FAQ

New Jersey wellness FAQs

Can I take a wellness genetic test in New Jersey?

No clinic visit is needed. At-home wellness genetic tests ship to New Jersey: you collect a sample at home, mail it back and review results online — ideally with a clinician in New Jersey who can put them in context. See our genetic testing guide.

What's the best time of year to exercise outdoors in New Jersey?

Spring and fall offer the most comfortable conditions. In summer, train early in the morning or after sunset and check the heat index; in winter, mild afternoons are ideal for longer outdoor sessions.

Can you get enough vitamin D from the sun in New Jersey?

New Jersey sits at about 40.1°N. At this latitude, winter sunlight is too weak for meaningful vitamin D production for roughly four months. That's roughly November through February. Skin tone, sunscreen, age and time outdoors also matter, so a blood test is the only way to know your level — ask your clinician before supplementing.
