Yes! Freedom from tiredness

Feeling spent? The culprit may be a shortfall of a key energy molecule (called NAD) that helps power every cell in the body to burn more fat for fuel. Harvard researchers say production of this energizing dynamo can drop in half by age 55— but luckily, a few easy steps solve the problem and make your energy levels soar! Reach for apples

That apple you enjoyed earlier? It’s working wonders to boost your pep! Researchers reporting in the journal

Cell Metabolism say a nutrient in apples called quercetin shores up your levels of the energy molecule. Enjoying two small crunchers a day delivers the feel-great perks— or you can get the benefits by eating two cups of quercetin-rich vegetables daily. Top picks include cruciferous veggies, bell peppers and leafy greens.

Take the stairs

No gym? No problem! Walking up one flight of stairs a day is all the exercise you need to feel revitalized, research from Hungary suggests. That’s because short daily bursts of activity prompt cells to release as much as 57% more of the energy molecule. Study co-author Erika Koltai, PH.D., says that’s why exercise makes us feel more energized, instead of spent.

Get a boost with B’s

B vitamins give so many people a significant mental and physical energy boost that nutritionists now recommend taking B’s with breakfast so they don’t disrupt your sleep! Take a basic B-complex supplement daily and British researchers say you’ll boost your levels of the energy molecule enough to feel up to 33% more youthful in just 24 hours. Important: Always check with your doctor before taking supplements.

Steam and stir-fry

Here’s a wonderful reason to take a break from cooking: Eating a daily cup of fresh vegetables that are raw or heated up just briefly (think stir-frying or quick steaming) can increase your body’s production of the energy molecule by up to 35%, researchers from Canada report. And that can have you feeling unstoppable in no time at all!
