Many reviewers highlight fast delivery and a customer service team they describe as consistently helpful. Several complaints focus on weak communication, including a website notice about products being removed and missed direct notifications. Usability issues come up repeatedly around subscription terms that make cancellation difficult. Product views are mixed, with praise for effectiveness alongside isolated reports of ingredient or packaging problems.
Examples from available reviews (Nov 2021 – Mar 2026).
Fast delivery and great customer service.
“Fast Delivery + Great Customer Service”
Subscription forces minimum three orders and cannot be cancelled online.
“no way of letting you then cancel your subscription”
All products removed from sale and reviewer questions company status.
“DUE TO UNFORESEEN CIRCUMSTANCES, WE’VE HAD TO TEMPORARILY REMOVE ALL PRODUCTS FROM SALE.”
Reviewer reports poor ingredient quality and improperly milled capsules.
“the ingredients are little better than 'factory sweepings' grade.”
Many high-rating reviews point to quick fulfilment and staff described as friendly and helpful. A smaller group mentions delivery issues and one case where a substitution was refused during a promotion. Comments about easy ordering appear more often than service complaints.
Value complaints show up less often but stand out. One long-term subscriber said a 30% price increase led them to cancel. Another customer reported a discount code that did not work, which lowered value for them.
Many customers describe ordering as easy and the buying process as straightforward. Multiple reviewers say subscription terms block online cancellation until several purchases are completed. These subscription hurdles repeat across negative feedback.
Several reviewers describe steady product quality and beneficial effects, along with fast shipping. Others raise serious quality concerns, including poorly milled capsules and an unsealed pouch. Packaging problems appear less often but are described clearly.
Communication problems come up repeatedly, especially around a site notice saying products were being removed from sale and no personal notification. Other reports mention reorders made without approval and messages that went unanswered. Most negative comments on communication centre on missing replies and unexplained status changes.
Reviews split sharply between many five-star accounts and several one- or two-star complaints about subscriptions, communication, and quality. Positive feedback focuses on responsive staff and fast delivery. Lower ratings centre on broken communication and restrictive subscription rules.
For each review, the core experience based on original source reviews.

The Immune System Boosting Supplements from Twenty First Century Herbs has been a lifesaver for my sister. She was diagnosed with a lung condition and had to take medications that made her very weak and tired. It was getting to the point she was going to give up on my health and do nothing. She tried various supplements but nothing worked until she started using Lungwort Complex and Vitamin C-With Citrus Bioflavonoids. The doctors had done all they could do, the lungs were still not right. A friend of mine told me about First Century Herbs and she decided to give it a try. It has been a month now and she can tell a big difference in her breathing already!
