HelloPharmacist Scorecard of Bio-Gro Chocolate Ice Cream by iSatori

Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.

From our pharmacy team — supplement deep dive

What’s inside

Low disclosure
Ingredient Transparency · database check
Low

Most active ingredients don't disclose an individual amount — you can't tell how much of each you're getting.

Why this rating?
  • The label discloses an exact amount for 1 of its 6 active ingredients.
  • “Custom Engineered Bio-Pro Bio-Active Peptides” is listed as a grouped ingredient — the label gives one combined amount (1.50 Gram(s)) without saying how much of each component you get.

Bio-Gro Chocolate Ice Cream contains 6 active ingredients. The most notable is calcium, a mineral essential for bone health and a range of body functions.

The product also includes lactoferrin, an iron-binding protein found naturally in milk; growth factors; immunoglobulins (antibodies); fibroblasts growth factor; and proline-rich peptides, which are small protein building blocks. The product also contains several inactive ingredients — sucralose (a sweetener), natural and artificial flavors, medium chain triglycerides (a type of fat), and sunflower lecithin — that help give it its ice cream texture and taste.

Does it work?

Insufficient 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
Insufficient

There isn't enough reliable clinical evidence to rate this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: Build muscle, recover faster and increase strength.
  • We looked for evidence on: Athletic performance, Exercise-induced muscle damage, Wound healing, Muscle hypertrophy, Protein synthesis, Athletic recovery.
  • The closest evidence on file: Calcium is rated "Insufficient Reliable Evidence To Rate" for Exercise-induced muscle damage (Natural Medicines).
  • Also on file: Proline is rated "Insufficient Reliable Evidence To Rate" for Athletic performance, Wound healing.

Calcium in this product is effective for preventing and treating low blood calcium (hypopenia), bone loss (osteoporosis), kidney disease, high potassium (hyperkalemia), and upset stomach (dyspepsia). It's also likely effective for osteoporosis prevention and treatment.

Lactoferrin shows possibly effective evidence for sepsis and pregnancy-related iron deficiency, but the evidence suggests it's likely ineffective for reducing death in newborns and premature infants or for preventing serious intestinal infection (necrotizing enterocolitis) in preemies. For proline-rich peptides and growth factors, the evidence we hold is insufficient to rate their effectiveness for athletic performance, bone density, fractures, and wound healing.

The evidence, ingredient by ingredient Calcium Lactoferrin Proline

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 2 of the 3 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 3 of 3.
  • General safety write-ups exist for 3 of 3.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Calcium is generally well tolerated when you stick to recommended doses, though high amounts can cause problems. Common side effects from oral calcium are belching, constipation, diarrhea, gas, and stomach upset.

Rare serious concerns from case reports include a condition affecting blood vessels and skin (calciphylaxis) and kidney stones. There's also some concern that very high calcium intake — over 1,500 to 2,000 mg daily — may be linked to increased prostate cancer risk and possibly to heart disease, though research on this is mixed.

Lactoferrin is generally well tolerated short-term, but long-term safety data are limited. At higher doses (7.2 grams daily), it may cause constipation, diarrhea, fatigue, and loss of appetite.

During pregnancy, calcium at recommended amounts is considered likely safe and important for your baby's development. Lactoferrin safety in pregnancy is not fully established, so use it only under medical supervision.

For breastfeeding, calcium needs can be met through recommended amounts, and lactoferrin occurs naturally in breast milk, though supplement safety while breastfeeding hasn't been well studied. We have no pregnancy or breastfeeding data on file for proline-rich peptides, so talk with your doctor or pharmacist about whether it's right for you.

Meds to double-check

Major interaction found
Known Interaction Concern · database check
Major identified

At least one ingredient has a documented Major-severity interaction. Check your medications for a personalized result.

Why this rating?
  • 1 of the 3 matched ingredients can interact with medications — Calcium.
  • The most serious interaction on file is rated Major.
  • Some involve high-stakes drug classes: heart-rhythm medications; lithium.
  • For scale: 168 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.

Before taking this product, double-check with your pharmacist if you take HIV integrase inhibitors (dolutegravir or elvitegravir), ceftriaxone by IV, levothyroxine for low thyroid, sotalol for heart rhythm, raltegravir for HIV, calcipotriene cream for psoriasis, or diltiazem for blood pressure or heart rhythm. The calcium in this product can reduce how well some of these work or cause dangerous interactions.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with insufficient evidence for its stated purpose. Major medication interactions have been identified, and safety information is well characterized.

This product may be worth considering if you're looking for a calcium supplement with added protein and growth-support compounds, especially for bone health. However, if you take HIV medications (integrase inhibitors like dolutegravir or elvitegravir), thyroid medication, heart rhythm drugs, or receive ceftriaxone by IV, you need to check with your pharmacist first — the calcium here can significantly interfere with how these drugs work.

Talk to your pharmacist before starting, especially if you're pregnant, breastfeeding, or have a history of kidney stones or high calcium levels.

Each ingredient & the kinds of drugs it affects

For each ingredient in Bio-Gro Chocolate Ice Cream with known interactions, here are the types of medications it 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.

Bio-Gro Chocolate Ice Cream by iSatori: Common Questions

Does Bio-Gro Chocolate Ice Cream by iSatori interact with any medications?
Yes. Based on its ingredients, Bio-Gro Chocolate Ice Cream has a known interaction with 168 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?
Bio-Gro Chocolate Ice Cream 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.
Is the calcium in this product strong enough to help with bone loss?
Yes. Calcium is likely effective for osteoporosis, and it's also effective for preventing and treating low blood calcium. For the best results, make sure you're getting enough vitamin D and doing weight-bearing exercise, and talk with your doctor about your overall bone health plan.
Can I take this while I'm pregnant or breastfeeding?
Calcium at recommended amounts is important during pregnancy and considered likely safe. For breastfeeding, calcium needs can be met through recommended doses. However, we don't have enough data on the other active ingredients — lactoferrin, growth factors, and peptides — during pregnancy or breastfeeding, so talk with your doctor or pharmacist for personalized advice.
What are the side effects I might notice?
The most common side effects from the calcium are belching, constipation, diarrhea, gas, and stomach upset. Lactoferrin at typical doses is usually well tolerated, though some people report diarrhea or constipation. At higher doses, lactoferrin may cause fatigue and loss of appetite. Serious side effects are rare.
Does this product have any fillers?
It contains inactive ingredients that help with taste and texture: sucralose, natural and artificial flavors, medium chain triglycerides, and sunflower lecithin. If you're trying to avoid certain additives, check the full ingredient list on the package.
Is there enough research behind the growth factors and peptides in this product?
The evidence for proline-rich peptides isn't established yet — we don't have reliable data on whether they help with bone health, athletic performance, fractures, or wound healing. Growth factors and fibroblast-GF also lack strong evidence in our data. The main ingredient with solid research is the calcium.
