Hi everyone, I recently purchased a Krypton Mini Pro and I'm looking for guidance on how to use it effectively to boost my vitamin D levels. My main questions are: - What's the recommended protocol/settings for vitamin D synthesis for Fitzpatrick IV skin type? - How can I calculate the amount of vitamin D produced per minute of exposure with this device? - Are there any specific distance or timing recommendations I should follow given my skin type? For context, I have Fitzpatrick IV skin, so I understand I may need longer exposure times compared to lighter skin types. I'd really appreciate any insights from experienced users or anyone who has data on the vitamin D production rates with this particular model, especially for darker skin tones. Thanks in advance for your help!
