Good Maintenance

I have bad allergies in the later summer/fall season and I know the fires don’t help (NorCal). I’m outdoor a lot and have become sensitive to irritants and pollen. I started taking this to help with a cough I get this time of year and it really helped me. I am sure it helps protect me in other areas too. I ordered a bottle for my mom and brother. I’d recommend it! I prefer vitamins over inhalers any day!

Great Supplement for C19

I’ve been taking this supplement since the beginning of the C19 pandemic and have been able to remain healthy even after being exposed. This has essential ingredients that are proven to help boost your immune system and I am very happy with the results so far.
