9.9 million people in Pakistan have osteoporosis and 7.2 million of them are women. That’s not a made-up statistic. It comes from a 2018 study published in the Annals of Medicine and Surgery, which also found that Pakistan ranks 5th in the world for osteoporosis cases.
Now here’s the problem. The average Asian adult consumes only 300-450 mg of calcium daily. The body needs 1000-1300 mg. That’s a daily deficit of 550-1000 mg and your bones are paying the price.
This is exactly why CaC 1000 Plus has become Pakistan’s most trusted calcium supplement. Let’s break down everything you need to know about this effervescent tablet.
What is CaC 1000 Plus?
CaC 1000 Plus is an effervescent calcium supplement manufactured by Haleon (formerly GSK). It’s the #1 prescribed calcium brand by doctors in Pakistan and comes in a convenient fizzy tablet format that dissolves in water.
The supplement combines “double calcium” with essential vitamins to address nutritional deficiencies and support bone health.
CaC 1000 plus flavours include Orange, Lemon, Cola, and Mango (Sugar-Free).
CaC 1000 Plus Ingredients

Each CaC 1000 Plus tablet contains:
| Ingredient | Amount |
| Calcium Lactate Gluconate | 1000 mg |
| Calcium Carbonate | 327 mg |
| Vitamin C (Ascorbic Acid) | 500 mg |
| Vitamin D3 | 400 I.U. (10 mcg) |
| Vitamin B6 | 10 mg |
The “double calcium” formula combines two highly bioavailable forms of calcium, Calcium Lactate Gluconate and Calcium Carbonate, to maximize absorption.
CaC 1000 Plus Benefits

1. Strengthens Bones and Teeth
Calcium is the primary building block of bones and teeth. CaC 1000 Plus provides enough calcium to meet daily requirements. It helps prevent conditions like osteoporosis, osteomalacia (bone softening), and osteopenia (low bone density).
2. Enhanced Calcium Absorption
Many calcium supplements fail because the body can’t absorb the calcium properly. CaC 1000 Plus includes 400 I.U. of Vitamin D3, which is essential for calcium absorption in the intestines. Without adequate vitamin D, bones cannot utilize calcium effectively.
3. Immune System Support
The 500 mg of Vitamin C in each tablet supports immune function, acts as an antioxidant, and helps fight fatigue. Vitamin C also aids in collagen formation, which is crucial for healthy bones and connective tissue.
4. CaC 1000 Plus Benefits for Skin
Vitamin C plays a key role in collagen production, the protein that keeps skin firm and elastic. Although CaC 1000 Plus isn’t specifically a skin supplement, the vitamin C content may support skin health indirectly by aiding tissue repair.
Note: Claims about CaC 1000 Plus for skin whitening are not scientifically supported. Vitamin C can brighten skin when applied topically, but oral supplements work differently.
5. Safe During Pregnancy and Lactation
Pregnant and breastfeeding women have higher calcium demands. The American College of Obstetricians and Gynecologists (ACOG) recommends calcium supplementation (1000 mg daily) during pregnancy and lactation, particularly for women with low dietary intake. Always consult your doctor before starting any supplement.
