The Science

Sleep isn’t something you force. It’s something your body allows when the right systems are supported.

Fika is a systems-based evening ritual, designed to support the biological processes that help the body unwind, the nervous system regulate, and the mind and muscles recover overnight.

Every ingredient in Fika is:

  • Clinically studied
  • Intentionally dosed
  • Selected for how it functions within the formula, not in isolation

This isn’t a sedative. It’s a coordinated reset.

How Fika Works

Sleep is the result of multiple systems working together. That’s why Fika supports six interconnected systems that shape how the body unwinds at night:
Calm Gut Mind
Muscle Nervous System Sleep

Some ingredients support more than one system. Why? Because the body doesn’t work in silos. Each ingredient is grouped under the system it supports the most, so you can see how it all works together for a full-body reset. 

Calm

Sensoril® Ashwagandha

Helps regulate stress so the body can begin to unwind. Ashwagandha has been clinically studied for its ability to support cortisol regulation and stress resilience. We selected the Sensoril® extract for its standardized composition and consistent performance in evening use. Standardization matters in multi-ingredient formulas, where variability can affect night-to-night consistency.

L-Theanine

Supports calm brain activity without sedation. L-theanine supports alpha brain wave activity and neurotransmitter balance. We included it to help the nervous system transition out of stimulation while preserving natural sleep signaling. Its non-sedating profile allows it to pair cleanly with other calming compounds without dulling sleep architecture.

Honokiol (Magnolia Bark Extract)

Supports relaxation pathways involved in stress regulation. Honokiol has been studied for its interaction with GABA-related pathways. We selected a standardized magnolia bark extract to provide reliable, non-sedating support as part of the evening wind-down process. This allows calming support without relying on knock-out mechanisms.

Nervous System

Saffron Extract

Supports neurotransmitter balance involved in nervous system regulation. Saffron has been clinically studied for its role in emotional and neurological regulation. We included it to support serotonin-related pathways that influence nervous system tone in the evening. This complements calming ingredients by supporting neurotransmitter balance upstream.

Glutathione

Supports cellular protection within the nervous system. Glutathione is the body’s primary antioxidant and plays a key role in protecting neural tissue from oxidative stress. We included it to support nervous system resilience during the body’s most active overnight recovery window. Cellular protection becomes especially relevant when multiple signaling pathways are being modulated simultaneously.

Mind

Magnesium L

Supports brain-level magnesium availability. L-threonate is uniquely studied for its ability to cross the blood–brain barrier. We selected this form to support central nervous system signaling and cognitive regulation in the evening. In a multi-ingredient formula, this allows magnesium to support the brain directly rather than competing with peripheral demands.

Myo-Inositol

Supports cellular signaling involved in mental regulation. Myo-inositol plays a role in neurotransmitter pathways and intracellular communication. We included it to support stable signaling as the brain transitions into rest. This supports mental regulation alongside ingredients that focus on stress and sleep depth.

Vitamin B6 (Pyridoxal-5-Phosphate)

Supports neurotransmitter synthesis pathways. Vitamin B6 acts as a critical cofactor in the synthesis of neurotransmitters such as serotonin and GABA. We selected the active P-5-P form so the body can use it directly, without additional conversion steps. This ensures efficient neurotransmitter support within a complex formula.

Sleep

Glycine

Supports natural sleep architecture. Glycine has been studied for its role in thermoregulation and sleep quality. We included it at a gram-level dose consistent with clinical research. Most sleep formulas include glycine far below the levels studied for sleep architecture.

Apigenin

Supports sleep-related GABA receptor activity. Apigenin is a bioactive flavonoid that interacts with GABA receptors involved in sleep regulation. We selected it to support sleep depth without relying on melatonin or sedative compounds. This allows sleep signaling to remain aligned with the body’s natural rhythms.

Zylaria®

Supports sleep continuity and nighttime regulation. Zylaria is a functional mushroom studied for its calming and sleep-supportive properties. We included it to support consistent nighttime regulation without disrupting normal sleep cycles. Its role complements ingredients that focus on calming and architecture rather than sedation.

Muscle

Magnesium Glycinate

Supports brain-level magnesium availability. L-threonate is uniquely studied for its ability to cross the blood–brain barrier. We selected this form to support central nervous system signaling and cognitive regulation in the evening. In a multi-ingredient formula, this allows magnesium to support the brain directly rather than competing with peripheral demands.

L-Ornithine HCl

Supports overnight recovery processes.
L-ornithine assists with ammonia clearance during rest. We included it to support metabolic recovery following daily physical or mental exertion. This adds a recovery dimension most sleep formulas overlook.

L-Taurine

Supports neuromuscular signaling balance.Taurine plays a role in regulating excitatory activity in muscle tissue. We included it to support physical relaxation during sleep.Its signaling role complements magnesium’s structural support.

Gut

Absorption & Bioavailability

Most supplements fail for one simple reason:
 the ingredients never make it into circulation.


Fika was designed with absorption in mind.

Sunflower Lecithin

Supports liposomal-style nutrient delivery. Sunflower lecithin provides phospholipids that help form liposomal and liposome-like structures, improving transport of nutrients across the intestinal barrier. We included it to enhance bioavailability throughout the entire formula. Phospholipids act as delivery vehicles, not just fillers.

AstraGin®

Clinically shown to increase nutrient absorption. AstraGin® has been shown in human and cellular studies to increase amino acid absorption by up to 50%, while also enhancing uptake of minerals and plant compounds. We selected AstraGin® to help ensure ingredients are absorbed efficiently. This matters most in formulas where multiple amino acids and minerals are present simultaneously.

The Absorption Advantage

By pairing phospholipid-supported delivery with clinically validated absorption enhancement, Fika addresses a layer of formulation most sleep products ignore.

This isn’t about adding more ingredients.
 It’s about making the ingredients you take actually matter.
