5% Nutrition | 5% Knocked The F Out | 30 Servings

5% Nutrition Knocked The F Out is a fully disclosed sleep formula built around a simple idea: falling asleep is only one part of the equation. A good nighttime formula also has to help downshift the nervous system, quiet mental overactivity, and support the neurotransmitter pathways involved in relaxation and sleep initiation. That is the strategy here. Instead of relying on melatonin alone, this formula layers melatonin, inhibitory neurotransmitter support, calming botanicals, and serotonin-pathway precursors into one powder.

The anchor ingredient is melatonin at 8mg. Melatonin is one of the most evidence-backed sleep ingredients in the category, with meta-analytic support for improving sleep quality and helping regulate the body’s sleep-wake timing. This is a strong dose by category standards. Many sleep products sit in the 1-5mg range; 8mg is designed to be felt, especially by people who have trouble initiating sleep. For some users that will be a major strength. For others, it also means this is not a “light” sleep formula.

GABA is included at 750mg. The evidence on oral GABA is more mixed than melatonin because its ability to cross the blood-brain barrier is debated, but human research does support relaxation effects and shifts toward calmer brain-wave activity under stress. At 750mg, this sits in a meaningful practical range for a sleep formula even if the mechanistic literature remains imperfect. Subjectively, this is the kind of dose users typically associate with taking the edge off a wired, overstimulated state.

The formula also supports the serotonin-to-melatonin side of sleep physiology with 500mg L-tryptophan, 30mg 5-HTP, and 2mg vitamin B6. Tryptophan is the upstream amino acid precursor to serotonin, and evidence syntheses suggest doses of 1g or more are where sleep-latency effects become more consistent. That means 500mg is directionally useful but below the strongest standalone research range. 5-HTP at 30mg is similarly modest relative to common standalone products, but it complements tryptophan by working one step closer to serotonin. Vitamin B6 matters because it serves as a cofactor in this conversion pathway.

The botanical calming layer is one of the stronger parts of the formula. Chamomile extract at 650mg and lemon balm extract at 500mg are robust inclusions for a mainstream sleep product, and passionflower at 200mg adds another traditional relaxation herb commonly used for nighttime formulas. Together, these herbs are designed to soften physical and mental tension rather than simply force sedation.

L-theanine is here at 75mg. That is below the 200mg dose used in strong acute stress research, so it is better viewed as a supporting ingredient than a headline driver. Inositol at 500mg is also well below the gram-level amounts used in many clinical settings, but it still fits the formula’s “calm the mind” architecture.

The most unusual inclusion is L-tyrosine at 750mg, plus 75mg phenylalanine. These amino acids are more commonly associated with catecholamine support and stress resilience than with sleep. In a nighttime formula, they are non-standard. Some users may appreciate the mood-stabilizing, stress-buffering intent, but from a strict sleep-formulation perspective, they are less intuitive than additional theanine, magnesium, or glycine would have been.

What makes this product competitive is its systems-based design and full transparency. No proprietary blend, no hidden doses, and enough clinically relevant actives to create a real nighttime effect. Expect the first serving to feel strongest through melatonin plus the calming herbal/GABA stack. Over 2-4 weeks, the biggest benefit is routine consistency: using the same pre-bed signal nightly so your body learns when it is time to shut down.
