Why do you have 1000mg of NMN and 1000mg of Resveratrol?
We include 1000mg of NMN and 1000mg of Resveratrol in OneLife because research shows these dosages deliver the most effective results for longevity and cellular health. Studies demonstrate that 1000mg of NMN significantly raises NAD+ levels, enhancing cellular energy, muscle strength, and insulin sensitivity, especially in older adults. Doses below this, such as 250mg, show milder effects, particularly in energy and metabolism improvements. At 1000mg, NMN works synergistically with Resveratrol, which activates sirtuins, proteins linked to longevity, improving cardiovascular health and reducing inflammation. Together, these dosages provide optimal support for energy production, cellular repair, and overall vitality, ensuring you receive the full range of anti-aging benefits from both ingredients.
When should I take One Life?
OneLife is best taken in the morning to maximise the effects of NMN and Resveratrol, which work together to boost energy and cellular repair throughout the day. By starting your day with OneLife, you’ll replenish lost electrolytes, re-energise, and support longevity, making it the perfect foundation for optimal performance and well-being.
How does One Life support longevity and wellness?
OneLife supports longevity and wellness by boosting cellular health through NMN, which elevates NAD+ levels critical for DNA repair and energy metabolism, helping slow the aging process and enhance vitality. Resveratrol activates sirtuins, proteins linked to longevity, promoting healthy aging, reducing inflammation, and improving cardiovascular health. Together, NMN and Resveratrol enhance mitochondrial function, boosting energy and mental clarity. Additionally, OneLife replenishes essential electrolytes, supporting hydration, metabolism, and overall physical performance, making it a comprehensive solution for long-term wellness and vitality.
Why is the proper dose of electrolytes so important?
The right dose of electrolytes is crucial for maintaining hydration, muscle function, and energy levels. Electrolytes like sodium, potassium, and magnesium help balance fluids, support nerve signals, and prevent muscle cramps. Many products on the market contain less than half of the electrolytes needed, which can be dangerous, leading to dehydration, fatigue, and performance issues. First or Nothing’s Advanced Electrolyte System provides the optimal amount to ensure proper hydration and performance, especially for those with active lifestyles.
