The bottom line No known interaction

We found no known interaction between Chlorella and Tubocurarine in our sources. Absence of a documented interaction is not the same as proven safety, and does not guarantee one does not exist. Do not start, stop, or change a medication or supplement based on this page; confirm with your pharmacist or doctor first.

Chlorella and Tubocurarine

We checked these two against our interaction database. Here is what we found.

No Known Interaction Found

We did not find a documented interaction between Tubocurarine and Chlorella in our sources. This does not guarantee that the combination is completely free of risk — there is often limited research on supplements and herbal products, especially around drug interactions.

If you decide to take both, the practical routine is simple: add one new thing at a time and note the date you started it. If the combination is going to disagree with you, it usually shows in the first days to a couple of weeks — and a start date turns “I’ve been feeling off” into something a pharmacist can actually work with. Do not stop a prescribed medicine on your own.

Always talk with your pharmacist or doctor before making changes to your medications or supplements, particularly if you take several medications or have an ongoing health condition.

How we checked

Why No Interaction Is Listed for Tubocurarine

Interactions in our licensed database are recorded against drug classes, not just single drug names. Tubocurarine is filed under a single classification — skeletal muscle relaxants. Chlorella has documented interactions with 2 drug classes — the most serious being photosensitizing drugs (moderate) and warfarin (coumadin) (moderate) — and none of Tubocurarine’s classifications are among them.

Classification data comes from our licensed Natural Medicines dataset. A medication can belong to classes beyond those recorded there, so this describes how the check was run — it is not a safety guarantee.

Keep it in perspective

Chlorella Does Interact With Other Medications

What to actually watch for

What Chlorella Itself Has Been Linked To

This is not an interaction — nothing below involves Tubocurarine. It is the side-effect record for Chlorella on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Chlorella, this list is the first place to look. 4 entries are worth acting on rather than waiting out — marked below.

  • Unsteadiness Worth acting on Additional detail

    “Orally, manganese (Mn)-induced parkinsonism has been reported after long-term consumption of chlorella extract. In this case, a patient on maintenance hemodialysis reported gait disturbance, dysarthria, elevated serum and cerebrospinal fluid manganese levels, and abnormal magnetic resonance imaging (MRI) findings of the brain.”

  • A low platelet count Worth acting on Additional detail

    “Orally, chlorella has been linked to one case of thrombocytopenia; however, causality has not been determined. A 49-year-old female living in Turkey presented with thrombocytopenia (a platelet count of 27,000/mm3) after taking chlorella 1080 mg daily for 20 days. Platelet counts had been normal one month earlier, and returned to normal two weeks after discontinuing the chlorella supplement.”

See Every Supplement That Interacts With Tubocurarine

This page covers Chlorella only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Tubocurarine page lists 3 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Procaine (major), Lithium (moderate) and Magnesium (moderate).

By severity: 1 major · 2 moderate.

From our pharmacist’s overview on the Tubocurarine page

“Tubocurarine is not a pill you pick up at the pharmacy; it is a paralyzing agent given during surgery so the anesthesia team can relax your muscles, and that setting is exactly why this short list deserves genuine care. All three flagged ingredients push in the same direction, deepening or stretching out the paralysis the drug causes.”

About Chlorella

What is Chlorella?

Chlorella
  • General nutrition and 'detox' support
  • Immune support
  • Liver and kidney support
  • Antioxidant and anti-inflammatory support
  • Cholesterol and heart health

Chlorella is a nutrient-rich freshwater green algae taken as a supplement for general wellness, immune support, and 'detox.' Some small studies suggest possible benefits for cholesterol, blood pressure, and immune markers, but the overall evidence is limited and not strong. It is generally well tolerated, but quality varies and it should be avoided during pregnancy and breastfeeding unless a doctor approves.

Chlorella vulgaris · Chlorellaceae · Whole dried algae cells · Tablets, capsules, powder, extract, and liquid

An interaction check asks whether these two react with each other — it does not ask whether Chlorella is a good idea for someone in your situation. Here is what our Chlorella record says about it on its own.

Chlorella: dosing

There is no official, standardized dose for chlorella. Studies have used a wide range of amounts, and products differ in strength and quality, so there is no one 'correct' dose.The best approach is to follow the directions on the product label and start with a lower amount to see how your body reacts.

Tubocurarine is filed under 1 classification, and Chlorella has documented interactions with 2 drug classes — none of Tubocurarine's classifications are among them.
