TRU NIAGEN Patented NAD Supplement for Brain Function, Anti Aging & Cell Regeneration, 300mg Niagen, 30 Servings | Supports Cellular Energy, Muscle | Nicotinamide Riboside (NR) Take 1 Daily | 1 Bottle

Main Highlights

A COMPLETE ANTI AGING SUPPLEMENT - Support whole body wellness and boost cellular energy with Tru Niagen, a patented NAD+ supplement that supports the 37.2 trillion cells in your body Tru Niagen helps the production of nicotinamide adenine dinucleotide to promote healthy cell activity and can help reduce aging-related health concerns. Tru Niagen is clinically proven to be one of the safest and most efficient boosters of NAD+ levels, shown to increase NAD+ over 50% in just 2 weeks with daily use.
VITAL FOR CELLULAR ENERGY - Tru Niagen supports your ability to stay healthy by boosting NAD+ levels, which naturally decline as you age. NAD+ is vital for cells to function and repair. It supports brain health, muscle health and recovery, heart health, cellular energy and repair, and lifestyle stress management. Patented Tru Niagen is more efficient at raising NAD+ than other NAD+ precursors such as NMN, niacinamide, or niacin.
TRU STORY: WITHOUT NAD, CELLS DIE - Our bodies naturally decrease in NAD+, with up to a 65% decline between ages 30-70. Effects of metabolic stress and time on your cells can accelerate aging, which leads to many health concerns. Everyones body, stressors, and goals are different. Most clinical studies have used 1000mg daily. NAD+ decline begins in your 30s, it's recommended to start with 300mg daily. As you age and are exposed to more metabolic stressors, such as environmental factors or immune challenges, you can move to 1000mg daily. Always check with your healthcare provider for the best dose for you.

Toniiq

Toniiq NMN Supplement 1200mg - Third Party Tested Stabilized Capsules - 98% Highly Purified for NAD + - 60 Capsules Nicotinamide Mononucleotide Booster Supplement

9% Off

Main Highlights

The Highly Purified form of Nicotinamide Mononucleotide: Toniiq NMN capsules contain 1200mg of the highest quality nicotinamide mononucleotide in each serving ethically sourced and produced using an extraction process to ensure 98% purity.
Fully Stabilized: NMN typically needs to be kept cold (fridge or freezer) because of its short shelf life. Our NMN comes in a completely shelf-stable non-refrigerated form and is packaged and sold in black sealed bottles that block light, moisture, and oxygen to ensure maintained and maximum potency.
Highly Purified: Nicotinamide Mononucleotide has amazing health benefits. However, purity has always been a major challenge for this super-nucleotide; something most other nmn supplements dont provide as it requires an extra step (and expense) in the manufacturing process. At 98% pure nicotinamide mononucleotide, our NMN supplement capsules provide some of the purest and most potent NMN available.
Quality, First, and Foremost: Toniiq products are produced in a GMP-certified state-of-the-art manufacturing facility right here in the USA.
Each Batch is Individually Tested: We test each batch both ourselves and through a third-party independent laboratory to ensure our ingredients contain the correct standardized level of purity and active ingredients. We also test each batch for any possible additives, contaminants, and impurities to ensure the highest level of quality.
