What’s inside

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 6 of its 6 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

This formula has 6 active ingredients working on hair, skin, and nail health from different angles. Biotin is a B vitamin that your body uses to build keratin, the protein in hair and nails.

Vitamin D is included for bone and calcium regulation, though at supplement doses its primary role here is systemic support. Lutein is a carotenoid that concentrates in your eyes and skin.

Grapeseed extract contains polyphenols thought to protect cells. Opextan olive fruit extract and silica round out the blend—olive for antioxidant support and silica for connective tissue structure.

The product also contains inactive ingredients like rice flour, gelatin, and food colorings for the capsule itself.

Does it work?

Strong evidence
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Strong

Clinical evidence supports at least one of this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: Promotes healthy hair, skin and nails.
  • We looked for evidence on: Aging skin, Alopecia areata, Androgenic alopecia, Asthenopia (eye strain), Atopic dermatitis (eczema), Biotin deficiency — and 4 related terms.
  • The strongest evidence on file: Biotin is rated "Likely Effective" for Biotin deficiency (Natural Medicines).
  • Also on file: Lutein is rated "Possibly Effective" for Cataracts.
  • Also on file: Biotin is rated "Insufficient Reliable Evidence To Rate" for Alopecia areata, Brittle nails.

The evidence for these ingredients varies. Biotin is likely effective for biotin deficiency, but it's rated possibly ineffective for seborrheic dermatitis and multiple sclerosis.

Lutein is possibly effective for age-related macular degeneration and cataracts, though cataracts aren't strictly a hair, skin, and nails concern. Silica is possibly effective for osteoporosis but carries insufficient evidence for hair loss (androgenic alopecia).

Grapeseed extract is possibly effective for chronic venous insufficiency—vein health and circulation, not directly hair or skin. Vitamin D works well for specific bone and calcium disorders but the evidence here is for its systemic roles, not cosmetic outcomes.

Olive fruit extract and most other claims here carry insufficient evidence in the data we hold. This product is not a proven treatment for hair loss, skin quality, or nail strength based on the monographs available.

The evidence, ingredient by ingredient Biotin Vitamin D Lutein Grape Olive Silicon

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 6 of the 6 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 6 of 6.
  • General safety write-ups exist for 6 of 6.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Most of these ingredients are generally well tolerated at typical doses. Biotin is considered safe even at fairly high doses because your body clears excess in urine; rare mild diarrhea has been reported at very high intakes (300 mg daily).

Vitamin D is safe at recommended amounts, but excessive doses over time can cause toxicity with symptoms of high blood calcium. Lutein from supplements at doses up to 20 mg daily has not caused reported adverse effects.

Grapeseed extract is well tolerated overall, though uncommon side effects include abdominal pain, diarrhea, dry mouth, headache, joint pain, and nausea; anaphylaxis to grape skin is rare but possible. Olive fruit extract can cause headache and stomach discomfort.

Silica is fine from food sources; inhaled crystalline silica in occupational settings carries serious lung risks, but oral supplements at normal levels are not associated with adverse effects.

Meds to double-check

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 2 of the 6 matched ingredients can interact with medications — Grape, Vitamin D.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; immunosuppressants / transplant drugs; heart-rhythm medications.
  • For scale: 970 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

Before you take this, double-check your medications if you're on: heart rhythm drugs (digoxin, verapamil, diltiazem)—vitamin D poses a Major risk; blood thinners or antiplatelet drugs—grapeseed extract may increase bleeding; cholesterol drugs like atorvastatin—vitamin D may reduce absorption; cyclosporine—grapeseed extract reduces absorption; or any drug metabolized by liver enzymes (CYP1A2, CYP2D6, CYP2E1, CYP3A4)—both vitamin D and grapeseed extract may affect levels. No interactions are documented for biotin, lutein, olive fruit extract, or silica with the data we hold.

The bottom line

Scorecard at a glanceFully disclosed formula with clinical evidence supporting its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

This combination is worth discussing with your pharmacist if you take heart medications, blood thinners, or cholesterol drugs—especially vitamin D at high doses or grapeseed extract, which has broad enzyme interactions. If you're pregnant, breastfeeding, or have kidney disease, check with your doctor first: silica is best avoided in pregnancy and lactation, and vitamin D toxicity is a concern in renal disease.

Biotin and lutein are generally safe in pregnancy and lactation at typical levels. Talk to your pharmacist about your full medication list before starting.

Grapeseed extract9 drug types · 910 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, grape extracts may have antiplatelet effects and may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
In vitro evidence suggests that grape extracts might decrease platelet aggregation.

Likelihood Possible Evidence D
Cyclosporine (Neoral, Sandimmune)

Ingesting grape juice with cyclosporine can reduce cyclosporine absorption.
A small pharmacokinetic study in healthy young adults shows that intake of purple grape juice 200 mL along with cyclosporine can decrease the absorption of cyclosporine by up to 30% when compared with water. Separate doses of grape juice and cyclosporine by at least 2 hours to avoid this interaction.

Likelihood Possible Evidence B
Cytochrome P450 1A2 (Cyp1A2) Substrates

Theoretically, grape juice might reduce the levels of CYP1A2 substrates.
A small pharmacokinetic study in healthy adults shows that ingestion of 200 mL of grape juice decreases phenacetin plasma levels. This is thought to be due to induction of CYP1A2.

Likelihood Possible Evidence B
Cytochrome P450 2D6 (Cyp2D6) Substrates

Theoretically, grape seed extract may increase the levels of CYP2D6 substrates.
In vitro evidence suggests that grape seed extract might inhibit CYP2D6 enzymes. However, this interaction has not been reported in humans.

Likelihood Possible Evidence D
Cytochrome P450 2E1 (Cyp2E1) Substrates

Theoretically, grape seed extract might increase the levels of CYP2E1 substrates.
In vitro and animal research suggests that grape seed proanthocyanidin extract inhibits CYP2E1 enzymes. However, this interaction has not been reported in humans.

Likelihood Possible Evidence D
Cytochrome P450 3A4 (Cyp3A4) Substrates

It is unclear if grape seed extract inhibits or induces CYP3A4; research is conflicting.
In vitro evidence suggests that grape seed extract might inhibit CYP3A4 enzymes. However, evidence from animal research shows that grape seed extract may induce CYP3A4 in the liver. So far, these interactions have not been reported in humans.

Likelihood Possible Evidence D
Midazolam (Versed)

Theoretically, long-term intake of grape seed extract might decrease the effects of midazolam.
Animal research shows that subchronic ingestions of grape seed extract can increase the elimination of intravenous midazolam by increasing hepatic CYP3A4 activity. Single doses of grape seed extract do not appear to affect midazolam elimination.

Likelihood Possible Evidence D
Phenacetin

Grape juice might decrease phenacetin absorption.
A small pharmacokinetic study in healthy adults shows that ingestion of 200 mL of grape juice decreases phenacetin plasma levels. This is thought to be due to induction of cytochrome P450 1A2 (CYP1A2).

Likelihood Possible Evidence B
Cytochrome P450 2C9 (Cyp2C9) Substrates

It is unclear if grape juice or grape seed extract inhibits CYP2C9; research is conflicting.
In vitro evidence shows that grape seed extract or grape juice might inhibit CYP2C9 enzymes. However, a small pharmacokinetic study in healthy adults shows that drinking 8 ounces of grape juice once does not affect the clearance of flurbiprofen, a probe-drug for CYP2C9 metabolism. The effects of continued grape juice consumption are unclear.

Likelihood Unlikely Evidence D
Grapeseed extract full monograph & interactions

Vitamin D8 drug types · 715 drugs

Aluminum

Vitamin D might increase aluminum absorption and toxicity, but this has only been reported in people with renal failure.
The protein that transports calcium across the intestinal wall can also bind and transport aluminum. This protein is stimulated by vitamin D, which may therefore increase aluminum absorption. This mechanism may contribute to increased aluminum levels and toxicity in people with renal failure, when they take vitamin D and aluminum-containing phosphate binders chronically.

Likelihood Probable Evidence B
Atorvastatin (Lipitor)

Vitamin D might reduce absorption of atorvastatin.
A small, low-quality clinical study shows that taking vitamin D reduces levels of atorvastatin and its active metabolites by up to 55%. However, while atorvastatin levels decreased, total cholesterol, low-density lipoprotein (LDL) cholesterol, and high-density lipoprotein (HDL) cholesterol levels did not substantially change. Atorvastatin is metabolized in the gut by CYP3A4 enzymes, and researchers theorized that vitamin D might induce CYP3A4, causing reduced levels of atorvastatin. However, this proposed mechanism was not specifically studied.

Likelihood Probable Evidence B
Calcipotriene (Dovonex)

Taking calcipotriene with vitamin D increases the risk for hypercalcemia.
Calcipotriene is a vitamin D analog used topically for psoriasis. It can be absorbed in sufficient amounts to cause systemic effects, including hypercalcemia. Theoretically, combining calcipotriene with vitamin D supplements might increase the risk of hypercalcemia.

Likelihood Probable Evidence D
Digoxin (Lanoxin)

Theoretically, hypercalcemia induced by high-dose vitamin D can increase the risk of arrhythmia from digoxin.
High doses of vitamin D can cause hypercalcemia. Hypercalcemia increases the risk of fatal cardiac arrhythmias with digoxin. Avoid vitamin D doses above the tolerable upper intake level (4000 IU daily for adults) and monitor serum calcium levels in people taking vitamin D and digoxin concurrently.

Likelihood Possible Evidence D
Diltiazem (Cardizem, Others)

Theoretically, hypercalcemia induced by high-dose vitamin D can reduce the therapeutic effects of diltiazem for arrhythmia.
High doses of vitamin D can cause hypercalcemia. Hypercalcemia can reduce the effectiveness of verapamil in atrial fibrillation. Theoretically this could also occur with diltiazem. Avoid vitamin D doses above the tolerable upper intake level (4000 IU daily for adults) and monitor serum calcium levels in people taking vitamin D and diltiazem concurrently.

Likelihood Probable Evidence B
Thiazide Diuretics

Theoretically, taking thiazide diuretics and high-dose vitamin D can increase the risk of hypercalcemia.
Thiazide diuretics decrease urinary calcium excretion, which could lead to hypercalcemia if vitamin D supplements are taken concurrently. This has been reported in people being treated with vitamin D for hypoparathyroidism, and also in elderly people with normal parathyroid function who were taking a thiazide, vitamin D, and calcium-containing antacids daily.

Likelihood Probable Evidence D
Verapamil (Calan, Others)

Hypercalcemia induced by high-dose vitamin D can reduce the therapeutic effects of verapamil for arrhythmia.
Hypercalcemia due to high doses of vitamin D can reduce the effectiveness of verapamil in atrial fibrillation. Avoid vitamin D doses above the tolerable upper intake level (4000 IU daily for adults) and monitor serum calcium levels in people taking vitamin D and verapamil concurrently.

Likelihood Probable Evidence B
Cytochrome P450 3A4 (Cyp3A4) Substrates

Vitamin D might induce CYP3A4 enzymes and reduce the bioavailability of CYP3A4 substrates.
There is some concern that vitamin D might induce CYP3A4. In vitro research suggests that vitamin D induces CYP3A4 transcription. Additionally, observational research has found that increased UV light exposure and serum vitamin D levels are associated with decreased serum levels of CYP3A4 substrates such as tacrolimus and sirolimus, while no association between UV light exposure or vitamin D levels and levels of mycophenolic acid, a non-CYP3A4 substrate, was found. A small, low-quality clinical study shows that taking vitamin D reduces levels of the CYP3A4 substrate atorvastatin and its active metabolites by up to 55%; however, the clinical effects of atorvastatin were not reduced. While researchers theorized that vitamin D might induce CYP3A4, this proposed mechanism was not specifically studied.

Hair, Skin & Nails Super Formula by Purity Products: Common Questions

Does Hair, Skin & Nails Super Formula by Purity Products interact with any medications?
Yes. Based on its ingredients, Hair, Skin & Nails Super Formula has a known interaction with 969 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Hair, Skin & Nails Super Formula contains 6 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
Is this safe to take while I'm pregnant?
Biotin and lutein are rated likely safe in pregnancy at recommended amounts. Vitamin D is okay at standard doses but use only under your doctor's guidance. Grapeseed extract is likely safe, but concentrated supplements haven't been well studied. Silica, however, doesn't have enough safety data—avoid it unless your doctor approves. Talk with your doctor about the full formula before starting, especially if you're taking any other prenatal supplements.
Will this really help my hair and nails grow?
The evidence we hold doesn't show these ingredients are proven treatments for hair loss or nail strength. Biotin is likely effective for biotin deficiency, but possibly ineffective for hair-related conditions. Silica carries insufficient evidence for hair loss. This product may support overall nutrition, but don't expect it to reverse hair thinning or weak nails on its own—talk to your doctor if those are ongoing concerns.
What's silica, and why is it in here?
Silica is another name for silicon, a mineral your body uses to build connective tissue that supports bones, skin, and hair structure. It's rated possibly effective for osteoporosis. Orally, the small amounts in food and most supplements are well tolerated, but long-term safety at high doses hasn't been studied thoroughly.
Can I take this with my blood thinner?
Not without checking first. Grapeseed extract has antiplatelet properties and may increase bleeding risk when combined with blood thinners or antiplatelet drugs. Use the medication checker on this page with your specific drug name, and always tell your pharmacist or doctor before adding any supplement to a blood thinner.
What are the side effects?
Most people tolerate these ingredients well. Biotin at very high doses (300 mg daily) has rarely caused mild diarrhea. Grapeseed extract can cause abdominal pain, diarrhea, dry mouth, headache, joint pain, and nausea. Olive fruit extract may cause headache or stomach discomfort. Anaphylaxis to grape is rare but possible. Stop and call your doctor if you notice any unexpected symptoms.
Is this okay if I'm breastfeeding?
Biotin and lutein are rated likely safe while breastfeeding. Grapeseed extract is likely safe, though concentrated supplement safety hasn't been fully studied. Vitamin D is acceptable at recommended doses; check with your doctor about higher amounts. Silica doesn't have enough safety data—avoid it unless your doctor approves. Discuss the full formula with your doctor or pharmacist before starting.
