Why Vitamin D Deficiency Peaks in Autumn and What to Do About it
As the days get shorter, the sun shines less and the temperatures drop, there is another seasonal change that many people may not think about: low vitamin D levels. Most of us know that we can make vitamin D from the sun, but it’s so easy to forget that depending on where you live, many people don’t get enough sun to make adequate vitamin D during certain parts of the year, typically starting in fall. Technically, vitamin D deficiency does not “peak” in early autumn. Research shows that vitamin D levels often are at their lowest point in winter or early spring, but fall is the critical season to be thinking about vitamin D and taking proactive steps to prevent deficiency later on.1 Why does this matter? Because vitamin D is critical for bone health, the immune system, inflammation, and so much more. Read on to get the tools you need to be prepared to prevent vitamin D deficiency this autumn and beyond. Why Autumn and Winter Dramatically Reduce Vitamin D Production The amount of vitamin D your skin can produce depends on a few factors. First there’s the sun. During fall and winter, when the sun sits lower in the sky, the UV rays are not as strong as they are in summer. Additionally, the days are shorter, offering less time during the day to get exposed to the sun’s light. Second, we are typically more covered up in the colder months, so there’s less surface area of the skin getting direct sunlight. And third, we are indoors more. All of these factors mean less vitamin D production. There can be other factors as well, such as age, genetics, medical conditions and more that can influence vitamin D levels. People who are the most susceptible to low vitamin D may fit into one or more of these categories:2 Liver at northern latitudes Spend little time outdoors Regularly cover most of their skin Have darker skin pigmentation (darker skin is better at blocking UV light) Are older adults Have conditions or medications affecting fat absorption (fat helps vitamin D absorb better) And because relatively few foods naturally contain substantial amounts of vitamin D, it can be difficult to make up the difference from diet alone. Common Signs That Your Vitamin D Levels May Be Low One of the challenges with vitamin D is that it does not always produce obvious symptoms. Many live with mild deficiency that may cause no noticeable symptoms at all.3 But if the deficiency gets worse, there are some common signs you might see:3,4 Muscle weakness Muscle aches Bone and back pain Fatigue Reduce physical performance Mood changes (sadness, depression, irritability) Frequent illness Vitamin D is particularly important for bone health because it helps the intestines absorb calcium and support normal bone mineralization. This is especially critical during the menopause years when our bone density can take a hit. Research also associates adequate vitamin D levels with maintaining muscle function.4 Research also suggests vitamin D has a role to play in a properly functioning immune system. This is why you commonly see vitamin D included in vitamins for the immune system and other immune support supplements.5 If you are one of those people that frequently get sick or experience any of these symptoms listed, considering getting your vitamin D levels checked. A high-quality vitamin D supplement can fill the gap and get you on the path to restoring those levels for optimal health. Why Vitamin D and K2 Work Better Together Than Alone When it comes to bone health supplements, vitamin D often gets most of the attention, But vitamin K is also up there when it comes to important nutrients for bone health. They have separate yet complementary roles. Think of their partnership this way:4,6 Vitamin D helps you absorb calcium: It increases the body’s ability to absorb calcium from the digestive tract so that calcium can get where it needs to go – namely the bones. Vitamin K helps activate proteins involved in binding calcium to the bone matrix. One of these is osteocalcin, a vitamin K-dependent protein needed for bone mineralization. This unique relationship is why the best bone health supplements have both. As you might expect, Body Kitchen understands these roles and offers both nutrients combined conveniently in one capsule, helping you prevent deficiency and achieve optimal bone health and overall body support. But please note: anyone taking warfarin or other medications that can be affected by vitamin K need to talk with their doctor first before adding vitamin K2 or any other supplements. How to Choose the Right Vitamin D Supplement Heading into Winter If a vitamin D supplement sounds like something you want to consider, here are a few things to look for so you make the right choice: The type of vitamin DTypically we mention vitamin D3, but did you know there is also vitamin D2 in some supplements? Most people should choose D3 as it’s more potent and arguably better absorbed. A recent study found that D3 was more effective than D2 at raising total vitamin D blood levels.7 Check the doseThe recommended intake for vitamin D is 600-800IU per day for adults, but some studies some studies suggest higher doses may be better.8 Taking moderate doses up to 5,000IU/ per day is safe, but always check with your doctor first to make sure it does not interfere with any medications or other treatment goals. Consider having your vitamin D levels checkedWhether you are deficient or not (and many people are) can help you determine the best product and dose. Final Thoughts Autumn is a smart time to pay attention to vitamin D since levels start declining as soon as the sun begins to dip. It’s really important not to neglect this key nutrient as it’s involved in bone health, muscle function, the immune system and overall health. Be sure to check out Body Kitchens Vitamin D + K2 for the best combo for bone health and beyond. Proper vitamin D levels will make sure you go into autumn and winter fully armed and feeling your best. And if in doubt – get your vitamin D levels checked! Frequently Asked Questions Why does vitamin D deficiency become more common in autumn and winter? Vitamin D is primarily synthesized in the skin through direct exposure to UVB sunlight. In autumn and winter, the sun sits lower in the sky, UVB rays travel through more of the atmosphere, and people spend significantly less time outdoors. In many northern latitudes, the angle of the sun from October through March means that UVB exposure is insufficient for meaningful vitamin D production even on clear days. Combined with shorter days and more time spent indoors, this seasonal shift causes vitamin D levels to drop for a large portion of the population. What are the most common signs that vitamin D levels may be low? Vitamin D deficiency is often subtle and easy to attribute to other causes. Common signs include persistent fatigue, low mood or seasonal blues, muscle weakness, frequent illness, and bone or joint discomfort. Because vitamin D plays a role in immune function, mood regulation, muscle health, and calcium metabolism, deficiency can affect multiple systems at once. A blood test measuring serum 25-hydroxyvitamin D is the most reliable way to confirm a deficiency rather than relying on symptoms alone. What does vitamin K2 have to do with vitamin D supplementation? Vitamin D increases the absorption of calcium from the gut, but calcium needs to be directed to the right places in the body. Vitamin K2 activates proteins that guide calcium into bones and teeth rather than allowing it to deposit in soft tissues like arteries and blood vessels. When vitamin D supplementation is taken without adequate K2, calcium absorption increases but without the directional guidance that K2 provides. Combining D3 with K2 supports both effective calcium utilization and cardiovascular safety. How much vitamin D do most adults need during autumn and winter months? The amount of vitamin D needed varies by individual based on baseline blood levels, body weight, age, and how much sun exposure a person gets. General guidance suggests that many adults benefit from 1,000 to 2,000 IU of vitamin D3 daily during low-sun months, with some individuals requiring higher amounts under the guidance of a healthcare provider. Because vitamin D is fat-soluble and accumulates in the body, it is worth checking blood levels before significantly increasing intake, and taking it with a meal that contains dietary fat improves absorption. Who is most at risk for vitamin D deficiency heading into fall? People at greatest risk of autumn vitamin D deficiency include those who live at higher latitudes, spend most of their time indoors, have darker skin tones that require more sun exposure for adequate synthesis, are over 65 (as skin becomes less efficient at producing vitamin D with age), and those who are overweight, since vitamin D is stored in fat tissue and may be less bioavailable. People who wore sunscreen consistently through summer may also have lower stored levels than expected, making a fall supplement routine particularly important for this group.

Fall Skincare From Within: How To Prep Your Skin for Cold Weather
As fall rolls in and temperatures and humidity begin to drop, our skin can become noticeably drier, more rough, and even less soft. Add indoor heating, hot showers and less air flow, these colder months can really be challenging for maintaining proper skin health.1 But there are steps we can take to prep our skin for these inevitable changes. While there’s plenty of advice on what to put on our skin, from creams and moisturizers to serums and balms, it’s arguably more important how we support our skin health from the inside. Supporting youthful skin with an adequate diet, alongside key supplements such as elastin and collagen peptides, can help provide skin support at a much deeper level than topical products alone. Let’s take a look. Why Cold Weather Takes a Toll on Skin Elasticity and Hydration We often take our skin for granted, but it’s constantly defending us against the outside world while we carry on with our day. It functions as a protective barrier between us and the outside environment while also keeping moisture in and irritants out. But cold, dry weather can make maintaining skin firmness and skin hydration more difficult. There are several reasons why fall in particular can be tough on skin: Lower humidity, which means less moisture in the air Cold temperatures, which dries out skin Wind and cold air can mean more dryness and irritation Indoor heating, creating even less humid of an environment Long, hot showers which can strip away skin’s oils and moisture At the same time, we are slowly losing collagen and elastin, the main framework of our skin, due to normal skin aging. Cold weather and less moisture can make this loss appear even more prominent, which is why fall can be very challenging for optimal skin health. How Collagen and Elastin Supplements Support Seasonal Skin Resilience But don’t lose hope quite yet. We do have tools that can help us fight against these seasonal changes to keep our skin looking fresh and healthy. Let’s first talk collagen peptides. Think of collagen as the framework that gives skin firmness and strength. Studies have shown that hydrolyzed collagen peptides can improve visible skin hydration, elasticity and reduced skin wrinkling, even after just 12 weeks.2 Next we have elastin. Elastin gives skin its flexibility and bounce. While this compound is less studied, we do have evidence that oral marine-derived elastin supplements can improve skin hydration as well as improve skin elasticity.3 Body Kitchen understands that both offer different yet complementary roles, and that’s why we’ve added Pro-Elastin Peptides to our skin care line up, so you can include this key support alongside collagen peptides for the dual approach your skin needs. Body Kitchen’s Pro-Elastin provides 1,000 mg of marine-derived elastin peptides per serving and is designed to complement the structural role of collagen. Consider adding it this fall for the extra seasonal support your skin deserves. The Best Internal Nutrients to Fortify Skin Before Winter Arrives Don’t forget, even the best skin health supplements can’t outdo good nutrition. Your body needs a whole host of nutrients to build, maintain and protect skin health. Here are key areas to consider: Adequate protein: Collagen and elastin are proteins, so getting enough dietary protein daily helps provide the amino acids to build and repair these key proteins and so many other functions of skin health. In addition to food sources of protein, collagen peptides can help boost protein intake as well. Vitamin C: This vitamin is a key cofactor in collagen synthesis, and it also functions as an antioxidant that protects the skin from oxidative stress. Include foods such as citrus fruits, kiwi, bell peppers, and broccoli.4 Colorful plant foods: In addition to vitamin C foods, most plant foods offer an abundance of antioxidants. When you see color in food, what you really see are plant polyphenols, which help cell repair and ward off inflammation. Aim for a wide variety of colorful foods daily to get the most benefit. Healthy fats: Dietary fats are key to helping maintain skin barrier protection. Omega-3 fats in particular may be especially helpful. A 2024 study found that adding omega 3’s helped improve skin hydration and skin elasticity.5 Fatty fish, walnuts, leafy greens, flax seeds, hemp hearts and tofu are all good sources of dietary omega 3’s. Building a Fall Skin Prep Routine That Works From the Inside Out Building the best routine for fall skin health does not need to be complicated. Consistency matters more than adding more and more products to your routine. Start with these basics: Eat protein-rich foods at every meal Include vitamin C foods daily Eat a variety of colorful plant foods daily Eat omega-3 foods several times per week Stay hydrated, especially in cold weather Consider adding elastin and collagen peptides for daily support Continue using a high-quality moisturizer and daily sunscreen to protect the outside of your skin, even in winter If you decide to opt for adding additional skin support, remember Body Kitchen’s pro-elastin is the perfect complement to collagen peptides. While collagen benefits skin strength, elastin is there for elasticity. Both are key to revitalize dry, dull winter skin. But remember, as studies suggest, results don’t happen overnight. Think of internal nutrient supplementation as long-term skin health support, not a quick cosmetic fix. Final Thoughts The return to cold weather is unavoidable, but dry, dull skin doesn’t have to be. Protect your skin through the fall and beyond with just a few, intentional steps. Make sure to maintain a nutrient-rich diet with a variety of colorful plant foods, high protein choices, and omega 3 foods. Adding hydrolyzed collagen peptides and elastin peptides may offer additional support, especially when it comes to skin hydration and elasticity that can be challenging in dry, cold weather. Start supporting your skin the fall before the coldest weather arrives, and you will have a headstart on achieving skin that is firm, hydrated and resilient all season long. Frequently Asked Questions Why does skin often look and feel worse in fall and winter? Cooler air holds less moisture than warm air, and indoor heating further reduces humidity levels, both of which draw water out of the skin and compromise the skin barrier. At the same time, declining sun exposure in fall reduces vitamin D levels, which play a supporting role in skin cell renewal. For people already dealing with reduced collagen and elastin production due to age, the seasonal shift can make dryness, dullness, and fine lines noticeably more pronounced. How does elastin supplementation help the skin adapt to seasonal changes? Elastin is the protein that allows skin to flex and return to its original shape, and it plays a key role in how well skin withstands environmental stressors like low humidity and cold air. When elastin levels are supported through supplementation, skin maintains greater resilience and bounce-back even as external conditions become more challenging. An elastin supplement taken consistently in the weeks leading into fall can help build a stronger skin foundation before the harshest drying conditions arrive. What internal nutrients best support skin through cold weather months? Collagen and elastin peptides are among the most impactful internal skin nutrients for cold weather resilience. Collagen supports skin structure and volume, while elastin supports flexibility and bounce. Together, they help maintain a skin matrix that is better equipped to hold moisture and resist the thinning and tightening that cold, dry air can cause. Supporting these proteins from within, alongside adequate hydration and vitamin C intake, addresses skin health at a foundational level that topical products cannot reach. When should someone start taking a skin supplement before fall weather sets in? Because collagen and elastin supplementation works gradually by stimulating the body's own protein production, starting 6 to 8 weeks before the harshest seasonal conditions arrive allows time for meaningful results to develop. For most people in North America, beginning a skin supplement routine in late summer or early fall provides the lead time needed for skin to be at its most resilient when cold, dry conditions peak in late fall and winter. Can internal skin supplements replace a good topical skincare routine in fall? Internal supplements and topical skincare products address skin health through different mechanisms and work best when used together rather than as substitutes for each other. Topical products work primarily on the outer layers of skin to provide immediate moisture and protection. Internal supplements like collagen and elastin peptides work at a structural level to support the deeper dermal layers over time. The most effective fall skin prep strategy combines both approaches for comprehensive coverage inside and out.

Frequently Asked Questions
How long does it take to see results from collagen supplements
How long does it take to see results from collagen supplements
It usually takes 8 to 12 weeks of consistent daily use to see visible results from collagen supplements. Collagen works at the cellular level, so the benefits build gradually rather than overnight. Many people notice smoother, more hydrated skin first, often around the 4 week mark, while changes in elasticity, hair, nails, and joint comfort tend to follow. The key is consistency, so a daily scoop is the simplest way to give your body the collagen it's missing.
What is elastin and how is it different from collagen?
What is elastin and how is it different from collagen?
Elastin is a stretchy structural protein found in your skin and connective tissue that helps them snap back into shape after stretching. It works hand in hand with collagen, but the two play different roles: collagen is the framework that gives skin its strength and firmness, while elastin provides the elasticity and bounce that let it recoil. In short, collagen holds things together and elastin helps it spring back. Both rely on the amino acids and nutrients your body draws from your diet, which is why supporting them from the inside makes a difference.
