The invention discloses a NMN-containing capsule and a preparation method thereof. The capsule comprises NMN nanoparticles, a first layer of capsule layers and a second layer of capsule layers that sequentially coat the NMN particles from the inside to the outside; wherein, the first layer of capsules The layer includes the following components in parts by weight: 4-8 parts of sunscreen, 1-3 parts of stabilizer, 1-3 parts of antioxidant, 8-15 parts of sustained release agent and 8-15 parts of enteric solvent; the second layer of capsules includes The following components in parts by weight: 6-12 parts of sunscreen agent, 3-5 parts of stabilizer, 4-7 parts of antioxidant, 10-20 parts of slow release agent and 12-25 parts of enteric solvent. The present invention is coated with two layers of capsule layers outside the NMN nanoparticles, which can avoid the influence of moisture, air and light on the NMN, improve the stability of the product, and facilitate the long-term storage of the NMN product. |
