Founder of Health & Vitality Center

As the founder and medical director of Health & Vitality Center, Dr. Lalezar created a clinic designed to move beyond reactive care. The practice was built around comprehensive diagnostics, personalized protocols, and long-term health optimization.

Her patients often come to her after feeling unheard or frustrated by conventional approaches that offered limited answers. Through in-depth evaluations — including advanced laboratory testing of blood, urine, saliva, and stool — she identifies hidden imbalances that contribute to fatigue, hormone dysfunction, brain fog, metabolic disorders, immune dysregulation, and chronic inflammatory conditions.

Hormone Optimization

Hormones regulate metabolism, mood, sleep, cognition, and longevity. This pillar focuses on restoring balance in estrogen, progesterone, testosterone, thyroid hormones, and adrenal function to support vitality and prevent age-related decline.

A Root-Cause Philosophy

Dr. Lalezar believes that chronic disease rarely develops overnight. Instead, it evolves gradually as inflammation, hormonal imbalance, nutrient depletion, toxin exposure, and stress accumulate over time. Rather than focusing on isolated symptoms, she evaluates how the gut, liver, immune system, endocrine system, and brain communicate and interact. By restoring balance at the systems level, patients often experience improvements that extend beyond their primary complaint.

Her approach is methodical and personalized. Each care plan is developed based on laboratory findings, patient history, and individual goals. Treatment may include nutrition therapy, lifestyle modification, IV therapies, peptide protocols, detoxification, and hormone optimization — always tailored to the patient.

"Most functional medicine practitioners aren't even addressing the 'remove' part of the protocol. They're throwing supplements and IVs at patients, but not actually moving toxins out."

— Dr. Shiva Lalezar

Testimonials

“I highly recommend Dr Lalezar.”

I went to Dr Lalezar frustrated that after having seen 4 specialists, 3 years of aggravation, having gained more than 30 lbs, no one could figure out what was wrong with my thyroid.

Well she did in the first 10 min I met her. I also found out that the level of mercury in my body was thru the roof. She fixed that too with her chelation treatment and only in a few sessions.

Not only she is the most pleasant doctor you will meet, but also she is one of the brightest. She thinks in 3 dimensions and combines her knowledge of western medicine with osteopathy beautifully. She is extremely competent.

Her office staff are so kind, considerate, and patient orientated. Dr. Lalezar has spent so much energy, turning her office and treatment center into a beautiful, calm, zen spot, following Feng shui elements. You will never feel like you are in a doctor’s office.

I have come across people who have come to her office as far as Barstow. I highly recommend Dr Lalezar.

“I feel better than I have felt in years”

“I feel better than I have felt in years thanks to Dr. Lalezar. Seriously, I had been to other doctors and when they asked how I felt and I said “meh” they just shrugged it off. It turns out I was suffering from extreme mercury toxicity.Thank goodness Dr. Lalezar knew what tests to give me. She also has prescribed hormones and various minerals and micronutrients to get me feeling better than ever. Those, along with IV chelations have made incredible transformations in my health.

Three friends in the past week have told me how good I look. I also brought my 16-year-old daughter to see her for a full exam and Dr. Lalezar has been compassionate, thoughtful, and nurturing to us both.”

“Dr. Lalezar cured me and GAVE ME MY LIFE BACK.”

Starting in February 2018 I started to develop a mysterious, severe face rash that conventional doctors could not determine the cause. By March, it progressed and it was very painful…it felt like my face was on fire and weeping blisters developed on my face. It was horrible. I didn’t want to go anywhere. Doctors tried me on all sorts of medications. I also switched out all my makeup and skin care products. Nothing cured it. Additionally, the doctors would prescribe Prednisone, which helped, but as soon as I tapered off, the painful rash would reappear…and worse each time! The conventional doctor finally told me he thought I was developing psoriasis. I refused to believe that. I intuitively knew I was reacting to something.

I spent countless hours researching possible causes on the Internet. I thought maybe I developed an allergy to a certain food. So I went on an elimination diet and for several weeks only ate fruits, vegetables and salmon. I also got allergy tested for cat dander and goose feathers as I theorized maybe I developed an allergy to my cats or to my feather comforter. None of this helped. The burning rash and blisters continued to return.

I didn’t want to return to the conventional doctors. They were at a loss, too. I knew I had to take a different approach.

I found Dr. Lalezar’s website and resonated with what I saw. I had treated with functional medicine practitioners with great success in the past.

Dr. Lalezar cured me and GAVE ME MY LIFE BACK.

How?

Ten years ago I was diagnosed with a nickel allergy. During my Internet research, I studied nickel allergy and saw that many magnets contain nickel. In July 2017 I started wearing magnetic lashes. I thought it was pretty far-fetched that my lashes – with extremely tiny magnets – would be the cause of my face rash. Because my rash didn’t start developing until many months after I started wearing the lashes. And, even though the rash did start underneath my eyes, the rash had spread to many parts of my face, including by my ears, my forehead and underneath my chin.

Keep in mind, even when my face was at its worst, I CONTINUED TO WEAR THE LASHES. I figured because I couldn’t wear makeup, those lashes were the one element of beauty I could easily still wear.

Dr. Lalezar took ample time to meet with me and listen to my medical history. I mentioned my nickel allergy and told her about the magnetic lashes. (Although, again, I still thought it likely wasn’t the cause.)

She submitted my blood for testing and she also had me to a six-hour urine test that would test the presence of many heavy metals in my body.

In the meantime as I was awaiting results of my labs, I contacted the company where I bought the lashes from. They couldn’t help me when I called them, so I emailed the company. Nine days later they responded to me, informing me that the magnets on their lashes were indeed “black nickel coated.”

I decided to stop wearing the lashes to see what would happen. The last day I wore them was April 25, and I was in the middle of tapering off a round of Prednisone. (If the lashes were the culprit, then my nickel reaction would occur three days later per my allergy results regarding nickel 10 years ago.) My Prednisone taper ended April 26.

The rash returned; however, by April 28, the rash would have progressed to the oozing stage. It didn’t. The red, dry, itchy rash appeared in various parts all over my face, but it didn’t burn as bad and it never started oozing. It plateaued. Why didn’t it progress this time? The only thing I changed was I stopped wearing the lashes. Now I was pretty convinced the lashes were the culprit.

On April 30, I saw Dr. Lalezar because the results came in on my heavy metals testing. It revealed that I had an excessive amount of nickel in my body…more than four times the limit a human being should have in the body. It was evident that the nickel-plated magnetic lashes was the primary contributor to my face rash.

After months of obsessive research and dealing with the terrible rash, and with the help and expertise of Dr. Lalezar, I was overjoyed and eternally grateful to have finally found the cause of my ugly and painful face. Needless to say, I immediately threw the lashes away, and Dr. Lalezar started me on IV chelation therapy to expel the nickel out of my body.

A couple of weeks later (by Mother’s Day!), my face was almost fully healed. I will forever be grateful to Dr. Lalezar for helping me solve the terrible mystery of my awful face rash that was ruining my life. Since this experience, I’ve done further research on heavy metal toxicity, and it’s amazing the kinds of health problems people can suffer from due to large amounts of heavy metals in their bodies. It is a contributor to many types of ailments and illnesses. And mainstream medical providers do not address this.

Thank you from the bottom of my heart, Dr. Lalezar and team!!!

“Dr. Lalezar is wonderful at examining the whole picture”

“I am currently seeing Dr. Lalezar to get to the bottom of several issues including fatigue, hormone imbalance, high cholesterol, and mood disorder. I am trying to get off some of my medications. I am so tired of traditional doctors just giving you a pill for your symptoms.

Dr. Lalezar is wonderful at examining the whole picture: hormones, nutrition, toxicity, and the environment. I really feel that she is interested in helping me. Just for example, I changed my diet and started taking Red Yeast Rice per her advice, and my cholesterol went down 40 points in 3 months! The bio-identical hormones have also made a huge difference in my energy levels.

Functional medicine requires more involvement and responsibility from the patient too. If you want to take control of your health, I recommend Dr. Lalezar and her capable staff.”

– L. L.

“She was very professional and kind”

I went to see Dr. Lalezar for answers regarding my overall health and low immune system. After taking lots of blood samples and a urine sample and waiting for a few weeks Dr. Lalezaradeh’s office called me in to meet with the Dr who went over ALL of my test results and figured out why my immune system is down and drafted a plan to get me back on track (which worked). She was very professional and kind and her Vitamin C injection is like medical crack it will have you up and running in no time. It really works! The only down fall is that she tests for EVERYTHING and somethings are NOTcovered through insurance so make sure you have met your deductible. Oh and shout out to the staff who are very warm and welcoming.

– Keith M.

“Great experience.”
