TL;DR: Older adults often have lower vitamin C status, and supplementation 400 mg–2 g/day can modestly improve endothelial function, lower blood pressure slightly, and is linked in cohort studies to reduced risks of CHD, stroke, and heart failure. Benefits mainly appear when baseline vitamin C is low. Food-first intake is preferred; supplements are safe up to 2,000 mg/day. Linus Pauling , awarded the 1954 Nobel Prize in Chemistry for his groundbreaking work on the nature of the chemical bond, later became one of the most vocal champions of high‑dose vitamin C. In the early 1990s, he argued that daily intakes ranging from 3 to 18 grams, combined with lysine and proline, could help strengthen blood vessel walls and reduce the binding of lipoprotein(a) — a nutrient‑based strategy he framed as an inexpensive tool for cardiovascular support. Pauling’s broader message centered on maintaining healthy vasculature , from endothelial function to collagen integrity , and he often pointed to dose...

Bioactive or highly bioavailable supplement forms are those the body absorbs and utilizes more efficiently, often delivering better results at lower doses and with fewer gastrointestinal side effects. These formulations typically rely on chelation —binding a mineral to an organic molecule such as an amino acid or acid—rather than inexpensive inorganic salts like oxides, sulfates, or carbonates. Chelation helps protect the nutrient in the gut, reduces interference from inhibitors such as phytates, and improves uptake. Quick Tips Look for labels indicating chelated minerals such as “bisglycinate,” “picolinate,” or “glycinate.” The elemental amount—the actual mineral content—matters more than the total compound weight; chelated forms may list fewer milligrams but deliver more usable mineral. Pair fat‑soluble nutrients with food, and separate high‑dose minerals like zinc and magnesium to reduce competition. Consider testing levels such as serum zinc, RBC magnesium, or 25‑OH vitamin D be...
