People use the term “multivitamins” to refer to all manner of mineral supplements, and not specifically vitamins only. Some people have been sceptical about the effectiveness of mineral supplements, for mainly the following reasons:
*most people take them to prevent illnesses and not to cure sicknesses. So their effect is not easily noticeable because they dont fix a problem
* the multivitamin industry is not rigorously regulated like the medical drug industry, so some rogue players have been known to just sell chalk dust and gotten away with it.
I will give you my personal experience with mineral supplements. I embarked on a training program 6 years ago as i was fed up of weighing 120 pounds at 5’7. My goal was to build a better physique drug free (without steroids). As part of that quest, I researched heavily on supplements and have tried a range of them over the years. Now im sitting at 221 pounds solid, drug free. Here is my experience with some mineral supplements:
Vitamin D3
I took this vitamin to build strong bones and yes it worked. How do I know? Within days of taking it, my nails started to grow stronger and faster.
Vitamin K2
This one boosts the body’s ability to produce more testosterone. I knew it was working because it also caused my nails to grow faster and my hair also.
Fenugreek
I was taking this supplement to boost my natural testosterone production. I had to stop taking it because it was giving me gyno (puffy tender nipples). So it was working, but the gyno was a side effect I wasnt happy with.
Calcium D Glucarate
This ordinarily helps your bones to absorb calcium better and to lower oestrogen levels from the male body. I took this one to fix the gyno problem mentioned above. Within 2 weeks of taking it, my puffy tits had vanished. So it works.
Boron
This mineral is known to help boost natural testosterone in the body. When i started taking it i noticed that my nails and hair also grew stronger and faster. So it works.
D-Mannose
I used to suffer from urinary tract infections on a regular basis. That stopped when I started to take this mineral. No more UTIs. So it works.
All the above supplements are available from any good health store or from Amazon. If i cant buy something from a health store or from Amazon, then i dont want it in my body, its that simple.
As I pointed out earlier, some players in the multivitamin industry are rogue and will sell shoddy or even fake stuff to make a buck. So i do my research and make sure that the manufacturer has a good reputation, a solid track record in the game and many good customer product reviews. I mainly buy my supplements from 2 key manufacturers that I trust fully - Solgar and Nu U Nutrition.
I hope my response is helpful.
