NutriFitt | Silence | 21 Servings

NutriFitt Silence is a fully disclosed, non-melatonin sleep and recovery powder built around a smart formulation philosophy: reduce neurological overactivation, improve sleep onset, and support the quality of overnight recovery without leaning on a blunt hormonal hammer. That matters. A lot of sleep products are either underdosed botanical blends or melatonin-heavy knockouts that can leave some users feeling foggy the next morning. Silence takes a different route by stacking amino acids, minerals, neurotransmitter support, and standardized botanicals at doses that largely align with the literature.

The backbone starts with L-Glycine at 3,000mg, which is the exact dose most often used in sleep research. Glycine acts as an inhibitory neurotransmitter and also influences thermoregulation, a key factor in sleep initiation. In practice, this is one of the best-supported ingredients in the formula for helping the body transition into sleep while improving next-day perceived recovery. Magnesium is delivered as magnesium bisglycinate chelate, with 160mg elemental magnesium from a 1,000mg chelate source. Bisglycinate is one of the best forms for nightly use because the glycine chelate improves absorption and avoids the laxative effect common to oxide forms. The 160mg elemental dose is meaningful, though below the full 310-420mg daily intake range, so it works best as a nightly contributor rather than a complete daily magnesium strategy by itself.

GABA is dosed at 1,000mg, well above the common 100-300mg supplemental range. Oral GABA research is mixed because of long-running blood-brain barrier debates, but human and mechanistic data still support calming effects through gut-brain signaling, neuroinflammatory modulation, and reduced stress perception. Subjectively, this is the ingredient most likely to create that “volume turned down” feeling. L-Theanine at 300mg sits comfortably inside the strong clinical range and is one of the formula’s most reliable anxiolytic pieces, helping reduce mental chatter by modulating glutamate signaling while increasing alpha-wave activity.

The serotonin-to-melatonin pathway is supported from multiple angles. Vitamin B6 is provided as pyridoxal-5-phosphate, the active coenzyme form, at 10mg. That matters because P5P is directly involved in neurotransmitter synthesis. It pairs intelligently with 250mg L-tryptophan and 100mg 5-HTP. Tryptophan is a precursor upstream of 5-HTP, serotonin, and melatonin, while 5-HTP sits one step closer to serotonin production. On paper, 250mg tryptophan is below the 1-5g range commonly studied alone, but here it functions as part of a broader neurotransmitter support network rather than a standalone hero dose.

The botanical side is unusually sophisticated for the category. Chamomile extract at 250mg standardized to 1.2% apigenin adds traditional calming support, and the formula doubles down with an additional 50mg apigenin—right at the low end of the emerging 50-200mg research range. InoZyn™ at 150mg combines passion flower and Baikal skullcap, both associated with GABAergic calming effects, and this dose matches the intended use range for the trademarked blend. Zenha® ashwagandha at 120mg lands at the bottom of the clinically useful range and is included for HPA-axis and cortisol regulation rather than sedation. KannaEase™ at 25mg is a notably modern touch: a standardized Sceletium extract that works as an SRI and PDE4 inhibitor, helping smooth stress reactivity and mood without acting like a sedative.

As a system, Silence is designed in layers: magnesium, glycine, GABA, and theanine calm the nervous system directly; tryptophan, 5-HTP, and P5P support neurotransmitter conversion; apigenin, chamomile, InoZyn™, Zenha®, and KannaEase™ broaden the pathway coverage from GABAergic relaxation to stress-response control. Transparency is a major strength here—no proprietary blends, every active disclosed, and several trademarked ingredients included at meaningful doses. Expect the first use to feel like a reduction in tension rather than a forced knockout. Over 2-4 weeks of consistent use, the formula should deliver its best results through more reliable sleep onset, less bedtime restlessness, and better next-day recovery quality.
