HelloPharmacist Scorecard of Multi Collagen Peptides Unflavored by Codeage

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.

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 3 of its 8 active ingredients.
  • “Multi-Collagen Complex” is a proprietary blend — the label gives one combined amount (10 Gram(s)) without saying how much of each component you get.

This powder contains 8 ingredients, of which several are active. Vitamin C is here to support immune function and collagen production.

The product includes multiple collagen sources — bovine (beef) collagen peptides, fish collagen peptides, and egg shell membrane collagen — all hydrolyzed (broken down) so your body can absorb them more easily. You also get beef and chicken bone broth for additional amino acids and minerals, plus Bacillus coagulans, a live probiotic organism that may help with digestive health.

Hyaluronic acid rounds out the blend for skin hydration support. There are no inactive fillers listed for this product.

Does it work?

Moderate 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
Moderate

Some clinical evidence supports this product's ingredients for its stated purpose, but it isn't conclusive.

Why this rating?
  • The label markets this product for: Collagen and joint skin and bone health.
  • We looked for evidence on: Aging skin, Atopic dermatitis (eczema), Atrophic acne scars, Brittle nails, Cellulite, Dry skin — and 4 related terms.
  • The strongest evidence on file: Collagen Peptides is rated "Possibly Effective" for Aging skin (Natural Medicines).
  • Also on file: Collagen Peptides is rated "Possibly Effective" for Dry skin.
  • Also on file: Vitamin C is rated "Possibly Ineffective" for Fractures.

Vitamin C in this product is effective for preventing vitamin C deficiency and possibly effective for anemia of chronic disease, atrial fibrillation, cataracts, and reducing respiratory infections from heavy exercise. The collagen peptides (from both beef and fish sources) are possibly effective for aging and dry skin, though they appear ineffective for building muscle strength.

Hyaluronic acid is possibly effective for dry eye and venous leg ulcers, though evidence for aging skin and hay fever is insufficient. Bacillus coagulans is possibly effective for constipation and irritable bowel syndrome, but evidence for antibiotic-associated diarrhea, athletic performance, cancer, and fatty liver disease is insufficient.

The bone broths and egg shell membrane collagen — we don't have effectiveness data on file for those.

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 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.

Vitamin C is generally well tolerated at normal doses, but very high intakes can cause stomach cramps, heartburn, diarrhea, nausea, and kidney stones in people prone to them — side effects are more likely above 2 grams daily. The collagen peptides are generally well tolerated, though nausea, upset stomach, diarrhea, and gas are rare.

Hyaluronic acid appears well tolerated orally, though long-term safety of oral supplements isn't fully studied. Bacillus coagulans is generally well tolerated in healthy adults, though serious infections (bacteremia and sepsis) have been reported rarely in severely ill or immunocompromised patients using probiotic products.

If you're pregnant, normal amounts of vitamin C from food and prenatal vitamins are fine, but avoid high-dose supplements unless your doctor advises it. Safety data for collagen peptides and Bacillus coagulans in pregnancy and breastfeeding is limited — talk with your doctor or pharmacist.

We have no pregnancy or lactation safety data on file for hyaluronic acid or the bone broths.

Meds to double-check

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 2 of the 4 matched ingredients can interact with medications — Vitamin C, Bacillus Coagulans.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; cancer treatments.
  • For scale: 386 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.

Double-check this product before you take it with hormonal birth control or hormone replacement therapy (estrogens), blood thinners like warfarin, chemotherapy drugs, thyroid medication (levothyroxine), the HIV drug indinavir, or the antipsychotic fluphenazine — all are moderate-severity interactions with vitamin C. Also separate doses of this product and any antibiotics by a few hours, since the probiotic may be less effective if taken together.

The bottom line

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

This product may help with skin hydration, digestion, and general collagen support, but it's important to check it against any hormonal birth control, blood thinners, chemotherapy, thyroid medication, or antibiotics you're taking. If you're pregnant or breastfeeding, talk with your pharmacist or doctor before starting.

It's generally well tolerated, though very high doses of vitamin C can cause stomach upset.

Vitamin C13 drug types · 207 drugs

Alkylating Agents

Theoretically, antioxidant effects of vitamin C might reduce the effectiveness of alkylating agents.
The use of antioxidants like vitamin C during chemotherapy is controversial. There is concern that antioxidants could reduce the activity of chemotherapy drugs that generate free radicals, such as cyclophosphamide, chlorambucil, carmustine, busulfan, and thiotepa. In contrast, some researchers theorize that antioxidants might make chemotherapy more effective by reducing oxidative stress that could interfere with apoptosis (cell death) of cancer cells. More evidence is needed to determine what effect, if any, antioxidants such as vitamin C have on chemotherapy.

Likelihood Possible Evidence D
Aluminum

Vitamin C can increase the amount of aluminum absorbed from aluminum compounds.
Research in animals and humans shows that vitamin C increases aluminum absorption, theoretically by chelating aluminum and keeping it in solution where it is available for absorption. In people with normal renal function, urinary excretion of aluminum will likely increase, making aluminum retention and toxicity unlikely. Patients with renal failure who take aluminum-containing compounds such as phosphate binders should avoid vitamin C supplements in doses above the recommended dietary allowances.

Likelihood Probable Evidence B
Antitumor Antibiotics

Theoretically, the antioxidant effects of vitamin C might reduce the effectiveness of antitumor antibiotics.
The use of antioxidants like vitamin C during chemotherapy is controversial. There is concern that antioxidants could reduce the activity of chemotherapy drugs which generate free radicals, such as doxorubicin. In contrast, some researchers theorize that antioxidants might make chemotherapy more effective by reducing oxidative stress that could interfere with apoptosis (cell death) of cancer cells. More evidence is needed to determine what effects, if any, antioxidants such as vitamin C have on chemotherapy.

Likelihood Possible Evidence D
Estrogens

Vitamin C might increase blood levels of estrogens.
Increases in plasma estrogen levels of up to 55% occur under some circumstances when vitamin C is taken concurrently with oral contraceptives or hormone replacement therapy, including topical products. It is suggested that vitamin C prevents oxidation of estrogen in the tissues, regenerates oxidized estrogen, and reduces sulfate conjugation of estrogen in the gut wall. When tissue levels of vitamin C are high, these processes are already maximized and supplemental vitamin C does not have any effect on estrogen levels. Increases in plasma estrogen levels may occur when patients who are deficient in vitamin C take supplements. Monitor these patients for estrogen-related side effects.

Likelihood Probable Evidence B
Fluphenazine (Prolixin)

Theoretically, vitamin C might decrease levels of fluphenazine.
In one patient there was a clinically significant decrease in fluphenazine levels when vitamin C (500 mg twice daily) was started. The mechanism is not known, and there is no further data to confirm this interaction.

Likelihood Possible Evidence D
Indinavir (Crixivan)

Vitamin C can modestly reduce indinavir levels.
One pharmacokinetic study shows that taking vitamin C 1 gram orally once daily along with indinavir 800 mg orally three times daily reduces the area under the concentration-time curve of indinavir by 14%. The mechanism of this interaction is unknown, but it is unlikely to be clinically significant in most patients. The effect of higher doses of vitamin C on indinavir levels is unknown.

Likelihood Probable Evidence B
Levothyroxine (Synthroid, Others)

Vitamin C can increase levothyroxine absorption.
Two clinical studies in adults with poorly controlled hypothyroidism show that swallowing levothyroxine with a glass of water containing vitamin C 500-1000 mg in solution reduces thyroid stimulating hormone (TSH) levels and increases thyroxine (T4) levels when compared with taking levothyroxine alone. This suggests that vitamin C increases the oral absorption of levothyroxine, possibly due to a reduction in pH.

Likelihood Probable Evidence B
Warfarin (Coumadin)

High-dose vitamin C might reduce the levels and effectiveness of warfarin.
Vitamin C in high doses may cause diarrhea and possibly reduce warfarin absorption. There are reports of two people who took up to 16 grams daily of vitamin C and had a reduction in prothrombin time. Lower doses of 5-10 grams daily can also reduce warfarin absorption. In many cases, this does not seem to be clinically significant. However, a case of warfarin resistance has been reported for a patient who took vitamin C 500 mg twice daily. Cessation of vitamin C supplementation resulted in a rapid increase in international normalized ratio (INR). Tell patients taking warfarin to avoid taking vitamin C in excessively high doses (greater than 10 grams daily). Lower doses may be safe, but the anticoagulation activity of warfarin should be monitored. Patients who are stabilized on warfarin while taking vitamin C should avoid adjusting vitamin C dosage to prevent the possibility of warfarin resistance.

Likelihood Possible Evidence D
Acetaminophen (Tylenol, Others)

High-dose vitamin C might slightly prolong the clearance of acetaminophen.
A small pharmacokinetic study in healthy volunteers shows that taking high-dose vitamin C (3 grams) 1.5 hours after taking acetaminophen 1 gram slightly increases the apparent half-life of acetaminophen from around 2.3 hours to 3.1 hours. Ascorbic acid competitively inhibits sulfate conjugation of acetaminophen. However, to compensate, elimination of acetaminophen glucuronide and unconjugated acetaminophen increases. This effect is not likely to be clinically significant.

Likelihood Probable Evidence B
Aspirin

Acidification of the urine by vitamin C might increase aspirin levels.
It has been suggested that acidification of the urine by vitamin C could increase reabsorption of salicylates by the renal tubules, and increase plasma salicylate levels. However, short-term use of up to 6 grams daily of vitamin C does not seem to affect urinary pH or salicylate excretion, suggesting this interaction is not clinically significant.

Likelihood Possible Evidence B
Choline Magnesium Trisalicylate (Trilisate)

Acidification of the urine by vitamin C might increase choline magnesium trisalicylate levels.
It has been suggested that acidification of the urine by vitamin C could increase reabsorption of salicylates by the renal tubules, and increase plasma salicylate levels. However, short-term use of up to 6 grams daily of vitamin C does not seem to affect urinary pH or salicylate excretion, suggesting this interaction probably is not clinically significant.

Likelihood Possible Evidence B
Niacin

Vitamin C might decrease the beneficial effects of niacin on high-density lipoprotein (HDL) cholesterol levels.
A combination of niacin and simvastatin (Zocor) effectively raises HDL cholesterol levels in patients with coronary disease and low HDL levels. Clinical research shows that taking a combination of antioxidants (vitamin C, vitamin E, beta-carotene, and selenium) along with niacin and simvastatin (Zocor) attenuates this rise in HDL, specifically the HDL-2 and apolipoprotein A1 fractions, by more than 50% in patients with coronary disease. It is not known whether this adverse effect is due to a single antioxidant such as vitamin C, or to the combination. It also is not known whether it will occur in other patient populations.

Likelihood Possible Evidence A
Salsalate (Disalcid)

Acidification of the urine by vitamin C might increase salsalate levels.
It has been suggested that acidification of the urine by vitamin C could increase reabsorption of salicylates by the renal tubules, and increase plasma salicylate levels. However, short-term use of up to 6 grams/day vitamin C does not seem to affect urinary pH or salicylate excretion, suggesting this interaction probably is not clinically significant.

Likelihood Possible Evidence B
Vitamin C full monograph & interactions

B. coagulans1 drug type · 182 drugs

Antibiotic Drugs

Theoretically, taking antibiotics with Bacillus coagulans might decrease the effectiveness of B. coagulans.
B. coagulans preparations usually contain live and active organisms. Therefore, simultaneously taking antibiotics might kill a significant number of the organisms. Tell patients to separate administration of antibiotics and B. coagulans preparations by at least two hours.

Multi Collagen Peptides Unflavored by Codeage: Common Questions

Does Multi Collagen Peptides Unflavored by Codeage interact with any medications?
Yes. Based on its ingredients, Multi Collagen Peptides Unflavored has a known interaction with 386 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Multi Collagen Peptides Unflavored contains 8 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.
Can I take this if I'm on birth control pills?
You should talk with your pharmacist or doctor first. Vitamin C in this product can increase blood levels of hormonal birth control by up to 55% in some cases, which could change how well it works or increase side effects. They can help you figure out if it's safe for you or if you need to adjust timing.
Does this actually help with wrinkles or skin aging?
The collagen peptides in this product are possibly effective for aging skin, so there's some evidence they may help — but it's not definitive. Results vary by person, and you'd likely need to take it consistently over time to notice a difference.
What's hyaluronic acid doing in here?
Hyaluronic acid is a compound that holds water and supports skin hydration. It's possibly effective for dry eye and venous leg ulcers, so it fits with the skin and hydration support theme of the product.
Is the probiotic (Bacillus coagulans) safe to take with antibiotics?
Antibiotics can kill the live organisms in the probiotic, making it less effective. If you're on antibiotics, separate the doses by a few hours — take one in the morning and the other in the evening — rather than at the same time.
Can I take this while breastfeeding?
Safety data for the collagen peptides and probiotic during breastfeeding is limited. Vitamin C in normal amounts is generally okay, but talk with your doctor or pharmacist to make sure it's right for you before you start.
Will this cause stomach upset?
Nausea, upset stomach, diarrhea, and gas are rare with collagen peptides, and the probiotic is generally well tolerated. Very high doses of vitamin C can cause cramping and diarrhea, but the amount in this product is unlikely to cause that unless you're taking it alongside other high-dose vitamin C sources.
