Vitamin Guru's help please!!

I am thinking of switching vitamins not due to labs as i have not had any yet until June but due to the fact that i am taking 2 at a time and i think they are part of my constipation issues having the calcium and iron combined. I bought some bariatric celebrate vitamins today i was on fusion. I bought the multivitamin and then iron and sublingual b12 i also have a bag of bariatric advantage calcium chews. So i am wondering how i space these so i can make the change and see if i notice a difference. Can anyone help me?

I posted my schedule and Kelly approved it a few days ago. Here it is. I had the celebrate calcium chews and couldn't stand them so I switched to bariatric advantage and those are really pretty tasty or as tasty as calcium can get...
I know the calcium has to be spaced out during the day, iron must be taken 2 to 3 hours away from calcium and is best taken with vitamin c to boost absorption.

So......

8 am - bariatric advantage multi chewable orange flavor
bariatric advantage calcium citrite chewable chocolate (pretty good) 500 mg

12 noon - bariatric advantage calcium citrite chewable chocolate 500 mg

6 pm - bariatric advantage multi chewable orange flavor
bariatric advantage calcium citrite chewable chocolate 500 mg

9 pm - sundown naturals perfect iron 50 mg with kirkland vitamin c 500 mg
twin labs b12 1,000 sublingual

Combining calcium and iron won't cause constipation.  If you take two of the Bariatric Fusion, you won't actually be able to absorb any of the iron in them because that much calcium will block the absorption of the iron.  So if you've been taking two of them at a time, you haven't really been getting any iron.

You also haven't been getting anywhere near enough calcium since four of them only has a total of 1200 mg calcium and some of it is calcium carbonate, which we can't absorb.

So anyway.  I don't think the vitamins are causing your constipation, but changing is a good idea so you will be able to get all the vitamins and minerals you need.

My schedule is about the same as the above poster.

Breakfast - multi, 500 mg calcium, D3, A, zinc

Lunch - 500 mg calcium citrate

Dinner - multi, 500 mg calcium citrate

Bedtime - iron, C

And B12 shots once a week.

Hmm makes sense then. The D3, A, and zinc i don't have. Do i need those too in combination of the Celebrate multivitamin?

I just take the D3, A and zinc because my labs showed I needed it.  Most people do need extra D3, but you would base that on your labs when you get them done next month.

The cause of the constipation may be lack of fiber.  Most of us don't get much fiber early out because we are so focused on protein and there's not enough room left for fiber in our little pouches.  Using MIralax daily will probably help, but you can also use a fiber supplement like Benefiber.

 I use a tasteless fiber powder in my protein shake in the morning and in  decaf coffee in the evening. It tends to keep things moving along. 

Hijacking and I'm sorry but I have a question. I will be taking opurity by unjury the have a bypass multi that is once a day. Plus calcium 2 chews at mid morning and 2 mid afternoon. The b12 at night. There is 50 mg of calcium and 30 mg iron in the multi. Will that be okay. Below is what their website says about the multi and iron.

Just trying to make sure I am good for the basics. Understanding I may need to take more depending on my individual labs. Thanks.
Iron

Iron deficiency anemia is the most common nutritional deficiency in the world.

Your entire body needs oxygen, and every cell depends on red blood cells to deliver that oxygen. To build red blood cells, iron is essential. Supplemental iron is needed to prevent anemia, a common side effect of weight loss surgery. Common symptoms of anemia are fatigue, and reduced capacity to exercise.
Getting enough iron is difficult because the body normally absorbs only 10% of iron from foods. Iron absorption is greatest in an acidic environment. Weight loss surgery reduces the size of the stomach and its ability to make enough acid for the best iron absorption. Plus, gastric bypass usually bypasses the duodenum and proximal jejunum, the most efficient absorption sites.

OPURITY uses a special iron, Ferronyl® Iron, which supports easier digestion, more complete absorption, and thus good iron levels in the blood. Each tablet has 30 grams, consistent with ASMBS recommendations.

A note about Iron in multivitamins, and calcium: Calcium blocks iron absorption depending on how much calcium is present. OPURITY? Bypass & Sleeve Optimized Multi uses only moderately low levels of calcium to minimize interference with iron absorption. We provide a separate chewable, Calcium Citrate Plus, which we recommend be taken at different times.

30 mg is NOT consistent with the ASMBS recommendations.  The ASMBS recommends 36 mg for men and women that have completed menopause and 54 to 63 mg for everyone else.  So I doubt 30 mg will be OK, but in the end you'll have to judge that by your labs.

The ASMBS also says we need 1500 to 2000 mg calcium citrate daily AND we can only absorb about 500 mg at a time, so we need to take three or four doses of about 500 mg each.  So you would need to add one or two more doses of the calcium chews.

Thanks
