Do you ever wake up feeling more tired than when you went to bed? Like your body has betrayed you overnight, and no amount of coffee can bring you back? If you're over 40 and feeling like you're constantly running on fumes, you're not lazy — you're likely dealing with perimenopause fatigue. And trust me, you're not alone.

For years, I thought I just needed to push through — more caffeine, stricter diets, more intense workouts. But none of that worked. Why? Because my hormones were shifting, and my energy levels were paying the price.

Today, I’m sharing the 7 real strategies that helped me stop dragging through the day… and the one supplement that gave me my spark back.

1. Balance Your Blood Sugar—Even If You’re “Healthy”

Perimenopause can cause more insulin resistance, meaning your energy crashes harder after meals. The solution? Eat meals that balance protein + fiber + healthy fats. Think: a veggie omelet with avocado, or salmon over greens with olive oil. Skip the carb-only breakfasts. They’re energy killers.

2. Get Light First Thing in the Morning

Your circadian rhythm is off during perimenopause. That’s why you're wired at night and sluggish in the morning. The fix? Within 30 minutes of waking up, go outside or sit by a sunny window. It tells your brain, “Time to be alert!” Bonus: it helps with sleep too.

3. Don’t Skip Strength Training

Cardio burns calories, but strength training builds energy. Lifting weights boosts testosterone and growth hormone — both of which dip in your 40s and 50s. You don’t need to become a bodybuilder — just 2 sessions a week can work wonders for your stamina and metabolism.

4. Cut Out the Silent Energy Killer: Blue Light at Night

Blue light from phones, tablets, and TVs suppresses melatonin. And poor sleep = chronic fatigue. Set a “tech curfew” 1 hour before bed, and switch to amber lighting. You’ll sleep deeper, wake up less, and actually feel rested in the morning.

5. Support Your Adrenals with Adaptogens

Perimenopause = more cortisol chaos. Adaptogenic herbs like ashwagandha, rhodiola, and holy basil help your body adapt to stress. These herbs don’t sedate you — they bring balance. You can add them via teas or supplements (check my favorite below).

6. Hydrate — But Not Just With Water

If you’re drinking tons of water and still feel drained, you might need minerals, not just H2O. Try adding electrolytes or trace minerals to one glass a day. You’ll be shocked how fast your brain fog and fatigue improve.

7. Fix Your Magnesium Deficiency (This Changed Everything)

Here’s the truth: most women over 40 are magnesium deficient… and it shows up as exhaustion, anxiety, insomnia, and even depression.

For me, magnesium was the game changer.

Not all magnesium is created equal. I use and recommend the Magnesium Zinc supplement from Revive After 40 Shop — it’s clean, gentle on the stomach, and specifically formulated for women in perimenopause. Within a week, I noticed:

  • Fewer energy crashes

  • More stable moods

  • Deeper sleep

  • And an actual desire to get off the couch!

👉 If you try one thing from this list — make it magnesium. Your nervous system will thank you.

Ready to Feel Like Yourself Again?

Perimenopause doesn’t have to mean fatigue is your new normal. These 7 strategies aren’t quick hacks — they’re real shifts that work with your body, not against it.

Start small. Add one new habit this week. Try the supplement I trust. And know that you’re not broken — you’re just changing.
