🧠 Magnesium, GABA and Psychological Function

Magnesium plays a critical role in GABA (gamma-aminobutyric acid) neurotransmitter activity — GABA is the primary inhibitory neurotransmitter in the central nervous system, responsible for reducing neuronal excitability. Magnesium also acts as a natural antagonist of NMDA (N-methyl-D-aspartate) receptors — blocking the overactivation of excitatory glutamate pathways. This is the physiological basis for the authorised claim that magnesium contributes to normal psychological function. A 2017 systematic review (Boyle et al., Nutrients, PubMed 28445426) examined magnesium supplementation and its effects on subjective markers of psychological wellbeing, finding associations in populations with low magnesium intake.

⚡ Magnesium and the HPA Stress Axis

The hypothalamic-pituitary-adrenal (HPA) axis regulates the body's response to perceived stress — controlling the release of cortisol and other stress hormones. Magnesium has been documented to modulate HPA axis activity. Reciprocally, periods of high psychological demand increase urinary magnesium excretion — creating a cycle where magnesium insufficiency can amplify the physiological stress response, and physiological stress can deplete magnesium further. This is the context in which the authorised claim for magnesium contributing to normal nervous system function is particularly relevant.

💪 Magnesium and Muscle Relaxation

Muscle contraction requires calcium to enter the muscle cell — and muscle relaxation requires calcium to be actively pumped back out. Magnesium regulates this process: it competes with calcium at voltage-dependent calcium channels and activates calcium pumps (SERCA) that restore the resting state of muscle fibres. Without adequate magnesium, the relaxation phase of the contraction-relaxation cycle is impaired — which is the physiological basis for the authorised claim that magnesium contributes to normal muscle function. This mechanism applies to skeletal muscle, smooth muscle and cardiac muscle. Educational background only — food supplement, not a medicine.

💊 Glycine — The Second Active Component

In Magnesium Bisglycinate, glycine is not merely a carrier molecule. Glycine is an inhibitory neurotransmitter in its own right — acting at glycine receptors in the spinal cord and brainstem, where it reduces neuronal firing. A 2012 human study (Yamadera et al.) found glycine ingestion significantly improved subjective sleep quality in volunteers. A 2015 study found glycine supplementation reduced subjective daytime fatigue following sleep restriction. These are academic findings regarding glycine's independent properties — not additional health claims for the magnesium supplement. In Magnesium Bisglycinate, the glycine carrier delivers both the chelation benefit (improved magnesium absorption) and its own documented amino acid activity.

📊 Why 60% of UK Adults Are Below the Magnesium RNI

The NDNS 2019–2023 data shows approximately 60% of UK adults fall below the RNI for magnesium — 300mg/day for men and 270mg/day for women. Contributing factors include: declining soil magnesium levels in UK agricultural land (reducing content in vegetables even when consumed regularly); high consumption of ultra-processed foods which are low in magnesium; coffee and alcohol consumption which increases urinary magnesium excretion; and chronic stress — which itself accelerates magnesium depletion through increased urinary and faecal excretion. This creates a particular relevance for magnesium's authorised claim for normal psychological function and nervous system function — those under high psychological demand may have increased magnesium needs.

What is CHILLME'S Magnesium Glycinate 300mg?

CHILLME'S Magnesium Glycinate 300mg Tablets (by Charge Products — Big Idea Services Ltd, Co. No. 11645389) contain 300mg Magnesium Glycinate (Bisglycinate) per tablet. Chelated form for superior absorption. 10 authorised EU/UK health claims including normal psychological function, normal nervous system function and normal muscle function. In-house manufactured at our 5 Star FSA Essex facility. Food supplement — not a medicine.

Does magnesium contribute to normal psychological function?

Yes — "Magnesium contributes to normal psychological function" is an authorised EU/UK health claim. Magnesium plays a documented role in GABA inhibitory neurotransmission and acts as a natural NMDA receptor antagonist — blocking overactivation of excitatory glutamate pathways. A 2017 systematic review (Boyle et al., PubMed 28445426) found associations between magnesium supplementation and subjective psychological wellbeing markers. Educational background only — food supplement, not a medicine.

How does magnesium support the nervous system?

Magnesium contributes to normal nervous system function — an authorised EU/UK health claim. It acts as a natural antagonist of NMDA excitatory receptors, supports GABA inhibitory pathways, and has been documented to modulate the HPA stress-response axis. Periods of high psychological demand increase urinary magnesium excretion — making adequate intake particularly relevant for nervous system support. Educational background only — food supplement, not a medicine.

How does magnesium support muscle function?

Magnesium contributes to normal muscle function — an authorised EU/UK health claim. Muscle relaxation requires calcium to be actively pumped back out of the muscle cell after contraction. Magnesium activates the calcium pumps (SERCA) responsible for this process. Without adequate magnesium, the relaxation phase of the muscle contraction-relaxation cycle is impaired. This applies to skeletal muscle, smooth muscle and cardiac muscle. Educational background only — food supplement, not a medicine.

Why is Magnesium Bisglycinate better than Magnesium Oxide?

Magnesium Oxide has approximately 4% bioavailability — most passes through unabsorbed and causes a laxative effect at higher doses. Magnesium Bisglycinate (Glycinate) is chelated to glycine, using active amino acid transport in the gut wall to significantly improve absorption efficiency. No laxative effect at standard doses. Widely considered the preferred form for daily supplementation. Educational background only — food supplement, not a medicine.

What are all 10 authorised health claims for magnesium?

Normal muscle function · normal nervous system function · normal psychological function · reduction of tiredness and fatigue · normal energy-yielding metabolism · maintenance of normal bones · maintenance of normal teeth · normal protein synthesis · normal cell division · electrolyte balance. All authorised under EU Regulation 1924/2006 retained in UK law. These are the only claims made for this product. Food supplement — not a medicine.

When is the best time to take CHILLME'S Magnesium Glycinate?

Follow the directions on the product label. Magnesium Glycinate can be taken at any time of day. Many people take it in the evening as part of their routine. It can be taken with or without food. Consult your GP before use if taking any prescription medication. Food supplement — not a medicine.

How does CHILLME'S differ from other Charge Products magnesium tablets?

CHILLME'S Magnesium Glycinate 300mg Tablets are positioned around the psychological function, nervous system and muscle function authorised claims — the mental wellness and muscle relaxation angle. Sleep Bombs 300mg Magnesium Glycinate Tablets are positioned around the evening routine and muscle recovery angle. Both contain the same Magnesium Bisglycinate active ingredient. For higher strength, the Magnesium Glycinate 650mg Capsules deliver more than double the magnesium per serving in a no-filler capsule format. Food supplement — not a medicine.
