Sunshine is not a supplement plan. Why most of my patients still test below the range I want.

Miami has no shortage of sun, yet most new patients test below the vitamin D range I consider optimal. Indoor work, sunscreen and time of year all add up — and D acts more like a hormone than a vitamin, touching immune function and bone health.
Test, then supplement
I never guess at vitamin D. A simple blood test sets the baseline, and we retest after twelve weeks. The goal is a documented level, not a bigger number on a bottle.
Why K2 rides along
Vitamin D helps you absorb calcium; K2 (MK-7) helps direct it toward bone rather than soft tissue. Pairing them is a small design decision that reflects how these nutrients actually work together.*
Sunshine is a variable. Your blood level is a fact.
Common questions
Short answers to what patients ask most often.
Can you be low in vitamin D in a sunny city?
Yes. Indoor work, sunscreen and season add up, and most new patients in Miami still test below the range considered optimal.
Should I test vitamin D before supplementing?
Yes. A simple blood test sets the baseline and a retest after about twelve weeks confirms the dose. The goal is a documented level, not a bigger number on a label.
Why are vitamin D and K2 taken together?
Vitamin D helps you absorb calcium and K2 as MK-7 helps direct that calcium toward bone rather than soft tissue. These statements have not been evaluated by the Food and Drug Administration.

I am incredibly grateful for the care, guidance and expertise from Dr. Elizabeth Janet Isalguez and her team at Oraganic Well especially Yasmine.
Although Dr. Isalguez is not physically located near me at this time, distance is not a barrier to the exceptional support and attention she provides. I came to Dr. Isalguez with multiple health challenges, feeling frustrated, sick, and uncertain about my future health.
From the very beginning, Dr. Isalguez and her team took the time to listen, understand the bigger picture, and most importantly create a personalized approach to my healing.
What sets Organic Well & Dr. Isalguez apart is their genuine compassion, knowledge, and commitment to addressing the root causes of illness rather than simply managing symptoms.

Trust is everything when it comes to healthcare and I trust Dr. Isalzguez completely.

From moving around the country over the past decade, I've had three functional medicine doctors. Elizabeth is the most personable of the three, and she is also very knowledgeable. The tests she uses are the best available and her use of Fullscript for supplements makes wellness a breeze.

Thank God for Dr. Isalguez! I did a telehealth with her the night before my microdiscectomy so I would have a doctor's approval in time for my surgery about a month ago and I count it as a miracle that she took the time to make this happen. A possible bacterial infection was found in my back when they opened me up. Dr. Gottleib, my surgeon said it looked "like a big pimple popped in there." They called it an abscess but hadn't gotten the lab results yet to determine the type of bacteria, if that's what it was. Once the operation was completed they sent my partner and I over to the ER at Doctor's Hospital where I stayed for a couple days while they took blood cultures and kept an eye on me. I was released late Friday after the operation and headed home to begin five weeks of IV antibiotics.
Luckily after the cultures came back everything was negative and I no longer needed the antibiotics.
Thank you, Dr. Isalguez, for taking your time late in the day to help me get my much-needed back surgery. I'm in much less pain now and very grateful to you.

A Truly Exceptional Doctor!
Dr. Isalguez is one of the most thorough and compassionate doctors I’ve ever had the pleasure of seeing. Unlike many past experiences, she actually makes eye contact, listens intently, and takes the time to walk through your full medical history with care and attention.
She doesn’t rush—she engages in a real conversation, explains everything in detail, and makes sure you fully understand what’s happening with your health. Her medical staff is just as incredible: warm, patient, and attentive. They made sure I felt completely comfortable, walking me through each step and answering every question I had.
Although I currently reside in New York City, I will gladly make trips to Miami to continue my care with Dr. Isalguez. She is incredibly knowledgeable, thoughtful, and dedicated to her patients. I left her office feeling informed, reassured, and truly cared for.
Highly recommend!
