Should I take calcium?

Our sources indicate that optimizing calcium intake is important for bone mineral density, especially for individuals with lower bone density or those in premenopausal/postmenopausal stages, as noted by Bryan Johnson.

Paul Saladino frequently highlights calcium's role in supporting colonic oxalate excretion and preventing bone loss, suggesting that many people are calcium deficient due to high oxalate consumption.

Peter Attia and Paul Saladino agree that bioavailable forms like calcium hydroxyapatite are effective, with Saladino emphasizing the superiority of microcrystalline hydroxyapatite complex over calcium carbonate for preventing bone loss.

To ensure adequate calcium intake, sources suggest consuming dietary sources like raw dairy, bone matrix, or bone meal. For supplementation, microcrystalline hydroxyapatite complex or calcium citrate are mentioned, with a specific note from Rhonda Patrick about a Swanson calcium/magnesium supplement (600mg calcium, 300mg magnesium). Eating bones, including those in bone broth or small animal bones, also provides bioavailable calcium. Balancing calcium and phosphorus intake is beneficial, especially with high-phosphorus diets from meat.

• 02Paul Saladino noted that supplementing with a multi-mineral supplement rich in alkaline minerals (calcium, magnesium, potassium) can increase urinary pH from 5.94 to 6.57, while keeping blood pH stable.
• 03Paul Saladino claimed that calcium supplementation can support colonic oxalate excretion, especially when kidneys are struggling due to high oxalate levels and acidity.
