The B-50 product is junk. It is all so called synthetic vitamins that are nothing more than "chemical activators," not vitamins that nourish the body.
It says the complex provides 50 mg. of 10 important vitamin B supplements. Most doses meet the USRDA. B Vitamins are precursors of coenzymes involved in the conversion of cellular energy, manufacture of hormones and proteins, and repair and maintenance of nerve structures. They also function as lipotropics which converts fats to other useful products.
What they are saying is that vitamins that are found in food that contain cofactors and natural nutrients do those things. Their vitamin product wasn't the ones used to come to that conclusion, right? Right.
It is a very well known fact now that chemical activators like in that product only help you at first for a short while and then damage your DNA. This actually shortens your life expectancy.
When you take this garbage, you probably will notice right away that your pee turns yellow. Ever wonder why? Your body is trying to tell you something. It would be better for your body to put the bottle of "B" chemical activators into a strong plastic bag and take it to the hazardous waste dump and deposit it there. If you flush them, you may be risking fish getting it or worse, going into your reclaimed water supply.
A good example of why this happens is look at the Thiamine, for example, vitamin B-1 in the bottle. It is made from "Coal Tar." A non living, chemical.
The vitamin b-12 is most likely cyanocobalamine from a vegetable source. Your liver, if the pill dissolves in time, has to convert this into methylcobalamine before the body can use it. Normally, B-12 comes from an animal source and is broken down by protein digestive enzymes in the stomach to convert the larger molecules into smaller molecules.
Your intestinal flora, that is about 3/4 of your immune system, is responsible for making most of your "B" vitamins, but if you've taken just 1 antibiotic, your intestinal flora has been destroyed and you are not getting good "B" vitamins into your body. You need to get a good quality probiotic with the right balance and type of bacteria to replenish this. You can also get "B" vitamins in your food, but not enough to fix the problem from taking antibiotics.
The best source of "B" vitamins I've ever found in 40 years of researching this is at: www.healthline.cc (not .com). This product contains "B" vitamins that are from living sources of friendly bacteria production and therefore you are getting them in their "end chain" form. This is highly biologically active and very potent. You will notice after taking this, you will not see "yellow pee." It is being digested quickly into your body. It is in liquid form and is alive when you get it.
The probiotic these people sell is excellent. There are 12 different cultures in this and the potency is wonderful.
I suggest you get both those items and for the first couple days, only take 1/2 tsp. in water or juice. Increase it to 1 - 2 tsp. per day for about a month.
Take the probiotic, 1 in the a.m. and then 1 in the p.m. After doing this for 30 days, you can stop taking the "B" vitamins or as I do, take 1 tsp. per day. Keep taking the probiotics and then eat lots of fermented vegetables and fermented RAW dairy products. This is what the cultures in the world do that have NO cavities, NO heart disease, NO cancer, and NO diabetes.
