Yes, great fat from healthy animals taste really good.
Especially when you are very hungry.
Glad you are enjoying it!

There is an extensive thread on high meat called High-Meat-Recipe Preparation For More Advanced RAFers.

Follow the directions and you won't get sick. Well so it seems. I had my first high meat yesterday and some more for breakfast this morning. I got impatient for the stuff in my fridge so put some in a jar and left it room temperature for 3 day's.

None of my high meat smells too bad as far as I can tell. If you make a small amount at room temperature you might be able to eat it before the smell gets too bad. Or there is something wrong with my sense of smell, but I don't think there is.

In my country we have red tide alerts.

I squeeze drops of lemon or dunk it in some apple cider vinegar or any vinegar for that feel of cleanliness.

Your taste buds are your friend.  If it stinks or tastes bad or tastes dirty individually, spit it out.

I eat oysters individually so I can taste them if they are good or not.

In our markets when they sell oysters in their shell, it is understood they are ALIVE, do not buy them in the shell dead.

Do not "clean" live oyster outer shells by scrubbing out the mud, they get nutrition there that keeps them alive.

Eat immediately while they are alive, don't let them die on you.

FYI I eat oysters on a regular basis, once or twice a week.  They are relatively cheap where I live.

I've felt very good when I took Rosita. I'm ordering another bottle with the intent to make sure my Vitamin D is good. Back in the day I felt fantastic using a fermented cod liver oil and then they started tasting wrong to me. I had to stop it. If you listen to your body in an Instincto manner it will help you make the right choices after highly addictive substances like refined sugar are removed.

Here is an interesting video I came across recently which speaks strongly to having enough vitamin D, preferably from sunlight (which is not always practical), as well as sufficient B vitamins and deep sleep. It's all intertwined with gut health. It's about 90 minutes but makes some great points and is changing my approach right now as far as my current health recovery.

As far as foods you can use oily fish, liver, or quality egg yolks.
You need to make sure you get enough of the co-factors. Vitamin K. Calcium. Zinc. Magnesium. Boron. Vitamin A.

It's possible if you are low in the co-factors your body would have high circulating calcium and the body would reduce production of vitamin D to protect itself. I'd start with looking at vitamin K intake and move on from there. You may find you need to consider some greens if you are eating omnivorous. I'd caution against high oxalate greens like spinach and kale. See how you do with things like collards, turnip greens, or mustard greens.

Vitamin D supplements are not the same substance as Vitamin D in animal products.  I don't take any supplements and don't believe that they are helpful, probably toxic if anything.

I get into the sun as much as I can, even if it is a few minutes at a time on the face and in the eyes, and find a warm spot up against a big wall in the sun.  Remove my shirt if possible even for a few minutes. 

I also eat raw animal products like milk, butter, cheese, meats.  D is in there.  I feel fine in the winter now and used to suffer from it.

I can't really give you advice, as I'm still on a healing path, but I can give a different perspective.  I have basically all European ancestry. I've had vitamin D deficiency twice, confirmed by bloodwork.  Despite being put on high, therapeutic doses of vitamin D, I did not feel any significant difference. I've also taken vitamin D3 supplements on my own and never felt any difference.

Given my ancestry, I am wondering if the "optimal" vitamin D range is even valid for me. Obviously my European ancestors would not risk frostbite and hypothermia in order to sit around naked in the snowy winters so that they can catch what little bit of sun may peak through the dark grey winter clouds.

So, whatever you can get through food is probably ok. I would consider what kind of climate your ancestors lived in and how they may have gotten vitamin D. Of course, humans do evolve with their environment, so if you live in a very sunny climate it may be better to get sun (animals in sunny climates may not have as much fat stores and thus less vitamin D).
