We help clarify your questions.

  • What is the difference between a subscription and a one-time purchase?

    A subscription purchase is perfect if you want to establish a daily habit that will help you improve your overall health. If you live a busy lifestyle or just don't want to forget to order, a subscription purchase is the right option. We ship your products every 10, 14, or 30 days and you can change your subscription or cancel at any time via your account. By subscribing to Nexus, you also get our subscription discount.

    If you want to try the product before starting a subscription, or give the product as a gift, then the one-time purchase option is for you.

  • Do you lab test your molecules?

    Yes. In addition to the factory lab tests, each batch is third-party tested by Intertek for purity and heavy metals. This is to ensure purity of at least 99% and the absence of heavy metals. Test results are available upon request.

  • When should I take Nexus?

    We recommend taking Nexus in the morning. Studies show that levels of NAD+ follow our circadian rhythm and peak during our waking cycle. Taking Nexus in the morning allows the increase in cellular NAD+ levels from Nexus to coincide with your body's normal peak of NAD+.

  • What dose should I take?

    We recommend starting with two capsules of Nexus every morning, which provides a dose of 333 mg of Nicotinamide. Clinical studies on Nicotinamide have shown that the body's level of NAD+ increases even with a dose as low as 200 mg, and that the increase is proportional to the dose. However, it is important to note that the European Food Safety Authority (EFSA) has established an upper limit for daily intake of Nicotinamide at 900 milligrams for adults.

  • How long will it take to feel the effects of Nexus?

    This is individual and dose-dependent. In our Nexus studies ongoing since 2020, the majority of our test subjects have experienced noticeable effects after just 1-2 months, based on the higher dose. Increased energy and endurance were among the first things our test subjects experienced. These effects can be explained by the increased activity of NAD+, which has a central role in cell metabolism and energy production.
