B7 · HIGH-DOSE

Biotin,

at clinical strength.

5,000 mcg of D-Biotin per capsule — the B-vitamin that drives carboxylase enzymes behind fatty acid, amino acid, and glucose metabolism. Structural support for hair, skin, and nails follows the same chemistry.

Biotin bottle
DOSE
5,000 mcg D-Biotin per capsule

The form that works.

D-Biotin is the biologically active stereoisomer — the form your carboxylase enzymes actually use. Clinical-level dosing supports macronutrient metabolism and keratin-dependent tissue turnover.

METABOLISM
5 carboxylase enzymes

A cofactor, not a fad.

Biotin is the required cofactor for five carboxylase enzymes that sit at the junction of carbohydrate, fat, and amino-acid metabolism. Low biotin quietly disrupts all three pathways at once.

DAILY DOSE
1 capsule daily with food

Simple, steady, specific.

One capsule with a meal. Biotin is water-soluble and well-tolerated, making it easy to layer into a methylation or hair-and-skin protocol without stacking bulk on the rest of the regimen.

MAY BENEFIT

One cofactor,
many pathways.

01
Hair, skin & nail structure
Biotin supports keratin synthesis — the structural protein behind strong nails and resilient hair shafts.
02
Carbohydrate metabolism
Biotin-dependent carboxylases drive gluconeogenesis and help the body manage glucose substrates efficiently.
03
Fatty acid synthesis
Acetyl-CoA carboxylase is biotin-dependent — the committed step in building fatty acids from dietary precursors.
04
Amino acid metabolism
Propionyl-CoA and methylcrotonyl-CoA carboxylases run on biotin, clearing intermediates from leucine and odd-chain breakdown.
05
Nervous system support
B-vitamin adequacy underpins normal neurological function; biotin deficiency is a recognized cause of neurological symptoms.
06
MTHFR protocol support
Biotin layers cleanly with methylation cofactors in practitioner-designed B-vitamin protocols.

Questions

Frequently asked.

Why such a high dose of biotin?
5,000 mcg is the clinical range studied for hair, skin, and nail support and for metabolic cofactor saturation. Lower food-level doses (30–100 mcg) cover basic RDA needs but do not reach the concentrations used in most biotin research. Work with your practitioner if you need a lower dose.
Will biotin interfere with lab tests?
Yes — this is important. High-dose biotin can skew immunoassay-based lab results, including thyroid panels (TSH, T4, T3), troponin, and some hormone tests. Stop biotin at least 48–72 hours before bloodwork and tell the ordering clinician you take it. Your practitioner can advise on the right washout window.
Who is this designed for?
Adults working on hair, skin, or nail concerns; those with metabolic or methylation protocols that call for saturated B-vitamin support; and patients whose practitioner has flagged low biotin or carboxylase-pathway bottlenecks. Pregnant or nursing patients should use a prenatal-specific B-vitamin under medical guidance.
How long before I notice a difference?
Hair and nail changes follow growth cycles — expect 8–12 weeks for visible changes in nail strength and 3–6 months for hair shaft quality. Metabolic effects (energy stability, recovery) tend to show up sooner, within the first 2–4 weeks of consistent use.
Can I take biotin with Methylation Complete or other B-vitamin products?
Yes — biotin is commonly paired with a broader B-complex or methylation protocol. Most B-complex products include low-dose biotin; stacking a dedicated high-dose biotin on top is a common practitioner move when hair, skin, or nail support is the goal.
Is it safe during pregnancy or while breastfeeding?
Biotin at prenatal doses is generally considered safe, but 5,000 mcg is well above standard prenatal dosing. Consult your healthcare practitioner before use during pregnancy or lactation — they may recommend a lower prenatal-specific formula instead.
