Is Dihydroquercetin The Same As Quercetin?
1. Stability Normal Quercetin powder is "fragile." Light and heat erode it. DHQ is more durable and stays stable in the bottle longer, so you get the potency you paid for when you take it.
2. Antioxidant Power Both reduce oxidative stress, but DHQ has greater "muscle." It neutralizes free radicals better, hence higher-end longevity supplements use it.
3. Absorption Puzzle Now things get intriguing. Quercetin is notoriously difficult to absorb (it must be taken with lipids). DHQ is more water-soluble than previously thought, despite prior studies suggesting reduced uptake. It is usually easier for your body to process and use than regular powder.
4. Body Response Different "workload" distribution. Standard Quercetin has numerous routes and is significantly impacted by gut microbes. DHQ, however, is liver-dominated. It's examined for liver protection because it's metabolized neatly there.
5. Security and Feel Both have excellent safety histories. Some consider DHQ the "gentler" alternative. It's low-toxic and doesn't induce system strain like high-dose Quercetin.
