1. How do antioxidants support the immune system?
Antioxidants help neutralize free radicals, the unstable molecules that build up from stress, pollution, and normal metabolism. Keeping them in balance helps your immune system do its job.

2. Which Omnitrition products are in this collection?
Three: Shield Antioxidant, PhytoNutrients, and Omni 4 Liquid Concentrate with Glucosamine. Each one works on its own or as part of a daily routine.

3. Can I take Shield, PhytoNutrients, and Omni 4 together?
Many customers pair them since each covers a different base. Read the labels and check with your doctor if you take medication or manage a health condition.

4. Are these supplements plant-based?
Yes. Omnitrition builds its formulas around plant-based ingredients and produces them in a cGMP-certified facility with rigorous quality testing.

5. When should I take antioxidant supplements?
Most people take them with a meal, often breakfast, since food helps with absorption and makes the habit stick. Follow the directions on each label.

6. Does this collection qualify for free shipping?
