I want to discuss something that I know many of you have either used or heard about in the supplement industry.
—–> BCAA Supplements.
▶︎ Do you supplement with BCAA’s?
Although they show minor benefit in reducing muscle wastage (Catabolism), the negative effects may not be worth it.
Here’s what BCAA’s can do to your brain:
🚫 DEPLETES SEROTONIN AND DOPAMINE:
Experiments have shown that BCAA ingestion displaces aromatic amino acids at a transporter located at the blood-brain-barrier (Smith et al., 1987); further, BCAAs are thought to induce protein synthesis and plasma tryptophan is incorporated into these newly synthesized proteins (Moja et al., 1991).
Consequently, brain levels of aromatic amino acids decrease, which induces acute depletion of cerebral neurotransmitters including Dopamine and Serotonin (Fernstrom, 2005).
⭐️Various scientists invoke that increased BCAA levels in obese individuals and the subsequent blockade of serotonin (and dopamine) production in the brain to the constant insatiable cravings, anxiety and depression in these individuals (Breum. 2003; She. 2007; Coppola. 2013). Now, it is also true that BCAA’s blunt an increase in 5-HTP synthesis in the brain (-48%;) with the concomitant -25% decline in hypothalamic Dopamine (the “get going neurotransmitter”) after ~30mins. This sheds light on the anti-fatigue mechanism of BCAA supplementation…via a reduction in serotonin synthesis.
✅EAT REAL FOOD INSTEAD:
High protein foods generally speaking are better for the body to absorb and utilise.
If this is difficult to achieve, then supplementing with EAA’s may be necessary.
🌀ERGOGENIC FACT OF THE WEEK:
—–> Serotonin Weakens Smell Perception
Odor-evoked synaptic input to glomeruli was attenuated by increased serotonin signalling through serotonin 2C (5-HT2C) receptors and amplified by decreased serotonergic activity.
—–> So any drug/supplement or herb that blocks 5-HT2C receptors may actually enhance sense of smell. More on this soon.
