Jarrow B severe side effects

21 Replies

Hi I've started a new post and added to my previous one ...i am continuing to try and get diagnosed with secondary hypothyroidism and my recent blood test showed low folate and ferritin and although I've been taking a vit b complex I was advised to change to a better one jarrow b which I did. I took my first tablet today with breakfast and about 2 hours later I started itching all over. 6 hours later I was bleeding with all the scratching so I took an antihistamine. it's shocked me it could cause such a bad reaction and although I was told about a niacin rush I didn't know about this extreme itching. obviously I can't take this any more which is a shame because I.know it's s good one and expensive too. does anyone know why this happened and what caused it? plus any alternative thank you

You're not the first member who hasn't got on with Jarrow B Right. It's not one I suggest, I don't like the balance of the vitamins in it, I much prefer Thorne Basic B and did very well on that. I've now changed to a wholefood one with minimal B12 as my Active B12 is very good.

it was the other administrator who recommended it trust me to pick that of the 2 suggested. what causes the sudden itching which b vit do you know? I don't want to spend more money on another one if I'm the same as they're not cheap

A very quick Google shows that B12 can cause itching, as can B6, also B3 (niacin). Also it could be due to the excipients.

I wonder if you'd be better looking at the wholefood B Complex instead of synthetic vitamins.

I've been fine on the complex from my health shop its raised my b12 but not my folate..i have folic acid tablets by Solgar I think I'll add as well. I'm too scared to try another one now

Hi Banjogirl

This is the one I'm using, good amount of folate and very small amount of B12 which is what suits me:

There is another one which has more B12 but the serving size is 2 capsules and it's a fair bit more expensive:

The jarrow formula Vit B right is not synthetic,I take them for over 5 yrs and never had no any skin problems, no any side effects. This Vit B complex has very good -right balance between each other.

Can you clarify what you mean by "not synthetic"?

Also, odd that it contains two forms of vitamin B6.

Esya47

The jarrow formula Vit B right is not synthetic

But they're not wholefood based because it would say if they were so they come under the heading of synthetic

From enzymedica.com/blogs/natura...

Whole food supplements will either list their food sources or say somewhere that they are 100% plant or animal based.

By comparison, synthetic supplements will either list the nutrients individually, like Vitamin B12, for example, or use the names of chemicals.

Some people have had side effects from them, others haven't, it's the same with any supplement or medication. I haven't said they're not good, read my reply to SilverAvocado further down.

SeasideSusieRemembering in reply tosilvisilvi

Which one in particular, it looks like they do several versions.

silvisilvi profile image
silvisilvi in reply toSeasideSusie

I have not seen other versions,these are Veg-tablets,it says B-50 Complex,white-blue bottle.Has 200 RDA of B-12 but I have to have bood test to be sure.

SeasideSusieRemembering in reply tosilvisilvi

OK, found it now.

Not a good idea for these reasons:

1) It contains folic acid and the methylfolate form is recommended.

2) It contains cyanocobalamin and the methylcobalamin form is recommended.

3) Any of these B-50, B-100 types aren't particularly well balanced. The same amount of everything isn't a good idea.

4) It contains 50mg B6. Long term high dose of B6 can cause nerve damage, amongst other health problems.

The average daily recommended amount of B6 for an adult is about 1.9mg which should be available from food. The amount in a supplement taken regularly is recommended to be 10mg.

SeasideSusie, could you please explain a bit about what these whole food tablets are and why you've chosen them over synthetics?

I had a look at the two products you linked below and I've never seen anything like it. They look very interesting.

SA - As you've probably noticed from the labels they're food based - dehydrated/concentrated whole foods - so the vitamins come from the foods listed on the label (which should say "plant based" and list the plants used). Concentrated forms of what we would eat in our diet to give us the vits and mins we need. As they are food then they will be bioavailable.

Synthetics are artificially made from chemicals - not always bioavailable (look for that word on the label, eg it's on Thorne Basic B and Igennus Super B but not on Boots and Natures Best to name just two) so may not be recognised by the body and may not be as absorbable or usable.

I am using Naturelo B complex at the moment, it seems to be maintaining my folate level and I chose that one due to it's small amount of B12 as my Serum B12 with the GP is way over range and they don't like that, and my Active B12 (self tested) was 162 (37.5-188) in January. I'm due to retest vits at the end of the year so will see how things are then.

Also, take Vit C for example. Most Vit C is ascorbic acid but you can get Vit C from fruits and an Acerola Cherry supplement will be better than ascorbic acid. Eating liver can generally raise ferritin levels more quickly than iron tablets (I'm trialling desiccated liver capsules at the moment).

These are just comments from a layman, I've not researched or looked at any scientific papers so I'm not saying one is better than another. Personally I like as natural as possible if I can get it, and as few excipients as possible.

That does sound very interesting! Thanks for the information.

silvisilvi in reply toSeasideSusie

Correct,because ascorbic acid is just one conponent of the real V-C,and is usually made of GMO corn, natural vitamin C has many other substances besides ascorbic acid which is pratically useless,correct me if I am wrong,so acerola,pomegranate,kiwi,peper,etc.

I recommend Igennus Super B complex in preference to Jarrow. Igennus is small tablet. Full dose is two per day, but always start on one, or even half a tablet

Igennus has folate in, not folic acid.
