💡 Did You Know? Interesting Facts About Supplements
🤔 Does Creatine Cause Baldness?
No! This is a myth originating from a single 2009 study. Later studies found no link between creatine and hair loss.
💊 Can You Overdose on Vitamins?
Yes! Fat-soluble vitamins (A, D, E, K) accumulate in the body and can be toxic. Water-soluble ones (C, B group) are excreted in urine.
🥛 When Is the Best Time to Drink Protein?
"Anabolic window" after training lasts up to 2 hours (not 30 min as previously thought). The most important thing is total daily protein intake.
⚡ BCAA or EAA?
EAA are more effective because they contain all 9 essential amino acids. BCAA contain only 3. If you choose one — take EAA.
☀️ Why Is Vitamin D Needed in Lithuania?
In Lithuania, solar UVB radiation is sufficient for vitamin D production in the skin only from May to September. For the rest of the year, supplements are necessary!
🦴 Does Collagen Really Work?
There is evidence that collagen peptides may improve skin elasticity and reduce joint pain, but the effect is not as pronounced as that of other supplements.
