Product Details

What is Calcium Lactate Gluconate?

Calcium Lactate Gluconate is a versatile calcium salt compound that binds calcium ions with lactate and gluconate ions. The inclusion of lactate and gluconate ions enhances the calcium’s solubility, facilitating its absorption within the gastrointestinal tract. As such, individuals seeking to increase their calcium intake often prefer Calcium Lactate Gluconate supplements. Calcium is an essential nutrient for life and plays a crucial role in several physiological processes. It is the most abundant mineral in the human body, primarily found in the bones and teeth.

Potential Benefits of Calcium Lactate Gluconate

Calcium Lactate Gluconate and Bone Health

The body stores approximately 98% of its calcium in the bones and teeth, where it provides structural support and strength. If the body doesn’t receive enough calcium through dietary sources, it will leach it from the bones and teeth. Calcium Lactate Gluconate provides a supplemental source of calcium, aiding in the development and maintenance of strong and healthy bones and teeth. A review of scientific studies including more than 7000 participants under the age of 35 reported that calcium supplements improved bone mass.

Calcium is particularly important for menopausal and post-menopausal women. Estrogen is essential for maintaining bone density. Unfortunately, estrogen production reduces dramatically during and after menopause. Several studies found that calcium lactate gluconate supplements slowed bone loss in post-menopausal women.

Calcium Lactate Gluconate and Heart Health

Adequate calcium intake through supplements like Calcium Lactate Gluconate may contribute to improved cardiovascular health. Calcium is a critical electrolyte for maintaining cardiac muscle function and regulating heart rhythm. The heart needs calcium to contract and pump blood throughout the body. Calcium also improves blood vessel tone by helping blood vessel walls contract and relax.

Calcium Lactate Gluconate and Muscle Function

Calcium is pivotal in all muscle contraction and relaxation—not just those in the heart. It also facilitates nerve-muscle communication. As an electrolyte, it helps maintain the electrical potential and fluid balance within muscle cells. Calcium Lactate Gluconate supplements may support muscle function by reducing the likelihood of muscle cramps and spasms.

Calcium and Kidney Stones

Individuals prone to developing calcium oxalate kidney stones should not take Calcium Lactate Gluconate supplements. Calcium Citrate is a more kidney stone-friendly option. It may reduce the risk of kidney stone formation, as it can bind with oxalates in the digestive tract and prevent them from absorbing into the bloodstream. It can also increase urinary citrate, which inhibits calcium crystal formation (the precursor to kidney stone development).

Calcium Lactate Gluconate as an Antacid

Calcium has antacid properties, helping to alleviate symptoms of acid reflux and heartburn. It functions by neutralizing excess stomach acid, providing relief from gastrointestinal discomfort.

Calcium and Vitamin D to Support Weight Loss

Some research shows that increasing calcium intake alongside vitamin D may support weight loss efforts. A three-month-long study found that obese women taking a calcium and vitamin D supplement experienced more weight loss and waist size reduction compared to the control group. Another 12-week study reported similar findings. Obese college students taking a combination of calcium and vitamin D lost significantly more fat mass and visceral fat than the control group.

Potential Side Effects of Calcium Lactate Gluconate

Most individuals can take Calcium Lactate Gluconate supplements without experiencing significant side effects. Excessive calcium supplement intake may cause digestive issues, such as constipation, diarrhea, and abdominal cramps. Prolonged and excessive calcium consumption may result in hypercalcemia, a condition that can affect heart rhythm and kidney function. Taking calcium supplements as recommended can prevent these side effects.

Calcium supplements may interfere with the absorption of certain antibiotics and thyroid medications. Individuals taking prescription medication should consult a healthcare professional before starting any new supplement.
