B12, D3, ALA & More: What Do These Vitamins Really Do?



In today’s wellness world, vitamins and supplements are everywhere—from IV therapy menus to your favorite smoothie bar. But what do they actually do for your body? At Calibrate IV Hydration, we believe in empowering our clients with real, science-backed info. So let’s break down some of the most talked-about nutrients—like B12, D3, ALA, and others—and explore how they contribute to your health and vitality.


Vitamin B12: The Energy Igniter
Vitamin B12 is a powerhouse when it comes to energy production and neurological health. It supports:

  • Red blood cell formation
  • Brain and nervous system function
  • DNA synthesis
  • Mood regulation and focus


Common signs of B12 deficiency: fatigue, brain fog, irritability, and even tingling in the hands and feet. B12 injections or IV therapy can offer fast support, especially for vegans or those with absorption issues.


Vitamin D3: The Sunshine Vitamin
D3 is essential for:

  • Immune system regulation
  • Calcium absorption and bone strength
  • Hormone balance
  • Mood stabilization (especially in the darker months)



Since it’s mainly synthesized from sunlight, many people—especially those indoors or in cloudy climates—can become deficient. Supplementing D3 can improve immunity and may even help protect against respiratory infections.


ALA (Alpha Lipoic Acid): The Cellular Defender
Alpha Lipoic Acid is a potent antioxidant that helps:

  • Reduce inflammation
  • Improve insulin sensitivity
  • Support healthy nerve function
  • Recycle other antioxidants like vitamin C and E



ALA is also known for its ability to help detox heavy metals and support metabolic health. It's a great addition for those with nerve pain, chronic inflammation, or oxidative stress.


Glutathione: The Master Antioxidant
Often called the “mother of all antioxidants,” glutathione:

  • Supports liver detoxification
  • Boosts immunity
  • Enhances skin clarity and glow
  • Protects against cellular damage


It’s especially popular in IV form for those looking to reset after stress, illness, or even a weekend of indulgence.


Vitamin C: Immunity + Collagen Booster
Most known for supporting immune defense, vitamin C also:

  • Aids collagen production (hello, glowing skin!)
  • Helps the body absorb iron
  • Supports tissue repair and wound healing
  • Reduces oxidative stress


It’s a staple in many IV drips for its all-around health benefits and skin-boosting effects.


The Bottom Line
While individual needs vary, these vitamins and nutrients are foundational to health—especially when delivered in bioavailable forms like injections or IVs. At Calibrate IV Hydration, we customize our treatments to your body’s unique demands, helping you feel recharged, resilient, and radiant.
