The science behind NUTRAVESSA
Doctor formulated. Science + nutrition + botanicals.
Why we built a 4-in-1 formula instead of another basic biotin supplement — and exactly what the research behind it does and doesn't show.

Understanding hair wellness
Shedding and thinning
have many causes.
Everyone sheds hair every day. When shedding or thinning increases, the cause can be very different from one person to the next.[9]
- Genetics & family history
- Hormonal changes
- Stress
- Illness or recovery
- Pregnancy & postpartum
- Nutritional shortfalls
- Medications
- Styling & scalp care
Where nutrition fits
Hair follicles are among the most active cells in the body, and they rely on a steady supply of nutrients. NUTRAVESSA is designed to support healthy-looking hair and normal hair wellness through four approaches — not to treat hair loss.* A supplement can't address every cause, which is why we built a broad, doctor-formulated formula rather than a single-ingredient hair vitamin.
If you notice sudden, patchy or heavy hair loss, please talk to a healthcare professional. If you're having lab work done, tell your doctor you take biotin — it can interfere with some lab tests.[10]
Why not just biotin?
We didn't build another basic biotin supplement.
Biotin matters — it's recognized for its role in the maintenance of normal hair. But hair wellness involves nutrition, the follicle environment, everyday stress and the building blocks of keratin. So NUTRAVESSA combines botanicals, Sensoril® ashwagandha, amino-acid nutrition and essential vitamins and minerals in one daily formula.*
Advanced 4-in-1 hair support
One formula.
Four approaches.
Hair wellness is more than one nutrient. Tap each pillar to see what's inside and why.
Pillar 01 · Hair growth support*
Silicon & biotin nutrition
This pillar pairs a complex of bonded arginine silicate and magnesium biotinate (a source of silicon and biotin) with 2,500 mcg of biotin. Biotin is recognized for its role in the maintenance of normal hair.[4]*
- Arginine Silicate & Magnesium Biotinate160 mg
- Biotin2,500 mcg
Pillar 02 · DHT support*
Botanicals studied for their role in DHT pathways
DHT (dihydrotestosterone) is a hormone made from testosterone by the enzyme 5-alpha-reductase, and it is one of many factors involved in the hair growth cycle. Saw palmetto and pumpkin seed are botanicals that have been researched for their interaction with this pathway — mostly in studies of people with specific hair or prostate conditions rather than healthy adults, and often using different preparations than the extracts in this formula.[11–12] We include them as botanical support within a complete formula.* NUTRAVESSA is not a drug, is not proven to block DHT, and is not a treatment for hair loss.
- Pumpkin Seed Extract400 mg
- Saw Palmetto Extract320 mg
Pillar 03 · Stress support*
Sensoril® Ashwagandha for everyday stress
Everyday stress is part of overall wellness. Sensoril® is a standardized ashwagandha extract that was evaluated at 125 mg per day in a randomized, double-blind, placebo-controlled study of chronically stressed adults,[3] and is included to support a healthy response to everyday stress.*
- Sensoril® Ashwagandha125 mg
Pillar 04 · Hair nutrition support*
The nutritional foundation
Biotin, zinc and selenium are nutrients recognized for their role in the maintenance of normal hair.[4–6] Hair is built largely from keratin, a protein rich in the sulfur amino acid cysteine[7] — so the formula adds 200 mg of L-cysteine, plus vitamin D3.* Nutrient shortfalls are one of many factors linked to hair changes; supplementation is most relevant when your diet falls short.[8]
- Biotin2,500 mcg
- Zinc15 mg
- Selenium70 mcg
- Vitamin D32,000 IU (50 mcg)
- L-Cysteine200 mg

Evidence behind the formula
Not every ingredient
has the same evidence.
We'd rather tell you exactly where the science stands than make every ingredient sound equally proven.
Clinically studied branded ingredient
Human studies of the specific ingredient and dose
- Sensoril® Ashwagandha · 125 mgRandomized, double-blind, placebo-controlled study in chronically stressed adults.[3]
Nutritional support
Essential nutrients with recognized roles
Botanical & amino-acid support
Supporting ingredients with more limited evidence
- Pumpkin Seed Extract · 400 mg & Saw Palmetto Extract · 320 mgTraditional botanicals. Human research has mostly studied people with specific hair or prostate conditions — not healthy adults — and often different preparations (for example, pumpkin seed oil) than the extracts in this formula.[11–12]
- L-Cysteine · 200 mgA sulfur-containing amino acid; hair keratin is rich in cysteine.[7] Direct evidence that supplementation changes hair in healthy adults is limited.
