Hi Boosted, and welcome to the Vitamin forum.

Your case is quite complicated. The Jevity is a really good product. Have your discussed this with your doctor? Adding on things of your own?

Flax oil would be one way to increase EFAs, is organic, and would provide more calories. I'd ask your doctor how much would be safe for you to use.

I'd also get some testing for Vit D levels, and B12.
Vitamin D in the Jevity is quite low.

Are you expected to get the tube feeding removed? or is it going to be a lifelong thing?

It is really hard separating effects from the brain surgery from nutritional deficits. So don't hesitate to ask the doctors, or consult a nutritionist on your own if you feel that is necessary.

Here is a link with information on nutrient content:

One thing that is missing is antioxidants...flavinoids found in
fruits and veggies. You can ask your doctor if it ok to add in nutritional fruit juices...there are several powdered versions with high ORAC scores.

If you are experiencing loss of muscle mass, you can also ask if whey protein is allowed for you.
