Frequently Asked Questions

BIGVITA Youth+ is ideal for individuals seeking to address anti-aging concerns, enhance overall well-being, combat fatigue, boost energy levels, promote healthier skin and hair, and optimize cognitive function.

Many people begin to feel improvements in sleep quality and mental clarity within the first week. Increased physical energy and metabolism are often noticeable in 1–2 weeks. Skin tone and hydration typically improve over 2–4 weeks, while reduced hair shedding and sharper memory or faster thinking may take 4–8 weeks. For the best and most consistent results, we recommend continuing Youth+ for at least 8 weeks.

Yes. Youth+ contains NAD+, ergothioneine, and spermidine — naturally occurring compounds in the human body that play key roles in cellular health and protection against oxidative stress. Current research supports their safety for long-term supplementation to help maintain optimal levels as we age.

It’s normal to feel a little more tired at first — it’s a sign your body is adjusting. Youth+ works in stages, and early on, spermidine supports deep cellular renewal and repair, which can temporarily use extra energy. This phase is usually short, and many people start feeling a noticeable boost in energy and clarity within 1–2 weeks. Everyone’s body is different, so your experience may vary. If fatigue lingers or you have health concerns, it’s always a good idea to check with your healthcare professional.
