What’s inside

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 4 of its 4 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

This product has 4 active ingredients. Calcium supports bone health and is used to treat low calcium levels, heartburn, and high potassium; it's the main workhorse here.

DIM (diindolylmethane) is a compound from cruciferous vegetables like broccoli. Sodium copper chlorophyllin is a semi-synthetic form of chlorophyll, the green pigment in plants.

Calcium D-glucarate is a compound derived from calcium and glucaric acid. The capsules also contain inactive ingredients — hypromellose, microcrystalline cellulose, stearic acid, and silicon dioxide — that help hold the formula together.

Strong 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
Strong

Clinical evidence supports at least one of this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: healthy hormone metabolism and detoxification.
  • We looked for evidence on: Acne, Dysmenorrhea, Mastalgia, Premenstrual syndrome (PMS), Prostate cancer, Benign prostatic hyperplasia (BPH) — and 3 related terms.
  • The strongest evidence on file: Calcium is rated "Likely Effective" for Premenstrual syndrome (PMS) (Natural Medicines).
  • Also on file: Calcium D-glucarate is rated "Insufficient Reliable Evidence To Rate" for Prostate cancer.
  • Also on file: Chlorophyllin is rated "Insufficient Reliable Evidence To Rate" for Acne, Cancer.

Calcium in this product is rated Likely Effective for osteoporosis prevention and Effective for bone health, treating low calcium levels, heartburn (dyspepsia), kidney failure, and elevated potassium (hyperkalemia). The other three ingredients — DIM, sodium copper chlorophyllin, and calcium D-glucarate — all lack established evidence.

The data we hold shows insufficient reliable evidence to rate DIM for prostate health, breast concerns, colorectal or cervical health, or breast pain. Chlorophyllin is possibly ineffective for urinary odor and has insufficient evidence for acne, cancer prevention, constipation, gas, or low white blood cell counts.

Calcium D-glucarate similarly lacks established evidence for breast, prostate, or colorectal cancer. If you're taking this product mainly for one of these latter purposes, the evidence doesn't yet support that use.

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 3 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.

Calcium is generally well tolerated at recommended doses, though high amounts can cause problems. Common side effects when taken by mouth are belching, constipation, diarrhea, gas, and upset stomach.

Rare serious concerns include kidney stones and a condition called calciphylaxis. There's also some concern that very high calcium intake — over 1500 to 2000 mg daily — might increase prostate cancer risk and possibly cardiovascular risk, though research on this is mixed and debated.

DIM is generally well tolerated short-term, though long-term safety isn't firmly established. Common side effects include diarrhea, gas, headache, nausea, rash, and vomiting; a rare serious reaction (DRESS syndrome) has been reported.

One case linked DIM to stroke, but the patient had multiple risk factors, so it's unclear whether DIM was responsible. Sodium copper chlorophyllin is generally well tolerated short-term but may cause photosensitization and pseudoporphyria (a blistering condition mimicking porphyria) in rare cases.

Calcium D-glucarate appears generally tolerated in small studies, though long-term human safety data are limited. For pregnancy: calcium is considered likely safe at recommended amounts; DIM is likely safe; but sodium copper chlorophyllin and calcium D-glucarate lack enough safety information and should be avoided in pregnancy.

For breastfeeding: calcium and DIM are acceptable at recommended amounts; chlorophyllin and calcium D-glucarate should be avoided due to insufficient safety data.

The bottom line

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

This product's calcium content makes it useful if you need supplemental calcium for bone health or related conditions, but it carries significant interactions — especially with HIV medications and the antibiotic ceftriaxone, and with thyroid and heart rhythm drugs. DIM, chlorophyllin, and calcium D-glucarate lack proven effectiveness for most uses they're marketed for.

Check with your doctor or pharmacist before starting, particularly if you take any prescription medications.

Sodium Copper Chlorophyllin1 drug type · 335 drugs

Photosensitizing Drugs

Theoretically, concomitant use of chlorophyllin with photosensitizing drugs may have additive effects.
Chlorophyllin is a semi-synthetic derivative of chlorophyll. Chlorophyll has been reported to cause photosensitization. Orally, chlorophyll has also been associated with the development of pseudoporphyria in multiple case reports.

Likelihood Probable Evidence B

DIM3 drug types · 269 drugs

Diuretic Drugs

Theoretically, diindolylmethane might increase the risk of hyponatremia if used with sodium-depleting diuretics.
Large doses of diindolylmethane (600 mg daily) have been associated with two cases of asymptomatic hyponatremia in clinical research.

Likelihood Possible Evidence B
Estrogens

Theoretically, diindolylmethane might increase or decrease the effects of estrogens.
Diindolylmethane might have mild estrogenic or antiestrogenic effects. Theoretically, large amounts of diindolylmethane might interfere with hormone replacement therapy.

Likelihood Possible Evidence D
Cytochrome P450 1A2 (Cyp1A2) Substrates

Theoretically, diindolylmethane might lower serum levels of CYP1A2 substrates.
In vitro evidence suggests that diindolylmethane can induce CYP1A2. Theoretically, it might increase metabolism of CYP1A2 substrates and lower serum concentrations. This interaction has not been reported in humans.

Likelihood Unlikely Evidence D

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 D-Glucarate Tetrahydrate3 drug types · 126 drugs

Alcohol (Ethanol)

Theoretically, concomitant use with alcohol might decrease calcium D-glucarate activity.
There is some evidence that urinary excretion of calcium D-glucarate metabolites increases in people consuming alcohol.

Likelihood Possible Evidence B
Glucuronidated Drugs

Theoretically, calcium D-glucarate might increase the clearance of drugs that undergo glucuronidation.
The calcium D-glucarate metabolite, D-glucaro-1,4-lactone, inhibits the enzyme beta-glucuronidase, reducing deconjugation of glucuronides in the intestine and thereby reducing reabsorption of the drugs.

Likelihood Possible Evidence B
Kanamycin

Theoretically, calcium D-glucarate may reduce plasma levels of kanamycin.
Calcium D-glucarate may increase the rate of kanamycin elimination, which may decrease its clinical and adverse effects.

DIM 200 plus CDG 100 by Protocol For Life Balance: Common Questions

Does DIM 200 plus CDG 100 by Protocol For Life Balance interact with any medications?
Yes. Based on its ingredients, DIM 200 plus CDG 100 has a known interaction with 615 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?
DIM 200 plus CDG 100 contains 4 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 DIM and why is it in this product?
DIM is diindolylmethane, a compound naturally found in cruciferous vegetables like broccoli and cabbage. Manufacturers include it in supplements hoping it might support hormone balance and prostate or breast health, but the evidence for these uses isn't established in our data.
Can I take this if I'm pregnant or breastfeeding?
Calcium and DIM are considered likely safe in pregnancy and breastfeeding at recommended amounts. However, the sodium copper chlorophyllin and calcium D-glucarate ingredients lack enough safety data, so they should be avoided while pregnant or nursing — talk with your doctor or pharmacist about whether this product is right for you during these times.
What are the most common side effects?
From calcium: belching, constipation, diarrhea, gas, and stomach upset. From DIM: diarrhea, gas, headache, nausea, and rash. These are usually mild, but if they're bothersome, let your doctor or pharmacist know.
Does this product actually help with cancer prevention?
Not according to the evidence we hold. DIM, chlorophyllin, and calcium D-glucarate all lack reliable evidence for cancer prevention, so it's not accurate to market this as a cancer-preventive supplement.
Why does this interact with so many medications?
The calcium in this product binds to certain drugs in your stomach and intestines, preventing your body from absorbing them fully — that's why it needs to be spaced hours away from thyroid and heart drugs. DIM changes how your liver processes some medications, and calcium D-glucarate affects how your body clears drugs through a specific liver pathway. With four ingredients, there are many opportunities for overlap with medications you might be taking.
Is it safe to take this long-term?
Calcium at recommended doses is fine long-term. However, long-term safety data for DIM, sodium copper chlorophyllin, and calcium D-glucarate are limited, so we don't have solid information on what happens if you take them for months or years. Talk with your pharmacist or doctor about how long you plan to use it.
