NAD+: A key molecule for
cellular function and aging.

The older we get, the more vulnerable our bodies become. But what few know is that one of the main causes behind this, is the gradual decline of NAD+ levels in our cells. NAD+ is a vital molecule that plays several critical roles in our body's functioning. As NAD+ levels decrease, our cells weaken, leaving us more susceptible to age-related diseases and poor health. Specifically, reduced NAD+ levels can impact cellular energy metabolism, DNA repair mechanisms, inflammatory responses, and even the powerhouse of our cells – the mitochondria. This decline in NAD+ is a natural and inevitable process of life. However, emerging research suggests that slowing down this process, and perhaps even reversing it, may be within our reach.

Refueling your body.

The science is complex, but the theory is simple – By increasing NAD+ levels within our cells, we have the potential to rejuvenate them. Lifeseeds Nexus aims to support this goal by providing a comprehensive solution. Our unique formulation consists of four carefully selected ingredients that work synergistically to promote overall well-being and longevity. Let’s break it down:


Nicotinamide riboside (NR) is a form of vitamin B3, also known as niacin or nicotinamide. It is a precursor to NAD+ in the body, meaning it can be converted into NAD+ through specific enzymatic reactions. NR has gained significant attention in recent years due to its potential role in boosting NAD+ levels and promoting various health benefits.


Trimethylglycine (TMG) is an amino acid derived from plants that plays a crucial role in the methylation process for multiple biological functions. TMG helps maintain adequate levels of methyl groups, which is important as the body consumes methyl groups during the production of NAD+. TMG contributes to normal homocysteine metabolism.


Pterostilbene, closely related to resveratrol, is a powerful stilbenoid compound with antioxidant and anti-inflammatory properties. It is naturally found in blueberries and grapes, and its superior bioavailability enhances its efficacy. Combined with nicotinamide, pterostilbene activates sirtuins - enzymes involved in cellular processes and aging.

Grape Seed Extract

Grape seed extract is derived from grape seeds and contains potent antioxidants like proanthocyanidins. These antioxidants help combat free radicals and oxidative stress, benefiting overall health. Grape seed extract is recognized for its potential to support cardiovascular health, promote skin health, and enhance immune function.


NAD+ is directly related to the state of healthy aging.

As we age, our skeletal muscle function and metabolism decline. The molecular processes underlying and the role physical activity plays in age-related decline are largely unknown. However, in a groundbreaking study, researchers examined muscle metabolism in both young and older adults, including those who exercised regularly, had normal activity levels,...

Nicotinamide can improve vision in glaucoma patients.

  Nicotinamide can prevent nerve cell damage that leads to blindness in glaucoma. This is shown by the world's first clinical study in the field published in Clinical and Experimental Ophthalmology. The study was led by researchers at the Center for Eye Research Australia in collaboration with researchers at Karolinska Institutet and St. Erik's...

NMN supplementation enhances cardiovascular fitness.

A scientific study was recently carried out with the aim of discovering how supplementation with the NMN molecule can affect performance in runners. Results showed that NMN has a positive effect on the body’s endurance.   NMN – a precursor to NAD+ and short for Nicotinamide mononucleotide, is a molecule that...

Therapeutic Potential of NAD-Boosting Molecules.

The levels of NAD+ in our cells decrease as we get older, something that effects our metabolism and makes it easier to get sick. But research now shows that NAD-enhancing molecules can increase chances of a long, healthy life.   NAD+, short for Nicotinamide adenine dinucleotide, is a coenzyme that...

Frequently asked questions

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

    Our subscriptions are designed to offer convenience and flexibility without any long-term commitment. When you choose a subscription, you can establish a daily habit of using Nexus to enhance your overall health. We will automatically ship your products at your chosen interval (every 10, 14, or 30 days) so you never run out. You have full control over your subscription and can easily make changes or cancel anytime through your account.

    If you prefer to try Nexus before committing to a subscription or want to gift it to someone, our one-time purchase option is available. This allows you to experience the benefits of Nexus without any ongoing subscription. It's important to note that it may take up to 2 months for your body to fully utilize the additional NAD+ from Nexus and experience its benefits.

    Whether you choose a subscription or a one-time purchase, our goal is to support your health journey and provide you with high-quality products that contribute to your overall well-being.

  • Do you perform lab testing on your molecules?

    Absolutely. In addition to our rigorous in-house lab tests, every batch undergoes third-party testing conducted by Laboratory Testing Services at Intertek. These tests verify the purity of our products, ensuring a minimum purity level of 99% and the absence of any heavy metals. Detailed test results are available upon request.

  • When is the best time to take Nexus?

    The best time to take Nexus is in the morning with a meal that includes healthy fats. This allows for better absorption and utilization of the nutrients in Nexus. Research has shown that our body's NAD+ levels follow a circadian rhythm, peaking during the waking hours. By taking Nexus in the morning, you can align the increase in cellular NAD+ levels with your body's natural rhythm, maximizing its benefits. It's recommended to avoid taking Nexus before bedtime to prevent any potential disruption to your sleep.

    Consistency is key, so establishing a regular daily routine for taking Nexus will help maintain optimal NAD+ levels and support your overall well-being. Start your day off right by incorporating Nexus into your morning routine for a healthy and energized start.

  • What dose should I take?

    To experience the potential benefits of Nexus, we suggest beginning with our recommended dose of two capsules each morning. This dose contains 300mg of Nicotinamide, a level that has shown positive results in various clinical studies, increasing NAD+ levels by approximately 40-50%. Remember, consistency is key in maintaining optimal results, so it's important to establish a regular routine and take Nexus consistently.

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

    The timeframe for experiencing the effects of Nexus can vary depending on individual factors and dosage. In our ongoing Nexus studies since 2020, a significant number of participants have reported noticeable effects within 1-2 months. Enhanced energy and endurance are among the initial benefits noted by users.

    Research shows that NAD+ levels start to rise from day one and reach their dose-dependent peak after two weeks of consistent Nicotinamide usage, maintaining elevated levels as long as the product is continued.

  • Is it possible to open the capsules if I have difficulty swallowing them?

    Absolutely! We understand that some individuals may find it challenging to swallow capsules. In such cases, you have the option to open the capsules and conveniently mix the contents with your preferred food or beverage. This method allows for easier ingestion and ensures that you can still benefit from the product's ingredients and their intended effects on your health. Whether you choose to mix it with a smoothie, yogurt, or any other suitable medium, this alternative approach provides a practical solution for those with difficulty swallowing capsules.
