\"youngShare on Pinterest<\/a>Vitamin D supplements in pregnancy could boost cognitive health in offspring, a new study has found. Image credit: Nikola Stojadinovic\/Getty ImagesVitamin D is an important nutrient in the body, supporting bone, muscle, and immune system health. Past studies also show that vitamin D may help protect the body from certain diseases, like cognitive impairment and dementia. A new study has found that taking a high dose of vitamin D3 during pregnancy may help set up offspring for better cognitive health by age 10. <\/p>\n

Vitamin D<\/a> is an important nutrient in the body as it plays a large role in bone<\/a> and muscle health, as well as immune system support. <\/p>\n

Now, a new study published in the journal JAMA Network Open<\/a> has found that taking a high dose of vitamin D3 during pregnancy may help set the offspring up for better cognitive health by age 10. <\/p>\n

During pregnancy, mother participants had taken either a high-dose of 2,800 International Units per day (IU\/d) or standard-dose (400 IU\/d) vitamin D3 supplement<\/a> from week 24 to their first week postpartum<\/a>. <\/p>\n

At the study\u2019s conclusion, researchers found a positive association between high-dose vitamin D3 supplementation during pregnancy to a child\u2019s visual memory, verbal memory<\/a>, and flexibility<\/a> by age 10.<\/p>\n

Medical News Today had the opportunity to speak with Sheryl Ross, MD<\/a>, a board-certified ob-gyn and Women\u2019s Health Expert at Providence Saint John\u2019s Health Center in Santa Monica, CA, about this study.<\/p>\n

Ross, who was not involved in the research, commented that seeing this new study makes her even more excited about the superpowers of vitamin D, which has always behaved more than just a typical vitamin. <\/p>\n

\u201cVitamin D has always gone above and beyond bone, muscle, and immune support as a vitamin,\u201d Ross detailed. \u201cIts collateral health benefits of potentially preventing chronic diseases, cognitive decline, dementia, and depression for people is exciting, especially if some of the cognitive benefits are being passed onto the baby.\u201c<\/p>\n

\u201cMore research on how vitamin D can help the cognitive health of the baby is needed,\u201c she cautioned, \u201cbut this initial study is an exciting beginning.\u201d <\/p>\n

\u201cVitamin D receptors are all over the body including the memory center, called the hippocampus<\/a>, in the brain. It also has a role in developing neurons<\/a>, dopamine and serotonin<\/a> production, anti-inflammatory protection, and defending against oxidative stress<\/a> that can negatively affect brain function. Having adequate Vitamin D levels helps support memory, learning, and cognitive functioning. It makes sense that in the developing brain of a baby, having adequate vitamin D levels support overall cognitive functioning.\u201d <\/p>\n

\u201cThis study was the perfect segway to make the connection between adequate maternal vitamin D levels and improved long-term cognitive functioning for developing babies,\u201d she noted.<\/p>\n

\u201cMore research could be done introducing a diversified patient cohort, longer-term follow-up beyond 10 years, monitoring vitamin D levels prior to pregnancy and using advanced brain imaging (MRI)<\/a> on the developing baby to identify areas of the brain most responsive to vitamin D,\u201d suggested the ob-gyn.<\/p>\n

Monique Richard<\/a>, MS, RDN, LDN, a registered dietitian nutritionist and owner of Nutrition-In-Sight, offered some expert tips on how best to increase vitamin D3 intake during pregnancy.<\/p>\n

\u201cVitamin D continues to be one of the most common nutrient insufficiencies I see as an RDN,\u201d Richard said.<\/p>\n

\u201cFood-first recommendations remain an important priority, but it can be difficult to obtain adequate vitamin D from food alone depending on the dietary pattern, access and body\u2019s ability to absorb, convert and use,\u201d she noted.<\/p>\n

She listed out some of the best food sources for vitamin D, which include: <\/p>\n

\u201cMany of these foods are also rich in fatty acids<\/a>, vitamin C<\/a>, choline<\/a>, potassium<\/a>, magnesium<\/a>, and B vitamins<\/a> that further support maternal and child health by supporting brain function, cell reproduction and development, immune system support, and more,\u201d Richard explained.<\/p>\n

\u201cFrom a practical nutrition standpoint, consistency matters most \u2014 along with individualized testing and recommendations from a healthcare professional,\u201c she added.<\/p>\n

\u201cIf supplements are suggested, the brand, source, quality of the product, form and delivery method as well as dose, frequency, duration and timing \u2014 [\u2026] when these are taken, with what and when during the day \u2014 are equally important to address and be done in collaboration with the RDN and healthcare team,\u201d Richard advised.<\/p>\n

\u201cA balanced approach includes sensible sun exposure when appropriate, vitamin D-rich foods, fortified foods, and supplements, if, and as needed \u2014 with reassessment and big picture evaluation being followed \u2014 particularly for higher-risk groups or those with documented insufficiency,\u201d she emphasized.<\/p>\n

Casting some final reflections on the study findings, Meridan Zerner<\/a>, MS, RDN, CSSD, LD, CHWC, founder of Meridan Zerner Nutrition in Dallas, TX, who was not involved in this research, told MNT that while these results seem encouraging, the data is nuanced, and the current guidance would likely not change based on one secondary analysis.<\/p>\n

\u201cThere are several unmeasured contributors and the demographic base is not reflective of a wide population,\u201d Zerner continued.<\/p>\n

\u201cThe dose of [vitamin] D is higher than the American College of Obstetricians and Gynecologists (ACOG) recommendations<\/a> of 600 IUs for prenatal care, and 400 IUs are often found in a prenatal vitamin assuming, some [vitamin] D will come from the diet as well,\u201d she pointed out.<\/p>\n

\u201cOther guidelines would need to be carefully assessed [on a] person by person [basis] before recommending a much higher dose,\u201d Zerner concluded.<\/p>\n","protected":false},"excerpt":{"rendered":"Share on PinterestVitamin D supplements in pregnancy could boost cognitive health in offspring, a new study has found.…\n","protected":false},"author":2,"featured_media":660931,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[61],"tags":[4994,97,269,1199],"class_list":["post-660930","post","type-post","status-publish","format-standard","has-post-thumbnail","category-nutrition","tag-brain-health","tag-health","tag-nutrition","tag-vitamin-d"],"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/posts\/660930","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/comments?post=660930"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/posts\/660930\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/media\/660931"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/media?parent=660930"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/categories?post=660930"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/tags?post=660930"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
