IM Vitamin Injections · Fleming Island, FL
Vitamin and nutrient support, delivered by injection
B12, D3, glutathione, and more. Intramuscular vitamin and nutrient shots for energy, immunity, and recovery, administered by our clinical team as a layer within your wider wellness plan, never a stand-alone fix.
Written by the Well Labs+ editorial team · Last updated July 2026
Category Overview
Nutrient support, delivered directly
Some vitamins and nutrients are better delivered by injection than by supplement, bypassing digestion so your body can put them to use directly. Our clinical team administers each shot as wellness support, matched to what you are trying to support, whether that is energy, immunity, or recovery.
These shots are not a treatment for a specific disease and not a weight-loss program. If your goal is sustainable, physician-supervised weight loss, our Medical Weight Loss program is the right place to start, and vitamin support can be layered in from there as part of our complete wellness & body offerings.

Explore IV Therapy & Wellness DripsThe Shots We Offer
Six intramuscular shots, matched to your goal
Each shot supports a different wellness goal. Your provider recommends the one, or the combination, that fits what you need at your visit.
Vitamin B12
A classic intramuscular B12 shot to support energy and metabolism. It's a common fit for anyone feeling run down or following a plant-based diet where B12 can run low.
Vitamin D3
Direct D3 support for immune and bone health, for the many patients who test lower than expected despite the Florida sun.
Glutathione
An antioxidant shot to support cellular health and skin brightness, as part of a broader wellness plan rather than a treatment on its own.
Amino Blend
An amino-acid injection to support recovery and lean muscle maintenance for active patients and anyone training regularly.
Tri-Immune Boost
A seasonal immune-support blend for patients who want extra support heading into travel, school schedules, or cold and flu season.
Rise & Shine
An energizing B-vitamin and amino blend positioned as a morning pick-me-up. Quick support for a demanding week, not a stimulant substitute.
In Expert Hands
Administered by your clinical care team, every visit
A quick shot still deserves clinical oversight. Every injection at Pura Vida is administered by our clinical team, led by Kara Wilfong, DNP, APRN, FNP-C, who reviews your history and matches the shot to your goal before you’re seen.
Vitamin support is part of a bigger picture, part of the full wellness & body program built around you.
Realistic Results
Vitamin B12 shot results: what to realistically expect
People search for "B12 shots before and after," so here is the honest version. A vitamin B12 shot works from the inside to support energy, recovery, and immune health. There is no visible cosmetic before-and-after, and what patients notice is how they feel over the following days, not a change in a photo.
The first few days
Many patients feel a lift in energy, focus, or recovery within a day or two of a B12 shot, especially if they were running low to begin with.
With a regular cadence
Used every one to four weeks as part of a wider wellness plan, B12 supports steadier energy and recovery over time. Your provider sets the cadence around how you actually feel.
Why there's no before-and-after photo
B12 is internal nutrient support, not a cosmetic treatment, so a before-and-after image would misrepresent what it does. If a visible change is your goal, your provider will point you to the treatment that delivers it.
Fleming Island · Northeast Florida
Energy support for an active Fleming Island
Between the Florida heat, active weekends on the river, and demanding schedules, Fleming Island and Clay County patients often come to us running on empty. A quick, provider-administered vitamin shot fits an active, on-the-go lifestyle, whether you are recovering from a workout, heading into a busy season, or simply want an energy boost that a coffee can’t match.
Northeast Florida’s UV index climbs to extreme from spring through late summer, and sun exposure drives much of the collagen loss and visible aging we treat, so care here is as much about prevention as it is about correction.
The practice Fleming Island trusts for medical wellness. Voted the area’s best medspa six years running, cared for from our Medical Spa on Island Lane.

Frequently Asked Questions
IM Vitamin Injections Questions, Answered
What's the difference between a vitamin B12 shot and an IV drip?
A vitamin B12 shot is a single, targeted nutrient delivered by a quick intramuscular injection, while an IV drip infuses a broader blend of vitamins, minerals, and fluids directly into your bloodstream over a longer visit. An IM shot bypasses digestion just like an IV does, so it is a faster and lower-cost way to support one specific goal, like energy or immune support, while our IV Therapy & Wellness Drips program is the better fit for a fuller hydration and nutrient reset in one sitting. Your provider can help you decide which one matches what you need that day.
Will a vitamin injection help me lose weight?
No, vitamin injections are not a weight-loss treatment, and we will not frame them that way. They support energy, recovery, and immune health as part of a broader wellness plan. If sustainable, physician-supervised weight loss is your goal, our Medical Weight Loss program is the right place to start, and vitamin support can be layered into that plan where appropriate.
How often should you get a vitamin B12 shot?
Most patients get a vitamin B12 shot every one to four weeks, though the right cadence depends on the shot and your goals. Some come in weekly for a season to rebuild energy, while others use a single shot occasionally alongside another wellness visit. Your provider will recommend a schedule based on what you are trying to support.
Are there side effects from IM vitamin injections?
Most patients notice only brief soreness at the injection site, and true allergic reactions are uncommon. We review your allergy history and current medications before recommending a specific shot, and our clinical team monitors you at every visit.
Who administers vitamin injections at Pura Vida?
Every injection at Pura Vida is given by our clinical team, led by Kara Wilfong, DNP, APRN, FNP-C, with health content on this site medically reviewed by our Medical Director. Pura Vida has been voted the area's best medspa six years running, and that same clinical team reviews your health history and matches the shot to your goal before you're ever seen.
Where can I get vitamin B12 shots near Fleming Island?
Pura Vida offers vitamin B12 shots and our full line of IM injections at our Medical Spa on Island Lane in Fleming Island, FL, and we care for patients from Fleming Island, Orange Park, Middleburg, Green Cove Springs, and the greater Jacksonville area in Clay County. A quick, provider-administered shot fits easily into an active Fleming Island lifestyle, whether you're recovering from a workout on the river or squeezing in energy support during a busy week.
Are there before-and-after results for vitamin B12 shots?
There is no visible cosmetic before-and-after for a vitamin B12 shot, and we will not market one. B12 and our other IM injections support energy, recovery, and immune health from the inside, so what patients notice is how they feel rather than a change in a photo. If your goal is a visible cosmetic result, your provider can point you toward the treatment that actually delivers it.
