Living in Florida can make vitamin D deficiency seem unlikely. In my practice, healthy, active patients are sometimes surprised to learn that their levels are low. Sunshine alone does not tell us whether someone has enough vitamin D.
Before cosmetic surgery, nutrition deserves attention alongside the procedure itself. Vitamin D deficiency can require treatment, and vitamin K2 is attracting research interest. The goal is to understand what your body needs and make a plan before surgery.
Why vitamin D can be low in Florida
Vitamin D status reflects more than the weather. Limited time outdoors, low dietary intake and problems absorbing nutrients can contribute. Older age, darker skin and obesity can also affect vitamin D levels. A Florida address cannot rule out a deficiency. [1]
Sunscreen deserves a careful explanation. The 2025 Sun-D randomized trial found that regular SPF 50+ use produced modestly lower vitamin D levels than discretionary sunscreen use. That supports considering vitamin D intake in people who consistently protect their skin. It does not mean every sunscreen user becomes deficient, and the study was conducted in Australia rather than Florida. [2]
Keep protecting your skin. Food and appropriate supplementation offer ways to address vitamin D needs without deliberately increasing ultraviolet exposure. [1] If your food intake has fallen substantially during weight loss, mention that during your preoperative assessment so your overall nutrition can be reviewed.
What vitamin D and K2 do
Vitamin D helps the body absorb calcium and supports normal bone, muscle and immune function. Severe deficiency can cause bone pain and muscle weakness. [1] D3, or cholecalciferol, is a common form of vitamin D used in supplements. [9]
Vitamin K is a family of nutrients that includes K1 and K2. Vitamin K helps activate proteins involved in blood clotting and bone metabolism, including osteocalcin. Another vitamin K-dependent protein, matrix Gla protein, is being studied for its role in limiting abnormal calcification. MK-7 is one form of K2 used in supplements. [3]
Those related functions are the rationale for combining D3 and K2. They do not establish that everyone taking vitamin D needs an additional K2 supplement. [3]
What newer K2 research shows
A 2026 randomized trial in JAMA Cardiology studied 180 adults with symptomatic coronary artery disease. Over two years, MK-7 slowed the progression of coronary calcium on CT compared with placebo. This is an encouraging finding, but it did not establish fewer heart attacks, longer life or better healing after cosmetic surgery. The clinical meaning of the imaging change remains uncertain. [4]
Results also differ across conditions. A separate 2022 randomized trial found that K2 plus vitamin D did not slow aortic valve calcification in older men with existing valve calcium. [5] The evidence is still developing, and these results do not show that taking K2 protects everyone against harmful calcium deposits.
What this means for surgical recovery
Surgery places demands on the body, which is why preparation includes reviewing nutrition and any known deficiencies. Some research suggests vitamin D treatment may help selected surgical patients. For example, a 2024 study of hip and knee replacement patients found fewer superficial wound infections in the supplemented group. [6]
However, that study was not randomized, the comparison group had unknown vitamin D levels, and deep prosthetic joint infection rates were not significantly different. It cannot establish that the same approach improves facelift scars, reduces swelling or speeds recovery after body contouring. [6]
My practical message is to address a documented deficiency as part of your preparation. If your vitamin D level is already adequate, extra supplementation has not been established as a way to improve your cosmetic result. Your surgical team can help decide what needs attention before your procedure.
Who should consider testing
The usual test is 25-hydroxyvitamin D, often written as 25(OH)D. Testing may be useful when symptoms, a bone disorder, malabsorption or other clinical concerns make deficiency more likely. A clinician can also use it to monitor treatment when appropriate. [7]
Routine screening is not recommended for every otherwise healthy adult. The Endocrine Society’s 2024 prevention guideline does not establish a universal blood-level target for improved health outcomes. An individual preoperative assessment should explain why testing would be useful for that patient. [8]
Understanding your vitamin D result
Thresholds differ between organizations and laboratories. The National Academies framework summarized by NIH identifies levels below 12 ng/mL as carrying deficiency risk, 12 to below 20 ng/mL as potentially inadequate, and 20 ng/mL or higher as adequate for most people. These are general benchmarks, not a surgical clearance rule. [9]
There is no established universal target of 40–60 ng/mL for better cosmetic surgery healing. NIH also notes potential adverse effects above 50 ng/mL. A treatment target should reflect your clinical situation; a higher number is not automatically a better result. [8, 9]
Choosing a supplement and dose
Treatment should account for your test result, diet, medical conditions and current supplements. The usual adult upper intake limit for vitamin D is 4,000 IU daily from all sources. Clinicians sometimes prescribe more to treat deficiency, with appropriate monitoring. A 5,000 IU daily regimen needs clinical guidance even though it is sold over the counter. K2 is not an antidote to vitamin D toxicity. [9]
K2 also needs an individual decision. If you take warfarin or another vitamin K antagonist, do not start, stop or change K2 without the clinician managing that medication. Changes in vitamin K intake can change its effect. [3]
Give your surgeon and anesthesia team the names and doses of every supplement you take. Ask for instructions about continuing or holding each product around surgery. If you have a known deficiency, discuss it early enough to allow treatment and any follow-up testing your clinician recommends. There is no single supplementation timetable that guarantees readiness for surgery.
Frequently asked questions
Can I have low vitamin D even if I live in Florida?
Yes. Location alone does not establish your vitamin D status. Your diet, medical history and other individual factors matter. [1]
Do I have to take K2 with D3?
An added K2 supplement is not established as necessary for everyone taking D3. The choice should reflect your circumstances, especially your medications. [3]
Will D3 and K2 make my scars heal better?
The research discussed here does not establish that this combination improves cosmetic surgery scars. If you have a deficiency, your clinician can help you address it as part of your preparation. [4, 5, 6]
Should I begin taking supplements just before surgery?
Check with your surgical team before adding a product. Bring recent lab results and your supplement list to the preoperative visit so any treatment can fit your care plan.
What if my vitamin D level is already adequate?
Discuss whether your current intake meets your needs. There is no established reason to push an adequate level into a higher range solely to improve cosmetic surgery recovery. [8]
