Mobile vitamin injections, brought to your door.

What does a B12 shot do?

Vitamin B12 plays a role in the body's normal energy metabolism, red blood cell formation, and nervous system function. An intramuscular injection delivers B12 directly, bypassing digestion — which is why clients on plant-based diets or with absorption concerns often choose shots. If your B12 levels aren't low, you may not notice a dramatic difference.

We'd rather be honest than oversell: research suggests there's little added benefit to extra B12 if you're not actually low. The groups where B12 status matters most are vegans and vegetarians, older adults, and people with digestive or absorption issues. If that's you, a shot can be a simple way to keep levels topped up.

Our B12 is available as methylcobalamin or cyanocobalamin. Both are well-studied forms; methylcobalamin is the body's active form, while cyanocobalamin is highly stable and widely used. Your provider can help you choose. For general wellness most clients book a shot monthly, or a four-shot series for a weekly cadence, alongside their full IV and injection menu favorites.

How often should you get a B12 injection?

For general wellness, most clients schedule B12 injections weekly to monthly, depending on their goals, diet, and our medical team's guidance. Deficiency treatment follows different, provider-directed protocols. Many WholeHealth Hydration clients pair a monthly shot with an IV appointment or book a four-shot series for a weekly cadence across the month.

A four-pack is the most economical way to run a weekly rhythm — it saves roughly 12% versus single shots and locks in the add-on convenience across the month. Families in Chino Hills, Corona, and Rancho Cucamonga often book a household series so several people share one visit. Your ideal cadence is always a conversation with our provider, not a fixed rule.

NAD+ injection or NAD+ IV — which should I choose?

An NAD+ IV delivers a larger dose over a 1–4 hour monitored session; an NAD+ injection takes minutes, uses a smaller dose, costs less, and is typically repeated 1–3 times weekly as ongoing support. Many clients start or maintain with injections and book IV sessions for deeper protocols. NAD+ levels naturally decline with age.

NAD+ is a coenzyme every cell uses to help power hundreds of reactions, from converting food into energy to the body's natural repair cycles. Research suggests levels fall with age, which is why it's become a centerpiece of longevity wellness. We do not claim NAD+ reverses aging — the honest framing is cellular-energy support, not a cure.

The practical difference is dose, time, and price. A shot is a fast, repeatable touchpoint you can add to almost any visit; a drip is the deeper, monitored session. Curious which fits your goals? Read is NAD+ IV therapy worth it, or explore the full NAD+ IV therapy page.

What is a glutathione shot for?

Glutathione, often called the body's "master antioxidant," is studied for its role in supporting natural antioxidant and detoxification processes. Many clients add it to a skin-wellness routine for a healthy-looking glow, typically as a weekly series. It's also the most popular IV add-on. Individual results vary, and we make no skin-lightening claims.

To be clear and compliant: we do not offer or claim skin-lightening or whitening. The FDA has warned against injectable glutathione marketed for skin bleaching, and it is not FDA-approved for cosmetic use. What we support is a normal antioxidant routine some clients feel contributes to a healthy-looking complexion. Whether that's noticeable varies from person to person.

Glutathione is our most-requested pairing with a hydration drip — many clients add it to a Myers' Cocktail IV or book the Radiance Combo with B12. As a shot it's usually run as a weekly series; the four-pack keeps that rhythm affordable.

Is a vitamin D injection better than a daily supplement?

Not for everyone — oral vitamin D3 works well for most people. Injections are an option our medical team discusses for adults who struggle with daily supplements or don't absorb oral D well. Vitamin D supports normal bone health, muscle function, immune function, and mood balance, and injectable vitamin D is prescription-only in the U.S.

Because injectable vitamin D is prescription-only, this shot is a good example of our provider-order model in action: a licensed physician, NP, or PA reviews your history and issues the order before your RN administers it. If a daily pill is working for you, we'll happily tell you to keep it up — a shot is simply another tool for people who need one.

Vitamin shot or IV drip — which is better?

They serve different purposes. An IV delivers fluids plus multiple nutrients with complete absorption over a 45–60 minute session; an IM shot delivers one targeted nutrient in under five minutes at roughly one-third to one-fifth the price of a drip. Shots win for speed, cost, and routine; drips win for hydration and multi-nutrient sessions.

If you're mostly after one nutrient on a busy day, a shot is the efficient choice. If you want fluids, several nutrients, and a full reset, a drip earns its longer session. Many clients do both — a monthly drip anchored by weekly shots. Curious about full drip pricing? Our mobile IV therapy cost guide breaks down every 2026 number.
