Let's Talk Energy & Calm

The questions women ask us most.

How soon will I feel something? +

Magnesium tops up what you've been missing, so it builds rather than hits like a stimulant. Most women say the two-week mark is when it clicks — easier sleep, steadier energy, calmer under stress.

Will it upset my stomach like other magnesium? +

That's the #1 reason women quit magnesium — because they were sold cheap oxide. This leads with glycinate, the gentle, absorbable form. Taken with food, it sits easy.

Can I take this in perimenopause or menopause? +

It was built for exactly this stage. The magnesium, D3, K2, B's, ashwagandha and inositol support stress, sleep, energy and hormone balance. If you take medication or have a condition, check with your doctor first.

What if I have the MTHFR gene? +

Then the B vitamins in most supplements do little for you. This uses methylated B's — one of the few forms your body can absorb if you carry the variant.

Why not just buy the ingredients separately? +

Buy them one by one and you're past $100 — and swallowing a handful of pills daily. This is all of it in one bottle, two capsules, four months.

How many a day, and how long does it last? +

Just 2 capsules a day. Each bottle is 60 capsules — a full 1-month supply.

What Happens In Your First 30 Days

Two capsules a day. Here's how it tends to unfold.

Days 1–7

THE FIRST FEW NIGHTS

You start winding down easier at night, and sleeping through instead of staring at the ceiling at 3am.

Days 8–14

STEADIER DAYS

The two-week mark is when it clicks. Energy stops crashing and stress stops grabbing you the way it used to.

Days 15–30

FEELING LIKE YOU AGAIN

The wired-but-tired fog lifts. Calmer, clearer, more like yourself, on just two capsules a day.
