Hey everyone, it's me here with another installment in the 200-Year Life Project. We're all about stacking the odds in favor of not just living longer, but thriving with energy, sharp minds, and strong bodies deep into our centuries. Today, I'm shining a light on Vitamin D3 – often called the “sunshine vitamin” because our skin makes it from UVB rays. But as we age, production drops, and deficiency becomes rampant. I've been diving into the latest research (up to late 2025), and the evidence is compelling: optimizing Vitamin D3 levels could be a cornerstone for healthier aging and potentially extending our healthspan.
Why Vitamin D3 Matters More as We Age
Vitamin D3 (cholecalciferol) is the form our body produces naturally and the one most supplements use – it's more effective at raising blood levels than D2. It acts like a hormone, regulating over 1,000 genes involved in immunity, inflammation, cell growth, and more.
Deficiency is shockingly common, especially in older adults: skin synthesis drops by about 50% by age 70, plus less time outdoors, thinner skin, and reduced kidney/liver efficiency in converting it to active forms. Levels below 20-30 ng/mL (50-75 nmol/L) are linked to accelerated aging hallmarks like inflammation, mitochondrial dysfunction, and telomere shortening.

Resveratrol is a natural polyphenol, basically a type of antioxidant produced by plants to protect themselves from stress like UV rays or infections. We humans get it mostly from foods like red grapes (and yes, red wine), berries, peanuts, and even dark chocolate. It's been studied since the 1990s, but it really hit the spotlight when researchers linked it to the “French Paradox” – how the French eat rich foods but have lower heart disease rates, possibly thanks to their wine habits. In supplement form, it's often extracted from Japanese knotweed, and doses can range from 100mg to way higher in clinical trials. 
First, let's get real about the numbers. Living to 200 isn't just about beating aging – it's about funding a marathon existence. At my age, I'm already retired, but extending that to 2155 (yep, that's when I'd hit 200) means covering inflation, medical breakthroughs, housing, food, and maybe even some fun like attending BitBlockBoom conferences well into the 22nd century. 
Magnesium is involved in over 300 enzymatic reactions, but many forms have poor absorption or GI upset. Glycinate shines: High bioavailability, gentle on the stomach, and the glycine component adds its own sleep-promoting benefits (like my separate glycine dose).
Studies link it to:
Glycine is a non-essential amino acid—your body makes some, but we often don't get enough from diet alone (rich in collagen/bone broth). It's inhibitory in the brain, acting like GABA to promote calm, and uniquely lowers core body temperature—a key sleep trigger.
L-Theanine is a non-protein amino acid found almost exclusively in tea leaves (especially green tea). It crosses the blood-brain barrier and influences neurotransmitters: boosting GABA, serotonin, and dopamine for calm, while increasing alpha brain waves—the relaxed, alert state like meditation. 
Your circadian rhythm—the 24-hour internal clock governing sleep, hormones, metabolism, and repair—is primarily set by light exposure. Morning sunlight, especially the mix of red/orange wavelengths at dawn and the blue light spike as the sun rises, signals your suprachiasmatic nucleus (SCN) in the brain that it's daytime. 
What Makes Chlorella a Superfood?
It has taken quite a while to loose this much weight. I did not gain it over night, and I did not loose it over night. People who have not seen me in a while really notice. I hear things like OMG, You have lost some weight!, and “Have you been on a diet?”
I attended my first concert when I was in the 9th grade so I guess that was around 1969. We went to see a concert by a singer named Alice Cooper.
Yes, I was hanging out with Tom Cruise.
I moved to Texas from South Carolina in 1979. Arriving in Texas with less than $10 in my pocket and immediately started a new job as a door to door salesman selling storm windows and doors.
