Works and Ingredients also have general wellness utility

Works great!

ok here's the thing. If you have mold, mycotoxins or anything else that's not healthy, you may be helped with this product. You can't just buy this on your own though. You need to see a doctor about this.

This works like magic. So glad I found HistaQuel, helps my hives & rashes like nothing else i've tried! Highly recommend!

This is a great product but I stopped buying it because it’s insanely expensive, even for what it is the price is entirely too high. I take vitamin c and a bioavailable form of quercetin from Integrative Therapeutics that works really well.

Works as stated.

From my research, I also found that this company develop products based on clinical research from universities and other places. Look up Tri-fortify and Penn state. Their website list some of the products they sell that were developed this way and I actual found the clinical results from government website. I'm not sure if I can post the link so just look up Tri-fortify and Penn state and "Oral supplementation with liposomal glutathione elevates body stores of glutathione and markers of immune function"Research Nutritionals have a warehouse in Buellton, California and the company has been around since 2006 per LLC lookup and trademarked in 2019. I bring this up again since one reviewer didn't know where they are made. I like that they provide some kind of certificate of analysis, but I would have preferred they provided the actual test results, instead of just their website results without linking the source of the testing company. An example is the expiration on the bottle shows 6/2025, but their website's product lot lookup shows 01/06/2025. You have to take their word that there was a 3rd party test performed. It's just a concern when you see a discrepancy of the expiration date and missing the GMP certification label... makes you wonder if this supplement is made at a GMP certified facility. The pills are easy to swallow...the bottle was double sealed, and you get a 60 day supply as you need to take 2 pills a day. I haven't had any negative effects. I generally take 1 to 2 stars off because they companies don't provide GMP certifications and/or 3rd party test results. Research Nutritionals does provide a semi COA, but the fact that their products are clinically tested...I feel confident in taking their products and they've been around for close to two decades.Side note: I've asked several supplement vendors to provide certificate of analysis and some do while others don't and in the middle are companies like Researched Nutritionals: they take the 3rd party test results and only provide the customers a redacted summary and remove the 3rd party test company to protect or hide certain information they don't want consumer and competitors to see. I don't particular like this as I prefer to see actual 3rd party test results to ensure they are honest company... I can understand why and then I have to go based on how the supplements have affected by body or based on the ingredients provided.

I have MCAS like reactions or MCAS, I've never been told if it is or is just very similar. It has been doing better lately, Cromolyn really helps; but I'd like to take a more natural method if possible. I got this to hopefully help the bladder symptoms, though I don't know if it will. I'd love to be able to eat citrus again. Or I'd love to get off my antihistamine. I'm not sure if that will be doable with this, but I'm down to try.I am familiar with luteolin and fisetin being on an MCAS protocol, but am not as familiar with the other ingredients. That isn't to say they aren't on the protocol, it was a giant list and Idr.As to the lead that someone mentioned, in the state of CA, where this is manufactured, you have to list the prop 65 warning label on anything that comes into contact with potential lead, arsenic , cadmium etc. Every supplement and even most foods you get will qualify as needing this label as natural amounts are found in the soil. That in no way means that this product has lead or is at any greater risk than other companies that do not list this warning. I just have to let you guys know this because I hate when products get poor ratings because people who are not from CA get scared about this warning label. You'll find this label outside every place you go to eat at in CA.This brand is legit. Their website is really helpful if you're trying to look up information related to their supplement and researched evidence. They also have a BBB rating of A+I only gave them a rating of 4 stars for now because I need to try it for longer to know if it is worth the $79. I am in many communities with people who suffer from MCAS and I don't feel right saying 5 stars before I know if it works. However, the quality and credentials of the company does seem 5 stars, so it is worth a try if you can afford it. It may take a few months to update as I bought another supplement from them and want to take it for two weeks without this one to see the before and combined effect of this.As always, ask your doctor, esp if you have MCAS if they think this is a good option for you.
