haidut said:I'll have to check. I think the restrictions are based on dose, so getting it into a higher dose in a topical product may be considered a drug.
A few suggestions Haidut:
1) Magnesium product
This is an underrated and under-talked about supplement here but it's one of the most important minerals that Ray Peat recommends. There's nothing amazing or great on the market right now (there's dubious suppliers of real, effective magnesium) and it's extra important to take enough magnesium if you're on thyroid. There's a quote where Peat recommends up to a 1g a day.
2) Caffeine shampoo
There's studies showing caffeine actually works for hair loss yet there's nothing on the market that's pure and free of nasty chemicals and additives.
3) Zinc oxide sunscreen
These three make a lot of sense to me to be added to your range. Pretty much all your supps are something you would find down a vitamin aisle at the supermarket and and the latter two especially would make for great products in the beauty category.
