At certain times of the year‚ you sinuses and respiratory system may need a little bit of extra support in order to get through the day. You want to hold off the inconvenience of not feeling at your best‚ but some people also don't want to take too hard of medicine in order to not throw their system off too much. You may instead want to try a dietary supplement. Aller-C 100 capsules from Vital Nutrients contains Quercitin and Hesperidin for normal function of your respiratory system and helpful relief worth believing in.

With an ability to support stable mast cells‚ this supplement also can support proper levels of enzymes as well as physiologic factors that add to balanced sinus function. This comes from the highly physiologically active and useful flavonoids Quercitin and Hesperidin. Quercitin‚ a plant pigment‚ has a role in decreasing histamine production‚ along with antioxidant and possible anti-inflammatory properties. Hesperidin is a bioflavonoid that is primarily found in citrus fruits‚ used to help with blood vessel function and possibly as help against inflammation. This supplement also includes a major source of vitamin C as ascorbic acid‚ and high potency Bromelain‚ which is most effective when taken away from meals.

Vital Nutrients cares about consumer safety and health. This product has been rigorously independently tested for criteria including authenticity‚ potency‚ herbicide and pesticide residue‚ stability and bacteria‚ and yeast and mold counts. It contains no type of coating‚ binders‚ yeast‚ wheat‚ soy protein‚ or preservatives.

      Wipes out my allergy issues

      from Houston TX on 4/30/2020
      I have been taking these for several years on a daily basis, doubling up during my allergy season (which is ragweed) and tripling up when I feel anything upper respiratory going on. It’s allowed me to get off 2 of my daily allergy meds and I’ve recommended it to a LOT of people, have my 11 year old taking it and get sick 1/2 as much as I used to.

      Pros

      I get sick less and take less medication.

      Cons

      Nothing.
      I would recommend this item to a friend.

      Pros

      It is easy to take and helps with my allergies.

      Cons

      The cost.

      Works Great for Cow Protein Sensitivity

      from Bothell WA on 8/13/2018
      My son, who has a cow/goat dairy protein sensitivity, has been using Aller-C by Vital Nutrients for years because of the high amounts of quercetin. This helps him digest cow/goat dairy protein so he doesn't have to worry about food sensitivities when he's eating outside of home: at friend's houses, parties, restaurants. Since he's been using it, he has not had a major reaction when digesting cow/goat dairy protein.

      Pros

      Everything

      Cons

      It's a bit pricey

      from Georgia on 7/02/2018
      I use Aller-C by Vital Nutrients  several days before and during times when I am cleaning out areas where dust has been a long time. This helps tremendously with my allergy to dust mites.

      Pros

      No side effects like other OTC allergy meds.

      Cons

      Can take a few days to get full effect.

      Pros

      Works great!

      Cons

      Nothing.

      I had been using Benadryl much of my life to deal with a number of allergies. Unfortunately after using it for such a long time I had a reaction to Benadryl. Aller-C by Vital Nutrients product has been an effective natural replacement. Thanks!
