Effectiveness
How Natazia Affects PatientsEstrogen has powerful effects on the body, and works by attaching to certain receptors in the breasts, uterus, ovaries, skin, prostate, bone, fat and brain. These receptors are known as Estrogen Receptor Alpha (ERα) and Estrogen Receptor Beta (ERβ). Estrogen also attaches to a newly recognized receptor called G Protein-coupled Estrogen Receptor (GPER), which is responsible for its fast-acting effects.
How Natazia works in the bodyEstradiol is a hormone that binds to receptors in certain cells and organs, such as the female reproductive organs and breasts. When it binds to these receptors, it triggers the production of certain proteins. These proteins help to regulate processes like the production of other hormones and sex-binding proteins. This process helps to reverse some of the symptoms of menopause, which are caused by a decrease in estrogen.

Natazia Reviews: What are patients saying about Natazia?
5Patient Review
2/13/2015 This pill has been great for me. I was on Yasmin for three years and made the switch to this one. So far, I've lost weight and find that it's much more accurate than the last pill I was taking. Plus, I get my period on the first placebo pill with no cramping!
5Patient Review
2/22/2016 This pill has truly been a life-changer for me. I no longer have to worry about heavy periods or leakage, and my sex drive has increased.
5Patient Review
1/31/2018 I've tried a lot of different birth controls, and this is by far the best one I've used. There are no negative side effects like there are with other hormone-based options.
5Patient Review
6/11/2015 Prior to taking Natazia, I was on Junel Fe. Unfortunately, that led to me having really bad yeast infections and BV. Thankfully, my gyno switched me over to this medication and I haven't had any problems since! Not only that, but I also don't get my period anymore. This has been a total life-saver for me.
5Patient Review
7/11/2016 This small pill has made a big difference in my life. My periods used to last for 10 days and be very painful, with migraines, but now they only last for 2 days (sometimes even less) and the cramps are much less severe. I haven't had any major side effects either, which is great.
5Patient Review
5/5/2016 This is the best treatment I've found for PCOS in terms of controlling my periods, cramps, and some hormones.
5Patient Review
11/21/2014 I cannot recommend this BC enough. It has completely changed my life for the better by essentially getting rid of my period. I also don't have to worry about any mood swings, cramps, weight gain, or side effects.
4.7Patient Review
8/31/2014 I've been using Natazia for a little over two years now and it's helped me out a lot. Not only did it help clear up my acne, but I also haven't gotten pregnant while using it. The downside is that it made me gain fifteen pounds and my breasts went up one or two sizes (C-D/DD), but the positives outweigh the negatives in my opinion.
4Patient Review
2/17/2015 Good birth control pill, though it did cause some vaginal dryness. I only experienced this on the days when I was taking the two white pills. Another issue I had was that, if I missed a pill, I would lightly bleed for nine days straight. This happened to me twice. Luckily, I haven't had any problems since then because I am very good about taking them as prescribed. Additionally, my sex drive decreased slightly during the second and third week of taking this medication.
4Patient Review
11/24/2014 I've lost 13 pounds in the two months since I started taking Natazia.
3.3Patient Review
8/26/2015 Since I started taking Natazia, my periods have been lighter and shorter. However, I've gained 40lbs, have a headache every day, mood swings and low sex drive. After I complete this pack, I will change. Emotionally, I feel as if I have lost control and the headaches takes away from my quality of life--in addition to the other issues mentioned.
