I have been using this stuff for years now so this review has true data behind it when it comes to my use. It’s easy to put on since its topical so it helps cut down on the already heavy load of supplements I take. It is super effective. The maker claims the skin is the best place to absorb vitamin D, which makes sense since that is how we get it from the sun. As I have mentioned before, I get my blood tested about every 6 months and prior to using this my vitamin D was low, a very common thing as of late in America. Since using this my vitamin D levels are perfect which I believe have really helped me with my Asthma and not getting sick
The only bad thing I can think of is you have to put it on every day (or at least try to) but that’s how supplements go. Highly recommend this to anyone struggling with their Vitamin D levels or just looking to get that supplemental boost.
