Longevity Medicine, Functional Wellness & Anti-Aging Insights from HormoneSynergy®

A 90-day human pilot study of Big Bold Health HTB Rejuvenate found intriguing changes in epigenetic aging, immune-cell patterns, and biological pathways associated with immune aging. The often-quoted 47% result is real, but it came from a small subgroup. Here is what the study actually found and why the larger story may be more interesting.

MegaIgG2000 is a dairy-free, serum-derived bovine immunoglobulin supplement available as a powder or capsules. Both provide 2 grams of ImmunoLin® per serving, but the powder contains slightly more IgG and allows more flexible dosing, while the capsules offer greater convenience. 

The global wellness economy has reached $6.8 trillion, almost four times the size of the pharmaceutical industry. That growth reflects a welcome interest in prevention, longevity, nutrition, fitness, and healthier aging. It has also created a marketplace where supplements, testing, coaching, biohacking, and medical-looking programs can be difficult to distinguish from actual medical care.

Low triglycerides, good insulin sensitivity, normal blood pressure, and excellent fitness are all favorable for cardiovascular health. But do they make a very high LDL-C or ApoB less important? The biology is more nuanced than either side of the cholesterol debate usually admits.

A large UK Biobank study linked long-term statin use with faster declines in grip strength and appendicular lean mass. The signal deserves attention, but the widely repeated “73% muscle loss” interpretation is wrong, and newer studies have not confirmed that statins increase sarcopenia risk.

A large 2026 prospective study found that sarcopenic obesity, the combination of excess body fat with low muscle mass and function, was associated with a 34% higher risk of dementia. The strongest and most consistent signal was not body weight. It was declining muscle strength. The findings reinforce an important longevity principle: preserving muscle while improving body composition may matter far more than simply making the number on the scale smaller.

A rising coronary artery calcium score usually sounds like worsening heart disease. After statin therapy, the interpretation becomes more complicated. Statins can reduce cardiovascular events, slow growth of noncalcified plaque, and shift existing coronary plaque toward a denser, more calcified phenotype. Because the standard Agatston calcium score gives greater weight to dense calcium, the CAC number can rise even while plaque is becoming more stable. This is why current cardiovascular guidelines do not recommend repeating CAC scans to judge whether statin therapy is working.

A coronary calcium score of zero is genuinely reassuring, even when lipoprotein(a) is elevated. Long-term cohort data show that people with high Lp(a) and CAC = 0 generally have much lower near-term cardiovascular risk than people who already have significant coronary calcium. But CAC only detects calcified plaque, while newer CCTA research links elevated Lp(a) with noncalcified and higher-risk plaque. The practical answer is not to ignore the zero or ignore the Lp(a). They are telling you different things about cardiovascular risk.

We usually talk about exercise, cardiovascular risk, muscle, sleep and metabolic health as things we do for ourselves. After years of marriage, I see that differently. The health we carry into later life will affect the person beside us—their freedom, their plans, the experiences they hoped we would share and, sometimes, whether they become our caregiver. Longevity medicine gives us an opportunity to start thinking about that much earlier.

C15:0 is being promoted as a foundational longevity nutrient that strengthens cells and slows biological aging. The biology is interesting, and early human studies deserve attention. But C15:0 has nowhere near the clinical evidence behind Mediterranean nutrition, extra-virgin olive oil, omega-3 fatty acids in appropriate patients, resistance training or creatine. Here is where we think it belongs today.

GLP-1 medications can produce substantial weight loss and meaningful improvements in metabolic health. But the number on the scale does not tell us whether someone is losing fat, muscle, or both. In longevity medicine, preserving muscle and strength during weight loss deserves just as much attention as the pounds coming off.

PTSD and chronic hypervigilance do not remain neatly confined to mental health. Sleep, cardiovascular risk, metabolic health, hormones, inflammation and even markers of biological aging may intersect with years of living in a persistent threat-response state.
