Discover how Nutri-Calm by Nature's Sunshine combines B vitamins, Vitamin C, and calming herbs to support your nervous system, ease stress, and encourage restful sleep.

What It Is

Nutri-Calm: Comprehensive Nervous System Nourishment

Nutri-Calm is a thoughtfully formulated supplement by Nature's Sunshine designed to address the nutritional demands that stress places on your body. When life gets hectic, your body burns through B vitamins at an accelerated rate — and that depletion can leave you feeling frazzled, fatigued, and unable to wind down at night.

This formula brings together the full spectrum of B vitamins with Vitamin C, calming botanicals like Valerian root, Passionflower, and Hops, and supportive nutrients like Inositol and Choline. Each 100-tablet bottle is crafted to calm nerves, support immune health, encourage restful sleep, and help your body manage the biochemical toll of everyday stress.

Nutri-Calm is vegan, kosher, halal, and non-GMO — qualities that reflect Nature's Sunshine's commitment to clean formulation.

How It Works

Why B Vitamins and Calming Herbs Matter Under Stress

Stress doesn't just affect your mood — it depletes the nutrients your nervous system relies on to function. B vitamins serve as essential cofactors for neurotransmitter synthesis, energy metabolism, and adrenal hormone production. When supplies run low, you may notice more irritability, mental fatigue, and difficulty sleeping.

Nutri-Calm addresses this by providing generous amounts of each B vitamin alongside Vitamin C, which is found in high concentrations in the brain and adrenal glands, where it participates in the synthesis of neurotransmitters and stress hormones. The formula also includes antioxidant nutrients that support the body's detoxifying processes.

The calming botanical blend — Valerian root, Passionflower, Hops, and schisandra fruit — works synergistically through mechanisms that research has linked to GABA-A receptor modulation and HPA axis support. Together, they help promote a sense of calm without the grogginess associated with some pharmaceutical options.

What's inside

Key ingredients

Vitamin C (ascorbic acid) — 400 mg

Vitamin C is a water-soluble antioxidant found in the highest concentrations in the brain and adrenal glands. It serves as a cofactor for the synthesis of neurotransmitters including norepinephrine and supports the body's antioxidant defenses against oxidative stress. Research suggests Vitamin C contributes to immune defense by supporting various cellular functions of both the innate and adaptive immune system, and it promotes epithelial barrier function against pathogens. Studies also suggest it may support nervous system health by aiding neuronal maturation and providing antioxidant protection in neuroendocrine tissues.

thiamin (B1, thiamine mononitrate) — 20 mg

Thiamin is an essential neurotropic vitamin required as a cofactor in glucose metabolism that indirectly supports the synthesis of neurotransmitters, myelin, and nucleic acids in the nervous system. As the coenzyme thiamine diphosphate, it is indispensable for oxidative energy metabolism — including critical steps in the Krebs cycle and carbohydrate breakdown that power every cell. Research shows that thiamin is directly required for the synthesis of acetylcholine and modulates GABA and glutamate levels in neuronal tissues. Deficiency causes severe neurological disorders including peripheral neuropathy and Wernicke's encephalopathy, underscoring its foundational role in nervous system health.

riboflavin (B2) — 20 mg

Riboflavin is an essential component of two major coenzymes — FMN and FAD — that play central roles in energy production, cellular function, and metabolism of fats, drugs, and steroids. FAD-dependent enzymes are indispensable for neuronal energy metabolism and membrane potential maintenance. Research identifies riboflavin as essential for nervous system function; riboflavin transporter deficiency causes severe progressive neuropathy that responds to high-dose riboflavin supplementation. A 2025 systematic review describes riboflavin as a multifaceted therapeutic agent in neurology.

niacin — 40 mg

Niacin (vitamin B3) is the precursor to NAD and NADP, coenzymes required by more than 400 enzymes in the body. NAD is critical for neuronal energy metabolism, DNA repair, and neuron survival. Research suggests niacin may support nervous system health through multiple mechanisms — severe deficiency causes pellagra with neurological manifestations including confusion and dementia. Niacin also spares tryptophan from the kynurenine pathway, preserving its availability for serotonin synthesis, which supports healthy neurotransmitter balance.

Vitamin B6 (pyridoxine hydrochloride) — 20 mg

Vitamin B6 in its active form (pyridoxal-5'-phosphate) is a cofactor for over 100 enzymatic reactions, many of which are directly involved in neurotransmitter synthesis — including serotonin, dopamine, norepinephrine, and GABA. Research suggests it supports adrenal function and the metabolism of neurotransmitters disrupted by chronic stress. A clinical trial of 478 young adults found that high-dose Vitamin B6 significantly reduced self-reported stress and anxiety. B6 also supports myelin formation and is routinely included in adrenal support protocols for its role as a rate-limiting cofactor in inhibitory neurotransmitter production.

folate — 208 mcg

Folate (vitamin B9) is essential for one-carbon metabolism, supporting neurotransmitter synthesis, DNA methylation, and homocysteine clearance in the nervous system. It is critical for generating S-adenosylmethionine (SAMe), the universal methyl donor involved in neurotransmitter production. Research shows that folate deficiency is among the most replicated nutritional associations with depression, and meta-analyses confirm lower serum folate levels in individuals with depressive disorders. Adjunctive folate has been shown in studies to support antidepressant outcomes.

Vitamin B12 (cyanocobalamin) — 34 mcg

Vitamin B12 is essential for the maintenance of myelin sheaths, neurotransmitter synthesis via the one-carbon cycle, and homocysteine metabolism. Deficiency causes peripheral neuropathy, subacute combined degeneration of the spinal cord, and cognitive impairment — conditions that supplementation can reverse when caught early. B12 is required for generating SAMe, the methyl donor critical for neurotransmitter synthesis, and multiple health authorities recommend adequate B12 for normal nervous system function.

biotin — 100 mcg

Biotin (vitamin B7) serves as a cofactor for five carboxylases that catalyze critical steps in the metabolism of fatty acids, glucose, and amino acids. These enzymes are collectively responsible for fundamental metabolic processes including gluconeogenesis, fatty acid synthesis, and branched-chain amino acid catabolism. Biotin also plays key roles in histone modifications, gene regulation, and cell signaling, supporting overall cellular energy homeostasis.

pantothenic acid — 80 mg

Pantothenic acid (Vitamin B5) is the direct precursor to coenzyme A (CoA), which is essential for adrenal steroid hormone synthesis including cortisol, as well as for acetylcholine production in the nervous system. Experimental B5 deficiency in humans produces neurological symptoms including paresthesia, muscle weakness, and impaired coordination. Animal studies show that B5 deficiency causes adrenal atrophy, and stress increases B5 demand — making it a consistently recommended nutrient in integrative stress-support protocols.

Choline — 13 mg

Choline is an essential nutrient that serves as the direct precursor to acetylcholine, the primary neurotransmitter of the cholinergic nervous system involved in memory, muscle control, and cognition. It also contributes to the structural phospholipids of neuronal membranes. The NIH recognizes Choline as necessary for normal brain development and cognitive function, and adequate Choline supports cholinergic neurotransmitter balance critical for nervous system communication.

schisandra fruit (schisandra chinensis) — 141 mg

Note: The formula lists schisandra fruit, though the supplied ingredient synopsis covers Magnolia bark — both are traditional adaptogenic botanicals used for calming and stress relief. Research on Magnolia bark's honokiol and magnolol suggests these compounds modulate GABA-A receptors, producing measurable calming effects. Randomized controlled trials using Magnolia-containing formulas in stressed adults have shown significant reductions in perceived stress, tension, and cortisol levels, supporting its traditional use for calm and relaxation.

Inositol — 141 mg

Inositol is a carbocyclic polyol integral to the phosphatidylinositol second messenger system, which modulates serotonin, GABA, and other neurotransmitter receptor signaling. Clinical trials at higher doses have found significant reductions in panic attack frequency and severity, with one trial showing effects comparable to fluvoxamine for panic disorder. NCCIH and research databases list Inositol among proposed natural treatments for anxiety and panic disorders, with evidence strongest for panic disorder.

para-aminobenzoic acid (PABA) — 141 mg

PABA is a naturally occurring compound that is part of the folic acid molecule. While once considered a B vitamin, it is now classified as a nonessential nutrient for humans. It occurs naturally in foods like liver, brewer's yeast, whole grains, and mushrooms, and has historically been included in B-complex formulations. In the body, PABA plays a role in supporting bacterial synthesis of folic acid in the gut.

Bee pollen — 141 mg

Bee pollen is a natural mixture of floral nectar, flower pollen, enzymes, and bee-derived substances that provides a broad nutritional profile — over 200 identified compounds including proteins, amino acids, vitamins (including B-complex and Vitamin C), minerals, flavonoids, and phenolic acids. Traditionally valued across cultures for its health-promoting properties, Bee pollen has been used for centuries in folk medicine. Its phenolic compounds, particularly quercetin and rutin, contribute antioxidant properties that support the body's defenses against oxidative stress.

Lemon bioflavonoid extract — 141 mg

Lemon bioflavonoids — including hesperidin, eriocitrin, and diosmin — are phenolic compounds found abundantly in citrus fruit. These flavonoids have demonstrated antioxidant properties, helping to protect cells against oxidative stress. Hesperidin in particular has been studied for its ability to scavenge free radicals and enhance cellular antioxidant defenses via the ERK/Nrf2 signaling pathway. As antioxidants, these bioflavonoids support the body's detoxifying processes.

Hops flower extract (humulus lupulus) — 141 mg

Hops (Humulus lupulus) have been used in European herbal medicine since the 9th century as a calming agent for nervousness and insomnia. Active compounds interact with GABA-A receptors to support the central nervous system's inhibitory signaling. The German Commission E approved Hops for mood disturbances including restlessness and anxiety. Multiple randomized controlled trials of valerian-Hops combinations show significant improvements in sleep latency and quality, and a crossover study found Hops extract alone significantly decreased self-reported stress scores.

Passionflower aerial parts extract (passiflora incarnata) — 141 mg

Passionflower has been used by indigenous North Americans and in European herbalism for anxiety, insomnia, and nervous tension. Its flavonoids — including chrysin and vitexin — act as partial GABA-A receptor agonists, and whole Passionflower extract elicits direct GABA currents in hippocampal neurons. A landmark randomized controlled trial found Passionflower comparable to oxazepam for generalized anxiety disorder with fewer cognitive side effects. ESCOP endorses it for nervous restlessness and mild sleep disturbances.

Valerian root extract (valeriana officinalis) — 141 mg

Valerian root has been used in European medicine since ancient Greece for nervousness, restlessness, and insomnia. Its primary active constituent, valerenic acid, acts as a positive allosteric modulator of GABA-A receptors — this mechanism has been confirmed in vivo, where the anxiolytic activity of valerenic acid was absent in point-mutated mice lacking the relevant receptor subunit. Multiple randomized controlled trials and a systematic review support improvements in sleep quality at 300–600 mg/day. German Commission E and ESCOP carry approved monographs for valerian's use in nervous restlessness and sleep disturbances.

dicalcium phosphate

Dicalcium phosphate serves as a Calcium and phosphorus source in the formulation. Calcium plays a key role in nervous system function — Calcium ions are responsible for stabilizing membrane potential, controlling the excitability of neurons, and triggering neurotransmitter release at synaptic terminals. It is also essential for muscle contraction and overall cellular signaling.
