Our 2026 "Efficiency" Audits
The "Bioavailability" Stress Test
Not all pills are absorbed equally. We audit the Delivery Format (Tablets vs. Capsules vs. Liposomal Sprays). The Result: We have found that high-dose Vitamin C tablets often have an absorption rate of less than 20%, while Liposomal versions reach up to 80%. We rank brands on "Cost-per-Absorbed- Milligram."
The "FSA Safety" Audit (2026 Update)
The Food Standards Agency has issued new warnings regarding "Mega-Dosing." The Insight: We audit for Safe Upper Levels (SULs). Specifically, we flag any supplement exceeding 10mg of Vitamin B6 or 1,000mg of Vitamin C, which the FSA notes can cause reversible but uncomfortable nerve or digestive issues.
Personalized Subscriptions: The "Data" Test
We tested 10 "Quiz-based" vs. "Test-based" subscription services (e.g., Persona, VitaminLab, HUM). The Winner: Test-based services (using finger-prick blood kits) are the only ones we recommend for serious health goals. Quiz-based services are often just "marketing wrappers" for generic multis.
The "Usage" Cheat Sheet
3 Rules for Supplementing in 2026:
- The “K2” Requirement: If you are taking high-dose Vitamin D, you must ensure it is paired with Vitamin K2. Without K2, the calcium your body absorbs can settle in your arteries
rather than your bones. We audit for “D3+K2” synergy. - Verify the “Informed-Sport” Seal: Even if you are not an athlete, this seal is the gold standard for 2026. It guarantees that the product has been third-party tested for purity and does not
contain hidden contaminants. - The “Empty Stomach” Myth: Most fat-soluble vitamins (A, D, E, K) require dietary fat to be absorbed. Taking them with just water in the morning is a “Usage” fail. Always pair with a meal containing healthy fats.
Why Trust HowPeopleUse?
- We Use Independent Labs: We do not trust the label. We send samples to third-party labs to verify that the mg on the bottle matches the mg in the pill.
- No Affiliate “Ghost” Writing: We only link to products that pass our safety and purity thresholds, regardless of the commission rate.
- Regulation Watch: We track FSA and MHRA alerts daily to ensure no “blacklisted” or “counterfeit” products appear in our guides.
