Relief Factor’s side-effect profile is genuinely mild; the “harm” people report is almost entirely financial. This page separates the two: the recurring billing complaints, the modest physical effects, and the evidence gaps behind the formula. Everything is dated, and we flag what’s a documented pattern versus an individual report.
The complaint themes
Side effects and safety notes
Physically, Relief Factor is low-risk. The most common notes are fish-oil related — fishy burps or aftertaste and mild digestive upset — usually manageable by taking the packets with food. The turmeric (curcumin) component can interact with warfarin and other blood thinners and may add to bleeding risk, so anyone on those medications should check with a doctor first. As with any supplement, people who are pregnant, nursing, or managing a health condition should consult a clinician. Worth noting: the label claims “3rd-party tested” but names no certifier, so that reassurance can’t be verified. The honest summary is that the real risk here is to your wallet, not your body.
| Surprise auto-ship (~$84.95/mo) | Financial | Dominant complaint |
|---|---|---|
| Cancellation friction | Financial | Common, tied to auto-ship |
| Fishy burps / mild GI | Physical | Mild, take with food |
| Turmeric + blood thinners | Physical | Ask a doctor first |
| Unverifiable benefit | Evidence | Underdosed, no formula trial |
Put simply: the physical downside is small and manageable, but the billing model is where most buyers get burned. If you’re weighing whether to enroll, the cost breakdown shows exactly what the trial converts to, and the alternatives page covers options that skip the auto-ship entirely.
Frequently asked questions
Does Relief Factor have side effects?
For most people they’re mild and fish-oil related — fishy burps or aftertaste and minor digestive upset, usually eased by taking it with food. The turmeric can interact with blood thinners, so check with your doctor if you take one. Physically it’s low-risk.
What is the most common Relief Factor complaint?
Billing. The $19.95 trial enrolls you in a subscription that jumps to about $84.95 a month, and the surprise recurring charge plus cancellation friction are the recurring gripes — more visible on Trustpilot and PissedConsumer than on its BBB page, which shows only a handful of complaints.
Does Relief Factor actually work?
The doses are disclosed, which is a plus, but the omega-3 and curcumin are underdosed versus joint research, and resveratrol and icariin have weak human evidence for pain. There’s no published trial on the finished formula, so any benefit is uncertain — see our review.
Is Relief Factor a scam?
There’s no confirmed FTC action, and the product itself is a real, disclosed-dose supplement, so “scam” overstates it. But the trial-to-subscription billing model catches people off guard, which is why most complaints are financial rather than about the product’s safety.
