Do the math: one tub is 30 servings — a full month of daily energy at $0.83 a day. A canned energy drink habit at about $4 a can runs roughly $120 a month for the same 30 days.
The Dr.K Fuel story
As a Gastroenterologist doctor, I wanted an energy and hydration product that was healthier than many other options I was seeing on the market.
I didn't set out to create another energy product. I created the product I wanted to use myself. I wanted a daily formula that combined clean energy, hydration and focus in one convenient drink — formulated with natural caffeine from green tea, L-Theanine, electrolytes from Himalayan salt, vitamins and monk fruit, no artificial sweeteners.
Whether you're heading into work, starting a long shift or simply need to stay energized through a demanding day, Dr.K Fuel was created to help fuel you through it. Every batch is third-party tested — contact us for further information.
