Discovering NAD+ and Tru Niagen for the first time? Tru Niagen 100mg allows you to ease into using our product and see how it works for you. The recommended daily serving is 300mg (and most of our consumers respond well to this), but you can start with less and track what you notice to find the amount that’s best for your body—you’re in total control of your NAD-boosting experience.

We’re all unique. With Tru Niagen 100mg, you can start your journey toward healthier aging at a serving size that’s right for you. NAD+ (nicotinamide adenine dinucleotide) is a coenzyme vital to all living organisms as it’s crucial in powering the 37.2 trillion cells in your body so they can function well. Your NAD+ levels decline as you age, especially between 40 and 60. Tru Niagen is a scientifically proven way to get those NAD+ levels up again and help you take back some of your former glory.

Feel free to start at just 100mg, and add more as you get comfortable. You might stick with that amount, or you might feel best taking 300mg, or you might want to take even more. Studies have shown a more pronounced boost in NAD+ levels from taking as much as 1,000mg daily, and Tru Niagen is safe to consume up to 2,000mg per day.
