Vitamin D Injections

Vitamin D helps regulate the amount of calcium and phosphate in the body. These nutrients are needed to keep bones, teeth, and muscles healthy.

Why do people take Vitamin D injections? How does it help you?

People generally supplement with Vitamin D when yearly physical lab work includes a Vitamin D level blood check and they find out that they are low. Otherwise, it’s hard to even know. Vitamin D helps regulate the amount of calcium and phosphate in the body. These nutrients are needed to keep bones, teeth, and muscles healthy. A lack of Vitamin D can lead to bone deformities and bone pain. Increasingly, research is revealing the importance of vitamin D in protecting against a host of health problems such as depression, the flu or illness, multiple sclerosis, heart disease, and cancer. It also may help with weight loss. Most recently vitamin D is being studied and indicated for protection with COVID-19.

  • FAQs

Who has Vitamin D deficiencies and why?

Being indoors and isolated by COVID hasn't helped, but our nation is and was already struggling with Vitamin D deficiency issues prior to this past year. The vast majority of Americans feel that they should have normal Vitamin D due to sun exposure and dietary intake, yet they still come back as having very low levels. Without supplementation, the odds are just not in your favor. Vitamin D is made by the body when the skin is exposed to sunlight. Being indoors and isolated due to COVID-19 has placed our nation at increased risk of having low vitamin d levels. Vitamin D is extracted from the blood by fat cells, altering its release into the circulation. People with a body mass index of 30 or greater often have low blood levels of Vitamin D. Also, sunscreen, protective clothing, dark skin, and age may prevent getting enough vitamin D from the sun. 

What are the possible side effects of taking supplemental Vitamin D?

The most common reason people experience severe side effects associated with vitamin D is taking excessive amounts. This causes an increase in blood calcium. Some early symptoms that someone is experiencing Vitamin D toxicity include nausea, vomiting, diarrhea, constipation, weakness, excessive thirst, an altered level of consciousness, high blood pressure, and kidney failure or hearing loss may also develop. This is rare, but Vitamin D toxicity can be dangerous. If you experience Vitamin D toxicity, it may take a few months for the issue to resolve because the excess vitamin D is stored in fat. Other possible side effects to be aware of include fatigue and sleepiness, headaches, loss of appetite, a dry mouth, and a metallic taste in the mouth. It’s important to monitor blood Vitamin D levels when using supplemental Vitamin D.

What is the dosage of Vitamin D that you supply?

Vitamin D3 (Cholecalciferol) Intramuscular Injection (5cc) 500,000IU In the vial. I like dosing 1/2cc (50,000IU) once a month. This is conservative but more than adequate therapy for most people. I see no need to blast your vitamin D levels higher than they need to be. The key with most all things in life is moderation. We can discuss alternative dosing individually. This regimen will treat you for a year as it supplies you with one injection once a month for 10 months. I advise (but don't require) you to recheck your vitamin D level after starting supplementation.

What Clients Say

“I went from 304 pounds to 260 pounds since April 15th, 2018. It is now December. Hope to lose at least another 60 pounds or more. Works great for me!”


“I've been on it for two full months.I started with 5mg for a month then 10mg for the second month. I'm starting my 2nd 10mg pen and my third month. I've experienced some loose stools during the first two weeks then back to normal. I've had no other adverse effects and my sugar has gone down from the 230 range to the 150 range and hopefully still dropping. My weight has gone from 365 to 340. I noticed that I don't want to eat as much, the effect is very subtle but I've learned to recognize it and I just push away from the table. So far everything's thumbs up.”


“I only had one thing that I wasn't pleased with and that was nausea, it was very intense for about 2 weeks then it subsided. It was a great weight loss. I find the advantages of the drug well worth the side effects. I feel that I have more control over my blood sugar than I have in ten years!! I wish I was aware of it sooner. Just not knowing what my high readings have done to some of my vital organs is scary. I feel now that I'm on the right track and I finally have peace of mind about my health.”


“I’ve been on it for 1 week and have lost 4LBS. no sickness, sugars are 1/2 what they were. injections hurt far less than lancets! miracle drug for my type 2. appetite is 1/4th what used to be. I'm looking forward to my next A1c.”
