Calcium Citrate

Calcium citrate from Greatlife is our top-quality calcium supplement. It’s a powerful formula that supports bone health, muscle function, and nerve signalling. Calcium is essential for maintaining a strong skeletal structure and healthy teeth, as well as for ensuring normal muscle function and neurotransmission. Calcium citrate offers high bioavailability and is efficiently absorbed even with low stomach acid, making it an excellent choice for individuals of all ages.

Biologically, calcium plays a key role in the body’s mineral balance, blood clotting, and cell division processes. It is required to maintain normal calcium levels in the blood and supports the function of digestive enzymes, contributing to a well-functioning metabolism.

Studies have shown that calcium citrate is one of the most easily absorbed forms of calcium, making it an ideal choice for those looking to support bone health, improve muscle performance, and promote nervous system function.

Why Choose Calcium Citrate?

Calcium citrate offers several advantages over other forms of calcium, such as calcium carbonate, calcium gluconate, calcium malate, and calcium glycinate:

Better Absorption

• Calcium citrate is absorbed more effectively than calcium carbonate, especially when stomach acid production is low.
• As it does not require stomach acid for dissolution, it can be taken with or without food.

Suitable for People with Low Stomach Acid

• Older adults and those with conditions such as gastritis, atrophic gastritis, or who are taking acid-suppressing medications (PPIs and H2 blockers) often have low stomach acid production, making calcium carbonate harder to absorb.
• Calcium citrate is more bioavailable for these groups.

Lower Risk of Constipation

• Calcium carbonate can cause constipation and bloating, whereas calcium citrate is generally gentler on the digestive system.

Reduced Risk of Kidney Stones

• Calcium carbonate can increase the risk of kidney stones in some individuals by raising calcium levels in the urine.
• Calcium citrate may help reduce this risk by binding oxalates in the gut, preventing the formation of calcium oxalate stones.

Greater Solubility

• Calcium citrate is more water-soluble than calcium carbonate, which may make it easier for the body to utilise.
• This also makes it suitable for people with malabsorption conditions, such as coeliac disease or Crohn’s disease.

No Impact on Stomach Acid Levels

• Calcium carbonate neutralises stomach acid and may negatively affect digestion with long-term use.
• Calcium citrate does not have this effect and does not impair digestion.

Compared to Calcium Malate and Calcium Glycinate

• Calcium citrate may be a better option than calcium malate and calcium glycinate for individuals with sensitive stomachs or digestive issues, as the citrate form is more soluble and easier to absorb without affecting stomach acid levels.
• Calcium malate and calcium glycinate may contain binders that can sometimes cause discomfort in those with sensitive stomachs or intestines.
