To avoid weakening your muscle mass and bone density during weight loss or menopause, it is important to eat sufficiently and, if necessary, turn to a targeted supplement like AlgaeCal, which is presented as the only calcium supplement clinically proven to increase bone density.

Abbey Sharp's warning regarding restrictive diets is highly relevant: severe calorie restriction or ultra-rapid weight loss effectively weakens bone density and reduces muscle mass, a phenomenon well-documented by nutrition research. Similarly, the accelerated decline in bone density in women during menopause is an indisputable biological reality. However, the claim that AlgaeCal is the only calcium supplement proven to increase bone density requires nuance. The brand relies notably on a 2011 clinical study and a 7-year follow-up published in the Journal of the American College of Nutrition (JACN), showing an increase in bone density. However, these open-label studies without a double-blind placebo group often combine calcium with strontium intake. This mineral accumulates in the bones and has the effect of artificially overestimating density measurements during routine imaging tests. Finally, other forms of calcium combined with key vitamins (such as vitamins D3 and K2) also benefit from strong clinical evidence to support the strength of our skeleton over the years.
