Buying advice

When choosing a calcium supplement, consider the form (carbonate vs citrate) based on your stomach sensitivity and absorption needs. Look for added vitamin D and K2 for better bone health. Check for third-party testing to ensure purity and potency. Avoid megadoses; spread intake throughout the day for optimal absorption.
