Hello,
Our Gummies are not specifically adult only. 2 Gummies is an adult dose of 2000IU. If you'd like to administer a dose of 1000 IU, our gummies would be fine. Just only give 1 gummy instead of 2.
I hope this answers your question. Feel free to reach out directly to us if you have any more questions.
Thank you for contacting Lunakai and have a nice day.
Warmly,
Bella D.
