What makes OLLY different from other beauty gummies?

OLLY includes keratin (50mg) alongside biotin — most competitors offer biotin only. The biotin dose is moderate (2500mcg), which is closer to the dose used in clinical studies and less likely to cause acne than 5000-10000mcg products. The grapefruit flavor is widely praised. Downside: contains gelatin (not vegan).

Is 2500mcg biotin enough to see results?

Yes — the landmark 1993 Cutis study showing 91% improvement in brittle nails used 2.5mg (2500mcg) daily. Higher doses haven't been proven more effective in clinical research. In fact, 2500mcg may be the sweet spot: evidence-based dosing with lower risk of acne side effects compared to 5000-10000mcg products.

Nails stopped peeling within 6 weeks

Chose OLLY specifically because it includes keratin, not just biotin. After about 6 weeks my nails stopped peeling — they'd been terrible since I removed gel polish. The grapefruit flavor is genuinely delicious, not artificial tasting at all. At $14 from Target, this is way more reasonable than premium brands. Wish they had a vegan version since these contain gelatin.

Moderate biotin dose = no breakouts

The moderate biotin dose (2500mcg instead of 5000-10000mcg) was key for me — high biotin made me break out badly. After 3 months my hair feels thicker and my hairdresser noticed less breakage. I can grab them at Target with my groceries. Simple, effective, no acne. For anyone who's had the biotin-acne problem, this lower dose is the solution.

Taking these for over a year — they really work

Been on OLLY for over a year now. My nails are the strongest they've ever been, my skin looks clearer, and my hair shedding is way down. They taste like grapefruit candy so I actually look forward to taking them. After 2-3 months of daily use I noticed the biggest change — beautiful nails I could never grow before. Affordable and effective.
