I am 83+ and have been a diabetic for almost 30 years and have undergone two angioplasty procedures in 2009 and 2016. I started consuming ProArgi9+ which is distributed by Synergy in Malaysia in April in 2019. I switched to NiOx Health's Nitric Oxide Infusion which has the additional L-citrulline and L-malate in early 2022. Besides improving my heart and vascular health and keeping my diabetes in check, my kidney function, which was at threshold level, has significantly improved. I enjoy the natural flavor of both the Green Apple and also the Cranberry Infusion. (Dr Ho Chai Yee)
