Double Wood Supplements Keratin Hair Growth Vitamin 500mg — 120 Vegan Capsules for Hair & Nails

Keratin Hair Growth Vitamin by Double Wood Supplements is a 500mg-per-serving, 120-count vegan keratin formula designed to support hair, skin, and nail resilience and manage age-related keratin loss.

Keratin is a structural protein that helps hair stay flexible, smooth, and less prone to breakage. As we age or face environmental stressors, keratin levels can decline, which may make hair drier and more fragile. This Double Wood supplement delivers a standardized 500mg daily dose in an easy-to-take capsule aimed at complementing a balanced diet and hair-care routine.

How does this keratin supplement fit into a daily routine?

Take one or the suggested serving daily with food to help absorption and reduce the chance of digestive upset. The capsule format is travel-friendly and simple to add alongside other daily vitamins.

• 500mg keratin per serving for consistent intake
• 120 capsules — a two- to four-month supply depending on dosing
• Vegan-safe formulation suitable for many diets
• Best taken with a meal that contains some fat for optimal nutrient uptake

What results can I realistically expect and on what timeline?

Individual responses vary, but studies cited for keratin show measurable improvements in hair strength and nail condition over weeks to months. Early changes in hair texture and strength are often noticed within one month, with more pronounced effects by three months when used consistently.

• Possible early improvements in hair strength within 30 days
• More noticeable texture and resilience changes around 60–90 days
• Nail strength and smoothness may improve with continued use

Is this product safe and how is it tested?

Double Wood emphasizes careful sourcing and third-party testing to ensure purity and potency. The formula is created to be compatible with common dietary preferences and is manufactured under quality controls that reduce contamination risks.

• Manufactured with third-party testing protocols
• Produced to meet industry quality standards for supplements
• Formulated to be vegan-safe and free of common animal-derived keratin sources

How does keratin support hair, skin, and nails without topical products?

Keratin is a structural protein; taken as an oral supplement it provides building blocks that may support the body’s own keratin production. While topical products condition the hair externally, oral keratin aims to influence internal support systems related to hair and nail integrity.

• Supports internal protein availability for hair structure
• Complements topical hair-care rather than replacing it
• May support nail strength and reduce brittleness over time

Who is this for? This Double Wood Keratin Hair Growth Vitamin is intended for adults seeking a daily, vegan-friendly keratin supplement to support hair texture, strength, and overall resilience, and for those wanting a supplement to complement topical hair care and balanced nutrition. It’s suitable for men and women looking to address age-related keratin decline or environmental stress on hair and nails. If you are pregnant, nursing, have a medical condition, or are taking prescription medications, consult a healthcare professional before beginning any new supplement.
