    This product is great

    I bought these supplements primarily to address my slow-growing, weak nails (they’d chip or bend before I could get a manicure), but I ended up loving the benefits for my hair and skin too. Rainbow Nutrients’ formula is packed with everything my body needed: biotin, collagen, zinc, and a blend of herbs that support overall beauty from the inside out.

    I highly recommend

    What I appreciate most is the transparency—all ingredients are listed clearly, and there are no hidden fillers, GMOs, or dairy (I’m lactose intolerant, so this was a must). The capsules are plant-based (veggie caps), which fits my dietary preferences, and taking 2 a day with water is effortless—no weird aftertaste or digestive issues.

    very nice

    The supplements are easy to incorporate into my morning routine—2 capsules with my coffee, and I’m good to go. They’re gentle on my stomach.
