Researchers found that participants taking 5,000+ IU of vitamin D daily had a marginally significant association with higher total Montreal Cognitive Assessment (MoCA) scores compared with those who did not take vitamin D daily. Ultimately, the researchers concluded that taking higher doses of daily vitamin D supplementation is associated with \u201cbetter overall cognitive performance\u201d in this older population.<\/p>\n
Fortunately, vitamin D supplements are widely available, with plenty of reputable options on Amazon. Metagenics formula<\/a> is one popular choice, offering 5,000 IU of vitamin D3 plus vitamin K to support absorption. And for those seeking an even higher dose, the brand also offers an extra-high-potency 10,000 IU formula<\/a> as well. <\/p>\n The formula is currently just under $30 ahead of October Prime Day<\/a>, which runs from Oct. 6 to 7 this year, though many deals<\/a> are already live.<\/p>\n Many Metagenics users have echoed benefits similar to those reported in the research.<\/p>\n \u201cI am 84 years old and need energy,\u201d one Metagenics user shared. \u201cI have been taking this brand a little over a week and can tell a difference in my energy level and personality.\u201d<\/p>\n According to the brand, the formula features a bioavailable form of vitamin K2 (MK-7) alongside vitamin D3 in coconut and MCT oil to support absorption. The potent blend is also designed to support bone health and immune function. <\/p>\n \u201cI have been taking this product for four months,\u201d another reviewer, who takes the 10,000 IU formula shared. \u201cTotally believe in the importance of Vitamin D3 10,000 K and this product has worked for me as in focus, memory, no more leg cramps, etc.\u201d<\/p>\n The formula is third-party tested for purity, potency, and heavy metals and backed by more than 2,000 quality tests each year.
