Does calcium help with dry skin during perimenopause?

Calcium has a genuine biological role in skin, but its connection to the dryness experienced during perimenopause is indirect and the evidence for supplementation is very thin. Calcium is involved in keratinocyte differentiation, which is the process by which skin cells mature and form the protective outer layer of the skin barrier. When calcium gradients in the epidermis are disrupted, skin barrier function can suffer, leading to increased water loss through the skin. However, perimenopausal dry skin is driven primarily by declining estrogen, not calcium deficiency, and supplementing calcium is unlikely to be a meaningful solution unless you are genuinely deficient.

Looking at the research, there are no well-designed clinical trials specifically testing calcium supplementation for dry skin in perimenopausal women. Some basic science and dermatology research confirms that calcium gradients in the skin are essential for barrier integrity, and that disrupting these gradients (through experimental means) impairs barrier function. A few studies have noted that topical calcium-containing formulations can support skin barrier repair after damage. From an oral supplementation standpoint, the evidence is essentially absent for improving skin hydration or dryness. What does appear in the literature is the established connection between vitamin D and skin health, and since vitamin D is required for calcium absorption and the two work closely together, vitamin D is the more evidence-supported nutrient for skin in this population.

Estrogen does the heavy lifting for skin moisture in the premenopausal years. Estrogen stimulates production of collagen, hyaluronic acid, and sebum. It supports the skin's ability to retain water. When estrogen falls and fluctuates during perimenopause, skin can become thinner, drier, and less elastic relatively quickly. Some women notice these changes within one to two years of perimenopause onset. The transepidermal water loss that characterizes perimenopausal dry skin is primarily driven by this estrogen withdrawal rather than by any nutritional deficiency in most women. Addressing the skin barrier through topical means, including ceramide-containing moisturizers, hyaluronic acid, and occlusives like petrolatum, is more directly effective than trying to compensate through calcium supplementation.

If you are supplementing calcium for bone health, which is a well-supported reason to do so during perimenopause, maintaining adequate intake is sensible. Standard recommendations are approximately 1,000 to 1,200 mg per day from food and supplements combined for women in this age range. Talk to your healthcare provider about the right approach for your situation. Calcium citrate is better absorbed than calcium carbonate and is gentler on the digestive system. Food sources including dairy, fortified plant milks, sardines, edamame, and leafy greens are preferable to high-dose supplements for most of your calcium needs. Getting vitamin D tested and corrected is likely to have more impact on both skin and overall perimenopause health than additional calcium supplementation beyond what you need for bone support.

Be aware of the upper safe limit for total calcium from all sources, which is approximately 2,500 mg per day. There is an ongoing cardiovascular debate around high-dose calcium supplements in postmenopausal women, with some studies suggesting an increased risk of cardiovascular events at very high supplement doses. Prioritizing food sources reduces this concern. Calcium and iron compete for absorption, so space these supplements at least two hours apart if you take both. If you take prescription medications, including levothyroxine or certain antibiotics, check timing with your provider since calcium can interfere with absorption.

For dry skin specifically, the most evidence-supported approach is a combination of topical hydration (apply moisturizer within three minutes of bathing to lock in moisture), staying well hydrated, maintaining adequate omega-3 fatty acid intake (which supports skin lipid production), and considering whether your vitamin D level has been checked. Oral collagen peptides have more direct skin evidence in perimenopausal women than calcium supplementation does. These approaches target the actual drivers of perimenopausal skin dryness more directly than calcium.

See a doctor if your skin changes are severe and rapid, if you have developed new rashes, significant itching without an obvious cause, or if your skin feels numb or painful. Severe skin dryness that does not respond to topical moisturization may warrant evaluation for thyroid dysfunction, which is more common during perimenopause and can cause significant skin changes. Eczema and psoriasis can also flare during perimenopause due to immune changes and should be evaluated if present.

If you are tracking skin quality, note it daily alongside your cycle phase and hydration habits. You may find that skin feels drier at certain hormonal moments in your cycle. The PeriPlan app (https://apps.apple.com/app/periplan/id6740066498) lets you log skin and other symptoms alongside cycle phase, which can help you identify patterns and discuss them more clearly with your provider or dermatologist.
