Vitamin Injections

Energize. Nourish. Thrive.

Vitamin Injections in Chicago, IL

No matter how well we eat or how many supplements we take, the body does not always absorb nutrients as efficiently as it could. Vitamin injections bypass the digestive system entirely, delivering key vitamins and minerals directly into the bloodstream for immediate, full-dose availability. At Therahaus Wellness Medspa in South Loop, Chicago, our vitamin injections are a quick, effective way to support energy, metabolism, immune function, and skin health as part of your overall wellness routine.

Vitamin injections are a simple, minimally invasive treatment that can be incorporated into your regular visit or scheduled as a standalone appointment. We offer Vitamin B12 for energy and neurological support, and Vitamin D for immune function, mood, and bone health. The injections are administered quickly, typically in under five minutes, and the effects are often noticeable within hours to days. They are a popular add-on for patients seeking a comprehensive approach to their health and wellness at our medspa.

The Treatment Process

How Vitamin Injections Work

When vitamins are taken orally, they must pass through the digestive tract before reaching the bloodstream, and a significant portion of the dose is lost or broken down before it can be utilized by the body. Vitamin injections deliver nutrients directly into the muscle or subcutaneous tissue, allowing for absorption rates of close to 100 percent compared to the partial absorption of oral supplements. This means the body receives the full therapeutic dose and can put it to use quickly. Depending on the vitamin and your individual health status, you may feel results within hours, particularly with B12 injections, which many patients describe as a notable increase in energy and mental clarity.

Step 1: Consultation

Your provider will discuss your wellness goals, dietary habits, and any symptoms you are experiencing to determine which vitamin injection or combination is most appropriate for your needs.

Step 2: Preparation

The injection site, typically the upper arm or gluteal area, is cleansed and prepared. The dose is drawn from a sterile vial and confirmed by your provider.

Step 3: Injection

The vitamin is administered as an intramuscular or subcutaneous injection. The process takes under five minutes and is well-tolerated by most patients.

Step 4: Results & Frequency

Many patients feel an initial boost in energy or wellness within hours to days. For sustained benefits, vitamin injections are typically recommended on a weekly or monthly schedule depending on your goals and deficiency levels.

Is This Treatment Right for You?

Who Benefits Most from Vitamin Injections

Vitamin injections are appropriate for adults who want to supplement their nutritional intake more effectively than oral supplements allow. They are particularly beneficial for those with known deficiencies, those following restrictive diets, or anyone looking for a convenient, effective wellness boost.

Ideal for patients who:

  • Experience persistent fatigue, brain fog, or low energy that does not improve with lifestyle changes alone
  • Follow a vegetarian or vegan diet and may be at risk for B12 or other nutrient deficiencies
  • Want to support skin, hair, and nail health from the inside out with biotin or other targeted nutrients
  • Are looking for a quick, effective wellness addition to their medspa visit or regular self-care routine

Vitamin Injection Aftercare: What to Know

You may notice mild soreness, redness, or a small lump at the injection site for a day or two following your appointment, all of which are normal and temporary. Most patients experience no disruption to their daily routine whatsoever. For the best results, vitamin injections should be incorporated into a consistent wellness routine and complemented by a balanced diet and adequate hydration.

Continue your regular diet and supplementation routine as recommended by your provider.
Note any changes in energy, mood, or well-being in the days following your injection to share with your provider.
Schedule regular follow-up injections at the frequency your provider recommends for sustained benefits.
Don'ts
Do not rub or massage the injection site aggressively in the hours immediately following your appointment.
Avoid strenuous exercise immediately after your injection if the site feels sore or tender.
Do not use vitamin injections as a replacement for a balanced diet or comprehensive wellness plan.
Avoid alcohol on the day of your injection to ensure your body can absorb and utilize the nutrients effectively.

Dina Andriopolous

What I loved most about Therahaus was that it had such a “family” atmosphere and it was very warm environment. I thought the services were very fairly priced (I received the Hydrafacial), and the location was more than convenient. It’s right off Lake Shore Drive and walkable to Ricobene’s! (IYKYK). Taking the wife next time so she can experience what I did. Will be back no doubt.

Ryne Haberkorn

I was nervous going into my first laser treatment, and the staff immediately made me feel comfortable. They were warm, patient, and explained everything so thoroughly. Definitely a one stop shop as they have all the newest treatments etc. Huge shoutout to Angie! She’s truly the best and made the entire experience so easy. They even offered snacks and a drink… honestly the relaxing day I didn’t know I needed. I’ll 100% be returning.

Kylie Apple

Had an amazing experience with the Therahus team! It was the first time I had IV therapy and can't reccomend it enough. Just what I needed post Bears 2026 season heartbreak :( Also, tried the hydrafacial - did not realize how much I needed it with the winter season. CAN NOT speak highly enoughabout the team. Everyone took great care of me - making me feel comfortable despite it being my first med spa experience. In addition, they were all so knowledgable about all the treatments and this is coming from a med student who just finished his skin block ;) will definitely be visiting in the near future to keep my skin glowing during this winter season!

Joseph Chavez

I had the best and most tailored experience EVER at Therahaus. I got the hydrafacial, IV drip, and lymphatic drainage massage, and it was the most perfect experience ever. Dr. Beltsos made me feel so comfortable and empowered, and I left glowing. I ended up getting the facial membership because it's such a bang for your buck, and I'm so excited to maintain this GLOW. Thank you Dr. Beltsos and team!!! I'm recommending to everyone!!!

Elaine Yoon

I don't have a single negative thing to say about Therahaus. I mean just wow! I haven’t been to this med spa before, so I was a little nervous about what to expect, but Dr. Beltsos and the entire staff were extremely friendly and knowledgeable and immediately put me at ease. They took the time to explain the procedures, the tools and machines they will use and how they work to the care routine afterwards, which made me feel very comfortable. The results were amazing. The location was also very convenient and easy to get to and lots of parking nearby, and the services were very reasonably priced. I’ll definitely be coming back and would highly recommend them.

You feel like you are in capable hands, with practitioners who know what they are doing and take pride in doing it well. Everything from scheduling to follow-up was smooth and well organized.

Demetrius Beasley

I’m genuinely blown away by this place. The fact that it’s owned and actively run by an MD already sets it apart from so many med spas where the physician isn’t closely involved. Dr. Beltsos was incredibly thorough, walking me through every step before and during my BBL and Halo treatments. I felt completely supported the whole way. And Justin, the manager, wasn’t just in the background, he was knowledgeable, engaged, and truly invested in my experience. Top-tier care from start to finish.
