As a functional practitioner, I’ve been watching something with growing concern. More and more people are turning to AI for wellness advice, and sometimes for medical advice too. It’s easy to see why. It’s free, it’s available any time of the day or night, and it answers right away, without a waiting list or a copay. When you’ve been dealing with unpleasant symptoms and can’t get answers, that kind of access can feel like a lifeline.

I use AI myself (in fact, it’s helping me write this article), and I find it extremely useful. It’s a helpful way to gather health information, look up a mechanism, or get a quick overview of a topic. But I never rely on it completely, especially when the topic is outside my expertise. That’s when I’m least able to tell whether what I’m reading is accurate, incomplete, or simply what I hoped to hear. And if that’s true for someone who works in this field every day, it makes sense to approach it thoughtfully when it comes to your own health.

 

How AI Comes Up With Its Answers

AI chat tools learn by studying enormous amounts of written text, much of it from the internet. When you ask a question, the tool predicts a helpful-sounding response based on patterns in everything it has read.

That’s why AI is so good at explaining things clearly. It’s also why it can repeat the same information you already see online, and why its answer depends so much on how you ask the question. It isn’t examining you. It’s responding to your words.

 

Where AI Can Be Helpful

Used thoughtfully, AI can support your health in some practical ways.

• Explaining how the body works. AI does a nice job with plain-language explanations of things like blood sugar balance, the gut-brain connection, or how stress affects hormones.
• Translating medical language. If a term on your lab report or in your doctor’s notes is confusing, AI can help you understand what it means.
• Describing what a functional test looks at. It can explain what a stool test, cortisol panel, or full thyroid panel measures and why a practitioner might order one.
• Preparing for appointments. AI can help you organize a symptom timeline, research a topic, and write down questions, so your time with your doctor or practitioner is more productive.
• Making a plan easier to live with. Once you have a personalized plan, AI is great for recipes, grocery lists, meal ideas, and ingredient swaps that fit the foods you’re avoiding.

 

Where AI Falls Short

This is important information, because these limits aren’t always obvious.

 

It Only Knows What You Tell It

AI has no history with you. It hasn’t seen your labs over time, it doesn’t know about the medication you forgot to mention, and it doesn’t know you’ve been sleeping five hours a night since your mom got sick. It builds its answer from whatever you typed, and nothing more.

Your Question Shapes the Answer

If you ask, “What supplements help with adrenal fatigue?” you’ll most likely get a list of supplements. AI usually answers the question as asked. It rarely steps back to wonder whether that’s the right question for what you’re experiencing. If you already have a theory about what’s wrong, AI tends to build on it rather than test it.

It Tends to Tell You What You Want to Hear

AI tools lean toward being agreeable and encouraging. That feels good, and it isn’t always what you need. A good practitioner is kind, and will also gently tell you what you may not want to hear, like “I don’t think the supplements are the issue. I think your body needs more rest.”

It Can Sound Sure When It’s Wrong

AI can share incorrect information, or even reference studies that don’t exist, in the same calm and polished tone it uses for accurate information. Without a trained eye, there’s no easy way to tell the difference.

It Can’t Read the Whole You

A practitioner notices the pause before you answer, the offhand comment about skipping lunch, or the way your energy shifts when you talk about work. Those small moments often hold the most important clues. AI only has the words in the box.

 

What About Uploading Your Lab Results?

Some people are now uploading test results and asking AI to interpret and create a protocol. AI will often do it, and the result can look impressively personalized. It’s built from your numbers, after all.

Here’s what that plan may be missing:

• Your full context. Symptoms, medications, health history, life stage, and what you’ve already tried all change how results should be read.
• Sequencing and pacing. In functional care, the order of steps matters. Moving too fast with antimicrobial herbs, for example, can leave you feeling worse and unsure whether to keep going.
• Supplement safety. Some herbs and supplements interact with medications and should be avoided. Also, AI doesn’t know which brands are vetted and trustworthy, or proper dosage for an individual with a particular goal.
• Clinical judgment about the test itself. Some functional tests are interpreted differently by different practitioners, and certain results carry more weight than others depending on the bigger picture. AI tends to take every flag at face value, which can lead to unnecessary restriction.
• Someone to adjust along the way. A protocol isn’t a one-time document. It changes based on how you feel at week two, what retesting shows, and what you can realistically keep up with.

A food sensitivity test is a good example. Results can come back with a long list of “reactive” foods. Remove them all without guidance, and you can end up eating a very narrow diet with no clear plan for moving forward. That can add long-term stress around food that your body doesn’t need.

 

What About Services Like Function Health?

A newer option sits somewhere between asking a chatbot and working with a practitioner. Function Health is a membership service that runs a large set of lab tests and then interprets them for you. With the subscription, members get blood work twice a year covering what the company describes as more than 160 lab tests. Results come back on an online dashboard with written clinician notes, suggested next steps, and access to an AI health coach.

For a lot of people, that’s appealing, and there’s real value in it.

 

What It Does Well

• A lot of data for the price. Many of these markers aren’t part of a standard physical, and ordering them one by one would cost far more.
• Tracking over time. Seeing how your markers change from one round to the next can be more meaningful than a single snapshot.
• A starting point. For someone who has been told “everything looks normal” while still not feeling well, having more information can expand the conversation.

Where It Falls Short

• Recommendations are driven by your numbers. Suggestions are triggered by which markers are out of range. They don’t account for your symptoms, your stress, your sleep, or what’s happening in your life.
• No ongoing conversation. There’s no live, back-and-forth appointment where someone asks follow-up questions, notices patterns, or helps you decide what matters most right now.
• More flags can mean more worry. Function Health uses tighter “optimal” ranges than standard labs. That can catch early shifts, but it can also flag results your doctor would consider normal. Without someone to put them in context, a dashboard full of flags can feel overwhelming.
• Blood tests are only part of the picture. For people with digestive issues, a stool test is often one of the most useful tools, and it isn’t currently part of the Function Health offering. Neither is a conversation about how you eat, when you eat, and how you feel afterward.
• You’re on your own to put it into practice. A list of recommendations is different from a personalized plan, a first small step, and someone to check in with as you go.

Using Both

This doesn’t have to be either-or. If you already have results from a service like Function Health, they can be a valuable place to begin. A functional practitioner can review them alongside your symptoms and history, decide whether any additional testing would help, and turn the numbers into a plan that fits your body and your life.

 

What a Practitioner Brings That AI and Apps Can’t

Working with a practitioner is a relationship, not a transaction. Here’s what that partnership offers:

• Knowing which questions to ask, and following the thread when something doesn’t add up
• Reading your results alongside your symptoms, history, and goals
• Helping you find your most important first small step instead of handing you twenty at once
• Checking in, adjusting the plan, and noticing progress you might not see yourself
• Being honest with you, with compassion

 

How to Use AI Wisely

You don’t have to avoid AI altogether. It makes sense to use it as a learning tool rather than a decision-maker.

• Use it to understand, not to diagnose
• Give it full context, and ask, “What might I be missing?” or “What would argue against this?”
• Treat any supplement, dosage, or elimination diet suggestion as a question to bring to your practitioner
• If an answer leaves you more anxious than before, take that as a sign to talk with a person
• Bring what you’ve learned to your appointment as a starting point for conversation

 

In Summary

AI can read the numbers and words you put in. A practitioner understands the person.

There’s a place for both on your health journey. AI can help educate and make a plan easier to follow day to day. But deciding what that plan should be, especially when autoimmunity, digestive issues, or the changes of perimenopause are part of the picture, calls for someone who knows you.

If you’ve been piecing things together on your own and you’re ready for a clearer path, I’d love to hear your story. A Complimentary Discovery Call is a no-pressure way to talk through what’s going on and see whether working together feels like the right fit.
