One of the problems with vitamins A and D is its hard to get them in the right ratio so it doesn’t throw your body out of whack. Thats why its good to get a natural source of vitamins A and D which has them in the correct ratios (4:1). A great source of vitamins A and D is fermented cod liver oil which not only is anti-inflammatory, but it also (supposedly) destroys biofilms, and has prebiotic properties. There is only one brand that creates them in the correct ratio and it is the blue ice royal brand.
Just thought I’d mention it!
