You sure can record your vitamins. Use the Create Foods (on the left side of the webpage) feature to set up food for your vitamins. Once set up, you can click on the your vitamins by looking at "Recent Foods".
All I can say is that I'd like to include my supplements, also. I used FitDay about 2 years ago, and it seemed easier to use back then. Then when I created a custom food, I could specify the the serving size as whatever measurement I needed, not just as "1 serving". Also I think they included more of the vitamins and minerals. Sometimes software upgrades aren't improvements.
I've created my multivitamin in custom foods, but for some reason you cannot indicate the levels of all vitamins and minerals in the custom food editor. My multivitamin contains pantothenic acid (vitamin B5), but I can't add it to my custom multivitamin, so it's now showing up as a deficiency in my diet :-/
There are quite a few other things in the multivitamin I can't include either, such as vitamin K, iodine and chromium.
Omega III Oils--no way to create a custom food for these supplements
I take fish oils daily for health, and have tried to create a custom food for the fish oils. There is no space to enter on a custom food "Omega-3", or the amount of EPA to DHA to Other Omega-3's.
Also, this fish oil has Vitamin E (d-alpha tocopherol), and while I was able to add "100%" of rda, when I look at the detailed rda list, I see that this value is actually in the wrong place, yet there's no way for me to enter it correctly.
FITDAY!!! come on! Omega-3's are a critical part of health, and weight loss. Help us log this!
