WHY STACK
YOUR IMMUNITY?
Built for people who can't afford to get sick. Here's what's working against you, how Stackt fights back, and how to use it.
WHAT'S WORKING AGAINST YOU
Your immune system faces more pressure than most people realize. Five of the biggest threats:
Intense or prolonged exercise temporarily weakens your immune system, creating a window where your body is more vulnerable to getting sick than usual called Immunodepression. Athletes, runners, and anyone with an active routine feel this hardest.
Sustained stress slowly weakens your body's ability to fight off infection. It happens gradually, which is why most people don't notice until they're already run down. Founders, healthcare workers, and anyone running on adrenaline know the pattern.
Disrupted or insufficient sleep weakens your immune defense and slows recovery. The effects are long-lasting. A few good nights don't undo it. Shift workers, new parents, and overnight schedules carry the heaviest debt.
Airports and planes hit your immune system from two directions at once. You're sealed in recycled cabin air with hundreds of strangers right when dehydration and timezone shifts are wearing your defenses down. Jet lag alone can knock your immune baseline off for days, even if you don't catch what's going around.
Less sunlight, colder air, more time indoors. Your immune system faces its biggest annual test between November and the end of winter, and most people aren't prepared for it.
HOW STACKT FIGHTS BACK
For every threat, a clinically dosed response. Backed by peer-reviewed research.
Hard training drains your body's glutamine, which your immune cells rely on as fuel. Stackt's 2,500mg of L-Glutamine refuels the system. A clinical study on athletes after exhaustive exercise showed glutamine supplementation significantly reduced the rate of post-training infections.
When you're constantly stressed, your body's stress system stays switched on, gradually wearing down your immune defenses. Stackt's 250mg of Panax Ginseng works on the same system, helping your body manage stress hormones so immune function stays steady under pressure.
Sleep and immune function are directly connected. Sleep loss raises your risk of getting sick and weakens how your body responds when it does. You can't out-supplement bad sleep, but Stackt's daily clinical doses of Vitamin C, Vitamin D3, and Zinc support the immune cells that take the biggest hit when you're underslept.
Travel stacks crowded cabins, recycled air, dehydration, and disrupted sleep into the same 12-hour window. No single ingredient handles all of it. Stackt's daily protocol delivers Vitamin C, Vitamin D3, Zinc, L-Glutamine, and Panax Ginseng in clinical doses every day, so you're not relying on whatever you can grab in an airport terminal.
Less sunlight means lower Vitamin D, and most North Americans are deficient even before winter hits. Stackt's 1,000 IU of Vitamin D3 keeps your immune cells running during the months when your body needs it most. Without enough Vitamin D, your immune cells can't do their job properly.
