Superior absorption. Sublingual delivery achieves up to 95% bioavailability vs. 10–20% for oral capsules.
✓
Precisely dosed. 100mg NAD+ per strip — standardized and consistent, no measuring required.

FAQ

Your questions, answered.

How do I use the NAD+ strip?

Place one strip under your tongue and allow it to dissolve completely — typically 30 to 60 seconds. For best results, use once daily in the morning on an empty stomach. Avoid eating or drinking for 5 minutes after placing the strip.

Why sublingual instead of capsules or injections?

Oral capsules pass through the digestive system where most active compounds break down — resulting in only 10–20% absorption. Injections achieve higher absorption but require needles and a complex routine. Sublingual delivery absorbs directly through the oral mucosa, achieving up to 95% bioavailability with zero needles.

When will I start feeling results?

Most users report noticeable improvements in energy and mental clarity within 1 to 2 weeks of daily use. Cellular-level benefits — improved recovery and skin quality — typically become evident within 4 to 6 weeks of consistent use.

Can I cancel my subscription anytime?

Yes — cancel, pause, or modify your subscription at any time from your account dashboard. No cancellation fees and no long-term commitments required.

Subscription vs. one-time — what's the difference?

A monthly subscription is $179.10 per month — a 10% savings over the $199.00 one-time purchase price. Subscribers receive priority shipping and first access to new products.

Is NAD+ safe? Any side effects?

NAD+ is a naturally occurring coenzyme found in every cell in your body. It is generally well-tolerated. Some users report mild flushing or a slight tingling sensation when first starting, which typically resolves within a few days. Consult your physician if you have a pre-existing medical condition.
