Understanding the interactions, benefits, and safety of combining these two powerful supplements.

Calcium Citrate
+
Chlorella

Short answer

We found no documented interaction between Calcium and Chlorella in the sources below. That isn't proof the combination is right for you: check each one's cautions, and ask your pharmacist if you take medication.

Calcium

What it is: The body's most abundant mineral; it builds bones and teeth and helps muscles, nerves and blood vessels work.

What the research says: Calcium supports bone health, especially when diet falls short. Vitamin D helps the body absorb it.

Cautions

  • Upper limit from all sources: 2,500 mg a day for adults 19 to 50, and 2,000 mg from age 51.
  • Some research links very high intakes to heart disease and prostate cancer risk.

Medicines to check

  • Levothyroxine (thyroid medicine): keep doses apart
  • Quinolone antibiotics: keep at least 2 hours apart
  • Dolutegravir (HIV medicine) and lithium

Chlorella

What it is: A green freshwater alga sold as a supplement.

What the research says: A review of 10 trials found modest drops in total and LDL cholesterol. Only 2 of those trials checked what the supplements actually contained.

Cautions

  • That review didn't assess safety, and we didn't find a reliable safety review.

Medicines to check

  • Talk to your clinician if you take any medicine

Educational information only, not medical advice. This reflects general ingredient overlap, not a personalized safety review. Always check with your doctor or pharmacist before combining supplements, especially if you take medication, are pregnant or nursing, or manage a health condition. These statements have not been evaluated by the FDA.

Stop Guessing Your Dosages.

Balancing dosages across multiple different bottles is risky, inefficient, and expensive. Taking too much of one can blunt the absorption of the other.

Holitro completely solves this. We combine synergistic ingredients into one perfectly dosed daily pack, scientifically formulated for maximum absorption.
