Sis, nakikita ko na may overlap ang NATA-4 mo at Caltrate, especially sa calcium, magnesium, zinc, at copper, kaya mukhang mahirap i-combine nang buo without going over the safe daily limits, lalo na yung calcium at magnesium na mataas sa Caltrate pa lang. A few of us moms learned the hard way na ang dami ng supplements ay hindi laging better, at pwedeng maging problema pa with absorption! Best talaga na i-check mo ito with your OB or doctor kasi sila ang makakasabi kung kailangan mo pa ng additional calcium or kung sapat na ang NATA-4, para walang harmful overdose, mas naka-peace of mind ka rin.
