This has been a great product for me for many years. I also appreciate a company that takes their product seriously and cares about the product they are putting out to people i.e. safety and performance.
I switched to this brand and also started taking 2 in the morning and 2 at lunch. Never in the evening! Seems to make all the difference. I can sleep normally finally! Good stuff!
I really appreciate the mag supplement. That combined with the electrolyte supplement have made a big difference creating more quality sleep and eliminating leg and other muscle cramping. Best regards, Laurie
This is truly the best magnesium I've ever tried. Some of the benefits are better sleep calm demeanor and less anxiety. It truly feels like it's regulating my system. Thank you for this magnificent product!!!
Helps with relaxation and sleep
I notice that I sleep better since I found out that it's best to take magnesium in the AM rather than just before bed. I'm also calmer. My only negative is that I run out before the automated shipment shows up...but just by a few days. No big deal I guess. Good product.
I love this Health by Principal magnesium. I take 300mgs a day and it does not bother my stomach or make me feel drowsy at all.
I have used many magnesium supplements over the years and this is by far the best complex mag I've ever used! I also use HBP's electrolyte support, B1 monthly. I can't live without them!
Good mix of magnesium with clean ingredients. Would recommend!
Different forms of magnesium are absorbed and utilized by different tissues. A single form, may support the nervous system without fully addressing cellular energy or cardiovascular pathways. The four-form blend ensures broader coverage across the body's needs.
Magnesium replenishment is not immediate. Most people who follow consistent protocol-aligned habits, correct timing, food pairings, adequate salt and hydration, report noticeable differences within 2–6 weeks of consistent use.
Iron competes with magnesium for receptors, so avoid taking them together. Calcium supplementation (pills) should also be separated from magnesium. Taking magnesium with food that naturally contains calcium is the correct approach, this supports absorption rather than competition.
Whether you're looking for calmer evenings, deeper sleep, muscle recovery, or mineral support. Complete Magnesium is a simple daily step toward feeling more balanced.
