What’s inside

Partial disclosure
Ingredient Transparency · database check
Partial

Most active ingredients list an amount, but at least one is hidden in a blend or missing.

Why this rating?
  • The label discloses an exact amount for 6 of its 11 active ingredients.
  • “Betaine Anhydrous” is listed as a grouped ingredient — the label gives one combined amount (2,500 mg) without saying how much of each component you get.

Ergonine Tropical Twist contains 11 ingredients, including amino acids (L-glutamine, L-alanine, L-carnitine-L-tartrate), minerals (calcium, creatine anhydrous), choline bitartrate, glycerol, asafoetida root extract, and three proprietary blends we cannot detail individually: TruGlutamine Blend, Hydroxy-Isocaproic Acid, and PerfomaLean Blend. The inactive ingredients are citric acid, natural and artificial flavors, silicon dioxide, sucralose, and acesulfame potassium.

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: athletic performance and muscle recovery support.
  • We looked for evidence on: Athletic performance, muscle strength, exercise performance, workout recovery.
  • The strongest evidence on file: Glycerol is rated "Possibly Effective" for Athletic performance (Natural Medicines).
  • Also on file: Creatine is rated "Possibly Effective" for Athletic performance, Muscle strength.
  • Also on file: Choline is rated "Possibly Ineffective" for Athletic performance.

The evidence for most of these ingredients is limited or mixed. L-glutamine is effective for sickle cell disease and possibly effective for HIV/AIDS-related wasting, postoperative recovery, and critical illness.

L-carnitine is effective for L-carnitine deficiency and possibly effective for high cholesterol and heart failure. Calcium is effective for kidney disease, dyspepsia, and low blood calcium, and likely effective for osteoporosis.

Creatine is possibly effective for muscle loss (sarcopenia), certain rare brain disorders, and muscle strength, but possibly ineffective for Huntington disease and bone density loss. Glycerol is likely effective for constipation and possibly effective for athletic performance.

For L-alanine, choline bitartrate, asafoetida, and the proprietary blends, the evidence is insufficient or not established in our data.

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 7 of the 8 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 8 of 8.
  • General safety write-ups exist for 8 of 8.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

L-glutamine is generally well tolerated in healthy adults but should be used only under medical supervision by people with kidney or liver disease. Common side effects include belching, bloating, constipation, diarrhea, nausea, and vomiting; headache and dizziness have also been reported.

L-carnitine is generally well tolerated at typical doses but can cause stomach upset, diarrhea, and a fish-like body odor at higher amounts. Calcium is well tolerated at recommended amounts; common effects are constipation, diarrhea, and bloating.

Creatine is generally well tolerated in healthy adults but those with kidney disease should be cautious; common side effects include dehydration, diarrhea, muscle cramps, and water retention. Choline at high doses (over 3.5 grams daily) can cause nausea, vomiting, diarrhea, and a fishy body odor.

Glycerol can cause bloating, diarrhea, nausea, dizziness, and headache. Asafoetida in large amounts may cause belching, flatulence, diarrhea, and headache.

Pregnancy and lactation safety varies by ingredient: L-glutamine, L-alanine, choline, and calcium are likely safe in pregnancy; creatine safety has not been established and should be avoided in pregnancy; asafoetida is likely unsafe in pregnancy and unsafe while breastfeeding. Breastfeeding safety data is limited for most ingredients — discuss with your doctor or pharmacist before use.

General Statements

Ergonine is a scientifically formulated blend of powerful ingredients designed to bring every athlete, bodybuilder, and physique enthusiast to the next level. Ergonine offers high amounts of quality ingredients, along with new blends and research to the sports industry. This formula is not based on theory or hype... it is based on existing research. Why has a product like this never made it to the market before? For starters, because no other company formulates for the consumer and to the level of PEScience. Additionally, this product is impossible for the mass-marketers of the industry to produce at a cost that is reasonable to the consumer. But PEScience puts their money into quality and formula, not marketing and gimmicks. Enjoy the science.

For each ingredient in Ergonine Tropical Twist with known interactions, here are the types of medications they can affect. Open any type for the detail — or search your exact drug in the checker above.

Calcium18 drug types · 168 drugs

Ceftriaxone (Rocephin)

Co-administration of intravenous calcium and ceftriaxone can result in precipitation of a ceftriaxone-calcium salt in the lungs and kidneys.
Avoid administering intravenous calcium in any form, such as parenteral nutrition or Lactated Ringers, within 48 hours of intravenous ceftriaxone. Case reports in neonates show that administering intravenous ceftriaxone and calcium can result in precipitation of a ceftriaxone-calcium salt in the lungs and kidneys. In several cases, neonates have died as a result of this interaction. So far there are no reports in adults; however, there is still concern that this interaction might occur in adults.

Likelihood Probable Evidence D
Dolutegravir (Tivicay)

Calcium seems to reduce levels of dolutegravir.
Advise patients to take dolutegravir either 2 hours before or 6 hours after taking calcium supplements. Pharmacokinetic research suggests that taking calcium carbonate 1200 mg concomitantly with dolutegravir 50 mg reduces plasma levels of dolutegravir by almost 40%. Calcium appears to decrease levels of dolutegravir through chelation.

Likelihood Probable Evidence B
Elvitegravir (Vitekta)

Calcium seems to reduce levels of elvitegravir.
Advise patients to take elvitegravir either 2 hours before or 2 hours after taking calcium supplements. Pharmacokinetic research suggests that taking calcium along with elvitegravir can reduce blood levels of elvitegravir through chelation.

Likelihood Probable Evidence B
Aluminum

Calcium citrate might increase aluminum absorption and toxicity. Other types of calcium do not increase aluminum absorption.
Calcium citrate can increase the absorption of aluminum when taken with aluminum hydroxide. The increase in aluminum levels may become toxic, particularly in individuals with kidney disease. However, the effect of calcium citrate on aluminum absorption is due to the citrate anion rather than calcium cation. Calcium acetate does not appear to increase aluminum absorption.

Likelihood Possible Evidence B
Bictegravir/Emtricitabine/Tenofovir Alafenamide (Biktarvy)

Calcium might decrease levels of bictegravir/emtricitabine/tenofovir alafenamide by reducing its absorption when taken in a fasting state.
Advise patients that bictegravir/emtricitabine/tenofovir alafenamide and calcium can be taken together if taken with food. However, if taken on an empty stomach, bictegravir/emtricitabine/tenofovir alafenamide should not be taken with, or 2 hours after, calcium containing products.

Likelihood Probable Evidence D
Bisphosphonates

Calcium reduces the absorption of bisphosphonates.
Advise patients to take bisphosphonates at least 30 minutes before calcium, but preferably at a different time of day. Calcium supplements decrease absorption of bisphosphonates.

Likelihood Probable Evidence C
Calcipotriene (Dovonex)

Taking calcipotriene with calcium might increase the risk for hypercalcemia.
Calcipotriene is a vitamin D analog used topically for psoriasis. It can be absorbed in sufficient amounts to cause systemic effects, including hypercalcemia. Theoretically, combining calcipotriene with calcium supplements might increase the risk of hypercalcemia.

Likelihood Possible Evidence B
Digoxin (Lanoxin)

Using intravenous calcium with digoxin might increase the risk of fatal cardiac arrhythmias.
Hypercalcemia increases the risk of fatal cardiac arrhythmias with digoxin. However, one retrospective analysis of clinical data suggests that intravenous calcium does not increase the risk of dysrhythmias or mortality in patients receiving digoxin.

Likelihood Possible Evidence B
Diltiazem (Cardizem, Others)

Theoretically, calcium may reduce the therapeutic effects of diltiazem.
Hypercalcemia can reduce the effectiveness of verapamil in atrial fibrillation. Theoretically, calcium might increase this risk of hypercalcemia and reduce the effectiveness of diltiazem.

Likelihood Probable Evidence D
Levothyroxine (Synthroid, Others)

Calcium seems to reduce the absorption and effectiveness of levothyroxine.
Advise patients to take levothyroxine and calcium supplements at least 4 hours apart. Calcium reduces levothyroxine absorption, probably by forming insoluble complexes. Calcium carbonate supplements reduce effectiveness of levothyroxine in patients with hypothyroidism.

Likelihood Probable Evidence B
Lithium

Theoretically, concomitant use of calcium and lithium may increase this risk of hypercalcemia.
Clinical research suggests that long-term use of lithium may cause hypercalcemia in 10% to 60% of patients. Theoretically, concomitant use of lithium and calcium supplements may further increase this risk.

Likelihood Possible Evidence B
Quinolone Antibiotics

Calcium seems to reduce the absorption of quinolone antibiotics.
Advise patients to take oral quinolones at least 2 hours before or 4-6 hours after calcium supplements or calcium-fortified foods. Taking calcium at the same time as oral quinolones can reduce quinolone absorption. Calcium binds to quinolones in the gut.

Likelihood Probable Evidence B
Raltegravir (Isentress)

Calcium may reduce levels of raltegravir.
Pharmacokinetic research shows that taking a single dose of calcium carbonate 3000 mg along with raltegravir 400 mg twice daily modestly decreases the mean area under the curve of raltegravir, but the decrease does not necessitate a dose adjustment of raltegravir. However, a case of elevated HIV-1 RNA levels and documented resistance to raltegravir has been reported for a patient taking calcium carbonate 1 gram three times daily plus vitamin D3 (cholecalciferol) 400 IU three times daily in combination with raltegravir 400 mg twice daily for 11 months. It is thought that calcium reduced raltegravir levels by chelation, leading to treatment failure.

Likelihood Possible Evidence B
Sotalol (Betapace)

Calcium seems to reduce the absorption of sotalol.
Advise patients to separate doses by at least 2 hours before or 4-6 hours after calcium. Calcium appears to reduce the absorption of sotalol, probably by forming insoluble complexes.

Likelihood Possible Evidence B
Tetracycline Antibiotics

Calcium seems to reduce the absorption of tetracycline antibiotics.
Advise patients to take oral tetracyclines at least 2 hours before, or 4-6 hours after calcium supplements. Taking calcium at the same time as oral tetracyclines can reduce tetracycline absorption. Calcium binds to tetracyclines in the gut.

Likelihood Probable Evidence C
Thiazide Diuretics

Taking calcium along with thiazides might increase the risk of hypercalcemia and renal failure.
Thiazides reduce calcium excretion by the kidneys. Using thiazides along with moderately large amounts of calcium carbonate increases the risk of milk-alkali syndrome (hypercalcemia, metabolic alkalosis, renal failure). Patients may need to have their serum calcium levels and/or parathyroid function monitored regularly.

Likelihood Probable Evidence C
Verapamil (Calan, Others)

Theoretically, calcium may reduce the therapeutic effects of verapamil.
Hypercalcemia can reduce the effectiveness of verapamil in atrial fibrillation. Theoretically, use of calcium supplements may increase this risk of hypercalcemia and reduce the effectiveness of verapamil.

Likelihood Probable Evidence D
Calcium Channel Blockers

Intravenous calcium may decrease the effects of calcium channel blockers; oral calcium is unlikely to have this effect.
Intravenous calcium is used to decrease the effects of calcium channel blockers in the management of overdose. Intravenous calcium gluconate has been used before intravenous verapamil (Isoptin) to prevent or reduce the hypotensive effects without affecting the antiarrhythmic effects. But there is no evidence that dietary or supplemental calcium when taken orally interacts with calcium channel blockers.

Likelihood Unlikely Evidence D
Calcium full monograph & interactions

L-Carnitine-L-Tartrate3 drug types · 19 drugs

Acenocoumarol (Sintrom)

Theoretically, L-carnitine might increase the anticoagulant effects of acenocoumarol.
L-carnitine might enhance the anticoagulant effects of acenocoumarol, an oral anticoagulant similar to warfarin, but shorter-acting. There are at least two case reports of INR elevation with concomitant use. In one case, a 33-year-old male with a previously stable INR had an elevated INR of 4.65 after L-carnitine was started and continued for 10 weeks. INR normalized after discontinuation of the L-carnitine-containing product.

Likelihood Possible Evidence D
Thyroid Hormone

Theoretically, L-carnitine might decrease the effectiveness of thyroid hormone replacement.
L-carnitine appears to act as a peripheral thyroid hormone antagonist by inhibiting entry of thyroid hormone into the nucleus of cells. Taking L-carnitine also seems to diminish some of the symptoms of hyperthyroidism.

Likelihood Probable Evidence B
Warfarin (Coumadin)

Theoretically, L-carnitine might increase the anticoagulant effects of warfarin.
L-carnitine might increase the anticoagulant effects of acenocoumarol, a shorter-acting oral anticoagulant similar to warfarin. There is not enough information to know whether this interaction occurs with L-carnitine and warfarin.

Ergonine Tropical Twist by PEScience: Common Questions

Does Ergonine Tropical Twist by PEScience interact with any medications?
Yes. Based on its ingredients, Ergonine Tropical Twist has a known interaction with 455 medications, including 7 rated major. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Ergonine Tropical Twist 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.
What is L-carnitine and what's it supposed to do?
L-carnitine is an amino acid that helps your body move fatty acids into cells for energy. In this product it's in the form L-carnitine-L-tartrate. It's effective for treating L-carnitine deficiency and possibly effective for high cholesterol and congestive heart failure, though evidence for athletic performance is weaker.
Can I take this while pregnant?
It depends on the ingredient. L-glutamine, L-alanine, choline, and calcium are likely safe in pregnancy, but creatine safety hasn't been established and is best avoided. Asafoetida is likely unsafe in pregnancy. Since this product contains mixed ingredients with different safety profiles, talk with your doctor or pharmacist before taking it while pregnant.
What's the fishy body odor I've heard about?
Both L-carnitine and choline (in the form choline bitartrate) are metabolized in a way that can produce a fish-like body odor, especially at higher doses. This is more common with doses well above typical supplement amounts but is worth knowing about.
Is creatine safe if I have kidney problems?
Creatine is generally well tolerated in healthy adults, but if you have kidney disease or reduced kidney function, it should only be used under medical supervision. Check with your doctor or pharmacist before taking this product.
Will this help my athletic performance?
The evidence is mixed. Creatine is possibly effective for muscle strength and athletic performance. L-carnitine, choline, and glycerol are either possibly ineffective or have insufficient evidence for athletic use. This product contains multiple ingredients, so results would depend on your individual response.
What are the three blends in here that I can't find on the label?
TruGlutamine Blend, Hydroxy-Isocaproic Acid, and PerfomaLean Blend are proprietary formulations — we don't have interaction or safety data available for them. The manufacturer can tell you their exact contents if you contact them directly.
