Final week I shared my private longevity should‑haves. The response was overwhelming—lots of you shared tales of dwelling with continual sickness, caring for fogeys with dementia, or just wanting to remain wholesome in your youngsters and grandkids. Others despatched sharp questions concerning 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 this moment.
1. What’s the behavior that makes the most important distinction?
My reply: sleep. For those who’re not sleeping effectively (emphasis on the phrase “effectively”) nothing else strikes the needle. This is the reason I known as my e book “The 8-Hour Sleep Paradox” — folks get their eight hours and suppose they’re performed, when that couldn’t be farther from the reality.
Why is a dentist speaking about sleep? As a result of the way you sleep is dependent upon 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 respiratory, 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 typically…
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 deal with mobile getting older instantly—autophagy and membrane energy.

2. Why We Wrestle to Stick With Habits (and Easy methods to Repair It)
Most individuals don’t wrestle with figuring out what to do. They wrestle with doing it, constantly. That’s the place the actual longevity work occurs.
One reader advised me: “The issue is execution. I do know lots of these items, however I can’t persist with them.”
I’ve seen this in sufferers and in my very own life. One story I’ve advised 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 performed.
The identical psychology applies to any longevity behavior.
The answer is to not pile on extra. It’s to decide on fewer levers and scale back friction:
- Choose one non-negotiable and make it ridiculously straightforward 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).
- Monitor your wins—consistency compounds.
3. Your Complement Questions, Answered: Magnesium, Spermidine, C15:0, Omega-3s
I bought dozens of questions on dietary supplements. A number of the most typical:
- Is it secure 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. Current 2024 critiques hyperlink increased magnesium consumption with decrease all-cause mortality and lowered threat of dementia and heart problems. I take this one day by day as a result of it’s the very best in the marketplace. - Is spermidine gluten-free?
It is dependent upon sourcing. I take advantage of a gluten-free one. You received’t get sufficient from meals alone—most research counsel supplementation if you need dependable autophagy advantages. - Is C15:0 simply one other fish oil?
No. C15:0 is a hint fatty acid that strengthens getting older cell membranes. It enhances omega-3s however works in another 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 would like each omega‑3s and C15:0?
Sure—they aim totally different pathways. Omega‑3s scale back irritation and assist mind/coronary heart. C15:0 stabilizes cell membranes and prompts AMPK/PPAR for metabolic resilience. - What’s the very 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 scale back irritation, whereas C15:0 strengthens membranes and improves metabolic signaling. - Does spermidine work immediately?
No. Autophagy is a protracted‑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. In contrast to most saturated fat, it’s linked to decrease irritation, improved cell restore, and higher metabolic stability. - Can omega‑3s change spermidine?
No. Omega‑3s and spermidine work on totally 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 dwelling 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’ll 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) could 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 in your mind, coronary heart, and total longevity.
- Flossing is without doubt one of the strongest preventive instruments we now have. 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 day by day flossing is the behavior that suggestions the chances in your favor.
- Oil pulling: swishing oil (like coconut or MCT) for two–5 minutes. It helps the oral microbiome, and is secure. Consider it as an addition to, not a substitute for, brushing and flossing.
- Hydroxyapatite: I might solely use Fluidnova model nano‑hydroxyapatite, which is biomimetic and effectively‑studied for remineralization and systemic security. It integrates naturally with enamel, helps oral well being with out fluoride, and has a powerful security profile. (Hyperlink to my toothpaste)
I’ll depart you with this:
The most important threat to your longevity is feeling overwhelmed. Select one or two levers, get them rock-solid, and solely then, you’ll be able to layer on extra.
