Final week I shared my private longevity should‑haves. The response was overwhelming—a lot of you shared tales of residing with continual sickness, caring for fogeys with dementia, or just wanting to remain wholesome on your youngsters and grandkids. Others despatched sharp questions in regards to the science behind longevity.
Studying via all of it, I noticed the identical themes come up time and again. That’s what I need to reply right now.
1. What’s the behavior that makes the largest distinction?
My reply: sleep. Should you’re not sleeping properly (emphasis on the phrase “properly”) nothing else strikes the needle. Because of this I known as my e-book “The 8-Hour Sleep Paradox” — folks get their eight hours and assume they’re carried out, when that couldn’t be farther from the reality.
Why is a dentist speaking about sleep? As a result of the way you sleep relies on how your mouth and jaw developed as a toddler.
Dentists are literally educated on this. The American Academy of Dental Sleep Drugs (AADSM) exists to assist dentists acknowledge and deal with sleep-disordered respiration, as a result of the form of your jaws, how your tooth match collectively, and the place your tongue rests can all have an effect on whether or not your airway stays open at night time.
This isn’t fringe—it’s accepted, evidence-based care. Which is why I say usually…
In case your dentist doesn’t ask you about your sleep, it’s time to discover a new dentist.
After sleep, spermidine (hyperlink to the one I take) and C15:0 dietary supplements are the 2 I by no means drop, particularly for longevity. They handle mobile getting old instantly—autophagy and membrane power.

2. Why We Wrestle to Stick With Habits (and Repair It)
Most individuals don’t battle with realizing what to do. They battle with doing it, constantly. That’s the place the true longevity work occurs.
One reader instructed me: “The issue is execution. I do know a lot of these items, however I can’t follow them.”
I’ve seen this in sufferers and in my very own life. One story I’ve instructed for many years: if flossing feels overwhelming, begin with simply one tooth. That impossibly low bar is tough to fail at, and over time the behavior grows—two tooth, then three, till the entire mouth will get carried out.
The identical psychology applies to any longevity behavior.
The answer is to not pile on extra. It’s to decide on fewer levers and cut back friction:
- Choose one non-negotiable and make it ridiculously simple and small (i.e. floss one tooth).
- Stack a brand new behavior onto an current one (stroll proper after dinner, tape your mouth proper earlier than mattress).
- Observe your wins—consistency compounds.
3. Your Complement Questions, Answered: Magnesium, Spermidine, C15:0, Omega-3s
I acquired dozens of questions on dietary supplements. Among the most typical:
- Is it protected to take magnesium in case your ranges are regular?
Sure. Blood checks don’t inform the complete story. And most of us are nonetheless decrease than is perfect, even when serum ranges look “regular.” Magnesium helps over 300 enzymatic reactions, calms the nervous system, regulates blood stress, and improves sleep depth. Latest 2024 critiques hyperlink larger magnesium consumption with decrease all-cause mortality and decreased threat of dementia and heart problems. I take this one every day as a result of it’s one of the best in the marketplace. - Is spermidine gluten-free?
It relies on sourcing. I take advantage of a gluten-free one. You received’t get sufficient from meals alone—most research counsel supplementation in order for you dependable autophagy advantages. - Is C15:0 simply one other fish oil?
No. C15:0 is a hint fatty acid that strengthens getting old cell membranes. It enhances omega-3s however works in a different way—consider it as restoring cell structure, not simply lowering irritation. (Hyperlink to the one I take) - Do longevity dietary supplements mess with hormones?
There’s no proof that spermidine or C15:0 disrupt hormones. Most concern on-line is with compounds like resveratrol or rapamycin, which act on pathways that may overlap with hormone regulation. Spermidine and C15:0 have clear security profiles in present analysis. - Do I want each omega‑3s and C15:0?
Sure—they aim completely different pathways. Omega‑3s cut back irritation and assist mind/coronary heart. C15:0 stabilizes cell membranes and prompts AMPK/PPAR for metabolic resilience. - What’s one of the best time of day to take spermidine?
Analysis is early, however as a result of spermidine helps autophagy, many take it within the morning or throughout a fasting window. Consistency is extra vital than timing. - Can I mix C15:0 with omega‑3s?
Sure. Research counsel they’re complementary: omega-3s cut back irritation, whereas C15:0 strengthens membranes and improves metabolic signaling. - Does spermidine work immediately?
No. Autophagy is an extended‑time period course of. Advantages accumulate over months. Human trials present measurable enhancements in resilience markers after constant use. - What’s distinctive about C15:0 in comparison with different fatty acids?
It’s a hint odd‑chain saturated fatty acid. Not like most saturated fat, it’s linked to decrease irritation, improved cell restore, and better metabolic stability. - Can omega‑3s change spermidine?
No. Omega‑3s and spermidine work on completely different longevity pathways. One helps irritation management, the opposite clears broken proteins and organelles.
4. Oral Well being = Longevity Drugs
What in case your dentist holds the key to residing longer?
Right here’s my view:
- Oral well being is systemic well being. We now know that micro organism from the mouth—particularly P. gingivalis, a keystone pathogen in gum illness—don’t keep confined to the gums. They will enter the bloodstream, set off irritation in distant organs, and have been detected within the brains of sufferers with Alzheimer’s illness. Research counsel their toxins (gingipains) might harm neurons and speed up cognitive decline. This is without doubt one of the clearest examples of the mouth–physique connection: the well being of your gums and oral microbiome has direct penalties on your mind, coronary heart, and general longevity.
- Flossing is without doubt one of the strongest preventive instruments we’ve got. It disorganizes the pathogens that begin the cascade and retains gum illness from gaining a foothold. As soon as illness is superior, you’ll want skilled care too—however every day flossing is the behavior that ideas the percentages in your favor.
- Oil pulling: swishing oil (like coconut or MCT) for two–5 minutes. It helps the oral microbiome, and is protected. Consider it as an addition to, not a alternative for, brushing and flossing.
- Hydroxyapatite: I might solely use Fluidnova model nano‑hydroxyapatite, which is biomimetic and properly‑studied for remineralization and systemic security. It integrates naturally with enamel, helps oral well being with out fluoride, and has a robust security profile. (Hyperlink to my toothpaste)
I’ll depart you with this:
The largest threat to your longevity is feeling overwhelmed. Select one or two levers, get them rock-solid, and solely then, you may layer on extra.
