  • An adult body contains approximately 25g of magnesium — 50–60% stored in bones, the remainder in muscles and soft tissue (NIH ODS)
  • Magnesium participates in more than 300 enzymatic reactions, including protein synthesis, muscle and nerve function
  • People who exercise intensely or sleep poorly tend to lose more magnesium through sweat, requiring 10–20% higher intake (PMC 2024)
  • Magnesium Citrate offers superior bioavailability compared to magnesium oxide, ideal for efficient replenishment

About Swisse UB Magnesium 150mg

What is Swisse Magnesium?

Swisse UB Magnesium 150mg is a dietary supplement providing magnesium as Magnesium Citrate — a highly bioavailable form efficiently absorbed by the body.

Each tablet contains Magnesium Citrate 976.47mg, delivering 150mg elemental magnesium. Magnesium is an essential mineral involved in over 300 enzymatic reactions — supporting muscle and nerve function, protein synthesis, DNA replication, and the structural maintenance of bones and teeth.

Swisse is an Australian wellness brand manufactured to international standards, officially imported by H&H (Thailand). Each tablet provides a practical daily dose of Swisse Magnesium to support muscle and nervous system health.

What does Swisse Magnesium help with?

Per approved label claims, Swisse Magnesium contributes to:

  • Bones & Teeth — Magnesium is a structural component of bones and teeth
  • Muscle & Nervous System — Contributes to the normal function of the muscle and nervous system

Scientific research also identifies magnesium's involvement in:

  • Reducing post-exercise muscle fatigue and soreness
  • Supporting nervous system function and sleep quality
  • Regulating blood sugar levels and blood pressure
  • Maintaining bone mineral density

Note: Research findings reflect general scientific information about magnesium and do not constitute disease treatment claims.

How to take Swisse Magnesium / Recommended dose

How to take Swisse Magnesium 150mg (general supplement guidance):

  • Dose: 1 tablet per day (150mg elemental magnesium)
  • Timing: Take with or after food to minimise stomach discomfort. For sleep and relaxation support, take 30–60 minutes before bedtime
  • Water: Take with a full glass of water (200ml) to aid absorption

Best time to take Swisse Magnesium depends on your goal:

  • Morning — ideal for those who train in the morning or want all-day muscle support
  • Evening/bedtime — ideal for muscle relaxation and recovery during sleep

⚠️ Consult a pharmacist or doctor for personalised guidance, especially if you have kidney disease or take regular medication.

Side effects of Swisse Magnesium

Swisse Magnesium and magnesium supplements generally have an excellent safety profile at recommended doses. Possible side effects include:

Common side effects:

  • Nausea, upset stomach, or bloating — usually occurs when taken on an empty stomach; resolved by taking with food
  • Loose stools or mild diarrhoea — occasionally seen with magnesium citrate at higher doses (150mg/day is generally well tolerated)
  • Mild abdominal discomfort

Signs to stop and seek medical advice:

  • Allergic reaction: rash, swelling, difficulty breathing
  • Unusual muscle weakness, slow or irregular heartbeat, low blood pressure
  • These may indicate magnesium excess (rare in individuals with normal kidney function)

People with kidney disease should not take magnesium supplements without medical guidance, as kidneys are responsible for excreting excess magnesium.

Contraindications / Precautions

Contraindications for Swisse Magnesium:

  • Allergy to any ingredient in the product
  • Severe renal impairment — do not use without medical supervision
  • Pre-existing hypermagnesemia (elevated blood magnesium)

Precautions:

  • Drug interactions:
    • Quinolone antibiotics (e.g., Ciprofloxacin) and Tetracyclines — space at least 2 hours apart, as magnesium reduces antibiotic absorption
    • Bisphosphonates (bone medications) — space at least 2 hours apart
    • Potassium-sparing diuretics — may elevate magnesium levels further
    • High-dose calcium or zinc supplements — take separately to avoid absorption competition
  • Pregnant or breastfeeding women — consult a doctor before use
  • Children under 15 years — not recommended without medical guidance
  • Total supplemental magnesium from all sources should not exceed 350mg/day (NIH UL) for safety

Can I take Swisse Magnesium with other supplements?

Generally, Swisse Magnesium can be taken alongside most vitamins and supplements, but a few combinations require care:

  • Vitamin D3 — Compatible and potentially synergistic; Vitamin D helps the body absorb calcium and magnesium more effectively
  • Calcium — Take 1–2 hours apart; calcium and magnesium share the same absorption pathway, so taking large doses simultaneously may reduce efficiency
  • Zinc — Space doses if taking high-dose zinc to avoid absorption competition
  • B vitamins, Vitamin C — No interaction; can be taken together
  • Omega-3 — No interaction; compatible

For prescription medications — especially antibiotics, antacids, bone medications, and diuretics — refer to the Contraindications tab and always consult a pharmacist or doctor.

How quickly does Swisse Magnesium work?

How quickly Swisse Magnesium produces effects depends on your goal and existing magnesium levels:

  • Absorption: Magnesium Citrate tablets begin absorbing within 1–2 hours after ingestion (Drugs.com)
  • Blood magnesium levels: Begin rising within 1–2 hours post-dose, but fully replenishing magnesium in muscles and bones requires consistent daily use over several weeks
  • Muscle fatigue reduction: Some individuals notice improvement within 1–2 weeks of consistent supplementation
  • Long-term bone support: Requires months to years of regular supplementation to see measurable effects on bone density

Those with existing magnesium deficiency typically experience faster improvement in sleep quality and muscle relaxation. Consistency is more important than high single doses.

Frequently Asked Questions

Magnesium contributes to normal muscle and nervous system function, supports bones and teeth, and participates in over 300 enzymatic reactions including protein synthesis, energy production, and blood sugar regulation. For regular exercisers, magnesium can help reduce post-exercise muscle fatigue.

Swisse Magnesium can be taken any time of day, but it is best taken with food or after a meal to minimise stomach discomfort. For those seeking sleep or nighttime muscle support, taking it 30–60 minutes before bed may be most beneficial. For daytime muscle support, morning with breakfast works well.

Space magnesium at least 2 hours from quinolone and tetracycline antibiotics (magnesium binds these and reduces absorption), bisphosphonates, and certain diuretics. Take high-dose calcium supplements 1–2 hours separately to avoid absorption competition.

Both forms are highly bioavailable. Glycinate is gentler on the digestive system and may add calming effects from glycine. Magnesium citrate (Swisse Magnesium) is excellent value with proven bioavailability — ideal for everyday muscle and bone support.

At 150mg/day, side effects are rare. Taking on an empty stomach may cause mild nausea. Exceeding 350mg/day from supplements may cause diarrhoea, low blood pressure, or irregular heartbeat — especially with impaired kidney function. Follow recommended dose and consult a pharmacist if unsure.

Swisse Magnesium supports normal muscle function, reduces post-exercise fatigue, and replenishes electrolytes. Active individuals require 10–20% more magnesium than sedentary people. Taking it in the evening or post-workout may aid muscle recovery.

Swisse Magnesium uses Magnesium Citrate — better absorbed than magnesium oxide in cheaper products. Swisse is an internationally certified Australian brand, officially imported by H&H (Thailand), making it a reliable choice for daily supplementation.

Magnesium supports nervous system function including relaxation processes. Low magnesium may correlate with poorer sleep quality. Swisse Magnesium is a dietary supplement, not a sleep aid — sleep benefits are most likely in those with existing deficiency.

Yes — Swisse Magnesium is designed for daily use, one tablet per day at 150mg, which is well within the safe range per NIH guidelines (the supplemental upper intake limit is 350mg/day). Consistent daily use is more effective than occasional high doses for maintaining balanced magnesium levels in the body.
