Bloom Colostrum & Collagen is a widely marketed product (45/100) whose complaints are less about safety than about what it is and how the company responds to problems. Everything here is dated.

The complaint themes

01Mostly collagen, sold as colostrum. Each 4.7 g scoop is 3.7 g collagen and just 1 g colostrum — 79% collagen — so buyers expecting a colostrum product get a collagen one with a garnish. Our cost breakdown shows the per-gram effect.
02BBB record. An F rating with unanswered complaints at the Better Business Bureau — a customer-service and responsiveness pattern worth checking before you subscribe. Verify the current profile.
03Unspecified testing. A “third-party tested” claim with no named standard or published COA — a claim, not a credential.

Side effects and safety notes

The formula itself has a mild side-effect profile: colostrum and collagen are both generally well tolerated, with occasional mild digestive effects when starting. The important note is the allergen one — it contains dairy (colostrum), so anyone with a dairy allergy should avoid it, and lactose-sensitive users may notice effects. The product is sweetened and flavored (e.g., strawberries and cream), which some find pleasant and others too sweet. The weightier considerations here are the naming and the BBB responsiveness record above, not acute safety. Pregnant, nursing or immunocompromised users should check with a clinician.

Frequently asked questions

Does Bloom Colostrum & Collagen have side effects?

The formula is mild — occasional digestive effects when starting. The key note is that it contains dairy (colostrum), so avoid it with a dairy allergy, and lactose-sensitive users may notice effects. It’s sweetened and flavored.

What are the main complaints about Bloom Colostrum & Collagen?

That it’s 79% collagen and only 1 g colostrum despite the colostrum-forward marketing, an F rating with unanswered complaints at the BBB, and an unspecified “third-party tested” claim.

Is Bloom Colostrum & Collagen actually colostrum?

Only partly — about 1 g of colostrum per 4.7 g scoop (roughly 21%), with the rest collagen peptides and a probiotic. If you want a colostrum supplement, dedicated products deliver 2–3 g of colostrum per serving.
