"Methylfolate is more bioavailable than folic acid"
True. The active 5-MTHF form skips a conversion step that people with MTHFR variants struggle with, avoiding unmetabolized folic acid.

"Boosts energy and brain function"
B vitamins only relieve fatigue or fog caused by an actual deficiency. In well-fed adults they add nothing.
PubMed: Kennedy, B Vitamins and the Brain, 2016 -
"Probiotics and enzymes promote digestion"
A once-daily caplet holds too little probiotic and enzyme to matter, and both categories lack strong evidence in healthy adults.

"$38 for a 30-day multivitamin"
Comparable methylated multivitamins (Thorne, Garden of Life) run $20-30 for a month. You're paying a premium for branding.
Consumer advice
If you have an MTHFR variant or just prefer methylfolate and methyl-B12 over synthetic folic acid, this is a reasonable pick. Skip the 'brain-boosting' and 'energy' hype — a multivitamin only moves those needles if you're deficient. Compare against Thorne or Garden of Life methylated multis before paying $38. The probiotics and enzymes here are almost certainly at token doses, so don't buy it for gut benefits. Note the odd '$38.00 / $38.02' pricing and 'sells out fast / Stocks Available: 3' scarcity cues — mild pressure tactics, not deal-breakers.
Claims vs Evidence
MODERATE1 of 5 claims supported by evidence. These grades score the marketing, not the product — a claim only counts as supported when the label discloses a dose that matches the studies behind it, so blends that hide doses cap at “partial” no matter how good the formula is.
