    Please tell me how vitamin D supplementation has caused calcium deficiency, let's discuss.

    I just had a thought, what if overdosing on vitamin D initially after starting carnivore red meat = lot of iron (Ironman) led to excessive iron absorption and with calcium competing with iron, forced calcium of through the kidneys further exacerbating iron absorption and vitamin D compounding...

    Please tell me how vitamin D supplementation has caused calcium deficiency, let's discuss.

    I just ate 6 eggs and eyes burn, skin burns. Skin can turn red. Feel groggy and sleepy. I feel high. Sometimes taking calcium helps, but only one or twice then no affect. Sometimes taking vitamin K helps, then no affect after that. I had the same problems with diabetes drugs, a one time...

    Please tell me how vitamin D supplementation has caused calcium deficiency, let's discuss.

    I figured it out. I had been on 2000 units vitamin D for a year before starting carnivore, no issues, 24 level. A week after starting carnivore I gradually started having these issues. I simply became more sensitive to vitamin D and vitamin C due to normal glucose. I tried mag, made the problem...

    Diminished sexual function after starting TRT

    I've been on TRT on and off for 10 years, on the longest for solid 6 years, came off and HPTA rebooted very quickly, within 4.5 weeks after stopping injections and 7 days on short acting oral testosterone. Permanent atrophy is unlikely.

    Diminished sexual function after starting TRT

    AI's can't affect estrogen produced within the testicles, Ai's only affect E2 outside the testicle environment. Some men have struggled to lower estrogen while on hCG.

    Diminished sexual function after starting TRT

    Hard to tell if your T levels are actually on a steady decline over this period of time. Many things contribute to T production, diet, sleep and even overtraining which will effect T negatively. Your hormones are constantly changing day to day, you'll never repeat the same test twice, because...

    Diminished sexual function after starting TRT

    The cause is hCG, which is common to see sexual function degrade in some men. The LH receptors weren't meant to be stimulated in a near constant state, LH receptors are meant for pulsatile stimulation. The half-life of LH is 20 minutes, the half-life of hCG is 24-36 hours. Big difference! Some...

    Maximum hematocrit recommended with positive calcium score

    If you want to significantly lower or desire zero CAC scores, look no further than the carnivore diet. If you're worried about cholesterol, get this out of you're head! Sugar damages the endothelial walls of the arteries and LDL gets stuck to the arteries. Sugar attaches to proteins and lipids...

    Please tell me how vitamin D supplementation has caused calcium deficiency, let's discuss.

    I have developed calcium deficiency supplementing vitamin D, the higher the dose, the worse the deficiency. I'm trying to figure out how to solve this without having to supplement calcium which is a big no no! Without calcium supplement, vitamin D causes excess urination which leads to...

    Bloodwork Results - Thinking About Starting TRT

    I had been on TRT for almost 8 years on and off, came off twice and recovered fertility quickly and I'm 24 years older than you. If you take too much zinc, this could act as a aromatase inhibitor and decrease estrogen. You would have to be hyper sensitive to zinc for this to happen. I don't...

    Bloodwork Results - Thinking About Starting TRT

    The normal ranges have nothing to do with quality of life. Each case is unique, not everyone fits into the same box. Typically people with diseases will be at the bottom 25 percentile, excluding outliers. You should probably sit this one out and start taking notes...

    How long does testosterone drop after stopping

    Once every two weeks isn't recommended, suggest you ditch the clueless doctor. This protocol will create large swings in hormones and you'll lack a consistent hormone profile. Also these protocols tend to increase risks of high RBC and hematocrit further complicating treatment. 200 mg every two...

    TRT Peaks and troughs or steady levels. Which is correct?

    I only responded to oral testosterone. Turns out I didn’t need it. My original health problem was T2 diabetes, which caused iron and vitamin D deficiency. The treatment was TRT! I don’t know how TRT is supposed to correct iron and vitamin D deficiency. If anything, TRT is going make the iron...

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.
