Rated 5 out of 5 by from Finally Relief My husband was currently on steroids for asthma and suffering badly from bad allergies and sinus trouble,living on prescription medication.. not being able to sleep comfortably etc... I ordered Clear Day and he took two capsules as suggested...30 minutes later he felt the sinus pressure start to relieve its self and sinuses opened up and he could breathe through his nose again! It was day and night! He took 2 more 4 hours later and actually had an undisturbed nights sleep. Excellent product and we will be buying this again!

Rated 1 out of 5 by from Gave it a try, but did not help my allergies I was hopeful as I don't like taking the standard pharmaceutical offerings and have great success with Hammer products, but after a using the entire of bottle of Clear Day I can say honestly that it did not offer me the desired allergy relief. I will be likely contacting them for a credit soon.

Rated 5 out of 5 by from No more itching! For the last several years I have gotten itchy skin due to allergies. Nothing I took gave me any relief. From my first dose of Clear Day I was hooked. For the first time in years I am itch-free!

Rated 5 out of 5 by from I survived epic tree pollen using just this. I have lived in the South for 16 years and we are having/have had the worst pollen season I can remember. My allergies are bad and I have to take allergy pills year round because my work has me outside a lot, not to mention my training. Two weeks ago at the height of the pollen falling I went off the allergy pills completely and have been using Clear Day exclusively every 4 hours or so during the day. It actually works better. I can now breathe at night and so I'm sleeping way better, in addition to not sneezing, watery eyes, runny nose and the rest of that fun stuff that the allergy pills did help with.

Rated 5 out of 5 by from off the hook i would like to say hammer nutrition is by far the "Best" Being a first time buyer they made it so easy to order the Clear Day and Nasol .shipping was great had it in a couple of days. I have very bad Allergy's my nose is always clogged up and when i started to use both products i was 90% better in just a couple of days .Can't tell you how good it feels to be able to talk to someone and they can understand me.Would tell anybody with Allergy's to try these products they are off the hook.Thank you Hammer Nutrition

Rated 5 out of 5 by from Works great- I was skeptical at first, that Clear Day would work. I have been using OTC products for years due to allergies. After the first day, using up to 4 capsules, I could tell there was a difference. Highly recommend.

Rated 5 out of 5 by from Clear Day makes the ride better! I just started using these a month ago now that spring has arrived. One of my issues during a ride is my allergies going crazy, really doesn't allow me to enjoy riding. I have been using these as directed for a few rides now and they work great, my allergies are no longer interfering with my rides! Happy Nose!

Rated 5 out of 5 by from Hammer comes through once again! I have used other Hammer products for years (electrolyte tabs, sustained energy powder, gel) then along comes Clear Day just when I was really at my wits end with wicked allergy symptoms! Knowing that Hammer really does the "science", I had a good feeling that this would be helpful, and wow was it ever! Sneezing attacks and congestion in the middle of the night...gone! Eyes still a little watery, but I can deal with that. What a great product, and great relief. Also happy to not be using OTC drugs any more
