$29.99$0.49/srv 60 servings

Sleep quality and creatine target two different recovery bottlenecks. Superhuman Sleep helps you get into deeper, more restorative rest, while creatine supports phosphocreatine replenishment, strength output, and training adaptation over time.

Take creatine daily anytime; take Superhuman Sleep 20-30 minutes before bed.

Standalone Magnesium GlycinateSLEEP RECOVERY

This formula uses a strong magnesium form but only provides 40mg elemental magnesium. Adding a standalone magnesium glycinate can deepen the mineral side of the formula without duplicating the glycine, tryptophan, and melatonin core.

Take with or alongside Superhuman Sleep in the evening.

Casein ProteinPROTEIN/RECOVERY

If your goal is overnight recovery and muscle retention, slow-digesting casein pairs well with a nighttime sleep formula. Better sleep plus sustained overnight amino acid availability is a smart combination for hard-training athletes and body composition phases.

Take casein 30-60 minutes before bed; use Superhuman Sleep 20-30 minutes before bed.

Electrolyte/Hydration FormulaHYDRATION ELECTROLYTE

Poor hydration can worsen nighttime cramping, sleep disruption, and next-day recovery. Pairing a daytime hydration product with a nighttime sleep formula creates a fuller recovery protocol rather than relying on sleep support alone.

Use hydration support earlier in the day or around training; use Superhuman Sleep before bed.

Full Product Description Article

Alpha Lion Superhuman Sleep is a fully disclosed nighttime recovery formula designed around one core idea: better sleep quality drives better performance, better body composition outcomes, and better day-to-day recovery. Instead of relying on a single heavy sedative pathway, this formula layers amino acids, neurotransmitter support, adaptogens, minerals, and a moderate 2mg melatonin dose to address the full sleep equation: calming the mind, improving sleep onset, supporting sleep architecture, and reinforcing overnight recovery.

The anchor ingredient is L-Glycine at 3,000mg, which is right in the range commonly used in sleep-support formulations. Glycine functions as an inhibitory neurotransmitter and is also involved in thermoregulation, one reason users often notice that “body exhale” effect before bed. This is a meaningful dose, not label dressing. L-Tryptophan at 1,000mg is another standout because that is the threshold where the human evidence becomes relevant for sleep latency. Tryptophan is the dietary precursor to serotonin, which in turn feeds melatonin production. Alpha Lion supports that pathway intelligently with 12mg vitamin B6, a cofactor involved in neurotransmitter synthesis.

Melatonin is dosed at 2mg, which is a smart middle-ground dose: enough to reinforce the body’s sleep signal without pushing into the next-day fog that some higher-dose products create. Research on melatonin is strong for improving sleep quality, and in this formula it works best as part of the larger stack rather than as a standalone hammer. L-Theanine at 200mg is another clinically meaningful inclusion. Human trials at 200mg show reductions in stress markers and a calmer subjective state, which matters when the real issue is not fatigue but an overactive mind at bedtime.

GABA at 350mg adds another calming layer. Oral GABA research is less robust than melatonin or theanine, and blood-brain barrier questions remain, but human data does support a relaxation effect in some settings. That makes it a reasonable complementary ingredient here, especially when paired with theanine and glycine. KSM-66® Ashwagandha at 200mg is below the 600mg/day total used in the best stress and cortisol trials, but it is still a credible effective inclusion in a multi-ingredient nighttime formula. KSM-66 is one of the most respected branded ashwagandha forms because it uses a root-only extract standardized to 5% withanolides and has strong human data behind the ingredient line overall.

L-Glutamine at 2,000mg is more of a recovery-support inclusion than a direct sleep ingredient. It is not a primary reason to buy the formula, but it contributes to the product’s positioning as a nighttime muscle recovery supplement. Zinc at 27mg as zinc methionine is a serious dose, especially alongside magnesium and vitamin B6 in a ZMA-style framework. The magnesium bisglycinate chelate is well chosen from a form perspective because glycinate is one of the gentler, more sleep-friendly forms, though the elemental magnesium contribution here is modest at 40mg. Mucuna pruriens standardized to 40% L-Dopa at 175mg is an unusual inclusion in a sleep product; it likely aims to support mood and recovery-related neurotransmitter balance, but it is not a standard sleep staple and will matter more to some users than others. Chamomile at 75mg adds a traditional calming botanical touch, though this is not a heavily dosed herbal formula.

The system-level synergy is the real story. Tryptophan, B6, and melatonin support the serotonin-melatonin pathway. Theanine, glycine, GABA, chamomile, and magnesium support relaxation from multiple angles. KSM-66 adds stress modulation, while zinc and glutamine tilt the formula toward overnight recovery rather than simple sedation. AstraGin® at 50mg is included to support nutrient uptake, a useful touch in a powdered multi-ingredient formula.

Just as important, Alpha Lion uses full label transparency with no proprietary blends. In the sleep category, that matters. You can see exactly where this formula is strong: glycine, tryptophan, theanine, melatonin, and zinc. You can also see where some supporting ingredients are lighter. Day 1, expect easier mental decompression and a faster slide into sleep. Over 2-4 weeks, the bigger benefits are more consistent sleep timing, less bedtime restlessness, and better perceived recovery on waking.

Science & Clinical References 20 citations
Glycine and Sleep Thermoregulation4 studies

Glycine supports sleep through dual mechanisms: inhibitory neurotransmission and improved thermoregulatory signaling before bedtime. The thermoregulation angle matters because lowering core body temperature is one of the physiological cues associated with sleep initiation. At 3 grams, this formula reaches a clinically meaningful dose commonly used in human sleep studies. That makes glycine one of the most functionally relevant anchors in the blend.

Tryptophan as Upstream Sleep Chemistry2 studies

L-tryptophan is the essential amino acid precursor for serotonin synthesis, which in turn feeds endogenous melatonin production. Mechanistically, this gives tryptophan a foundational role in sleep-onset support rather than acting as a blunt sedative. A 1 gram dose sits at the threshold where sleep-latency evidence becomes practically relevant. It is especially useful in formulas aiming to support the body's natural sleep cascade.

Theanine, GABA, and Calm-State Signaling7 studies

Theanine is best understood as a calming neuromodulator that can reduce perceived mental overstimulation without acting like a classic sedative. GABA is included to reinforce the relaxation architecture, although oral GABA research remains more limited and variable than theanine or melatonin. Together, they create a multi-pathway relaxation effect aimed at reducing mental chatter and physical restlessness. This layered design is often better tolerated than relying on one heavy ingredient.

Melatonin Plus Adaptogen Support7 studies

Melatonin primarily functions as a chronobiotic, meaning it helps reinforce the timing signal that tells the body when to sleep. The 2 milligram dose here is moderate, which can support sleep onset without the overly heavy feel some users report from much larger doses. KSM-66 ashwagandha complements that by targeting stress physiology rather than circadian signaling directly. This combination makes the formula broader than a simple melatonin-only product.

Quick Answers

How much melatonin is in Alpha Lion Superhuman Sleep?

Each serving provides 2mg of melatonin. That is a moderate dose designed to reinforce the body’s sleep signal without going as heavy as the 5-10mg doses that often leave users groggy the next morning.

What are the main active ingredients in Superhuman Sleep?

The formula is built around 3,000mg L-glycine, 1,000mg L-tryptophan, 2,000mg L-glutamine, 350mg GABA, 200mg L-theanine, 200mg KSM-66® ashwagandha, 2mg melatonin, and 27mg zinc. That gives it a strong amino-acid and neurotransmitter-support profile rather than a simple melatonin-only design.

Is Alpha Lion Superhuman Sleep fully disclosed?

Yes. There are no proprietary blends in this formula, so every active ingredient and every dose is listed on the label. That is a major advantage in the sleep category, where many products hide behind vague “nighttime matrix” blends.

When should I take Superhuman Sleep?

Take 1 scoop about 20-30 minutes before bed. That timing gives theanine, glycine, tryptophan, GABA, and melatonin time to begin working as you transition into your wind-down routine.

Will this make me feel groggy in the morning?

Most users are less likely to experience next-day fog here than with very high-melatonin products because the formula uses a moderate 2mg dose. That said, melatonin sensitivity is individual, so new users may want to start with a half scoop to assess response.

How strong is the ashwagandha in this formula?

Superhuman Sleep uses 200mg KSM-66® Ashwagandha, a premium root-only extract standardized to 5% withanolides. The dose is below the 600mg/day used in the strongest standalone stress trials, but it is still a credible supporting amount inside a multi-ingredient nighttime formula.

Does this contain magnesium?

Yes, it includes magnesium bisglycinate chelate, a sleep-friendly form known for good tolerability. The elemental magnesium amount is 40mg, so the form is excellent but the dose is modest compared with standalone magnesium products.

Can I stack this with a separate magnesium supplement?

Yes, that is one of the smarter stack options for users who want a stronger mineral component. Since this formula only provides 40mg elemental magnesium, adding a standalone magnesium glycinate product can make sense without duplicating the core amino acid and melatonin blend.

Is Superhuman Sleep a good option for athletes?

Yes, especially for athletes who understand that sleep quality is a major performance variable. The formula supports both sleep initiation and overnight recovery with glycine, tryptophan, melatonin, zinc, glutamine, and KSM-66® ashwagandha.

Who should avoid this formula?

Anyone pregnant or nursing, under 18, or taking medications that affect serotonin or dopamine should avoid it unless cleared by a physician. The combination of melatonin, tryptophan, and Mucuna pruriens standardized to L-Dopa makes that caution especially important.
