MAXICAL 30TAB

Benefits & Uses

Primary Benefit

Supports bone health, calcium absorption, and vitamin D3 replenishment

Health Claims

Contributes to normal bone and teeth maintenance; supports calcium absorption and utilization; helps maintain normal muscle function; supports immune system function; reduces risk of osteoporosis when combined with adequate diet and physical activity

Common Deficiency Symptoms

Calcium deficiency: muscle cramps, numbness, brittle nails, osteoporosis; Vitamin D deficiency: fatigue, bone pain, muscle weakness, frequent infections, rickets in children

Target Population

Adults over 50, postmenopausal women, individuals with low dietary calcium intake, people with limited sun exposure, pregnant and breastfeeding women, individuals at risk of osteoporosis

Scientific Evidence Level

Strong

Onset Timeline

Vitamin D blood levels improve within 2-4 weeks of supplementation; measurable improvements in bone density typically require 6-12 months of consistent use

Usage & Dosage

Suggested Use

Take one tablet daily, preferably with a meal.

Serving Size

1 tablet

Servings Per Container

30

Best Time to Take

With meals

Recommended Daily Intake

Calcium: 1000-1200mg/day for adults; Vitamin D3: 600-800 IU/day for adults (up to 1500-2000 IU/day for deficiency correction)

Upper Tolerable Limit

Calcium: 2500mg/day for adults 19-50 years, 2000mg/day for adults 51+; Vitamin D3: 4000 IU/day for adults

Absorption Enhancers

Take with a fat-containing meal to enhance vitamin D3 absorption; adequate stomach acid improves calcium carbonate dissolution; magnesium supports vitamin D metabolism

Absorption Inhibitors

Antacids and proton pump inhibitors reduce calcium carbonate absorption; high-oxalate foods (spinach, rhubarb) and phytates (whole grains) inhibit calcium absorption; caffeine and excess sodium increase urinary calcium loss

Side Effects

Possible Side Effects

Constipation, bloating, and gas are common with calcium carbonate; high doses may cause hypercalcemia, hypercalciuria, nausea, and kidney stones; vitamin D3 toxicity at excessive doses may cause anorexia, vomiting, and weakness

Upper Tolerable Limit

Calcium: 2500mg/day for adults 19-50 years, 2000mg/day for adults 51+; Vitamin D3: 4000 IU/day for adults

Safety & Warnings

Contraindications

Hypercalcemia; hypercalciuria; nephrolithiasis (calcium-containing kidney stones); vitamin D toxicity/hypervitaminosis D; severe renal impairment; conditions predisposing to hypercalcemia (e.g., hyperparathyroidism, sarcoidosis)

Pregnancy Safety

Consult Doctor

Breastfeeding Safety

Safe (at recommended doses; avoid excessive dosing and monitor if high-dose vitamin D/calcium is used)

Children Suitability

Consult a healthcare provider for appropriate dosing in children; adult formulation not specifically indicated for pediatric use

Interactions

Medication Interactions

Calcium carbonate reduces absorption of tetracyclines, fluoroquinolones, bisphosphonates, levothyroxine, and iron supplements - take these medications 2 hours apart; thiazide diuretics increase risk of hypercalcemia; corticosteroids reduce calcium absorption; vitamin D3 enhances digoxin sensitivity

Supplement Interactions

Calcium competes with iron and zinc for absorption - take separately; magnesium and calcium compete at high doses; avoid concurrent use with high-dose vitamin A supplements

Synergistic Nutrients

Vitamin D3 + Calcium for bone mineralization; Vitamin K2 (MK-7) directs calcium to bones and away from arteries; Magnesium activates vitamin D and supports bone matrix; Phosphorus works with calcium for bone structure

Special Populations

Target Population

Adults over 50, postmenopausal women, individuals with low dietary calcium intake, people with limited sun exposure, pregnant and breastfeeding women, individuals at risk of osteoporosis

Children Suitability

Consult a healthcare provider for appropriate dosing in children; adult formulation not specifically indicated for pediatric use

Pregnancy Safety

Consult Doctor

Breastfeeding Safety

Safe (at recommended doses; avoid excessive dosing and monitor if high-dose vitamin D/calcium is used)

Storage & Patient Advice

SFDA Storage Conditions

store below 30°c

Storage Conditions

Store below 30°C; keep the bottle tightly closed and protect from moisture and direct light.

Patient Counseling

Take MAXICAL (calcium carbonate + vitamin D3) with food (preferably with a meal) to improve calcium carbonate absorption and reduce GI upset; separate from levothyroxine, iron, bisphosphonates, and certain antibiotics (e.g., tetracyclines/fluoroquinolones) by at least 2-4 hours; maintain adequate fluid intake to reduce constipation and kidney-stone risk; do not exceed the recommended total daily calcium intake from all sources unless directed by a clinician, and seek medical advice if you have kidney stones, hypercalcemia, or significant renal impairment.

Science & Evidence

Bioavailability Form

Calcium Carbonate requires gastric acid for dissolution - best absorbed with food; Cholecalciferol (D3) is the preferred form for raising and maintaining serum 25(OH)D levels, approximately 87% more potent than D2

Water or Fat Soluble

Vitamin D3 is fat-soluble; Calcium Carbonate is neither water-soluble nor fat-soluble (it is an inorganic salt). The combination product contains one fat-soluble component (vitamin D3) and one mineral component (calcium carbonate).

Scientific Evidence Level

Strong

Onset Timeline

Vitamin D blood levels improve within 2-4 weeks of supplementation; measurable improvements in bone density typically require 6-12 months of consistent use

Food Sources

Calcium: dairy products, fortified plant milks, sardines, broccoli, kale, almonds; Vitamin D3: fatty fish (salmon, mackerel), egg yolks, fortified milk, cod liver oil, UV-exposed mushrooms
