A process for making wax prills containing one or more nicotinyl riboside compounds selected from the group consisting of nicotinamide riboside (NR, I), nicotinic acid riboside (NAR, II), nicotinamide mononucleotide (NMN, III), nicotinic acid mononucleotide (NaMN, IV), reduced nicotinamide riboside (NRH, V), reduced nicotinic acid riboside (NARH, VI), NR triacetate (NRTA, VII), NAR triacetate (NARTA, VIII), NRH triacetate (NRH-TA, IX), NARH triacetate (NARH-TA, X), and salts or mixtures thereof;
- comprising the steps of:
- (a) preparing a mixture of a nicotinyl riboside and a hydrogenated oil selected from sunflower oil or palm oil;
- (b) spray melting the mixture at a temperature below about 90° C. and a flow rate of at least about 4 kg/hour;
- (c) allowing solidification of the sprayed mixture in cold air to provide generally spherical wax prills;
- and
- (d) isolating the generally spherical wax prills.
