B12, NAD+, Glutathione, and MICC: Which Vitamin Injection Is Right for You?
A clear, honest guide to vitamin and wellness injections at Luna Med Spa Burlington, what each one does, who benefits most, and how to choose.

Why Are Vitamin Injections More Effective Than Oral Supplements?
When you take a vitamin orally, it must survive digestion, pass through the gut wall, navigate the liver's first-pass metabolism, and finally enter circulation, at which point a significant portion of the original dose has been lost. For many vitamins, oral absorption rates are highly variable and often poor, particularly with digestive sensitivities, certain medications, or conditions affecting nutrient uptake.
An intramuscular (IM) injection delivers the nutrient directly into the muscle tissue, where it enters the bloodstream rapidly and in full dose, bypassing the GI tract entirely. The difference in bioavailability is meaningful, and for clients with confirmed deficiencies or specific wellness goals, it's often the difference between a supplement that works and one that doesn't.
B12 Methylcobalamin, Energy, Focus, and Neurological Support
Vitamin B12 is essential for red blood cell production, neurological function, DNA synthesis, and cellular energy metabolism. Deficiency, which is more common than most people realize, presents as persistent fatigue, brain fog, mood disruption, and tingling in the extremities.
At Luna Med Spa, we use B12 Methylcobalamin, the neurologically active form that the body can use directly, without conversion. The more common cyanocobalamin form requires conversion, and individuals with certain genetic variants (particularly MTHFR) may not convert it efficiently.
B12 Methylcobalamin Is Best For
- Persistent fatigue or low energy that doesn't improve with sleep.
- Brain fog, difficulty concentrating, or memory concerns.
- Vegetarians and vegans, dietary B12 comes exclusively from animal sources.
- Adults over 50, B12 absorption declines with age
- Those taking metformin, which depletes B12 over time.
- Anyone with digestive conditions affecting nutrient absorption.
NAD+, Cellular Energy and Longevity
NAD+ (nicotinamide adenine dinucleotide) is a coenzyme present in every cell, essential for energy production, DNA repair, and metabolic processes. NAD+ levels decline significantly with age, and this decline is associated with reduced cellular efficiency, slower recovery, and cognitive changes.
NAD+ injections deliver this coenzyme directly where it's needed, supporting mitochondrial function, cognitive clarity, mood regulation, and metabolic health.
NAD+ Is Best For
- Clients experiencing fatigue related to aging or metabolic changes.
- Those seeking cognitive support, focus, clarity, mental energy.
- Perimenopause and menopause, hormonal transitions affect cellular energy significantly.
- Active clients seeking improved recovery after exercise or physical demands.
- Anyone interested in proactive cellular health and longevity support.
Glutathione, The Master Antioxidant
Glutathione is the body's most powerful endogenous antioxidant, produced in every cell, responsible for neutralizing free radicals, supporting liver detoxification, and protecting cells from oxidative damage. Like NAD+, glutathione levels decline with age, chronic stress, and illness.
Injected glutathione delivers a concentrated antioxidant dose that oral supplementation cannot reliably achieve. Benefits clients most commonly report include improved skin clarity and radiance, better recovery from illness, and a general sense of improved vitality.
Glutathione Is Best For
- Clients seeking skin brightening and a more even, radiant complexion.
- Those recovering from illness, high stress periods, or environmental exposures.
- Support for liver health and detoxification.
- Anyone with high oxidative load, athletes, frequent travellers, those in high-stress environments.
MICC (Lipotropic Injection), Metabolic and Fat Metabolism Support
MICC is a lipotropic compound injection combining Methionine, Inositol, Choline, and Cyanocobalamin (a B12 form), four nutrients that play specific roles in fat metabolism, liver function, and cellular energy. These compounds support the liver's ability to process and export fat, reduce fat accumulation, and promote efficient energy metabolism.
MICC is not a weight loss injection, it won't replace diet and exercise or directly dissolve fat. But for clients actively working on body composition goals, it supports the metabolic environment in which fat is more efficiently processed.
MICC Is Best For
- Clients actively working on weight management or body composition goals.
- Those experiencing fatigue or sluggishness related to metabolic changes.
- Support for liver function in those with high dietary fat intake.
- Pairing with other wellness strategies, not as a standalone weight loss treatment.
Vitamin D3, Immune, Mood, and Bone Health
Vitamin D deficiency is remarkably common in Ontario, our latitude and winter months mean months of insufficient sun exposure. Vitamin D3 is essential for calcium absorption and bone health, immune regulation, mood and mental health, and reducing inflammation.
For clients, whose dietary intake is insufficient and who aren't absorbing oral supplements effectively, IM Vitamin D3 injections provide a reliable, direct dose.
Vitamin Injection Comparison at a Glance
Can I Combine Vitamin Injections?
Yes, and many of our clients do. Common combinations include B12 with Glutathione (energy plus antioxidant support), or MICC with B12 for metabolic wellness. Your Registered Nurse will review your health history and goals at consultation and recommend what's appropriate, including any interactions to be aware of with current medications or supplements.
Frequently Asked Questions: Vitamin Injections in Burlington
Do vitamin injections hurt?
Most clients describe a brief pinch or mild pressure at the injection site, comparable to a standard blood draw or vaccination. Intramuscular injections are administered into the deltoid (upper arm). Discomfort is minimal and short-lived.
How quickly will I feel the effects?
B12 Methylcobalamin clients often notice improved energy within 24–48 hours. NAD+ effects on clarity and energy typically develop over 1–3 days. Glutathione skin benefits develop progressively over weeks with regular sessions. MICC supports metabolic processes gradually, effects are cumulative rather than immediate. Individual responses vary.
Do I need a blood test before vitamin injections?
A blood test is not required before most vitamin injections at Luna Med Spa Burlington, though we do recommend reviewing your health history and any known deficiencies at consultation. If you have relevant bloodwork (B12 levels, Vitamin D levels), please bring it, it helps us personalize your treatment.
Is there any downtime after vitamin injections?
No downtime. Most clients resume normal activities immediately after their session. Mild soreness at the injection site is possible for 24–48 hours. Sessions take approximately 15–20 minutes total.
