Switch off faster and sleep deeper with Magnesium Bisglycinate, the form that gets deep into your nervous system.
This gives 100 mg of elemental Magnesium (Mg) per capsule, mainly from TRAACS-certified chelate bonded to the amino acid glycine.
It is a gentle, highly absorbable formula designed specifically for sleep, relaxation, and nervous system wellness.
The glycine carrier is a calming neurotransmitter, making this the preferred choice for anyone who takes Mg at night. What this means is the Magnesiumr elaxes you, and the glycine relaxes you.
It also includes pyridoxal 5-phosphate (active vitamin B6) to increase cellular uptake, plus the Magnifood botanical blend.
Vegan and filler-free.
High Absorption Magnesium Bisglycinate
The chelation process bonds Magnesium to two glycine molecules, protecting the nutrient from phytates, oxalates, and fibre that would otherwise block uptake.
- Schuette et al. (1994, Journal of Nutrition) demonstrated that amino acid chelates achieve significantly higher plasma levels than inorganic salts.
- The TRAACS certification means the chelate has been verified by Albion Minerals to be a true amino acid chelate rather than a simple blend.
Unlike oxide or citrate, this gentle type is far less likely to cause digestive discomfort or loose stools.
Magnesium Bisglycinate for Sleep & Calm
Mg works on the nervous system to help balance mental processes. It actually works and is useful to anyone struggling with difficulty sleepingor everyday tension.
The Abbasi et al. (2012, Journal of Research in Medical Sciences) trial in elderly participants found improved sleep onset, duration, and early morning waking.
It's not just magnesium that relaxes and helps with sleep. The glycine part adds to this profile: it acts as an inhibitory neurotransmitter and has been studied for its calming effect.
While Magnesium reduces tension, it paradoxically also helps reduce tiredness and fatigue, making it useful for those who wake unrefreshed.
Terranova Active Vitamin B6 (P5P)
This product includes pyridoxal 5-phosphate (P5P), the biologically active type of vitamin B6.
B6 calms you, and it also increases cellular Mg uptake (the amount of magnesium that gets inside a cell). Many cheaper formulas use pyridoxine hydrochloride, which the body must convert before use. This product cuts out that conversion step and allows this product to work relatively quickly.
Different types of magnesium
- Citrate is used for magnesium deficiency and digestion. It
works quickly and can help move the gut. Also helps muscles and stress a
little.
- Bisglycinate or glycinate is best for sleep, stress and
calming the nervous system. Also helps with muscle relaxation (great for post-workout muscle tightness) and bones.
- Malate is suited to energy production and muscle fatigue.
Also helps general magnesium levels, but not for sleep.
- Threonate is linked to brain function, focus and memory.
Also supports overall magnesium levels, but not for muscles or gut.
- Taurate is used for heart health and nervous system balance.
Also helps stress, but not for gut or sleep.
- Oxide is mainly used as a laxative and is poorly absorbed.
Limited benefit beyond gut use.
Because the different types of magnesium correct a deficiency that affects all will affect muscles, energy, stress, sleep, gut, etc. It is the salt they are paired up with that makes them particularly
How Magnesium Bisglycinate works
It works by binding magnesium to the amino acid glycine, which helps it absorb well and makes it gentler on the stomach.
Absorption and calming effect
The glycine helps carry magnesium into the body efficiently and also has its own calming effect on the nervous system.
Nervous system and sleep
It increases GABA activity, helping slow down brain activity and reduce that wired feeling. Glycine itself also causes relaxation, so this form is particularly useful for sleep.
Muscle relaxation
Like all magnesium, it regulates calcium in muscle cells, helping muscles relax and reducing tension and cramps. Calcium triggers contraction, magnesium allows relaxation.
Gentle on digestion
Unlike citrate, it doesn’t pull water into the bowel, so it
won’t have a laxative effect.
This type of magnesium is the best choice for calming, sleep and stress, with good absorption and no gut upset.
Take two to four capsules daily with food.
Each capsule has 100 mg of elemental Mg.
- At two capsules (200mg), you cover 53% of the EU NRV.
- At four (400mg), you exceed the NRV, which may suit those addressing a specific deficiency under practitioner guidance.
The EFSA supplemental upper limit is 250mg per day from supplements; doses above this are commonly used but should be discussed with your pharmacist or doctor.
When to Take Magnesium Bisglycinate for Sleep
For sleep or relaxation, the evening is ideal.
Take capsules with dinner or a light snack about an hour before bed. The glycine component has a naturally calming effect that works best when used in the evening.
For energy and fatigue reduction, a morning dose alongside breakfast works well.
Splitting the dose (one capsule morning, one evening) gives steady levels throughout the day. Taking food with it improves absorption.
How Long Does Magnesium to Work for Sleep?
- Many people notice improvements in sleep quality in one to two weeks of consistent nightly use.
- Muscle tension and cramps often ease in the first week.
- Tiredness and low energy may improve over two to four weeks as cellular stores are gradually replenished.
- Individual results vary depending on existing deficiencies, diet, and lifestyle.
- Give any Mg product at least four to six weeks before drawing conclusions.
Supplements to Take with Magnesium
- Vitamin B6 is already included as P5P.
- Vitamin D3 is the next most valuable companion: Mg is required to convert vitamin D into its active form, so taking one without the other limits effectiveness.
- Zinc pairs well for hormonal balance and immune function.
- Omega-3 fatty acids complement the neurological and mood-related benefits.
- If you also take Ca, space it an hour apart to reduce competition for absorption.
Chelated Magnesium Side Effects
The glycine-bonded version is one of the gentlest on the digestive system. Unlike oxide or citrate, it is far less likely to cause loose stools or stomach discomfort even at higher doses.
Magnesium Bisglycinate Drug Interactions
It can reduce absorption of certain antibiotics (tetracyclines and fluoroquinolones) and bisphosphonate medications for osteoporosis. Leave a two-hour gap. It is fine with penicillins.
FYI: Magnesium Bisglycinate
People prone to kidney disease should consult their doctor.
Pregnant and breastfeeding women should seek professional advice.
Store in a cool, dry place out of reach of children.
FAQs: Terranova Magnesium Bisglycinate
Can I Take Chelated Mg Every Day?
Yes. Mg is a daily essential that your body uses and excretes continuously. Consistent daily intake is more effective than occasional use. The chelated version is best for long-term daily use as it has less effect on the gastrointestinal tract.
Will This Gentle Version Cause Diarrhoea?
The glycine-bonded version is the least likely type to cause digestive issues. The osmotic laxative effect associated with oxide and citrate is largely absent because chelated versions are absorbed through amino acid pathways rather than drawing water into the bowel.
What Is the Difference Between Bisglycinate & Glycinate?
They are the same compound. The prefix 'bis' indicates two glycine molecules bonded to one Mg atom. Some brands say glycinate, others say bisglycinate. Both refer to the chelated version. Look for TRAACS certification to confirm a genuine chelate.
How Much Elemental Mg Is in Each Capsule?
100mg of elemental Mg per capsule. At two to four times daily, you receive 200-400mg, covering 53-107% of the EU NRV of 375mg.
Is This Product Suitable for Vegans?
Yes. Every ingredient is plant-based, including the vegetarian capsule shell. Free from wheat, soy, yeast, dairy, gelatine, and artificial additives.
