Have you tried natural supplements to boost your energy and immunity yet?

Natural supplements like vitamin D (2,000 IU), vitamin C (1,000 mg), zinc (15-30 mg), elderberry, and B-complex show evidence for boosting energy (via ATP/mitochondria) and immunity (enhanced NK cells, reduced infection duration). Daily use is safe for most if dosed properly, but test deficiencies first—excess risks GI upset or interference.[ods.od.nih]
