VITAMIN INJECTIONS
B-12, B-12 Ultra, Biotin, Vitamin C, Glutathione
Our vitamin injections include B-12, B-12 Ultra, Biotin, Vitamin C, and Glutathione — each chosen for a different goal. Delivered directly into the bloodstream, they bypass the digestive system entirely, so absorption is faster and more complete than an oral supplement can offer. Depending on which you choose, injectable vitamins can support energy and metabolism, strengthen hair, skin, and nails, reinforce immune function, or provide antioxidant support. Most appointments take 10 to 15 minutes.
HOW VITAMIN INJECTIONS WORK
OUR VITAMIN INJECTIONS
Different goals call for different formulas. Here’s what each one is built to do.
The workhorse. Vitamin B-12 supports red blood cell production, nervous system function, and how efficiently your body converts food into usable energy. It’s the right starting point if you’re dealing with persistent fatigue, brain fog, or afternoon crashes — and especially relevant if you follow a plant-based diet, are over 50, or have a condition that affects absorption.
B-12 with lipotropic compounds added — nutrients that support how your liver processes and mobilizes fat. Chosen most often by patients pairing their injections with a weight management plan who want metabolic support alongside the energy benefit.
Biotin supports keratin production, the structural protein your hair and nails are built from. Patients dealing with thinning hair, brittle nails, or hair shedding after pregnancy, stress, or a significant weight change tend to see the most benefit. Results build gradually — plan on consistent injections over several months rather than a single visit.
Vitamin C does two jobs at once. It’s a cornerstone of immune function, and it’s essential to collagen synthesis — the same protein that keeps skin firm and supports wound healing. Injected, it reaches your bloodstream at a concentration the digestive system simply can’t deliver, since oral absorption drops off sharply at higher doses. A strong choice heading into a busy season, before or after travel, or alongside skin treatments where collagen support matters.
Often called the body’s master antioxidant, glutathione is produced naturally in your cells and helps neutralize free radicals while supporting the liver’s detoxification pathways. Natural levels decline with age and drop further under stress, poor sleep, and environmental exposure. Patients choose it for overall antioxidant support, general wellness, and a healthier-looking complexion. It pairs particularly well with Vitamin C, which helps regenerate glutathione once it’s been used up.

PROS:
- Immediate Results: Because the vitamins are absorbed directly into the bloodstream, results are felt quicker than oral supplements. After one session, people feel more energized and focused.
- Higher Bioavailability: The vitamins bypass the digestive system, making absorption more efficient. A high concentration of nutrients reaches the bloodstream.
- Convenience: Injections takes just 10-15 minutes administered in an in-office visit. A convenient way to get a nutrient boost for busy lifestyles.
- No Digestive Side Effects: A more comfortable alternative than oral supplements for individuals with digestive issues like IBS, crohn’s or celiac disease.
- Customizable Treatment: Injectable vitamins can be tailored to address specific health concerns — energy and metabolism, hair and nail growth, immune support, collagen production, or antioxidant and detox support.
CONS:
- Initial Cost: Injectable vitamins are more expensive upfront compared to oral supplements. But people find the convenience and quick results worth the investment.
- Repeat Sessions: To maintain the benefits, this method of vitamin intake requires regular sessions. Frequency depends on the formula and your goals — B-12 shots are typically given monthly, while others may be scheduled more or less often. Your provider will recommend a cadence at your consultation.
- Mild Discomfort: Some individuals experience redness or swelling at the injection site. This is temporary and resolves in a few days.
- Not a Substitute for a Healthy Diet: Vitamin injections are not a substitute for a healthy, balanced diet. Proper intake of vitamins and minerals through nutrition is equally important.
- Limited Long-Term Evidence: There is limited long-term research. For example, improved energy or skin health may be anecdotal and based on short-term studies.
VITAMIN SHOTS FREQUENTLY ASKED QUESTIONS
Vitamin injections raise a lot of the same questions, so we’ve answered the ones we hear most. If yours isn’t here, call us at (210) 960-5222 — we’re happy to talk it through before you book.
It depends on what you’re trying to change. B-12 is the starting point for fatigue, brain fog, and low energy. B-12 Ultra adds lipotropic support for patients pairing injections with a weight management plan. Biotin is for hair thinning and brittle nails. Vitamin C supports immune function and collagen production. Glutathione provides antioxidant and detoxification support. Many patients combine two — Vitamin C and Glutathione in particular work well together. Your provider will make a recommendation based on your health history and goals at your first visit.
Most patients feel the effects of an injection within 24 to 48 hours, with benefits lasting several weeks. Duration varies by formula and by person — how deficient you were to start, how often you come in, your overall health, and your metabolism all play a role. B-12 is commonly scheduled monthly. Biotin works cumulatively, so results build over several months of consistent treatment rather than showing up after one visit. Vitamin C and Glutathione are often scheduled more frequently during periods of high stress, travel, or illness exposure.
An intramuscular injection delivers a concentrated dose into the muscle — usually the upper arm or thigh — where it absorbs steadily into the bloodstream over the following hours. An IV infusion delivers fluids and nutrients directly into a vein for immediate circulation. Injections take 10 to 15 minutes and are the more convenient option for routine nutrient support. Infusions take longer and deliver larger volumes. For the formulas we offer, intramuscular injection is an effective and efficient delivery method.
Every vitamin injection at DaVida is administered by a licensed medical provider after reviewing your health history, current medications, and goals. Most patients experience nothing beyond mild, temporary tenderness or redness at the injection site, which typically resolves within a day or two. Vitamin injections aren’t appropriate for everyone, and certain medical conditions, medications, and pregnancy require additional consideration — which is why we evaluate every patient before their first injection rather than having you pick a shot off a menu.
Frequency depends on the formula and your goals. B-12 is typically monthly. Biotin is usually scheduled consistently over several months while results build. Vitamin C and Glutathione can be more frequent during high-stress periods or ahead of travel. We’ll recommend a starting cadence at your first visit and adjust based on how you respond — there’s no single schedule that fits every patient or every formula.
Most patients describe it as a quick pinch. The needle is small, the injection takes seconds, and there’s no downtime — you can go straight back to work or the gym. Some people notice mild soreness at the site for a day, similar to a flu shot. If you’re nervous about needles, let your provider know and they’ll walk you through it.
Yes, and many patients do. Vitamin injections are frequently added to an existing appointment — a facial, a neurotoxin treatment, or a peptide protocol — since they take only a few minutes. Vitamin C in particular is popular alongside treatments where collagen support matters. Let us know what else you’re receiving and your provider will confirm the sequencing that makes sense for you.
WHO IS A GOOD CANDIDATE FOR
VITAMIN INJECTIONS?
Vitamin shots are ideal for individuals looking for an immediate nutrient boost — especially those who struggle with energy levels, skin, hair, or nail health, or who have difficulty absorbing nutrients from oral supplements. Patients with B-12 deficiencies, fatigue, or brain fog often find particular benefit in B-12 or B-12 Ultra.
Those dealing with thinning hair or brittle nails tend to start with Biotin. And patients focused on immune resilience, collagen support, or antioxidant and detox support are typically best matched with Vitamin C or Glutathione.
