FAQs
How do I know if ST1 is right for me?
ST1 suits sexually active adults who want a simple, once-a-day way to reinforce their immune defenses against common pathogens. If you prefer a clean-label, vegan capsule that combines antiviral botanicals, immune-support vitamins, probiotics and antifungal ingredients for added peace of mind, ST1 is a good fit.
When should I expect to see benefits?
Most people feel smoother digestion and steadier energy in two to three weeks as the botanicals and probiotics take hold. Noticeably fewer flare-ups or faster recovery usually follow after four to eight weeks of daily use. Keep taking ST1 every day with food, individual results vary.
What kind of benefits can I expect from taking ST1?
Taken daily, ST1 supplies concentrated antivirals, immune support vitamins, probiotics and antifungal botanicals that work together to lower your pathogen load, shorten the duration and frequency of viral flare-ups, support a balanced microbiome for better digestion and comfort, and leave you feeling more protected and confident during intimacy. Results build over consistent use, with digestion and overall wellness improvements often noticed within the first month and flare-up reduction becoming more obvious after four to eight weeks, individual results vary.
What makes ST1 different from other products?
ST1 is the first and only daily capsule that combines clinically dosed antivirals, immune-support vitamins, targeted probiotics, antifungal botanicals and bio-availability boosters in one clean, vegan formula, giving you comprehensive STD-focused protection without juggling multiple bottles. Instead of repackaging a basic multivitamin or single-strain probiotic, we built a four-part defense stack that tackles viral and bacterial load, balances your microbiome, speeds post-flare recovery and strengthens everyday immunity, all concentrated into a single Size 00 capsule. This one-of-a-kind approach means you get a full spectrum defense system that other products simply do not offer, letting you feel protected and confident with one simple daily habit.
What products does ST1 replace?
ST1 rolls the functions of a basic immune multivitamin, a stand-alone probiotic or prebiotic fiber mix, an antiviral herb stack (olive leaf, oregano, garlic), a nighttime antioxidant blend of turmeric, resveratrol and zinc, lysine-based flare-up rescue tablets, plus cranberry or other urinary-tract antifungal support into one clean daily capsule.
What measures do you take to ensure the quality of ST1?
How do I use ST1?
Take one ViraShield AM capsule with breakfast or lunch, one ImmunoCore PM capsule with dinner or right before bed, and one GutGuard Core capsule on an empty stomach or just before you turn in. These three give you round-the-clock frontline defense. When you feel run down, know you have been exposed, or notice a viral flare coming on, keep your regular routine and add one PostViral capsule daily for seven to ten days, then stop once you have fully recovered. Swallow each capsule with a full glass of water, stay consistent day after day, and always check with your healthcare professional if you are pregnant, nursing, under eighteen, or taking prescription medication.
