogulan should be avoided during pregnancy because its safety hasn't been established and it may affect the developing baby, and it shouldn't be used while breastfeeding due to insufficient safety data. Pregnancy and lactation information for rose hip isn't available in our data — talk to your doctor or pharmacist for personalized advice.
How long can I safely take this product?
Jiaogulan has been studied for up to 4 months and appears well tolerated over that period, but long-term safety isn't well studied. Rose hip supplement safety is also less established than food use. Discuss duration with your pharmacist or doctor.
