Why NADclinic NAD+ is Best-In-Class NADclinic NAD+
“The Gold Standard” Always Natural, Always Pure…
Crystal Clear NAD+ v Yellowish Tinted NAD+
There is a common misconception typically promoted by unlicensed NAD+ manufacturers, who use synthetic products and stabilisers to produce clear inferior NAD+, is that any yellowish tint in NAD+ signals degradation. THIS IS NOT TRUE. Scientific evidence and industry standards do not support this claim and in-fact advocate the opposite.
Degradation vs. Natural Colour
True NAD+ degradation is a chemical breakdown caused by prolonged exposure to heat, light, or moisture. A soft yellow tint is not degradation, it’s a normal, natural feature of high-purity NAD+.
In naturally enzyme-produced NAD+, a slight yellow hue can occur from minimal, harmless redox variation (trace NADH formation) and natural batch-to-batch raw-material differences. You cannot judge NAD+ quality by colour alone, integrity and potency must be confirmed through validated UKAS accredited lab tests such as HPLC or UV-Vis.
That’s why a yellowish NAD+ solution doesn’t signal impurity or reduced strength. Validated GMP suppliers produce NAD+ at 98%+ purity with full stability under standard storage conditions, and regulatory monographs allow colour variation when assay results confirm identity and potency.
NADclinic’s NAD+ is naturally enzyme-produced and intentionally free from synthetic stabilisers like mannitol, solvents, or fillers. The colour you see is a visual hallmark of pure, additive-free NAD+ in its true form. Every batch is GMP-manufactured, handled under cold-chain conditions, and independently tested in NHS/UKAS-accredited labs for purity, sterility, and stability, ensuring consistent clinical-grade performance worldwide.
