Our verdict
Calcium and magnesium in 1:1 ratio per 15 mL serving with vitamin D3 of Calcium + Magnesium (1:1 ratio) + Vitamin D3 per liquid from Integrative Therapeutics. Best for adults…
Why we recommend this
Liquid mineral supplements are clinically preferred for older adults or those with low stomach acid who absorb mineral salts better in solution. The triple-combination of calcium, magnesium, and vitamin D3 in one berry-flavoured liquid dose is convenient and lowers pill burden — a key consideration in adherence for bone-health protocols.

What to watch out for
The 1:1 calcium-to-magnesium ratio is lower in calcium than the standard dietary recommendation of 2:1 for most adults, which may leave calcium needs underserved from this product alone. Users should account for dietary calcium when assessing overall intake.

Are there any potential interactions with medications?
Are there any potential interactions with medications?
Calcium can reduce absorption of certain medications including thyroid hormone (levothyroxine), bisphosphonates, and some antibiotics — separate by at least 2–4 hours. Magnesium may enhance the effect of blood pressure medications. Vitamin D3 at standard supplemental doses (400–2000 IU) is generally safe alongside most medications; consult your doctor if on calcium-channel blockers or diuretics.
Are there any side effects from long-term use?
Are there any side effects from long-term use?
Calcium and magnesium at supplemental doses appropriate to fill dietary gaps are well tolerated long-term for most adults. Excess calcium supplementation (>2500 mg/day total) has been associated with cardiovascular concerns in some research; keeping total daily calcium within recommended ranges is important. Magnesium above 350 mg supplemental may cause loose stools in sensitive individuals.
Does it cause any digestive issues or side effects?
Does it cause any digestive issues or side effects?
The liquid citrate form is gentler on digestion than calcium carbonate tablets, which require high stomach acid for absorption. Magnesium in the bisglycinate or citrate form used in quality liquid formulas is less likely to cause the osmotic laxative effect seen with magnesium oxide. A small number of users report mild GI adjustment in the first few days.
Can it be taken with other supplements or vitamins?
Can it be taken with other supplements or vitamins?
The berry liquid combines well with most supplement routines. Vitamin K2 (MK-7) is a logical complement — it directs calcium into bone rather than soft tissue — but is not included in this formula. Avoid taking simultaneously with iron supplements, as calcium can inhibit non-haem iron absorption; separate by at least 2 hours.
Are there any specific instructions for taking it safely?
Are there any specific instructions for taking it safely?
Shake well before each use. Adults take 1 tablespoon (15 mL) once daily with food, or as directed by a healthcare professional. Do not exceed the recommended dose. Keep refrigerated after opening. Not recommended for children without paediatric medical guidance.
How long until benefits are typically experienced?
How long until benefits are typically experienced?
Mineral supplementation for bone health operates on a long-term timeline — meaningful improvements in bone mineral density require months to years of consistent intake. Magnesium's muscle-relaxation and sleep-quality benefits may be noticed within 2–4 weeks. Vitamin D3 sufficiency (>30 ng/mL serum) typically requires 4–8 weeks of consistent supplementation if starting deficient.
