Vitamin D causing rapid weight loss normal?

Post Reply New Topic

I have been taking less than half the maximum safe dose of Vitamin D since a lab report showed that I had a deficiency. While better mood and better mental functioning have occurred, I've noticed that it seems to be causing rapid weight loss. I was overweight when I started taking it (around 27 BMI) but have dropped to 24 BMI in the course of one month, which is still the upper range of normal, but still scary.

Dosage: around 3000 iu/day, no more than 5000. 10,000 is the maximum safe dosage according to the FDA while some experts recommend 4000 as optimal for someone who doesn't get out in the sun consistently (i.e. me). So what's going on? I was 23 BMI until I started taking Zoloft a year ago, then it shot up over 30, and then wouldn't come off very easily. So is this something to worry about or not? I think I am going to reduce the Vitamin D dosage to 2000/iu per day.

Could Zoloft itself have something to do with Vitamin D deficiency? A Google search suggests that it might.

Hm, I have no definitive answer, but it is interesting. Are you taking D2 or D3? I read that D3 toxicity, which is supposedly much easier to achieve, can seriously suppress appetite. Have you noticed a reduced appetite? If not, it also seems that adequate Vitamin D levels are associated with weight loss...perhaps the previous deficiency resulted in higher fat storage relative to calories consumed and since you started supplementing, the same caloric intake, for whatever reason, is now below your bodies maintenance calorie levels. http://www.medicalnewstoday.com/releases/153669.php How many pounds is that, by the way? ~25? I also read that your body can produce 10,000iu of Vitamin D after just 30 minutes in the sun so perhaps you've briefly reached toxicity after hanging out just a few days in the sun, but I doubt it.

Yeah, that's a substantial amount of weight without having made any significant dietary changes. I guess the best thing to do is see if the weight loss continues. I do think that if it was D toxicity, you'd have to have some other symptoms at this point. I've also read a few bodybuilders post about Zoloft and weight loss but there seemed to also be several who experienced weight gain and none of them had any idea as to why.

My doctor was appalled at my Vitamin D levels (everything else was normal) and so put me on prescription, "catch-up" levels of Vitamin D, which I've been taking over the last few months. I have not lost ounce one. But then I don't typically lose weight without a ton of effort: for example, I didn't lose any weight while I was breastfeeding my kids, either.

I wish I had the prescription on me so that I could read to you exactly what it was.

I haven't noticed any change in mood/cognitive function, either. I've been robbed, I tells ya!
