Vitamin D

take it with fat, I take healthy origins, which has a little olive oil added, I take 40,000iu once a week, took my level from 33 to 86.

Just had another vitamin D test and it was 40. I'm still taking 10,000IU daily but had stopped a few weeks before this test. I mega dose fish oil at the same time so I'm probably getting enough fat. Unless the fish oil gel caps don't dissolve fast enough? Don't know how much longer I should take 10,000IU from what I've read you should only take this much for a short period of time.

cant remember all the studies as I have not read them in awhile, but I think overdosing can occur at 40,000iu ed for 3 + months, if someone got toxic it could cause hypercalcemia, I like to take with daily dosing of vit k.

I have finally broken 50 after years of incremental progress on using common caps with soybean oil. This product works. Studies I've read suggest no advantage in taking small daily doses over once per week large doses. Biotech Pharma also produces 1k IU and 5k IU caps of pure powder. No dairy,egg,fish, nuts, wheat,gluten, soy,sugar,yeast or artificial colors.

They offer the 50k caps in quantity of 12 for typical res-ponders. I was taking over 100,000 a week of conventional soy oil pills then the liquid with poor results.
No. Not correct. Oral supplementation of D3, even at 20,000 iu per day will NOT yield normal or high normal serum levels in every case regardless of brand used. I'm a testament to that fact with labs never over 42 (30-100) and it taking four years to get to that point. I'm currently doing 15k ( up from 5k starting) a day of Rx liquid plus now, a 50,000 iu Bio-Tech Parma once per week.

Understanding Your Hormones

Estradiol (E2)

A form of estrogen produced from testosterone. Important for bone health, mood, and libido. Too high can cause side effects; too low can affect well-being.

DHT

Dihydrotestosterone is a potent androgen derived from testosterone. Affects hair growth, prostate health, and masculinization effects.

Free Testosterone

The biologically active form of testosterone not bound to proteins. Directly available for cellular uptake and biological effects.
