HelloPharmacist Scorecard of Proline Rich Polypeptides With Colostrum Plus by Symbiotics

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 3 active ingredients.
  • “Colostrum Plus(R)” is listed as a grouped ingredient — the label gives one combined amount (910 mg) without saying how much of each component you get.

This product contains 3 active ingredients. Bovine Colostrum is the main one — it's the nutrient-rich fluid that comes from a cow's udder after birth.

The other two, Phospholipids and Proline-rich Polypeptides, are compounds sourced from colostrum as well. The capsule itself is made from gelatin.

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: immune support and gut health.
  • We looked for evidence on: Exercise-induced respiratory infections, HIV/AIDS-related diarrhea, Influenza, Rotaviral diarrhea, Sepsis, Shigellosis — and 4 related terms.
  • The strongest evidence on file: Bovine Colostrum is rated "Possibly Effective" for HIV/AIDS-related diarrhea (Natural Medicines).
  • Also on file: Bovine Colostrum is rated "Possibly Effective" for Exercise-induced respiratory infections, Rotaviral diarrhea.
  • Also on file: Bovine Colostrum is rated "Possibly Ineffective" for Short bowel syndrome, Sepsis.

Bovine Colostrum is rated possibly effective for HIV/AIDS-related diarrhea, rotaviral diarrhea, and exercise-induced respiratory infections. It's rated possibly ineffective for necrotizing enterocolitis (a serious intestinal condition in newborns).

We don't have effectiveness data in our records for the other two active ingredients in this product.

The evidence, ingredient by ingredient Bovine Colostrum

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 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Bovine Colostrum is generally well tolerated in most adults, but if you have a milk or dairy allergy, you should avoid it. The safety data during pregnancy isn't strong enough to say it's safe, so it's best to avoid it unless your doctor approves.

During breastfeeding, safety hasn't been well studied — use caution and check with your provider. In clinical trials, a small number of patients reported mild bloating, nausea, diarrhea, and stomach upset at about the same rate as those taking a whey-based control.

One person with HIV-related cryptosporidiosis had nausea and vomiting. Rarely, it's been linked to elevated liver function tests and a drop in blood cell count in HIV patients being treated for infectious diarrhea.

Side effects, ingredient by ingredient Bovine Colostrum

Meds to double-check

No known interactions
Known Interaction Concern · database check
No known interactions

No medication interactions are currently documented for the matched ingredients — that isn't a guarantee none exist.

Why this rating?
  • None of the 1 matched ingredient has a documented medication interaction on file.

No interactions are documented in our data for the ingredients we could check. That said, we don't hold interaction data for Phospholipids or Proline-rich Polypeptides, so check your exact medications with the search tool on this page to be thorough.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with some supporting evidence for its stated purpose. No medication interactions are currently documented, and safety information is well characterized.

This product may be worth considering if you're dealing with HIV/AIDS-related diarrhea, rotaviral diarrhea, or want immune support around exercise. If you have a dairy allergy, skip it.

Pregnant women should talk to their doctor first. Run your medications through the checker before you start — we couldn't verify all the ingredients.

Newborns who breastfeed get a head start in immunity through the PRP’s and other immune factors they get from their mother’s Colostrum. This is often called "Passive Immunity."

PRPs are extracted from bovine colostrum – dairy cows are the most abundant source of raw colostrum available today. The PRPs in bovine colostrum are the same as all other mammals and can be used as a health supplement for all other mammal species, including humans.

The potency of each PRP Powder batch is analytically validated using a HPLC/UV/MS system.

We only use the first 2 milkings to guarantee potency and quality.
