Hi, i wanted to know if i can use both bio zinc and bio magnesium together daily. And right now i just started my weight training, can i use creatine also? is there any potential side effect when using these three products together?
I know that your site says that the bio magnesium is the same product with just a different look, but the actual tablets feel different. Can you explain why ?
What are side effects of both BioMagnesium and Mag Min Thanks
Hi, when it says ''Manganese amino acid chelate (manganese 4 mg) 40 mg'' How come the ingredients are listed like this, why does it show a different amount in brackets? If it's 40mg that seems like an awful lot if the upper daily limit is set at 11mg. I took a pill of Bio Magnesium and a Blackmores Bio Zinc together because I only noticed the amount listed in the brackets, and now I'm worried it overdosed me. The way the magnesium is listed also confuses me.
I have allergies to ALL nuts, coconut and ALL seeds or anything that has a seed - like watermelon, strawberry, tomato, banana, etc etc. - Is the Bio Magnesium ok for me to have? Anyone else have these? Thanks
My son is five years old. Can he take this? Take 1 tablet a day ?
Please can you tell me if bio magnesium muscular support suitable for vegetarians?
Why do a lot of your products contain high amounts of vitamin B6 ( Pyridoxine hydrochloride) ? , Much higher than the recommended daily intake and at levels that if used over a long period of time could possible cause nerve damage
