Primal Greens is a legitimate 8 g greens powder (53/100), so its complaints are mostly about disclosure and billing rather than safety. Everything here is dated.

The complaint themes

01Proprietary blends. The 50-plus ingredients sit in proprietary blends with no individual amounts, so you can’t verify doses — the main knock in our review.
02Unnamed testing. A “third-party tested” claim with no named program (no NSF) and no published COA — a claim, not a credential.
03Subscription billing. Like most DTC greens, complaints cluster on auto-ship and cancellation; check the current BBB profile before enrolling.

Side effects and safety notes

As a greens powder, Primal Greens has a mild side-effect profile: the most common reports are mild bloating or digestive changes in the first few days, typical when adding greens and probiotics, usually settling with time or a smaller starting scoop. It’s a broad multi-plant blend, so anyone with specific plant allergies should scan the ingredient list, and people who are pregnant, nursing, on medication (greens can be high in vitamin K, relevant for blood thinners) or managing a health condition should check with a clinician first. No named testing means contaminant screening isn’t independently verified — a transparency gap more than a known hazard.

Frequently asked questions

Does Primal Greens have side effects?

The profile is mild — the most common reports are bloating or digestive changes in the first few days, usual for greens and probiotics, which typically settle. Greens can be high in vitamin K (relevant for blood thinners), so check with your doctor if that applies.

What are the main complaints about Primal Greens?

The proprietary blends that hide every ingredient amount, a “third-party tested” claim that names no certification program, and subscription billing/cancellation friction.

Is Primal Greens third-party tested?

The brand claims it is, but names no program (like NSF) and publishes no certificate of analysis — a claim rather than a verifiable credential.
