I am a pharmacist by training. The company Solgar very nice to me, especially since a few years ago she appeared on the Russian market, though not in the full range and not iherb-ovsky prices))) Solgar is usually seen in the first place, if my family needed some preparations. Very much, it gives me confidence. Very good combination of price and quality. Oat bran, I try to use all the time. The effect of the use of conventional (loose, not tablets) oat bran I like more. But it's a great "road" alternative - to 2 m, 2 times a day.. And drink a lot to remember, that they swell in the stomach!
