On March 18, 2026, Chae Ri-na took to Instagram with an urgent update, announcing the final chance to buy Biolectra products. She thanked fans for trusting the brand and laid out a detailed guide on how to take the supplements.
She advised taking calcium, vitamin B12, and vitamin D in the morning; the Immune formula and a vitamin B complex during the day; and magnesium before bed. She emphasized that the Haermes product comes in a powder form, which makes adherence easier.
Saying, "It’s the last day," Chae Ri-na urged fans to hurry and make their purchase. Fan reactions have yet to be confirmed.
