I continue to buy BioShield MD (Targeted Immune Support supplement). I believe this supplement helped my immune response improve during the COVID-19 era (starting 8/7/2022). I rarely get a common cold after using this immunity support for about 3 months. After the 2nd COVID vaccine update, I ceased taking COVID vaccines -- because I did not trust the efficacy of the vaccine, and because I was finding my immunity substantially improved by routinely taking the BioShield MD supplement. I have reduced my BioShield MD dosage to 1/2 their recommended dosage, which means I take 1 pill per day. I also take Vitamin C with rose hips. I find their website very difficult to navigate -- though it is better than it was in 2022. It seems that they will not spend enough on their website to make it reliable -- though I am able to login with the same credentials for 3 1/2 years. Also, their pricing is annoying. I buy 6 bottles at a time (once a year) to save money. But the pricing for 6 bottles, which started at $160.38, has remained about $30 higher after that first order.

Thank you so much for sharing your thoughtful review and for being a long-time BioShield MD customer since 2022. We truly appreciate the time you took to share your experience. It’s wonderful to hear that BioShield MD has become a consistent part of your wellness routine and that you’ve personally noticed improvements in how your immune system responds. Many customers choose BioShield MD specifically to help support a strong, balanced immune system year-round, so it’s encouraging to hear that it has been helpful for you. Pairing it with Vitamin C and adjusting the dosage to what works best for your routine is a great example of how people personalize their wellness approach. We’re also grateful for your honest feedback about the website. While we’re glad to hear it has improved since 2022, we absolutely understand how frustrating it can be when navigation isn’t as smooth as it should be. Our team is continually working on improving the reliability and user experience of the site, and feedback like yours helps us prioritize where to make those improvements. Regarding pricing, we completely understand how that difference may have seemed confusing. We want to reassure you that the price of BioShield MD itself has never been increased. From time to time, we run special promotional offers for new or returning customers, which is why your very first order may have been at a lower promotional rate. Outside of those limited-time promotions, the standard bundle pricing has remained consistent. For reference, the 6-bottle bundle currently brings the cost down significantly per bottle compared to purchasing individually, which is why many customers choose that option to maintain their immune support routine throughout the year. Most importantly, we truly appreciate your continued trust in BioShield MD over the past several years. Supporting your immune health consistently over time is where supplements like this can make the biggest difference, and we’re honored to be part of your daily wellness routine. If there’s ever anything we can do to make your experience easier, whether that’s helping with the website, reviewing your order options, or answering questions, our team would be more than happy to help. Thank you again for being part of the BioShield MD community. Your feedback truly helps us continue improving while supporting customers like you on their journey toward stronger everyday wellness.

I have been taking Reactivate, which has made my face look years younger. I take Flora Thin pills which have allowed me to have bowel movements everyday, yeah👍 My hair was shedding like crazy so I now take Rejuva Tress and my hair has stopped shedding and is healthier. The customer service at Suncoast Sciences is absolutely awesome, they are so wonderful to talk with and are very helpful and they have helped to guide me to take my supplements properly. I also use Dermabrite MD which is fading my dark spots and I am also using Total Package Serum which has improved my facial skin. I just love this company! Suncoast Sciences is the best company to deal with with the most amazing products

Sun Coast Sciences LLC has excellent customer support. I had been waiting for my shipment and called inquiring about delivery. I spoke with Jessy and then Giovanni. Both were kind and thorough and answered all my questions. These reps went above and beyond to assure me my shipment would arrive the following day. I was grateful for the kindness shown by both reps. I'm a fan!

I love the Sun Coast products! The Serum makes my skin so soft and is super gentle on sensitive skin. And when I accidentally hit the subscribe button for monthly deliveries, their cancellation process was FAST and super simple! I was shocked how easy it was to cancel but still order the products I wanted. Most companies make it almost impossible to cancel. EXCELLENT customer service!
