This is a comprehensive vitality supplement containing maca, zinc, citrulline (which converts to arginine in the body), vitamins, and minerals. Made in Japan with a balanced formulation. We offer an affordable price, making it easy to take daily, so we've made a great value set of 5 months' worth. While it doesn't work immediately, as is the case with other supplements, your body will adjust with continued use. It's also important to add it to your daily diet and use it to supplement any deficiencies. Citrulline, which is metabolized into the energy component arginine, is an amino acid that is more efficiently absorbed by the body than arginine alone. In addition, we have blended ingredients beneficial for the body such as soft-shelled turtle, red ginger, Korean ginseng, and tongkat ali, setting us apart from products that only feature maca and arginine. This is a comprehensive supplement for a healthy daily life, containing ingredients effective for male function such as maca and zinc, as well as essential vitamins. Due to the rich blend of ingredients, it is effective not only for men but also for women. The expiration date is December, so we recommend purchasing it soon.
