OVERVIEW

Biotin, also known as Vitamin B7 or Vitamin H, is a water-soluble B-complex vitamin essential for the metabolism of fats, carbohydrates, and proteins. As a coenzyme, biotin plays a critical role in maintaining healthy hair, skin, nails, nervous system function, and energy production at the cellular level.

Biotin deficiency, while rare, can result in hair loss, neurological symptoms, and skin disorders, making supplementation important in certain clinical or aesthetic contexts. It is commonly included in IV nutrient therapy protocols for beauty, metabolic support, and neurological health.

CHEMICAL PROFILE

Molecular Formula: C₁₀H₁₆N₂O₃S
Molecular Weight: 244.31 g/mol
Solubility: Water-soluble
Stability: Stable under acidic and neutral pH, sensitive to oxidation and UV light

MECHANISM OF ACTION

Biotin functions as a coenzyme for five key carboxylases, which are enzymes involved in critical metabolic pathways:

1. Fatty Acid Synthesis
Facilitates conversion of acetyl-CoA to malonyl-CoA via acetyl-CoA carboxylase

2. Amino Acid Catabolism
Supports leucine degradation and branched-chain amino acid metabolism

3. Gluconeogenesis
Assists in the formation of glucose from non-carbohydrate sources during fasting

4. Cellular Growth and Repair
Required for gene regulation and the synthesis of structural proteins in skin, hair, and nails

5. Mitochondrial Energy Production
Essential for ATP generation and energy homeostasis

CLINICAL AND WELLNESS BENEFITS

1. Promotes Healthy Hair, Skin, and Nails
Enhances keratin structure and may reduce hair thinning and brittle nails

2. Supports Metabolic Health
Improves metabolism of glucose, fatty acids, and amino acids
May support blood sugar regulation in diabetics

3. Neurological Support
Protects myelin sheath integrity, improving nerve function
Used in protocols for peripheral neuropathy and multiple sclerosis adjunctive care

4. Pregnancy and Fetal Development
Crucial for embryonic growth and reducing the risk of birth defects

5. Anti-Inflammatory and Cognitive Health
May have a role in reducing inflammation and supporting cognitive function in deficient individuals

IV ADMINISTRATION GUIDELINES

  • Form: Biotin for injection (typically D-Biotin USP grade)
  • Typical Dosage:
    Standard wellness: 5–10 mg per session
    High-dose protocols (neurological): up to 300 mg/day under physician supervision
  • Dilution & Infusion:
    Dilute in 100 mL normal saline or dextrose
    Infuse over 20–30 minutes
    Combine with B-complex, Thioctic Acid (ALA), or Glutathione for synergistic support

SAFETY AND SIDE EFFECTS

  • Generally Recognized as Safe (GRAS)
    No upper tolerable intake level established due to low toxicity
  • Mild Side Effects (rare):
    Skin rash, gastrointestinal upset, or acne-like eruptions at very high doses
  • Laboratory Interference:
    High-dose biotin (>5 mg/day) may interfere with certain lab tests (thyroid hormones, troponin, etc.)
    Patients should inform clinicians before bloodwork

CONTRAINDICATIONS & CAUTIONS

  • Avoid or use with caution in:
  • Patients undergoing lab testing for thyroid or hormone panels
  • Individuals with known allergies to biotin or excipients in injectable forms
  • Use under supervision in pregnant or breastfeeding women at high doses

NATURAL FOOD SOURCES OF BIOTIN

Biotin is present in various whole foods: Food Source Approx.

  • Eggs (cooked, 1) 10–25 mcg
  • Liver (3 oz) 30–40 mcg
  • Almonds (¼ cup) 15 mcg
  • Sweet potatoes 2–4 mcg
  • Salmon (3 oz) 4–5 mcg
  • Spinach (½ cup) 0.5–2 mcg

COMPARISON: BIOTIN VS. OTHER B-COMPLEX VITAMINS

  • Biotin (B7) is distinct for its role in keratin and fatty acid metabolism, while other B vitamins like B1 (Thiamine) or B12 (Cobalamin) focus more on neurological and red blood cell functions
  • Works synergistically with Vitamin B5 (Pantothenic Acid) and ALA (Thioctic Acid) in beauty, nerve, and energy protocols

CONCLUSION

Biotin (Vitamin B7) is a foundational nutrient for metabolic vitality, aesthetic wellness, and neurological balance. Whether used to strengthen hair and nails, support energy metabolism, or enhance nerve health, biotin’s multifunctional benefits make it a key ingredient in IV nutrient therapy, especially in aesthetic medicine and functional health programs.
