Trusted by My RE – Great for IVF Prep
My reproductive endocrinologist recommended TheraNatal Core for IVF prep, and I’ve been really happy with it. I started taking it a few months before my cycle, and so far my egg retrieval was successful. It’s easy on my stomach, and I like that it includes everything my doctor wanted folate, vitamin D, choline, and more. Definitely a high-quality prenatal I’ll continue using through this journey.

Good value for the price.
Since I have started taking these I feel like I have started to have pregnancy symptoms, nauseous after I take them, certain smells make me want to throw up and I have been more emotional. Aside from that I think it is hard to know if a supplement is doing what it is supposed to or not and it affects everyone so differently. I do think that this is good value for the price, I am not convinced if I would purchase it again or not yet, I have been taking it about a month and a half now.

Would highly recommend for IVF
I saw this brand recommended by other women going through IVF so gave them a try. I was very pleased with them. No fishy taste or weird side effects. I could take these at any time of day and feel fine, though I think it’s always best to take vitamins with food. I am 35, have low egg count, and needed great egg quality for the eggs we did retrieve. I think this definitely supported my egg health. At every stage of the journey my doc was shocked at how well my embryos were doing. Retrieved 18, 15 mature, 12 blastocyst, 6 euploid! Much better than the 2 embryos I was predicted to have with my stats. These vitamins worked great!!! I also took ubiqunol, vitamin d, and fish oil.

Nothing but a bad experience for me
*update after a few months*So I took these for a few months and they caused more issues than they are worth. Every month right after ovulation, my boobs get extremely sore to the point it causes issues in my every day life. I am extremely over emotional a week before getting my period and have gained 8 pounds. I stopped taking them a few weeks ago and this month right before my period I have a yeast infection. I have never had one and nothing has changed. I have so many issues I am going to my doctors to see what can be done to fix this because I believe my hormone levels are off and I have never had problems with that my entire life.Previous update after taking one month.I have been taking these for a little over a month. They are easy to swallow and don’t really have a flavor to them. I am taking them to try to help get pregnant since we have been trying for 19 months now. I do notice my pee is really yellow about an hour or so after taking them so definitely drink lots of fluids if you are going to use these. I also noticed after ovulation (this happened twice), my boobs were extremely sore and get swollen. I have small boobs so it’s very noticeable. I also got very emotional before my first period on them and am very emotional now and I am about to get my period again. Fingers crossed I don’t but this is a last resort for us to get pregnant since our insurance doesn’t cover anything. I will update in a month or so if we have any success

Great Preconception Support with Clean Ingredients
I’ve been using Theralogix TheraNatal Core Preconception Vitamin Supplement for a few weeks now, and I’m very pleased with it so far. I chose this brand because it’s NSF certified, which gives me confidence in its quality and safety.

Cycle regulating
I have felt like my hormones were all over the place. My menstrual cycle had become irregular for the first time in my life. I wanted to have a better idea of my cycle so that I could know my fertility. These vitamins did not help me to get pregnant. However they did regulate my cycle again. They are very easy on your stomach. I was easy to add them to my routine. I wish they were a little less expensive and more constantly in stock.
