Our Liposomal NMN capsules are encased in liposomes for increased absorption and protection against stomach acid. Purovitalis NMN is sourced and manufactured in Europe within GMP-certified facilities. Third-party tested for purity and heavy metals, we offer you 99% Nicotinamide Monucleotide. Because our Liposomal NMN comes from Europe, we are the first company not to focus on China. We reduce our carbon footprint without compromising the high purity standards we have set for ourselves. For our purity results, please refer to our third-party lab test certificates. Our Liposomal NMN supplements are daily support to embrace each new day full of energy and with confidence.
