Hormone Balance
Track the hormones that govern energy, mood, libido, and body composition — and see how they shift month over month.
Why hormone balance matters
Hormones are chemical messengers that regulate nearly every system in your body — from how much energy you wake up with, to how you build muscle, to how you respond to stress. When key hormones drift out of range, the effects are often subtle at first: persistent fatigue, low motivation, poor recovery, brain fog, or changes in mood and libido.
Because hormones interact in tightly balanced ratios, a single snapshot can be misleading. Testosterone, estradiol, and SHBG, for example, all influence how much biologically active hormone is actually available to your tissues. Tracking these markers together — and over time — is what reveals the real picture of your hormonal health.
- Total and free testosterone directly affect muscle mass, drive, mood, and metabolic health — in both men and women.
- Estradiol and progesterone shape menstrual regularity, bone density, sleep quality, and emotional balance.
- SHBG determines how much hormone is actually free and active versus bound and unavailable.
- Cortisol, your primary stress hormone, influences sleep, blood sugar, inflammation, and recovery when chronically elevated.
What we measure
Reference ranges are general guidelines. VitalDrop emphasizes your personal trend over time rather than a single in-or-out snapshot.
Total Testosterone
The total amount of testosterone circulating in the blood, including both bound and free forms.
Free Testosterone
The biologically active fraction not bound to proteins — the portion your tissues can actually use.
Bioavailable Testosterone
Free testosterone plus albumin-bound testosterone — the fraction readily available to your tissues.
Estradiol (E2)
The primary estrogen, critical for bone health, libido, cardiovascular protection, and menstrual function.
Progesterone (female only)
Balances estrogen, supports sleep and mood, and regulates the menstrual cycle and fertility.
SHBG (Sex Hormone-Binding Globulin)
A protein that binds sex hormones. High SHBG reduces free testosterone availability.
Cortisol
The body's primary stress hormone. Chronically elevated cortisol disrupts sleep, metabolism, and immune function.
What affects these markers
- Sleep duration and quality
- Chronic physical or psychological stress
- Body composition and visceral fat
- Training volume and overtraining
- Nutrient intake (zinc, magnesium, vitamin D)
- Age-related decline
How VitalDrop helps
- Monthly capillary testing captures hormone fluctuations your annual physical misses.
- Trend graphs reveal whether a value is stable, rising, or falling — not just in-range or out.
- Personalized AI insights connect hormone shifts to lifestyle factors you logged.
- Physician-reviewed results flag clinically meaningful changes before they become problems.

Frequently asked questions
Hormones fluctuate on daily and monthly cycles, so a single test rarely tells the full story. Most members benefit from monthly testing for the first three months to establish a true baseline, then continuing monthly based on whether they are actively optimizing (e.g., adjusting training, diet, or therapy) or maintaining.
