Top 3 Best BCAA Tablets

These BCAA tablets by Oshun have everything that you would expect from most other BCAA tablet brands, however, there is the added bonus of vitamin B6. Vitamin B6 is needed by the body for amino acid metabolism in the muscles and helps the body to absorb BCAAs.
You get 120 tablets per bottle and 600mg of BCAA per tablet, which are pretty much the usual amounts expected when buying BCAA tablets.
These are a little more expensive than the next BCAA tablets in our best-of list, however, this is due to the added vitamin B6. If you don’t think that you will benefit from this due to already getting enough B6 in your diet, then I would go for our number two choice

How To Take BCAAs
BCAAs can be taken in three different ways; as a powder dissolved in a drink, as tablets, or as capsules. Due to the body absorbing powder the quickest, most people prefer to take BCAA powder. It also tastes great as well. In addition, it’s a lot easier to drink a shake than to swallow many capsules or tablets at a time.
When To Take BCAAs
As a rule of thumb, the best time to take BCAAs is pre-workout (30 mins before), or post-workout. Some people also prefer to take a dose during the day to delay muscle breakdown.
Across the board, most brands give pretty much the same information as to when to take BCAAs.
