For millions of people from Broadway to Hollywood and everywhere in between, Wellness Formula has become the “go-to” product for everyday immune support. Whether you are striving to avoid sick days or an athlete looking to add to your performance regime.
POWERFUL ANTIOXIDANT DEFENSE – Antioxidants are a critical component of immune health, as they prevent free radicals from being formed or from causing damage to our immune system protecting white blood cells. Wellness Formula provides key antioxidants such as vitamin C, vitamin A, beta-Carotene and grapeseed to provide antioxidant defense, as well as clinical doses of zinc and copper which are both important ingredients that defend against superoxide radicals.
NATURAL STRESS RESPONSE – As emotional and physiological stresses can significantly impact our immune system, Wellness Formula includes eleutherococcus and astragalus which are adaptogens that support the bodies’ response to stress and fuel the immune system. Wellness Formula provides your body the defense to keep you able to meet stressful deadlines, run a busy household or travel the world!
COMPLEX IMMUNE DEFENSE – Wellness Formula provides clinical doses of key nutrients vitamin A, beta-carotene, vitamin D, and zinc to support a healthy immune system. This formula includes garlic bulb and propolis, which have a long history of traditional use as immune system boosters. It also contains several immune support ingredients rooted in traditional medicine: Echinacea, elderberry, and horehound are included to enhance immune function, and astragalus and isatis leaf and root provide immune system support.
RESPIRATORY SYSTEM SUPPORT – Mucous membrane function is an important aspect of the immune system, and Wellness Formula provides several ingredients to help it function during times of imbalance. Combines a high potency source of vitamin A, necessary for maintaining nasal passages and the keeping mucous membranes moist and functioning. Wellness Formula keeps you breathing easy by providing mullein, horehound, and polygonatum which support respiratory function.

Excellent product with very strong garlic odor that lasts
Excellent product with very strong garlic odor that emanates from your skin and lasts for days even after showering. It contains many “alternative health items.” Expensive product but it is cheap compared to what you would pay to buy each item individually. Effective in managing “allergies, asthma, colds and flu.” Not a cure, but helpful to manage symptoms. I work part time so the odor doesn’t bother me on days I don’t work. I go off 2 days before work and I stay off until I have another 4 days off. Has used this product for years with good results, but may not be for everyone.

Okay, so this does work.
My chiropractor recommended this to me as a way to boost my immune system. I have definitely taken it consistently and as directed at the very hint of a cold, and I’ve ended up getting sinus infections and bronchitis just as usual over the previous months. Instead of this, I would recommend drinking a lot of water, taking a multivitamin, eating a healthy diet, getting plenty of sleep, and eliminating as much stress from your life as possible. That’ll probably be the real trick to health — not just a weird smelling little pill.UPDATE (5/12):My husband and child were both extremely ill over the past week. My husband was the sickest he’s ever been in his life. I took six pills (plus some echinacea tea) the day I felt the sore throat coming on. I DID get sick, but I only got a cough — no fever, no blistering in the throat, no vomiting, no rash. I am a convert.SECOND UPDATE (11/12):I have a crap immune system. I had shingles in Sept, followed by a kidney infection in October. Horrible! I started taking these again (two in the morning, two in the evening) while I had the kidney infection. My husband and two year old son got a horrible cold and cough, and my husband got bronchitis from it. The little one got ANOTHER cold. Since I’ve been consistent with taking it, I have not gotten either cold. I also had a small shingles rupture on my finger this morning and took six pills today. It is now gone. (I have had shingles twice this year; I’m a freak of nature.)I’m now a real believer in this stuff. Seriously I am. And I don’t believe in many herbal remedy type things. I take a vitamin and fish oil. And this stuff.The ingredients SEEM to work. And they’re not so weird — lots of garlic, echinacea, astralagus … stuff that’s pretty commonly seen as immune boosters.I may not be a double-blind study, but I can swear that this stuff works — at the very least to prevent upper respiratory infections.

Perfect addition for the health cabinet
One of those items I always keep in on hand! I’ve been using this product for years and am continuously amazed at how well it works for a variety of aliments. I find it Extremely useful for any kind of skin infection! The first time I tired it for that I had a cat bite that had started getting a little streaky and I could tell there was pus filling up deep inside, since it was a weekend I didn’t want to go to the emergency room so I started this hoping I could hold out till monday and see my regular physician. By the next morning the redness was dramatically reduced and the swelling was down to just the immediate puncture site. By monday morning I didn’t feel it needed seeing by anyone and within the week it was completely healed over. Now I am Not telling anyone to use this in place of a medical emergency or to self treat, etc, etc… just retelling my own experience.I can also state from experience that my family has held off all range of sicky bugs. And with two children in school, myself working in a public gym and husband as a salesman working with the general public, that’s saying something! No one has had anything significant last more than a day or two in years and nothing that has required a medical visit as long as we start with this at the first sign of anything.Oh, one more thing to add; if you have trouble swallowing large pills, go with the capsules they are much more tolerable. And I rarely take the suggested amount. 2 capsules every few hours seems sufficient for me and 1 every few for the kids is plenty.

Best vitamins ever
Best vitamins. Take when I feel I am getting sick and causes me to not get sick and decrease all symptoms

Good for keeping you healthy
This really works if you feel like you are catching a cold or coming down with a bug. We like the capsules better than the tablets for ease of swallowing. We have told our family and friends about Wellness and they now use it too.

For me it’s almost a cure all
As soon as I see someone near me is sick that I have to be around I start taking this and I either don’t get sick at all or have a very mild case compared to them. Recommend but fyi, it tastes awful.
