Scroll for long enough and you’ll find someone promising to help you outsmart ageing, fatigue, or your own biology — usually with a discount code attached. Biohacking has grown from a genuine curiosity about human optimization into a marketing category, and somewhere in that transition, a lot of good questions got buried under a lot of bad advice.

The appeal is real — and so is the problem

There’s nothing wrong with wanting to understand your own body better. The instinct behind biohacking — measure, test, adjust — is the same instinct behind good medicine. The problem is who’s doing the talking. Much of today’s wellness content is produced by people with large followings and no clinical training, promoting protocols that were never tested on anyone but themselves, and often selling the very products they’re recommending.

Red flags worth knowing

A little pattern recognition goes a long way:

• Absolute language. “Miracle,” “hack,” “cure” — biology rarely works in absolutes, and claims that promise it usually should be treated with suspicion.
• No credentials, or the wrong ones. Enthusiasm is not the same as expertise. It’s worth asking who is actually behind the advice, and what qualifies them to give it.
• A product at the center of the story. When every piece of advice leads back to a supplement, device, or subscription, the content is an advertisement wearing the costume of education.
• Fear of “mainstream” medicine. Legitimate practitioners build on established science; they don’t need to discredit an entire field to sell you something.
• One-size-fits-all protocols. Your hormones, history, and biology are not identical to anyone else’s — a protocol that ignores that isn’t personalization, it’s guesswork.

What real personalization actually looks like

Genuine, evidence-informed care starts with data about you: bloodwork, history, and a clear conversation about what you’re actually trying to solve. It evolves as your body does, and it’s delivered by someone who can be held accountable for the outcome — not an algorithm optimizing for engagement.

Curiosity about your own health is worth protecting. The best way to do that isn’t to tune out the wellness conversation entirely — it’s to bring the same critical eye to an influencer’s claims that you would bring to any other unverified source, and to let a qualified professional translate the noise into something that’s actually built for you.
