Our Science

Personalized Medicine Didn’t Start in Silicon Valley. It Started in India.

AYURVEDA WAS THE FIRST. NOW ARVASI POWERS IT WITH CLINICAL EVIDENCE.

For 5,000 years, Ayurveda has known what modern medicine is only now rediscovering: health is not one-size-fits-all. It’s personal, seasonal, and inseparable from the rhythms of nature.

At Arvasi, we’ve taken this timeless system and layered it with modern clinical science. Using your Dosha-Data™—the blueprint of your digestion, hormones, stress, and sleep—we translate ancient wisdom into precise prescriptions you can actually use.

Because you don’t need another trend. You need a system designed for your biology.

The Four Systems That Define Your Health

Balance them, and every part of life gets easier.

Circadian Rhythm

Your body’s internal clock runs every system—yet modern life has thrown it off course. Late nights, blue light, skipped meals: they all scramble your hormones, energy, and immunity. Arvasi prescriptions reset your body clock with seasonal timing, so your biology runs in sync with nature.

Strong circadian rhythms cut risk of heart disease, hypertension, and obesity by up to

62%

Aligned rhythms improve glucose control, lower cortisol, and boost melatonin.¹⁻³

  • Deeper sleep
  • Hormonal harmony

  • Daily energy that lasts

Gut Microbiome

Your gut doesn’t just digest food—it dictates mood, immunity, and even skin health.

Arvasi toolkits repair the gut at its root: oral care, spices that fight inflammation, easy-to-digest meals, and practices that calm the gut-brain axis.

70%

of your immune system lives in your gut.

Studies show supporting the microbiome improves digestion, clears skin, and optimizes energy.⁴

  • Fewer breakouts

  • Smoother digestion

  • Resilient immunity

Nervous System Regulation

Your body cannot heal in survival mode. Chronic stress locks you in fight-or-flight, draining focus, sleep, and mood.
Arvasi practices are designed to flip the switch—to activate your parasympathetic nervous system, ease tension, and restore calm.

Breath and movement practices show up to

28%

improvement in nervous system regulation.

Calming your stress response improves sleep, lowers anxiety, and clears mental fog.⁵⁻⁶

  • Less anxiety
  • Better sleep
  • More clarity

Hormonal Health

Hormones shape everything—mood, weight, cycles, sleep, skin. But stress, poor sleep, and inflammation throw them out of balance.

Arvasi toolkits use circadian rhythm, food as medicine, and supplements to bring your hormones back into flow.

80%

of women report hormonal imbalance by midlife.

Research shows supporting hormonal health improves mood, metabolism, and sleep.⁷

  • Fewer mood swings
  • Smoother transitions through peri/menopause
  • Improved sleep

When These Systems Are Balanced, So Are You.
