Understand What Powers C2K
At C2K, we believe that knowledge is the first step to lasting wellness.
Here, you can explore the science behind our ingredients — how they work, why they matter, and what makes C2K different.
Fucoidan
Fucoidan is a natural compound extracted from brown seaweed, celebrated for its immune-boosting and cell-regenerating properties. It supports the body’s ability to protect against inflammation, promote cellular repair, and maintain overall vitality.
C2K Fucoidan is formulated with high-purity extract standardized for potency and produced under FDA, GMP, and NSF standards in the USA.
NMN / NAD⁺
Nicotinamide Mononucleotide (NMN) is a vital precursor to NAD⁺ — a molecule essential for energy metabolism and DNA repair. As we age, NAD⁺ levels decline, leading to fatigue and slower cellular recovery.
C2K NAD⁺ supports natural energy production, promotes healthy aging, and helps the body maintain optimal vitality.
