Keto OS NAT Berry Blue (3s)

LIMITED SEASONAL RELEASE!!!

For blueberry lovers, this is your flavour! 

Buy this to try the flavour first before committing to full boxes on our Yesto.Pruvit.com/sg website!

P.S. Almost all our flavours come in Charged (caffeinated) and Caffeine-free formulas. The caffeine helps enhance ketone production in the body, as well as improve the exogenous ketone uptake into our cells. So it acts as a booster and is a little bit more potent than the caffeine-free. However it all really depends on your sensitivity to caffeine, as well as preference. The ketones will work well regardless of whether you want a boost or not. :)
