True Story: Ralph had no symptoms and no idea he was at higher risk for a heart attack. Tests revealed an elevated Lp(a) and a calcium score over 600. A silent threat Ralph only discovered through Function. That data sparked his transformation. Today, Ralph is a certified health coach on a mission to help others catch what he almost missed.

As someone who is very particular about product quality, I give @function an A+. Their customer experience is outstanding. 1) Scheduling a blood draw takes about 30 seconds 2) Results come back fast 3) The depth of insight you get into your health is on another level

@mousemastery @pli_cachete Happy to help you gain more insight into your health, Leah. 🧡

@eleven21 Hey John. You can cancel your Function annual membership or opt out of renewal at anytime. No phone call necessary. To make changes, log in to Function, go to your profile, and select Your Membership.

@nateliason @WHOOP Function Health makes you call them to cancel - which is illegal in CA. Why doesn't Quest just build out a team to do testing themselves?

Very disappointed by this from @WHOOP I bought a bundle of four lab tests last year… and apparently my purchase expires? There’s zero reason to take away tests I already paid for.

@buildandhold @nateliason @WHOOP Hey Tyson, please send us a DM so we can look into this further for you.

@nateliason @WHOOP @function did this to me, as well. Very disappointing!

@FX2185 @drmarkhyman Hi there, we're sorry to hear about your experience. That's not the experience we want for our members. Please send us a DM so we can look into this further.

@drmarkhyman I have just had the worst customer service experience with @function health! I’ve been a member since very early on, but I’m shocked at the ineptitude of the customer service. I wanted you to know because they aren’t representing you well! I will be moving to a competitor.

Do you ever feel like you're high-functioning but quietly running on empty?

@bronzeageshawty Blame the biomarkers. We won't stop you.

Sorry for the uptick in provocation recently. My excellent metabolic health has gotten the better of me.

Low Zinc isn’t always obvious. It can show up as: - Increased susceptibility to infections - Slower wound healing - Impaired smell or taste Knowing your levels can help you understand what your body might be telling you.

Your immune system isn’t just strong or weak. It’s a complex, regulated network. Zinc helps support how immune cells develop and communicate. When levels are low, those processes may be less efficient.

Your body contains ~30 trillion cells. Zinc supports processes throughout the body and plays a key role in immune function.

Check your health. Here’s what to test: Total IgE—a general marker associated with allergic responses Food allergy IgE testing—provides insight into immune response to certain foods Indoor & outdoor allergen IgE testing—provides insight into immune response to common environmental triggers

How? Meet IgE. Immunoglobulin EIgE (IgE) binds to immune cells when your immune system identifies a threat. This can trigger a reaction contributing to symptoms like sneezing, itching, and congestion.

Why does pollen wreck some people—but not others?

Some of my latest labs with @function Note these lab tests are before commencing lipid lowering therapy (my baseline). Point being my goal is to get ApoB down from 75 mg/dl (where I sit with diet/lifestyle alone) to under 50 mg/dl. Why?

Not all supplements work the same. Vitamin D3 has been shown to raise and maintain levels more effectively than D2.

Most people think they understand Vitamin D. But a few details change everything. 🧵⤵️
