Study, Trial or Testing Result Summary
Members Only25 human studies · 17 improved
1 of these 25 human studies gave the ingredient by injection, not by mouth.
Biotin is the only ingredient here at a full studied dose. In a randomized trial of 105 adults, 1.25 milligrams of biotin daily for 90 days reduced hair fall and sped hair growth, with no side effects reported [1]. This gummy gives 2500 micrograms, which is more than that amount. Another trial found less hair fall and thicker hair with weekly biotin injections, but it had no placebo group [2]. Not every study agrees. In women after weight-loss surgery, only 23 percent of those low in biotin saw less hair loss after 3 months of 1000 micrograms daily [3]. Keratin is below the studied dose. This product has 50 milligrams, while the one trial used 500 milligrams together with vitamins and minerals [4]. Vitamin E is only a trace amount. The small trial that showed more hair used 100 milligrams of a different form of vitamin E [5], while this gummy has 7.5 milligrams. Vitamin C has no good evidence on its own for hair. The one trial mixed it with other ingredients [6], and two surveys gave opposite results [7][8]. Animal and cell studies are never counted.

Members Only19,155 reviews · 87% positive
Customer feedback for OLLY Undeniable Beauty gummies reveals a generally positive reception, with many users praising the product's effectiveness, particularly for nail strength and growth. Several reviewers, like AmandaZ and ErciadelyS, reported significant improvements in their nails, with some experiencing noticeable growth and increased strength within a short period, such as "about a week." CrystalJ highlighted the product's efficacy for hair growth, even noting its benefits for post-chemo hair recovery, and commended its value and portability. CassieR echoed sentiments of overall effectiveness and high quality, stating these vitamins are her favorite among similar products. A recurring positive theme is the pleasant taste, with many customers finding the gummies enjoyable to consume. Anchorgirl, for instance, mentioned that the taste was so good she "forgot that it’s a vitamin." Ladystaci_8890 also noted a pleasant taste with no weird aftertaste, even though she didn't experience the desired beauty benefits. However, the taste profile appears to be a point of contention for some, particularly concerning a "new formula." Rose P expressed strong dissatisfaction with a "gross new formula," describing the taste as unpleasant and noting a change in color, which led her to discontinue use despite acknowledging that her nails had grown well with the product. CrystalO also mentioned missing the "old formula" due to a perceived "watered down" flavor in the newer version, though she still found it effective as a Vitamin C supplement for sore throats, indicating a broader perceived benefit beyond beauty. While many users experienced positive results, some, like ladystaci_8890, reported no noticeable changes to their hair, skin, or nails even after several months of consistent use, suggesting that individual results may vary. Despite these mixed experiences regarding taste and efficacy for all users, the majority of reviews highlight the gummies as an effective and generally palatable daily supplement for supporting hair, skin, and nail health, with a strong emphasis on nail improvement and overall quality. The product's ease of use, requiring just two gummies without food or water, also contributes to its appeal among consumers.
Biohacker Summary
Members Only9 of 10 recommend it
On biotin, the main ingredient, the panel is split and few give strong backing: three of ten recommend it, four are neutral, and three warn. Those who recommend it take it for hair, with two linking it to hair follicle health and growth and one to keratin and stronger hair, and another says low biotin may show up as thinning hair; one names eggs, almonds and salmon as food sources. The cautions are that two of them say to avoid biotin supplements before a testosterone blood test because they can throw off results, and one calls it overhyped and says enough protein is probably more useful for hair, skin and nails. No one gave a dose or a preferred form, and none described pairing it with anything or stopping it. Vitamin C is a smaller ingredient in this product and is mostly supported by the panel for skin and collagen, while vitamin E is also a smaller ingredient with mixed views, including a warning against the synthetic form for long-term use.
