I am 47 yrs old and discovered 5mths ago I am perimenopausal. My symptoms were just horrendous, hot sweats, massive brain fog, irritable, low self-esteem, no motivation, extremely low mood. Hair, nails and skin in terrible condition. I've been taking biotin for the last 3 x months, I've got to say my nails are so strong, and my hair feels a lot fuller and in better condition. I've been taking meno complex and pure collagen for the last 3 x weeks and I can honestly say my brain fog has gone, my mood so much lighter and less anxiety. Expensive supplements, but worth it. Many Thanks R
