Add a tablespoon of this beet root powder to your Great Lakes Gelatin to stave off any cow-hoof flavor. Amelia Boone, mentioned above, uses this for pre-race and pre-training endurance benefits, but I'm much harder-core: I use it to make tart, low-carb gummy bears when fat Tim has carb cravings.

I was introduced to UCAN and its unique carbohydrate SuperStarch by my good friend—and listener favorite—Dr. Peter Attia, who said there is no carb in the world like it. I have since included it in my routine, using UCAN’s powders to power my workouts, and the bars make great snacks. Extensive scientific research and clinical trials have shown that SuperStarch provides a sustained release of energy to the body without spiking blood sugar. UCAN is the ideal way to source energy from a carbohydrate without the negatives associated with fast carbs, especially sugar. You avoid fatigue, hunger cravings, and loss of focus. Whether you’re an athlete working on managing your fitness or you need healthy, efficient calories to get you through your day, UCAN is an elegant energy solution.

Ever since I wrote The 4-Hour Body, starting my day with ~30 grams of protein has been an essential part of my routine. I’ve been using Ascent’s whey protein for the last several years, and I recently tried their new plant-based protein. I’ve experimented with many other plant-based proteins, and most compromise on taste or efficacy, but Ascent Plant Protein is delicious and provides 25 grams of protein with 4 grams of BCAAs to support muscle health. To ensure their product tastes great, Ascent verified it with third-party consumer research, and it won on taste and texture against the market leader. What’s more, it’s made from organic, real-food sources like organic pea, pumpkin, and sunflower and contains zero artificial ingredients, artificial sweeteners, or added sugars.

I’ve stocked up on boxes and boxes of LMNT, and I usually use 1–2 packs per day to add electrolytes to prevent dehydration symptoms like headaches, muscle cramps, and fatigue. I add electrolytes for many reasons: because I over-hydrate compulsively while stuck at a laptop (which dilutes electrolytes and leads me to feel tired), because I’m on a low-carb diet, because I’ve lost electrolytes through exercise, dry winter climates, etc. It’s simply cheap hydration insurance that tastes great. Each serving of LMNT delivers a meaningful dose of electrolytes without the garbage—no sugar, no artificial ingredients, no coloring, no junk. My favorite flavor is Citrus Salt, which, as a side note, you can use to make a kick-ass, no-sugar margarita.

I’ve also been using Momentous Creatine, and while it certainly helps physical performance, including poundage or wattage in sports, I use it primarily for mental performance (short-term memory, general podcasting, etc.). Their products are third-party tested (Informed Sport and/or NSF-certified), so you can trust that what is on the label is in the bottle… and nothing else.

Momentous offers high-quality supplements and products across a broad spectrum of categories, and I’ve been testing their products for months now. I’ve been using their magnesium threonate, apigenin, and L-theanine daily, all of which have helped me improve the onset, quality, and duration of my sleep. Momentous Sleep conveniently delivers all three in one single blend to help prime your body for sleep and help you build a powerful nighttime routine. I’ve also been using Momentous Creatine, and while it certainly helps physical performance, including poundage or wattage in sports, I use it primarily for mental performance (short-term memory, etc.) Their products are third-party tested (Informed-Sport and/or NSF-certified), so you can trust that what is on the label is in the bottle and nothing else. No matter what your fitness goals are, or what you want to achieve this year, Momentous is on a relentless quest to help you get there.
