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
- Evening (45 min before bed): Magnesium Bisglycinate Powder

Powder doesn't have any side effects bit still haven't been able to see any calming effects
I have been using this supplement for a while and am very happy with the decision. I highly recommend it to anyone facing Gut issues. It helped me to improve my digestion and tackle my gut issues.
Several issues that aren’t customer friendly in my opinion. 1. The container is only half full when opened. Assuming it is sold by weight, having a large container is unnecessary and also points to false marketing.
2. The directions for use is 1/2 scoop. If so, why not make the scoop the correct dosage size and if anyone needs more they can easily take two scoops. As it is it’s not easy to get exactly half in the scoop.
3. The powder does not dissolve in the water. Even after stirring several times. It’s more like a suspension in the water and some of it gets left behind in the glass.
4. I have only recently started taking this supplement so cannot speak to the efficacy of the product. Will update after my next blood test.
Thanks for your review.
Yes the magnesium bisglycinate powder does not completely dissolve in water as it is a mineral and I would recommend you that you drink the powder immediately after stirring it in the water.
1) Yes the container is filled just more than half but I can assure you that the jar contains 200 grams of magnesium powder accurately. And yes, the jar size is a little bigger but that makes the label bigger too and more readable .Although we might change the jar in the future batches, thanks for the feedback.
2) Yes it can be a little difficult to measure half scoop but it can still be done. We recommend gradually increasing each individual's magnesium dosage and we recommend starting with half scoop at a time and total 1 scoop per day.
3) Yes the powder will not dissolve completely in water.
4) Sure, do let us know your results if you're open to sharing them. According to our research, the serum magnesium marker in India for magnesium levels doesn't give a proper picture of the magnesium levels in our body.If you have the access to RBC magnesium, it is a more accurate marker for checking checking magnesium levels in the body.
I liked the quality and it has got immense positive effect on my health, it has been a week feels good, hoping to be the same in future, so far nothing negative effects.
B Complex is a must for Vegetarians and vegans. I am person who is not able to consume non-veg foods on a daily basis and need all the B vitamins. I can see that I am better able to manage stress and maintain my energy levels throughout the day. I would recommend this supplement to everyone whether you are eating non-veg or not.
I take this Magnesium powder twice in a day, and I can really feel the energy difference in my body. Also I feel more relaxed and having good sleep after taking this supplement. I would suggest everyone to have this product in your day to day life to stay healthy and stronger. Thanks for getting this product into the market and keep up the good work iThrive.
Excellent Product
It's helped me in developing immunity
If you make it in the form of capsule, it will be super easy to consume
A quality product without any preservatives or unnecessary things, that should not be there in a supplement.
Been a few weeks using the product. The most visible effect is that my sleep cycle is now very intense. I don't wake up tired anymore. Post-gym muscle recovery has also improved; compound lifts do not feel as taxing on the muscles as they did before.
Thoughtfully combined! Good results!
Good combination
I see a difference in sleep. But not felt no difference in recovery. Hoping to see more effectiveness in coming days.
