Most supplement routines are guesswork and wasted money. Here is how to build a stack your bloodwork actually justifies.
For years my supplement routine was a guess. Then I got a full blood panel and rebuilt the entire stack around what my body was actually telling me. Low DHEA. Thyroid antibodies creeping up. Liver enzymes just over range. A vitamin D number I wanted higher. Low red-blood-cell magnesium.
Every single addition had a reason behind it, tied to a number. That is the whole philosophy. Do not build a stack off a YouTube video or a podcast. Build the short list your bloodwork justifies, then actually take it every day.
These four have strong evidence and a wide enough benefit that most people doing this will end up using them. Still confirm against your own panel.
Around 5g daily. One of the most studied supplements there is. Supports strength and lean mass, especially in a deficit, with cognitive upside too. The classic hair-loss worry is not supported by the evidence.
Roughly 2g of combined EPA and DHA daily. Helps resolve inflammation at the source, supports heart and brain health. Low omega-3 status is genuinely common. An OmegaCheck test can dial in your dose.
Vitamin D acts more like a hormone than a vitamin. K2 directs calcium toward bone and away from arteries. Most people test low. Dose to your bloodwork and retest.
Involved in hundreds of processes including sleep and blood pressure. The glycinate form is calming and gentle on the gut, which makes it ideal at night. Up to half of adults run low. Pairing it with a small dose of boron supports bone density and Vitamin D utilization at the same time.
These are not for everyone. They earn a place only when a specific marker on your panel points to them.
NAC feeds glutathione, your master antioxidant, and supports the lungs and brain. There is also a useful side benefit for sleep: NAC has been shown to improve slow-wave sleep and reduce apnea-related arousals, which matters for the meaningful share of men over 35 who quietly have undiagnosed sleep apnea. TUDCA supports bile flow and the liver. Worth considering if liver enzymes like ALT drift above range.
If thyroid antibodies are elevated, the specific cofactors that matter are selenium, zinc, and iodine. Black cumin seed oil has data on lowering thyroid antibodies. This is more precise than a generic "thyroid support" label, look for those actual ingredients.
Supports energy and helps lower homocysteine, a cardiovascular risk marker. Worth a look if homocysteine is elevated, or if you are on TRT, which can burn through B vitamins.
Supports mitochondrial energy and heart health. Worth strong consideration for anyone with a known cardiovascular risk factor, and commonly depleted by statin use.
Upstream hormones that support mood, recovery, and sleep. Only worth supplementing if your panel shows you are genuinely low, and best done with a clinician aware of the rest of your hormone picture.
Studied for supporting insulin sensitivity and blood glucose control. A reasonable consideration if fasting glucose, insulin, or A1c are creeping up, alongside the obvious diet and training fixes.
Protein is the lever most people miss, especially busy people and anyone on a GLP-1 with a suppressed appetite. Whole-food protein first, always. But a quality shake makes the daily target realistic on a hard day. My go-to is Fairlife Core Power: around 26 to 42 grams of protein, no blender, no mess, available at any grocery store. Convenience is what makes a habit stick.
Sleep is a foundation, not an afterthought. A simple evening stack: magnesium glycinate, glycine, L-theanine, and taurine, with pregnenolone if your panel supports it. Chamomile or valerian tea and a small amount of CBD or CBN can help too. The bigger win for most people is behavioral, though: stop scrolling and cut screens before bed so your mind has room to unwind.
Supplements are not a substitute for a foundation of training, diet, and sleep, and they are not regulated like medications. Build the short list your bloodwork justifies, take it consistently, and retest. When in doubt, talk to a clinician or a registered dietitian.
Bring your bloodwork to a consultation and we will build the short list that fits you.
