Name and Basic Overview

NOW Foods Calcium Lactate is a dietary supplement designed to support bone health by providing a bioavailable source of calcium. Calcium lactate is a salt formed from lactic acid and calcium, often derived from fermentation processes, making it suitable for vegetarian and vegan diets. People commonly seek calcium supplements to maintain bone density, support dental health, and ensure proper muscle and nerve function.

Historical Background / Traditional Use

Calcium has been recognized for its importance in bone health for centuries, with traditional uses in various cultures to support skeletal strength. Historically, calcium sources were primarily dietary, obtained from dairy products, leafy greens, and certain fish. The use of calcium lactate as a supplement is a more modern development, providing a convenient and efficient way to meet calcium needs without relying solely on dietary intake.

Composition and Active Components

The primary active component in this supplement is elemental calcium, derived from calcium lactate. Each tablet provides 255 mg of elemental calcium. Calcium plays a crucial role in the body by contributing to the mineralization of bones and teeth, facilitating muscle contraction, and supporting nerve transmission and vascular function.

Research and Evidence Base

Numerous studies have established the importance of calcium in maintaining bone health and preventing osteoporosis, particularly in postmenopausal women and older adults. Research indicates that calcium lactate is a bioavailable form of calcium, meaning it is efficiently absorbed and utilized by the body. This makes it a suitable option for individuals who may have difficulty absorbing other forms of calcium. While the evidence supporting calcium's role in bone health is robust, it is important to note that excessive calcium intake can lead to adverse effects, such as kidney stones. Therefore, supplementation should be tailored to individual needs, ideally under the guidance of a healthcare professional.

Potential Health Benefits

• Supports Bone Health: Calcium is crucial for maintaining bone density and strength, reducing the risk of osteoporosis, especially in postmenopausal women and the elderly.
• Bioavailable Calcium Source: Calcium lactate is known for its good absorption rate, making it an effective option for those needing to increase their calcium intake.
• Muscle and Nerve Function: Adequate calcium levels are essential for proper muscle contraction and nerve transmission, supporting overall muscular and neurological health.
• Vascular Function: Calcium plays a role in maintaining normal blood vessel function, which is vital for cardiovascular health.

Safety, Side Effects, and Precautions

• Gastrointestinal Upset: Some individuals may experience mild gastrointestinal issues such as constipation or bloating when taking calcium supplements.
• Hypercalcemia Risk: Excessive calcium intake can lead to hypercalcemia, a condition characterized by elevated calcium levels in the blood, potentially causing kidney stones or impaired kidney function.
• Specific Populations: Pregnant or breastfeeding women, children, and individuals with kidney disease should consult a healthcare provider before using this supplement.
• Allergies: Although rare, some individuals may have allergic reactions to calcium supplements.
