Supplements that are ineffective
No matter how big and popular the advertisement of such products is and how tempting their names might be, most of them are not worth your money and will not enhance any part of your body or performance whatsoever.
Fat burners, for example, a name that really does sound appealing, only help burn your money, but not body fat.
Fat burners are also known as, BCAAs (Branched Chain Amino Acids”. The BCAAs are three of the nine essential amino acids. In a varied plant-based diet, you will get your BCAAs from your diet anyway. An addition of BCAAs is of no advantage whatsoever. For instance, a protein powder containing all essential amino acids or an EAA product may be the better choice with fewer costs.
Supplements for further hydration
The best hydrating drink out there is water. Depending on where you live water already contains electrolytes (K, Mg, Na, Ca). However, occasionally opting for drinks that contain higher levels of electrolytes is a good idea.
A drink fortified in minerals is mineral water with gas. Occasionally, drinking mineral water with lemon for instance, will be of benefit to you.
The most natural source of good quality and quantity of electrolytes is coconut water. Besides that, there are many sports drinks out there fortified with electrolytes. However, be aware when buying those since most contain unnecessary amounts of sugar.
