What Are B12 + Vitamin Injections?
B12 and vitamin injections deliver essential nutrients straight into your muscle for fast absorption. Unlike oral vitamins, which lose a lot in digestion, injectable nutrients bypass the gut and go to work quickly.
At Mint, our vitamin injections include B12 (the energy and metabolism workhorse) and an immune-boost blend designed to support your body during stress, travel, illness recovery, and high-output seasons of life.
You're Doing Everything Right and Still Running on Empty
You sleep okay. You eat well. You take the multivitamin. You still feel tired by 2 PM. Your workouts feel harder than they should. You catch every cold that walks through the house. Your hair and skin look duller than they used to.
A lot of "I'm just tired" is actually a vitamin deficiency nobody has measured. B12 specifically is one of the most underdiagnosed deficiencies in adults. The good news: this is one of the easiest things to fix.

Who B12 + Vitamin Injections Are For
Quick vitamin injections at Mint are for:
Adults dealing with low energy or chronic fatigue
Athletes and active people who train hard
Anyone recovering from illness or surgery
People with restrictive diets (vegan, vegetarian, low-protein)
Anyone over 40 (B12 absorption declines with age)
Patients on metformin, acid reducers, or certain other medications that affect B12 absorption
Anyone wanting an immune boost during cold and flu season, travel, or high-stress weeks
If you've ever wondered whether your "normal tired" is normal, a B12 panel is worth running.

Real Quality, Not the Cheapest Stuff in the Cabinet
Mint sources B12 and immune-boost blends through trusted compounding pharmacies and uses methylcobalamin (the active form of B12) rather than cyanocobalamin, which your body has to convert. The difference shows up in how you feel.
Mint is led by Dr. Sanjay Sundar, MD (Medical Director) and Rachel Sundar, RN (Founder), with Nurse Practitioner Nikki Goff, DNP, on the clinical team. Every vitamin protocol at Mint is provider-cleared, and the same team handles hormones, peptides, and weight loss if the fatigue you're chasing turns out to be bigger than a B12 deficiency.

More About Vitamin Injections at Mint
Mint Aesthetics + Wellness offers quick B12 injections and immune-boost vitamin injections at our Bettendorf, Iowa clinic. Vitamin injections at Mint are designed for fast in-and-out visits and deliver essential nutrients directly into the muscle for maximum absorption, bypassing the digestive system entirely.

B12 (methylcobalamin) is one of the most commonly under-diagnosed nutritional deficiencies in adults and is closely tied to energy, metabolism, cognitive function, mood, and red blood cell production. Adults over 40, patients on metformin or acid-reducing medications, vegans, vegetarians, athletes, and people recovering from illness or surgery often benefit from regular B12 injections. Mint uses methylcobalamin rather than cyanocobalamin, because the active form is more bioavailable and does not require enzymatic conversion in the liver before the body can use it.
Immune-boost injections at Mint are a provider-formulated blend designed to support the immune system during cold and flu season, travel, recovery from illness, or sustained periods of high physical or emotional stress. Pricing for B12 and immune-boost injections runs $20 to $40 per visit, with complimentary B12 injections included for TRT and BHRT members. Patients cleared by a provider can purchase a vial for at-home use, which lowers the per-dose cost for those who use injections regularly.
For patients dealing with chronic fatigue, the Mint clinical team may recommend a full Wellness Panel to investigate hormone, thyroid, or iron contributors to low energy. Vitamin injections are often paired with hormone replacement therapy, peptide therapy, or medical weight loss programs for additional support.
Mint serves patients across the Quad Cities, including Bettendorf, Davenport, Moline, Rock Island, East Moline, Eldridge, LeClaire, Walcott, Silvis, Colona, Milan, Muscatine, Clinton, Iowa City, Aledo, Cambridge, Kewanee, Geneseo, and surrounding communities. The clinical team is led by Dr. Sanjay Sundar, MD (Medical Director) and Rachel Sundar, RN (Founder), with Nurse Practitioner Nikki Goff, DNP, and aesthetician Lori Caruso. In-person visits are required for vitamin injections.
