High-Dose D3 Boosts Immunity – Best Price Small Capsules!


Review from a health nut friend (I edited), who used my account when she first ordered a few years ago:


This is the only product that sells at high dosage in such a small capsule at the best price.


It's easily absorbed and tasteless. All my capsules have come intact and I've been ordering for two years.


The shipments have been timely.


I've noticed an improvement in my health and immunity (have not caught a cold or the flu) since taking these, even though I eat healthy and exercise regularly.


I've had shortfalls in my Vitamin D3 levels occasionally in the past, according to my blood tests.


I first read about the benefits of high dosage Vitamin D3 from reading self-published books from Amazon.


The below authors recommend that you take Vitamin K to ensure that Vitamin D goes into your bones, instead of calcifying your arteries.


I take Triple Vitamin K in veg capsule form to cover all the bases, as there's a debate on which form of K is best for Vitamin D (from Amazon: "Vitamin K - Triple Play" by Bronson, 180 vegetarian capsules bottle).


Vitamin D is also supposed to help fight colds and viruses.


RECOMMENDED DOSAGE:


The conventional recommended dosage is anywhere from 2,000 iu to 5,000 iu a day.


It's best to take VITAMIN K (Look for the Triple Form) to make sure that Vitamin D goes directly into your bones, and not elsewhere.


WARNINGS:


You must consult with your physician before taking any supplements, as your individual health needs and medications may contradict taking such high dosage Vitamin D3, along with the below authors' other recommendations on additional supplements to take with high dose D3.


Two of the crucial supplements to take are: Magnesium and Potassium, according to the authors, among other recommendations.


You should be aware that Magnesium and/or Potassium and cause stomach upset in some people.


MAGNESIUM: ALTERNATE METHODS TO TAKE TO BYPASS STOMACH:


EPSOM SALTS is said to be an alternate way to avoid ingesting it orally, by soaking in these salts.


Another method is skin application by creme.


Please search engine the above alternate methods for instructions and efficacy.


Since I've haven't tried these methods, I don't know if they may upset the stomach in the end.


You MUST monitor yourself with blood tests when taking any megadoses.


High Vit D dosages can make your Calcium levels too high, which is dangerous and painful, causing heart rhythm problems.


High Vit D doses can also cause electrolyte imbalances.


Make sure that all your blood levels are regularly monitored and normal according to your doctor.

Vitamin Basics & Tips


Vitamin D3 plays a critical role in immune function, bone health, and disease prevention. While sunlight is a natural source, supplementation is often necessary, especially in regions with limited sun exposure. High-dose Vitamin D3 (2,000–50,000 IU daily) requires careful management: pairing it with Vitamin K2 (preferably the "triple" form MK-4, MK-7, and MK-9) ensures calcium is directed to bones, not arteries, reducing calcification risks. Magnesium and potassium are also vital cofactors, aiding D3 metabolism and preventing electrolyte imbalances.


Blood tests are essential to monitor Vitamin D levels, calcium, and electrolytes, as excessive doses can lead to hypercalcemia, heart issues, or kidney strain. Those with deficiencies or chronic illnesses may benefit from protocols like Coimbra’s, which emphasize tailored high-dose D3 under medical supervision. Dietary sources like fatty fish, fortified foods, and egg yolks provide modest D3, but supplements remain key for therapeutic doses. Always consult a physician before starting high-dose regimens, particularly if taking medications or managing conditions like autoimmune disorders.


Alternative magnesium intake methods, such as Epsom salt baths or topical creams, can bypass stomach discomfort. While Vitamin D3 is linked to cold and virus resistance, balance is crucial—prioritize safety through regular testing and holistic nutrient support.
