If glutathione whitens your skin, is that good or bad? | Masterjohn Q&A Files #294
Short Answer: Measure this against whether it increases your likelihood of burning. If it does, it’s probably a bad thing, but if it doesn’t, or if it lowers your risk of burning, that’s a good thing. Watch the video or listen to the podcast with the links below.

Vitamin D supplements, testing, and interactions with the vaccine. | Masterjohn Q&A Files #293
Short Answer: Vaccination shouldn’t change the vitamin D requirement. Quarterly testing makes sense for someone who has never tested before or who wants to make sure they stay in range during COVID, but generally testing yearly around the mid-point of seasonality for you, once you know your variation, is plenty.

BH4 vs tyrosine for low neurotransmitters and a high phenylalanine-to-tyrosine ratio. | Masterjohn Q&A Files #292
Short Answer: BH4 is expensive and requires very high doses, so if the problem is modest it can much more easily be solved by taking tyrosine.
