Magnesium Bisglycinate Powder - 180gm - 40 Servings
Tax included. Free Shipping on Prepaid Orders
You’ve been taking magnesium for months. You still can’t sleep. The problem isn’t magnesium, it’s the form.
Most brands sell you magnesium supplement buffered with magnesium oxide or just simply magnesium oxide because it’s cheap to manufacture. Your body absorbs about 4% of it. The other 96% passes through your digestive system unused, which is also why oxide causes the laxative effect people blame on “magnesium.”
Bisglycinate is different. Each magnesium molecule is bonded to two glycine molecules so it travels through the intestinal wall intact via the dipeptide transport pathway. Absorption is significantly higher than oxide or citrate. More magnesium reaches your cells, which means you actually feel the difference.

Key Benefits
What iThrive Magnesium Bisglycinate supports:
-
Sleep quality — magnesium activates GABA receptors that help the nervous system wind down before sleep; glycine acts as an additional inhibitory neurotransmitter for calm
-
Muscle relaxation and recovery — required for both muscle contraction and the release that follows; may help reduce cramps and delayed soreness
-
Stress and anxiety — magnesium plays a key role in regulating the HPA axis (stress response); glycine supports a calming effect on the central nervous system
-
Migraine support — magnesium deficiency is consistently associated with migraine frequency; bisglycinate’s superior absorption makes it more effective for this target
-
Hormonal balance and PMS — magnesium may help reduce PMS symptoms including mood changes, cramps, and fluid retention
-
Bone health — works in concert with Vitamin D3 and Vitamin K2 for calcium absorption and bone mineral density
- Energy and metabolic function — participates in more than 300 enzymatic reactions including ATP production, DNA synthesis, and glucose metabolism
Pure formulation. Nothing unnecessary.
|
No magnesium stearate. No silicon dioxide. No artificial colours. No titanium dioxide. No talc. No preservatives. Most supplement manufacturers add these as flow agents or anti-caking agents to speed up production. We don’t. Every gram of this powder is magnesium bisglycinate - nothing filler, nothing synthetic. |
Practitioner’s Note
“I put this in every ALIVE client’s protocol and for good reason, across thousands of functional assessments, magnesium deficiency is the single most consistent finding we see, regardless of the presenting health concern. Standard magnesium supplements rarely move the needle because the form isn’t absorbed. Bisglycinate is the only form I’ve seen reliably restore magnesium levels and produce noticeable improvements in sleep, muscle tension, and mood within four to six weeks. If you’re sleeping badly, cramping, anxious, or constantly fatigued, this is almost always where we start.”

Magnesium Bisglycinate
Magnesium activates GABA receptors that calm the nervous system. Glycine, the amino acid it’s chelated with, acts as a separate inhibitory neurotransmitter, a natural dual-action sleep stack in a single ingredient.
Required for both muscle contraction and the relaxation that follows. May help reduce cramps, tightness, and delayed soreness after exercise without the laxative effect of cheaper magnesium forms.
Magnesium is a cofactor in over 300 biochemical processes — including ATP energy production, DNA repair, and glutathione synthesis. Most people running on empty are magnesium deficient and don’t know it.
Magnesium deficiency is consistently associated with migraine frequency, PMS symptoms, and stress response dysregulation. The bisglycinate form’s superior absorption means more magnesium actually reaches the cells where it’s needed.
Elemental Magnesium
Each magnesium ion is bound to two glycine molecules via the dipeptide transport pathway. This bond protects the mineral through digestion and allows it to be absorbed via the amino acid pathway, rather than competing with other minerals at the same intestinal transporter. The result is significantly higher intracellular magnesium delivery than oxide or citrate forms.
Single declared ingredient. No fillers, binders, or flow agents in the formulation.
Third-party lab tested for purity and potency. Full batch report available below.

Frequently Asked Questions
Magnesium
One declared ingredient: Elemental Magnesium (from Magnesium Bisglycinate powder) 440mg per serving (100% RDA). No fillers, no flow agents, no anti-caking agents, no artificial colours, no preservatives. Unflavoured powder. Third-party lab tested for purity and potency, full batch report downloadable on this page.
Magnesium oxide — the form used in most pharmacy supplements — has an absorption rate of around 3–4%. Bisglycinate absorbs significantly better because it’s chelated: bonded to glycine, an amino acid, which allows it to pass through the intestinal wall intact via the dipeptide transport pathway. Citrate is better than oxide but still relies on the same transporter as other minerals, creating competition. Bisglycinate bypasses this. More magnesium reaches your cells; less passes through unused.
No. The laxative effect associated with magnesium is specific to magnesium oxide or magnesium citrate — the form most brands use because it’s cheap. Bisglycinate is specifically chosen because it does not cause this. It’s gentle on the digestive system and suitable for daily use even at higher doses.
Mix 1 level scoop (4.4g) in 200ml water, stir well and then consume. We recommend taking it before bed since magnesium’s calming effect on the nervous system makes it particularly effective for sleep support at night. For muscle recovery, post-workout timing also works well. Can be taken with or without food. For first-time users, we recommend dividing the dosage into 2 x half scoops per day. One half scoop right after your breakfast and one half scoop 30-45 minutes before sleeping.
Yes. Magnesium bisglycinate pairs especially well with Vitamin D3+K2 (magnesium is required for Vitamin D activation) and with our Marine Omega-3 for a comprehensive sleep and recovery protocol. If you’re on the ALIVE program, your protocol will already include this, check with your practitioner for personalised dosing context.
Yes. Every batch is independently tested for purity and potency. The lab report for the current batch is available to download on this page — we publish it because we have nothing to hide and everything to prove.
Pharmacy brands (and most e-commerce brands at ₹200–400 price points) use magnesium oxide the cheapest form, with the lowest absorption and the strongest laxative effect. Some mid-tier brands use citrate, which is better but not optimal. Bisglycinate is the clinical-grade form used by functional medicine practitioners. It costs more to manufacture, which is why most brands don’t bother.
