Swisse Ultiboost Calcium + Vitamin D delivers a robust dose of calcium (1020mg) in the well-absorbed citrate form, which is favored by many nutritionists due to its efficacy and stomach-acid independent absorption. Crucially, it is paired with Vitamin D, a vital nutrient that dramatically enhances calcium absorption and its proper utilization for bone mineralization and overall health. The inclusion of Vitamin D directly addresses a key nutritional synergy, making it a more effective and complete calcium supplement compared to standalone calcium products. Its competitive price per serving, combined with a reputable brand and a respectable review count, positions it as a strong and balanced contender in the market, offering good value for comprehensive bone support.
