About Blackmores Bio Magnesium Advance + D3
What is Blackmores Bio Magnesium Advance + D3?
Blackmores Bio Magnesium Advance + D3 is a magnesium dietary supplement that combines Cholecalciferol (Vitamin D3) in a single formula.
How Magnesium works: Magnesium is an essential macromineral that plays a key role in nerve signal transmission, muscle contraction and relaxation, protein synthesis, and blood sugar regulation.
How Vitamin D3 (Cholecalciferol) works: Vitamin D3 stimulates calcium and phosphorus absorption in the small intestine, and helps regulate blood calcium levels — essential for bone strength and muscle function.
This combination is ideal for those who want to support muscle health, nervous system function, and bone health in a single supplement.
What is Blackmores Magnesium used for?
Blackmores Bio Magnesium Advance + D3 supports the following according to its label claims:
Muscles: Magnesium supports normal muscle function, including muscle cramps and tension
Nervous system: Magnesium supports normal nerve signal transmission
Bones: Vitamin D3 (Cholecalciferol) helps with calcium and phosphorus absorption, contributing to bone strength
Energy: Magnesium participates in cellular energy production (ATP synthesis)
Suitable for active individuals, regular exercisers, or those looking to maintain long-term bone and muscle health.
How to take Blackmores Magnesium / Recommended dosage
How to take Blackmores Magnesium per label instructions:
Adults: Take 1 tablet daily with or after food

Side effects of Blackmores Magnesium
Blackmores Bio Magnesium Advance + D3 is generally well-tolerated at recommended doses. Some people may experience:
Gastrointestinal: Nausea, stomach discomfort, or loose stools at higher doses — can be minimised by taking with food
Excess Vitamin D3: If combining D3 from multiple sources, there is a risk of hypervitaminosis D — symptoms include nausea, fatigue, headache
If you experience any unusual symptoms, stop use and consult a doctor or pharmacist.
Contraindications / Precautions
Precautions when taking Blackmores Magnesium:
Those with kidney disease should consult a doctor first, as kidneys play a key role in filtering excess magnesium

Can Blackmores Magnesium be taken with other medications or supplements?
Key interactions to be aware of:
Calcium: Can be taken together; D3 in this formula enhances calcium absorption. If already taking calcium supplements, monitor total intake.
Tetracycline / Fluoroquinolone antibiotics: Magnesium may reduce absorption — allow 2 hours before or after the antibiotic dose.
Magnesium-containing antacids: Combining may lead to excess magnesium intake.
Other D3 supplements: If taking D3 from multiple sources, calculate total intake to stay within tolerable upper intake levels.
If unsure about interactions, consult a pharmacist before use.
How quickly does Blackmores Magnesium work?
The timeline for noticing effects from Blackmores Magnesium varies by individual:
Weeks 1–2: Those deficient in magnesium may notice reduced muscle tension and better rest
Weeks 4–8: Magnesium levels begin to stabilise; nervous system and muscle function improve progressively
Bone health (D3): Vitamin D3 effects on bone require months to years due to slow bone remodelling processes
Regular, consistent use is recommended for lasting benefits.

Be cautious when combining with Tetracycline and Fluoroquinolone antibiotics (allow 2-hour gap), magnesium-containing antacids (risk of excess intake), and certain diuretics. If taking regular medications, consult a pharmacist first.
Excessive magnesium from supplements may cause diarrhoea, nausea, and stomach cramps. Very high intake may lead to hypermagnesemia (elevated blood magnesium), especially in people with kidney disease. Do not exceed the label-recommended dose.
