Foundational Stack
Tax included. Free Shipping on Prepaid Orders
The four supplements your body needs every day - together for the first time.
The Foundational Stack brings together iThrive's four most clinically essential supplements into one daily protocol. Not a promotional bundle. A deliberate stack — built around the nutrients most commonly deficient in Indian adults, in the forms that actually absorb.
What's Inside
Magnesium Bisglycinate Powder
Chelated magnesium in the bisglycinate form is the most bioavailable oral form available. 440mg per serving. Supports deep sleep, muscle recovery, and nervous system regulation. Gentle on the stomach. No laxative effect.
Active B-Complex
Methylated B vitamins in their active forms, including Methylcobalamin (B12) and Pyridoxal-5-Phosphate (B6). No conversion step required by the body. Supports cellular energy, mood regulation, and cognitive clarity throughout the day.
Zinc Defense with Copper and L-Carnosine
Zinc glycinate is one of the highest bioavailable form of zinc. Paired with copper to maintain the zinc-copper ratio, and L-carnosine for gut lining support. Supports immune function, hormonal balance, and skin integrity.
Probiotics with Prebiotics
A synbiotic formula featuring named, clinically studied strains: LactoSpore®, DE111®, and Livaux®. Not generic CFU counts but specific strains with published clinical data. Seeds and feeds the gut microbiome to support digestion, immunity, and nutrient absorption.
Why These Four
These are not four random bestsellers. They are four nutrients that work in sequence:
- A healthy gut (Probiotics) improves absorption of everything else.
- Magnesium is required for over 300 enzymatic reactions, including B-vitamin metabolism.
- B-Complex fuels the cellular energy pathways that Magnesium activates.
- Zinc supports the immune and hormonal systems that the entire stack depends on.
Taken together, they address the four most common nutritional gaps in modern Indian lifestyles: poor sleep, low energy, digestive dysfunction, and immune vulnerability.
How to Take It
- Morning (with breakfast): Active B-Complex · Zinc Defense · Probiotics with Prebiotics
