Frequently Asked Questions
Which vitamins most directly support immunity?
Vitamin D3, vitamin C, zinc and B vitamins (notably B12) are the most commonly recommended for immune support. Many quality multivitamins combine these with antioxidants like vitamin E or selenium to bolster immune defenses.
Are liquid or gummy multivitamins better absorbed than pills?
Absorption depends on formulation and individual digestion. Liquids can be absorbed faster for some people, and methylated nutrient forms improve bioavailability; gummies are convenient but may provide lower doses per piece. Choose the format you will take consistently and consult your provider if you have absorption concerns.
Can multivitamins upset my stomach?
Yes — iron, high doses of certain minerals, or concentrated formulas can cause nausea or stomach discomfort in some people. Taking the vitamin with food, switching format (gummy, liquid), or choosing formulas labeled gentle can reduce stomach issues. If problems persist, stop use and consult your healthcare provider.
