Overview: Product Description
MgO 240 mg Magnesium is a high‑potency mineral supplement designed to deliver a full 240 mg of elemental magnesium per capsule, offering targeted support for energy production, muscle relaxation, nerve‑function and cardiovascular health. One capsule provides 240 mg of magnesium (of which a minimum of ~60 mg is absorbed) – already more than many standard formulations. In a time when magnesium intake from food and water sources is often insufficient, this high‑dose formula fills a crucial gap. With consistent use, it supports improved muscle performance, reduced cramps, calmer nerves, healthier blood‑pressure regulation, better sleep and mood stability — all from a trusted South African brand.
Why MgO?
Magnesium is one of the “quiet” minerals often overlooked, yet it is essential in 300+ metabolic reactions, including energy generation, muscle contraction, nerve signalling, bone structure and cardiovascular regulation. Modern lifestyle factors – e.g., refined diets, low‑mineral water, heavy sweating, chronic stress or ageing – increase magnesium loss or need. Many adults fail to achieve the higher intakes our ancestors enjoyed (≈ 600 mg/day) and that supplementation is often the only practical option. The need: many users still feel fatigue, muscle tightness, cramps, poor sleep, mood swings or elevated blood pressure despite “healthy” diets — because underlying magnesium status remains low. MgO 240 mg is formulated to meet that need with a straightforward high‑dose daily capsule.

Benefits
- Delivers 240 mg elemental magnesium per capsule – a high strength dose compared to many magnesium supplements.
- Supports muscle function and relaxation — helps reduce cramps, tension, muscle fatigue, especially after exercise or high load.
- Contributes to nerve and nervous‑system health — important for nerve transmission, calmness, better sleep and mood.
- Promotes cardiovascular & blood pressure support — magnesium is key for heart‑muscle performance, vascular tone and general heart health.
- Supports energy metabolism — since magnesium is required for ATP production and over 300 enzymatic reactions, better magnesium means better energy, less fatigue.
More Advantages
- Highly affordable and value‑packed given the high dose (240 mg) from a local South African brand.
- Easy single‑capsule dosing: simple regimen supports adherence.
- Broad applicability: suitable for men and women of varying ages, active individuals, stressed professionals and those seeking general wellness.
- Backed by educational content: Doc Frank’s commentary emphasises the importance of magnesium and why many diets fall short.
- Long shelf life when stored well; the product is clearly labelled with potency and batch details.
Supplement Profile
Active Ingredients
- Magnesium (as Magnesium Oxide, MgO) – 240 mg elemental magnesium per capsule: This high dose supports multiple systems. Although magnesium oxide has sometimes been criticised for poor absorption, when formulated correctly (capsule form, good dissolution) it still provides meaningful absorption.
Magnesium’s physiological roles:
- Acts as co‑factor in >300 enzymatic reactions (energy production, muscle/nerve transmission, bone mineralisation)
- Supports muscle relaxation and prevents excessive contraction/cramps
- Helps nerve‑cell signalling and GABAergic (calming) neurotransmission
- Helps regulate vascular tone, blood pressure and cardiovascular health
- Supports bone health alongside calcium, boron and vitamin D

Precautions
- Pregnancy & Breast‑feeding: If pregnant or breastfeeding, consult a healthcare provider before use. While magnesium is generally safe, high doses may lead to digestive upset or other effects.
- Age Restrictions: Intended for adult use; for children, adolescents or those with special conditions consult a healthcare professional.
- Contraindications / Interactions: Magnesium interacts with certain medications (e.g., antibiotics such as tetracyclines/quinolones, bisphosphonates, magnesium may affect digestion of other minerals, diuretics may increase magnesium loss). Also kidney disease, heart‑block, or disorders of magnesium handling warrant professional supervision. The form (MgO) can have a laxative effect at high doses.
- Side Effects: Generally well tolerated at normal doses, but high intake of magnesium oxide may cause diarrhoea, stomach cramps or loose stools due to the poorly absorbed form.
Storage Instructions
- Store in a cool, dry place away from direct sunlight.
- Keep bottle tightly closed when not in use.
- Keep out of reach of children.
- Use by expiry date printed on label.
- Discard if seal is broken.
Directions
- Take 1 capsule daily, ideally with food to enhance absorption and minimise digestive upset.
- For higher demand (e.g., athletes, persons under heavy stress, or on magnesium‑wasting medications) you may take 2 capsules daily (morning + early evening) or as advised by your health practitioner.
- Do not exceed recommended dosage unless under professional supervision.
- If you experience loose stools, reduce dose or take with a larger meal.
- Ensure adequate hydration and overall mineral balance (e.g., calcium, vitamin D) for optimal effect.
- Magnesium (as MgO) supplies the body with elemental magnesium which supports hundreds of enzymatic reactions across energy‑metabolism, muscle/nerve conduction, bone health and cardiovascular function.
- Although magnesium oxide traditionally has lower solubility and absorption compared to some organic magnesium salts, Integrow points out that when formulated in capsule form and delivered at 240 mg dose, meaningful absorption (60 mg or more) is achieved.
- As magnesium supports muscle relaxation, nerve cell stability (via GABA pathways) and vascular smooth‑muscle tone, consistent supplementation helps reduce muscle cramps, nervous tension, stress‑loads, and supports stable heart rhythm and blood pressure.
- The high dose (240 mg) ensures you receive a substantial amount of elemental magnesium, helping to replenish deficits many modern adults have due to diet, lifestyle or mineral‑poor water sources.
- Adults experiencing muscle cramps, tension or fatigue — especially athletes, gym‑goers, or those with heavy training or sweating.
- Professionals or high‑stress individuals with nerve tension, poor sleep or mood instability, who may benefit from improved magnesium status for calming effects.
- Older adults or those with dietary insufficiency who suspect magnesium deficiency, given modern diets and mineral‑poor water.
- Individuals with elevated blood pressure, cardiovascular risk or heart‑muscle strain, as magnesium supports vascular tone and heart function.
- Anyone seeking a straight‑forward, high‑dose magnesium supplement from a trusted local brand – who prefers simplicity and potency in one capsule.
- High‑potency dose: 240 mg elemental magnesium per capsule is above many standard magnesium supplements in South Africa.
- Single‑capsule simplicity: One capsule daily makes it easy to integrate into daily routine — no complicated splits or large pills.
- Local South African brand: Integrow Health brings the product to local market with local support, reliability and accountability.
- Value pricing: Integrow offers 60‑, 120‑, and 500‑capsule packs, enabling both short‑term use and cost‑effective bulk.
- Focused on mineral wellness: Rather than being a broad “mega‑multivitamin”, this formula zeroes in on magnesium — one nutrient many people miss.
- Backed by science: While MgO may have lower absorption than some forms, the high‑dose and proper formulation mean the product still delivers significant benefit.
Science
-
The US National Institutes of Health’s Office of Dietary Supplements notes that absorption of magnesium varies widely depending on the form: magnesium oxide and magnesium sulfate are absorbed less completely than other forms (e.g., aspartate, citrate, chloride). Office of Dietary Supplements
-
A 2011 study comparing magnesium oxide formulations found urinary magnesium excretion (a proxy for absorption) rose by 40% for an effervescent MgO tablet but only 20% for MgO capsules — underscoring the challenges of MgO absorption. PubMed
-
A 2019 study of 15 magnesium supplements found wide variation in dissolution and absorption — emphasizing that form and formulation matter. PMC
