In general, which type of vitamins are more likely to accumulate to toxic levels if take in excess (ex supplements)? WSV or FSV?

When considering vitamin toxicity risk from supplements, different vitamins behave differently in the body. 
Option 1: Water soluble vitamins (WSV) — These are generally not stored in large amounts. They tend to be excreted in urine when consumed in excess, so the risk of accumulation and toxicity is relatively low compared to fat-soluble vitamins. This makes this option less likely to be the correct choice for toxicity due to excess dosing. 
Option 2: Fat soluble vitamins (FSV) — Fat-soluble vitamins are stored in body tissues, particularly liver and fat, and are eliminated more slowly. Because they can accumulate with repeated high intake, excess supplementation increases the chance of reaching toxic levels. This aligns with established understanding of vitamin fat-soluble storage and toxicity risk. 
Option 3: It depends on the individual — While individual factors (like absorption, metabolism, or existing liver or kidney conditions) can modulate risk, the general pharmacokinetic distinction remains that FSV carry a higher baseline risk of accumulation and toxicity with excess intake. 
Option 4: Neither. Excess will be excreted in the urine by the kidneys — This is true for many water-soluble vitamins, but not for fat-soluble ones, which can persist and accumulate. Relying on kidney excretion alone overlooks the storage and slower clearance characteristics of FSV. 
Thus, weighing the general pharmacokinetic profiles, the scenario described points to fat-soluble vitamins as the ones more prone to toxic buildup with excess supplement use.
