Start your day with a little sunshine—whatever the weather. The HELLO SUNSHINE Vitamin D3 Patch - Black Sun Symbols delivers a precise daily dose of vitamin D3 and K2 in a discreet, easy-to-use patch. Vitamin D3 helps your body absorb calcium and phosphorus, supporting the maintenance of normal bones and muscle function, while also contributing to the normal function of your immune system. Vitamin K2 works alongside D3 to help maintain normal bones and support normal blood clotting. The patch provides a gentle, sustained release over 8 to 12 hours, so you can enjoy consistent absorption throughout your day—no tablets or drops needed.

Each pack contains 36 mini patches (a full month’s supply, plus 6 to share), each featuring a sleek black sun symbol on a clear, 100% recycled PET backing. With Barriere, supporting your wellbeing is as easy as peel, stick, and go—wherever life takes you.

Unlike traditional oral supplements, the HELLO SUNSHINE Vitamin D3 Patch uses transdermal delivery to increase vitamin absorption directly through the skin into the bloodstream. This method ensures optimal and efficient absorption, bypassing the digestive system and delivering sustained benefits over 8 to 12 hours. Each patch is formulated with 100% plant-powered ingredients, making it vegan, cruelty-free, water-resistant, hypoallergenic, and free from latex and parabens. A third-party-conducted, randomised parallel pilot trial demonstrated that the patch effectively reduced vitamin D3 deficiency, with levels dropping from 23% to 0% after just 8 weeks. With no fillers or questionable ingredients, just one patch a day provides the vitamins your body needs, offering a convenient and effective solution for improved health.

Barrière, founded by Cleo Davis-Urman and Alexa Adams, was born from a personal need for a better supplement solution. After Cleo discovered that traditional capsules lost much of their potency during digestion, she set out to create an alternative that delivered real results without irritation or inconvenience. Barrière’s plant-powered, vegan patches offer effective vitamin support without unnecessary additives. Designed to make wellness simple and enjoyable, these patches provide your body with exactly what it needs, helping you stay healthy and strong with ease.
