I'm already taking a separate multivitamin and multimineral capsule that also contains ginger and green tea extract - is it okay to take a Calcium + Magnesium Hydroxide + Vitamin B12 + Vitamin D3 + Vitamin K2 + Zinc Tablet alongside it?

Smart to check before combining two supplements, since overlapping ingredients can add up to more than you actually need. This tablet is calcium and bone-health focused, with added B12, Vitamin D3, K2 and zinc, so if your other multivitamin also has some of the same minerals, especially zinc or calcium, you could end up going over the recommended daily amounts. Show both labels to your doctor or pharmacist so they can check for overlap and tell you whether to take both, adjust the dose, or space them out.
