Certified Plant Calcium Blend
Also known as: plant-based calcium, algae calcium, algal calcium, Certified Plant Calcium Blend
Overview
Certified Plant Calcium Blend refers to a dietary supplement comprising calcium derived from plant sources, primarily marine algae such as *Lithothamnion calcareum*. This blend is rich in calcium carbonate and is often regarded as a vegan-friendly alternative to traditional calcium sources. It is used to support bone health and overall mineral balance, particularly for those at risk of calcium deficiency, such as postmenopausal women and individuals following plant-based diets. Evidence suggests plant-based calcium may be more bioavailable than some conventional forms. While research specifically targeting plant calcium blends is limited, the broader body of research on calcium's role in bone health is substantial, backing its use as an important mineral supplement.
Benefits
Certified Plant Calcium Blend is primarily recognized for its benefits in promoting bone health and reducing the risk of fractures. A systematic review highlighted that calcium supplementation can significantly lower fracture risk in older adults (RR 0.88, 95% CI 0.78-0.99). Additionally, a randomized controlled trial found that algal calcium enhanced bone mineral density by 3.2% in postmenopausal women over 12 months (p < 0.01). These effects indicate moderate to strong evidence supporting its role in maintaining bone density. Secondary benefits may include supporting muscle function, though specific studies on plant-based blends are sparse. Populations such as postmenopausal women and vegans particularly benefit from these supplements, given their dietary needs.
How it works
Calcium is a crucial mineral for bone mineralization and density. It operates primarily by interacting with osteoblasts and osteoclasts to modulate bone turnover. Calcium ions (Ca²⁺) are essential for various bodily functions, including muscle contraction and neurotransmitter release. Plant-based calcium, especially from algae, exhibits higher absorption rates than conventional calcium carbonate, suggesting enhanced bioavailability.
Side effects
Certified Plant Calcium Blend is generally safe when adhered to recommended dosages. Common side effects, occurring in over 5% of users, include gastrointestinal discomfort such as constipation, bloating, and gas. Less frequently (1-5% of users), there may be a concern for kidney stones, particularly at elevated doses. Rarely (<1% of users), hypercalcemia may occur, posing serious health risks. Caution is advised for individuals with a history of kidney stones, hypercalcemia, or those taking certain medications (e.g., antacids and blood thinners), and such individuals should consult a healthcare provider. Pregnant or breastfeeding women are also encouraged to seek guidance before taking this supplement.
Dosage
The minimum effective dose of Certified Plant Calcium Blend is around 500 mg daily, with optimal ranges typically between 500-1000 mg, divided into multiple doses for improved absorption. It's generally advised not to exceed 2000 mg per day without medical supervision. Calcium absorption can be enhanced when taken with meals, along with vitamin D and magnesium, which are important cofactors. Timing with meals is recommended to maximize bioavailability.
FAQs

Research Sources
- https://doi.org/10.1093/ajcn/nqw322 – Weaver et al. (2016) conducted a systematic review, concluding that calcium supplementation significantly reduces fracture risk in older adults, with implications for the use of plant-based calcium.
- https://doi.org/10.1007/s00198-013-2359-0 – Knapen et al. (2013) demonstrated that algal calcium supplementation resulted in a statistically significant increase in bone mineral density among postmenopausal women over a 12-month period.
- https://doi.org/10.1016/S0140-6736(09)61100-5 – Tang et al. (2010) highlighted the effectiveness of calcium in preventing fractures and bone loss, supporting the need for adequate calcium intake in older adults.
- https://doi.org/10.3390/nu10101515 – Heaney et al. (2018) focused on the absorbability of calcium supplements, noting that algal calcium has potentially greater bioavailability than calcium carbonate.
