Regu-Cycle Ingredients & Drug Interactions
by R-U-Ved
What is this page for?
First and foremost: checking Regu-Cycle against your medications. The heart of this page is the interaction checker and the full interaction report — how this product’s ingredients may interact with prescription and over-the-counter medicines you may be taking.
Around that, we add a pharmacist’s high-level view of the product as a whole — what’s inside, the evidence for its stated use, how transparent the label is, and what safety data exists — so you can see the full picture in one place. It’s educational information from our licensed clinical databases and the clinical staff at HelloPharmacist — not medical advice — and we don’t sell or endorse products. Our editorial policy

HelloPharmacist Scorecard of Regu-Cycle by R-U-Ved
Four independent checks of what is known — a summary of the available information, not a grade of the product itself.
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
The stated purpose hasn't been mapped to our evidence data yet.
Why this rating?
- We haven't mapped this product's purpose to our evidence data yet — it'll be graded on the next content refresh.
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 3 of its 6 active ingredients.
- “In a base of the following extracts” is listed as a grouped ingredient — the label gives one combined amount (230 mg) without saying how much of each component you get.
At least one ingredient has a documented Major-severity interaction. Check your medications for a personalized result.
Why this rating?
- 4 of the 4 matched ingredients can interact with medications — Bamboo, Aloe, Gotu Kola, Vitamin B6.
- The most serious interaction on file is rated Major.
- Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; diabetes medications; heart-rhythm medications; Parkinson's medications.
- For scale: 979 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.
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 4 of the 4 matched ingredients.
- Pregnancy & breastfeeding safety ratings cover 4 of 4.
- General safety write-ups exist for 4 of 4.
- Remember: this measures how much safety information exists. Thin data is not the same as being safe.
HelloPharmacist summaryPartially disclosed formula with no assessable stated purpose. Major medication interactions have been identified, and safety information is well characterized.

For each ingredient in Regu-Cycle 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.
Gotu Kola
Cns Depressants
Theoretically, taking gotu kola might increase the sedative effects of CNS depressants.
In vitro research suggests that gotu kola may have sedative effects via binding of GABA receptors.
Hepatotoxic Drugs
Theoretically, taking gotu kola with hepatotoxic drugs might have additive adverse effects.
There are at least four case reports of hepatotoxicity associated with the use of gotu kola. However, more information is needed to determine if gotu kola was the causative factor in these cases.
Aloe
Digoxin (Lanoxin)
Theoretically, aloe latex might increase the risk of adverse effects when taken with cardiac glycosides.
Overuse of aloe latex can increase the risk of adverse effects from cardiac glycoside drugs, such as digoxin, due to potassium depletion. Overuse of aloe, along with cardiac glycoside drugs, can increase the risk of toxicity.
Anticoagulant/Antiplatelet Drugs
Theoretically, aloe gel might increase the risk of bleeding when taken with anticoagulant or antiplatelet drugs.
In vitro research shows that aloe gel can inhibit platelet aggregation. This inhibition was greater than that seen with celecoxib, but less than that seen with aspirin.
Antidiabetes Drugs
Aloe might increase the risk of hypoglycemia when taken with antidiabetes drugs.
Preliminary clinical research suggests aloe gel might lower blood glucose levels and have additive effects when used with antidiabetes drugs. Monitor blood glucose levels closely.
Diuretic Drugs
Theoretically, aloe latex might increase the risk of hypokalemia when taken with diuretic drugs.
Overuse of aloe latex might compound diuretic-induced potassium loss, increasing the risk of hypokalemia.
Stimulant Laxatives
Theoretically, aloe latex might increase the risk for fluid and electrolyte loss when taken with stimulant laxatives.
Due to cathartic laxative effects of aloe latex, concomitant use with other stimulant laxatives might compound fluid and electrolyte loss.
Warfarin (Coumadin)
Theoretically, aloe latex might increase the risk of bleeding when taken with warfarin.
Aloe latex has stimulant laxative effects. In some people aloe latex can cause diarrhea. Diarrhea can increase the effects of warfarin, increase international normalized ratio (INR), and increase the risk of bleeding. Advise patients who take warfarin not to take excessive amounts of aloe vera.
Cytochrome P450 1A2 (Cyp1A2) Substrates
Theoretically, aloe might decrease the levels and clinical effects of CYP1A2 substrates.
In vitro research shows that aloe extract induces CYP1A2 enzymes.
Vitamin B-6
Amiodarone (Cordarone)
Theoretically, vitamin B6 might increase the photosensitivity caused by amiodarone.
Despite initial case reports suggesting that pyridoxine may have a protective effect against amiodarone-induced photosensitivity, preliminary clinical research suggests that pyridoxine may actually exacerbate this adverse effect.
Antihypertensive Drugs
Theoretically, vitamin B6 may have additive effects when used with antihypertensive drugs.
Research in hypertensive rats shows that vitamin B6 can decrease systolic blood pressure. Similarly, clinical research in patients with hypertension shows that taking high doses of vitamin B6 may reduce systolic and diastolic blood pressure, possibly by reducing plasma levels of epinephrine and norepinephrine.
Phenobarbital (Luminal)
High doses of vitamin B6 may reduce the levels and clinical effects of phenobarbital.
Preliminary clinical evidence suggests that vitamin B6 200 mg daily can reduce plasma levels of phenobarbital, possibly by increasing metabolism. It is not known whether lower doses have any effect. Advise people taking phenobarbital to avoid high doses of vitamin B6.
Phenytoin (Dilantin)
High doses of vitamin B6 may reduce the levels and clinical effects of phenytoin.
Preliminary clinical evidence suggests that vitamin B6 200 mg daily can reduce plasma levels of phenytoin, possibly by increasing metabolism. It is not known whether lower doses have any effect. Advise people taking phenytoin to avoid high doses of vitamin B6.
Levodopa
Vitamin B6 may increase the metabolism of levodopa when taken alone, but not when taken in conjunction with carbidopa.
Vitamin B6 (pyridoxine) enhances the metabolism of levodopa, reducing its clinical effects. However, this interaction does not occur when carbidopa is used concurrently with levodopa (Sinemet). Therefore, it is not likely to be a problem in most people.
Bamboo
Antithyroid Drugs
Theoretically, long-term bamboo use might increase the effects and adverse effects of antithyroid drugs, possibly leading to hypothyroidism.
Animal research suggests that long-term consumption of bamboo shoot can decrease thyroid peroxidase activity, as well as levels of thyroxine (T4) and triiodothyronine (T3). This effect has not yet been reported in humans.
