What the Evidence Says

✨ AI-generated · Qwen 3.6 · methodology

Vitamin D is widely studied for supporting cognitive function and bone health. Evidence for apoaequorin's efficacy in cognitive support is limited, as there are few peer-reviewed clinical trials available. Overall, the evidence coverage for this specific ingredient combination is very low.
