Senior Health & Longevity Supplement Guide (65+)

Preventing nutritional deficiencies, muscle loss, and cognitive decline in older age.

Evidence Summary (TL;DR)

Seniors frequently face reduced absorption of Vitamin B12, higher bone resorption requiring Vitamin D3/K2 and calcium, and macular degeneration risks preventable with AREDS2 lutein/zeaxanthin.

500 - 800 mg elemental

Acid-independent absorption ideal for age-related hypochlorhydria

Timing: Bedtime or between meals

AREDS2 Free Lutein + Zeaxanthin
