hi, after she starts eating raw paleolithic diet, she stops taking all kind of supplements for couple of months, the result was bad. without vit C intake, her hands skin becomes very rough and showing some kinds of spots on. after she starts again of vit C, that problem's going away. she has lower back pain way before she started RPD, her medical doctor recommens to take life long calcium supplements and vit D. she can't eat certain leafy green vegetables like kale, broccoli for her thyroid problems. spinach also contains some kinds of toxin. really need to know the right food intake in order to not have these supplements. she can't eat oranges, apples for her leaky gut syndrome. i know that vit D3 is necessary for some people where there is lack of sunlight. one of my family members live in Bangladesh and she gets breast cancer. when she tasts her blood, that clearly shows that she has lack of vit D in her blood. my point is, in east there's so much of sun and people still have problem of having vit D. so, people like my mother, who's actually suffering these all kinds of diseases, has to be very careful.
