Analysis

The ch-OSA complex in this product is widely used for its ability to support the natural production of collagen and keratin. Regular intake may help increase the diameter of hair shafts and significantly reduce the splitting or breaking of nails.

By providing silicon in a stabilized liquid-filled capsule, it ensures that the mineral is delivered in a form the body can actually use. This 60-day supply makes it easier to stay consistent, which is key for seeing structural changes.

Pros

  • Better price per serving than the 30-count
  • Highly effective for keratin-rich tissues
  • No artificial colors or preservatives
  • Compact capsules are easy to swallow

Cons

  • Higher upfront cost than smaller sizes
  • Only addresses the silicon pathway for hair and nails

Warnings

  • Ensure you drink plenty of water when taking supplements for best results
