Analysis

The 2,500mcg of biotin is a therapeutic amount that may help support the strength of your nails and the quality of your hair. Vitamins C and E are also included to provide basic antioxidant support for your skin.

While the keratin dose is minimal at 50mg, the gummy format makes it easy to stay consistent with your routine. These are helpful for basic beauty maintenance but aren't intended for intensive repair.

Pros

High dose of biotin (2,500mcg)
Enjoyable grapefruit flavor
Convenient gummy format
Includes antioxidant vitamins C and E
Affordable price point

Cons

Contains added sugars
Very low dose of keratin (50mg)
Lower quantity of servings (30)

Warnings

Contains sugar and carbohydrates
Monitor biotin if having thyroid lab tests
Keep out of reach of children due to candy-like taste

Nutrient quality

High impact

Biotin and vitamins C and E are included at functional doses for general beauty support. The keratin dose is quite low, which may limit its structural effectiveness compared to more concentrated options.

Ingredient transparency

Highest impact

All active vitamins and structural proteins are clearly labeled with specific amounts. The labeling provides good clarity regarding the inclusion of carbohydrates and calories in the gummy base.

Customer satisfaction

Highest impact

High ratings and a large review volume indicate significant consumer trust and satisfaction. Users frequently praise the flavor and ease of consumption, aligning with the brand's focus on experience.

Value for money

High impact

The cost per serving is higher than many tablet options, reflecting the premium for the gummy format. While convenient, the low dose of keratin reduces the overall functional value.

Formula Quality

This beauty-focused gummy provides a therapeutic 2,500 mcg dose of bioactive d-biotin to support keratin production and nail plate thickness. The inclusion of 50 mg of keratin provides a direct source of the primary structural protein needed for resilient fingernails and toenails.

While the gummy format is convenient and tasty, it contains added sugars which may be a drawback for some users. The dosage of keratin is relatively low, but the overall synergy with biotin and vitamin E makes this a well-aligned choice for improving nail appearance and strength.

Formula Quality

A therapeutic 2,500 mcg dose of d-Biotin is combined with Keratin to support the structural strength and resilience of skin and hair tissues. These components work together to maintain the integrity of keratinized structures for a smoother appearance.

Vitamin C and Vitamin E provide additional antioxidant protection, although their dosages are relatively low compared to more concentrated antioxidant supplements. While excellent for structural integrity, the product does not provide the essential fats needed to reinforce the skin's moisture barrier.

Formula Quality

Combines 2,500 mcg of biotin with a small dose of keratin and antioxidant vitamins C and E. This formula is explicitly designed to support the structural components of hair and protect follicles from environmental damage.

The biotin dosage is aligned with beauty standards, but the 50 mg of keratin is likely too low to offer significant structural benefit. Vitamins C and E provide necessary antioxidant support to maintain a healthy scalp environment.
