NingXia Zyng will be back in stock from 1 October 2018, while stocks last. As Young Living’s greatest priority is maintaining safe, natural, chemical-free products, NingXia Zyng is free from preservative and only contains natural stabilizer to sustain the formulation. As such, the shelf life of this product is shorter than other average carbonated drinks in the market, therefore this batch of NingXia Zyng will expire on 3 November 2018.
