Why This Stack Works
Poor sleep costs the average adult 2.5 hours of deep sleep per night — the stage where growth hormone releases, memories consolidate, and inflammation clears. This stack targets 3 independent mechanisms simultaneously: GABA modulation (Apigenin), magnesium-dependent enzyme activation (Glycinate), and cortisol suppression (KSM-66). No single supplement does all three.
The NordVital Sleep Stack
Magnesium Glycinate — 400mg
Take 1 hour before bed. The glycinate chelate is 4× more bioavailable than oxide.
NordVital Score: 9.4/10 | TIER S
Ashwagandha KSM-66 — 300mg
Take with magnesium. Reduces cortisol by 27.9%, enabling faster sleep onset.
NordVital Score: 8.7/10 | TIER A
Apigenin — 50mg
Take 30 min before bed. GABA-A agonist — the same mechanism as sleep medications but gentle.
NordVital Score: 8.0/10 | TIER A

Frequently Asked Questions
Can I take all three together?
Yes — they work through different mechanisms with no known interactions. Magnesium + Ashwagandha is a well-studied pairing. Adding Apigenin is safe and additive.
Will I feel groggy in the morning?
None of these cause next-day grogginess at recommended doses. Magnesium and Ashwagandha don’t accumulate. Apigenin at 50mg is mild — unlike pharmaceutical sleep aids.
How long until I notice results?
Apigenin and Magnesium can show effects in 1–3 nights. Ashwagandha’s cortisol reduction builds over 2–4 weeks. Most users report significant sleep improvement within 7 days.
