Do probiotics replenish good bacteria?

Yes, probiotics help restore gut flora balance by introducing beneficial live microorganisms that can outcompete bad bacteria, support the gut lining, improve digestion, and replenish good bacteria, especially after disruptions like antibiotics, but they don't permanently colonize and the specific strain matters for specific benefits. They work by producing helpful substances (acids, antimicrobials) and modulating immunity, but a balanced diet rich in fiber remains crucial for long-term gut health.

Which two vitamins should not be taken together?

While many combinations are fine, Vitamin C and B12 should be spaced out as C can hinder B12 absorption, and Iron and Calcium/Zinc compete for absorption, reducing their effectiveness; also, high doses of Zinc and Copper can cause deficiency.
