Efectiv Nutrition Sleep Formula Powder is a structured pre-bed wind-down stack built for trainees who want sleep-onset and sleep-quality support without melatonin. Each 8g serving delivers 3000mg of L-glycine, 1750mg of magnesium bisglycinate, 500mg of lemon balm extract and 450mg of valerian root extract in a powder format that mixes into water 30 minutes before bed. The 240g tub provides 30 servings.
L-glycine at 3g is the dose used across the sleep-research literature for sleep-onset latency and subjective sleep quality improvements. Magnesium bisglycinate at 1750mg compound provides a meaningful elemental magnesium dose for muscle relaxation and the EFSA-authorised reduction of tiredness and fatigue claim. Lemon balm at 500mg is the traditional herbal extract used in European wind-down formulations. Valerian root at 450mg is the longest-used herbal sleep aid in European supplementation, with research support for sleep-onset improvements.
What separates Sleep Formula Powder from a melatonin capsule is the route. Melatonin works on the circadian system; this formula works on the relaxation and muscle-tension side of sleep onset. Many trainees find melatonin gives morning grogginess - the glycine, magnesium and herbal route generally doesn't. The powder format also lets you dose with water as a structured pre-bed ritual rather than swallowing a capsule.
Sleep Formula Powder suits trainees who train in the evening and struggle to wind down for sleep, lifters running high training volumes who want magnesium support, and anyone who has tried melatonin and disliked the morning effect. Not the right pick for trainees who specifically want melatonin-based circadian support or who prefer capsule formats over powders.

Frequently Asked Questions
How do I use Efectiv Sleep Formula before bed?
Mix one 8g scoop with 200 to 300ml of cold water and drink it 30 to 60 minutes before bed. Pair it with a consistent wind-down routine (dim lights, off the phone, and a regular bedtime) so the supplement is supporting good habits rather than carrying them. There is no antihistamine or melatonin in the formula.
How does Sleep Formula compare to Efectiv Zylaria capsules?
Sleep Formula is a 6-ingredient nightly drink combining L-glycine, magnesium bisglycinate, lemon balm, valerian root, L-theanine and L-tryptophan. Zylaria is a capsule providing 500mg Xylaria nigripes mushroom extract. Pick Sleep Formula if you want a multi-ingredient drink as part of a wind-down ritual; pick Zylaria if you prefer a single-ingredient capsule you can add to an existing routine.
Is Efectiv Sleep Formula suitable for nightly use?
The ingredients are naturally occurring amino acids, magnesium and plant extracts, and the formula is designed for nightly use. If you are pregnant, breastfeeding, taking prescription medication, or have a pre-existing health condition, check with a qualified healthcare professional before use. It is not a substitute for a balanced diet or for addressing underlying sleep issues with a doctor.

Not very effective for me in terms of a deep sleep night, still waking 2-3 times. Also, it gave me an upset stomach so stopped taking this supplement after 3 consecutive days.

Great sleep aid without the hangover effect.
Really helps with a good night’s sleep after a hard workout when everything aches. No hangover and ready for the gym again the next day!
