What daily natural vitamin supplements help strengthen the immune system?
I was recently told by a doctor that I have a generally weak immune system… I have the immune system of an elementary school kid. 
I am eighteen years old and I oppose taking pharmaceutical drugs whenever possible so can anyone suggest natural supplements that would help prevent sickness and help strengthen my immune system?
There are several aspects to the immune system. 75% to 80% of your immunity comes from the intestinal flora. Most people in America have very poor intestinal flora. Building up these bacteria takes time and is very important part of making your immune system strong. Antibiotics destroy these bacteria and just one antibiotic pill kills most of them. A healthy person should have about 3 pounds of these bacteria in their gut. Eating lots of fermented foods and making fermented foods like homemade kefir from RAW milk derived from grass feeding dairy cows is an excellent way to build those bacteria.
Generating a good supply of nucleotides in the peyer’s patches of your small intestine is another very important thing to do. Any infection, injury, etc. will use up these guys very fast and replacing these is easy to do with good supplementation.
AVOID ALL supplements that have Magnesium Stearate in them. This is an immune suppressant and is found in most pills you buy in stores. BAD NEWS garbage. AVOID all supplements or fortified foods that use Ascorbic Acid as vitamin C. Ascorbic acid that is called vitamin C by many is not really vitamin C, but a component of the true vitamin C complex. Vitamin C was discovered by the Nobel Prize laureate, Dr. Albert Szent-Georgi in 1937. As part of his research on vitamin C, he found that he could not cure scurvy with the isolated ascorbic acid as a single element.
The complete complex of vitamin C includes ascorbic acid and contains ascorbinogen, bioflavonoids, rutin, tyrosinase, Factor J, Factor K, and Factor P. In addition, mineral co-factors must be available in proper amounts. If any of these parts are missing, there is no vitamin C, no vitamin activity. When some of them are present, the body will draw on its own stores to make up the differences, so that the whole vitamin complex may be present. Provided that all other conditions and co-factors are present, the vitamin activity will take place. Ascorbic acid is described merely as the "antioxidant wrapper" portion of vitamin C; ascorbic acid protects the functional parts of the vitamin from rapid oxidation or breakdown.
Check your vitamin D3 level of your blood. It should be between 50 – 60 nanograms per deciliter. This will greatly improve your body’s ability to ward off diseases. Most Americans are severely deficient in this vitamin. Statistically, you will reduce your chances of getting cancer and the flu by 75% with adequate vitamin d3 in your blood.
Getting good sleep is very important. Reducing the sugar and carbs in your diet to 75 grams per day and increasing consumption of good fats is very important.
The most important thing is to make sure you are getting good minerals in your diet. This is extremely hard in the U.S. today due to poor agricultural farming techniques using chemical fertilizers and insecticides. This has literally destroyed the food supply and we have now lost 50% of the antioxidants in the last 25 years in our food supply.
Good luck to you
Vitamin C is the best.
Specifically Ester C.
1 tablet is good for 24h, and won’t bother your stomach.
Some people like echinacea, but that has the potential to negatively interact with other medications.
Jamieson Brand of vitamines. Get a multi vitamin/mineral supplement. Also pick up a bottle of "Stress Vitamines" (all your B components). Take your stress mid-day. Take your multi anytime but ensure u have had something in your tummy.
Your body does not store vitamines B & C…unlike other vitamines, your body takes it as it needs it.
B & C is very quickly absorbed & used up by your body.
Stay away from synthetic vitamines such as One-A-Day etc….go natural, no preservatives, fillers, sugar or junk.
Good luck
You will notice that the only ones who have studied and practiced actually rebuilding and the art of healing the body are not the prationers of medicine as you know it, YOur doctor is taught in how to use drugs, because s/he is completely dependant on the big pharmaceutical companies to do their jobs. which they fail at daily when it comes to healing
This site is ripe with trolls who trash anything healing that doesnt have to do with the medical protocol……….pretending it is healing.
So , if you want to know how to heal yourself and rebuild your autoimmune system, look elsewhere for your answers,
becasue they have trashed this section for a long time……
they dont have anything better to do with their time, certainly not healing.
look into naturopathic doctors, traditional chinese medicine , and the like. they will help you rebuild. nutrionist dearpharmacist.com
Vitamin D is crucial to activating our immune defenses. Without sufficient vitamin D, the killer cells of the immune system called T cells will not be able to react to and fight off serious infections in the body. A 25 hydroxyvitamin D serum level should be around 70ng/ml or 175 nmol/l and it is recommended to take 5000IU of vitamin D daily for good health. Please have a test for 25 hydroxyvitamin D and ask for your blood test results. If your calcium levels are low, you will not be able to absorb vitamin D. If your vitamin D levels are low, you will not be able to absorb calcium. Also magnesium is needed in good supply. Calcium needs magnesium in order to assimilate into the body.
A vitamin D deficiency has shown to cause cancer, colds, influenza, fractures, broken bones, osteoporosis, ricketts, diabetes, chronic pain, fibromyalgia, hypertension, arthritis, depression, MS and other autoimmune diseases, inflammatory bowel disease, schizophrenia, obesity, PMS, Crohns Disease, muscle weakness, muscle wasting, birth defects, periodontal diseases, chronic fatigue, irritability, headache, migraine, brittle nails, dizziness, is associated with high blood pressure and tuberculosis, linked to asthma and may be a risk factor in strokes/heart disease.
