The molecule your body uses to store and transfer energy at the cellular level. Every time your muscles contract, your nerves fire, or your cells repair themselves, ATP is what powers the process. Magnesium is required for ATP to be biologically active — without sufficient magnesium, your cells cannot use the energy they produce. This is one reason magnesium deficiency shows up as fatigue and slow recovery, not just muscle tension.

A naturally occurring aromatic compound found in black pepper, cloves, cinnamon, copaiba, rosemary, and other botanicals. One of the only non-cannabinoid plant compounds known to directly activate CB2 receptors in the body's endocannabinoid system. Reduces inflammatory signaling and pain receptor intensity without psychoactive effects. Found in highest concentrations in copaiba oleoresin — up to 50–80% of its total composition.

How much of a substance your body can actually absorb and use after you take it. A supplement can contain a large dose of an ingredient but have low bioavailability — meaning most of it passes through without being absorbed. Magnesium oxide, for example, is common in cheap supplements but has poor bioavailability compared to forms like glycinate or malate. The form matters as much as the amount.

A selective filtering system that controls what passes from the bloodstream into the brain. Most forms of magnesium do not cross it easily — magnesium threonate is the exception, which is why it's the form studied specifically for cognitive and neurological applications.

One of two primary receptor types in the body's endocannabinoid system. Found predominantly in immune tissue — the spleen, tonsils, gut lining, and peripheral nervous system — CB2 receptors regulate the body's inflammatory response and peripheral pain signaling. Unlike CB1 receptors (found in the brain and central nervous system), CB2 receptor activation has no psychoactive effects. Beta-caryophyllene binds selectively to CB2 receptors — which is why copaiba can address inflammation and pain through the endocannabinoid system without the associations of cannabis.

A natural oleoresin extracted from the Copaifera tree, native to the Amazon rainforest. One of the richest known plant sources of beta-caryophyllene — up to 80% of its composition. Used for centuries by indigenous Amazonian communities for anti-inflammatory and wound-healing properties. Copaiba is often compared to CBD because both interact with the endocannabinoid system, but copaiba works specifically through CB2 receptors without cannabinoids or psychoactive associations.

The actual amount of magnesium in a supplement, separate from the compound it's bound to. A capsule of magnesium glycinate might weigh 500mg, but the elemental magnesium content — the amount your body can use — is a fraction of that. Always check the elemental magnesium figure on a supplement label, not just the total weight per serving.

A biological regulatory network found in every human body — discovered in the early 1990s while researchers were studying cannabis. The name is historical, not botanical: the system exists independently of cannabis. The ECS consists of receptors (CB1 and CB2), naturally produced signaling compounds called endocannabinoids (including anandamide and 2-AG), and enzymes that break them down after use. Its primary function is balance — regulating pain perception, inflammation, sleep, stress response, and mood.

An essential mineral involved in over 300 biochemical processes — including muscle contraction and relaxation, nerve signaling, pain regulation, energy production, and inflammation management. Chronically under-consumed; estimates suggest up to 50% of US adults are deficient. Available in multiple forms with different absorption rates and applications: glycinate and malate for oral supplementation; chloride for topical oils and sprays; sulfate (Epsom salt) for bath soaks.

The form of magnesium used in topical oils and sprays. Highly soluble and absorbs efficiently through skin, bypassing the digestive system entirely — delivering magnesium directly to muscle tissue. This is why magnesium chloride is the standard for topical applications and why athletes and chronic pain sufferers use magnesium oils and sprays for localized muscle tension and recovery.

Magnesium bound to sulfate — commonly known as Epsom salt. Absorbs transdermally during a warm bath soak. The warmth increases circulation while magnesium enters through the skin. Best used for whole-body muscle relaxation and recovery rather than targeted localized pain. The sulfate component also supports detoxification pathways. This is the form found in the Hello Wellness Bath Soaks.

Receptors in the nervous system involved in pain signaling and nerve excitability. Magnesium naturally blocks these receptors when levels are sufficient — keeping pain signals proportionate to what's actually happening. When magnesium is low, NMDA receptors become overactive, amplifying pain signals and making the nervous system more reactive overall. This is why chronic magnesium deficiency is linked to pain that feels more intense than the underlying cause warrants.

The outermost layer of the skin — the primary barrier between the body and the outside world. In transdermal absorption, this is the layer a substance must pass through to reach deeper tissue. Its thickness and composition vary by body part, which is one reason absorption rates differ depending on where a topical product is applied. Thinner skin (inner wrists, inner arms, behind the knees) absorbs more readily than thicker skin (palms, soles of feet).

Describes anything delivered through the skin rather than taken orally. Topical magnesium — oils, sprays, bath soaks — works transdermally, bypassing the digestive system and delivering magnesium directly to local tissue. The degree to which magnesium absorbs transdermally is still debated in the research literature; what's consistent is that topical application produces measurable effects on muscle tension and recovery, even if the precise mechanism isn't fully settled.
