Is Magnesium 400 Keto?
Yes, Magnesium 400 is keto-friendly. This supplement contains zero carbohydrates and no sugars, making it a safe addition to a ketogenic diet. Our analysis confirms that all ingredients, including the capsule shell, are free from hidden carbs that could disrupt ketosis.
The Ingredient Breakdown
When evaluating a supplement for the ketogenic diet, we look beyond the headline ingredient and scrutinize the fillers, binders, and capsule materials. Magnesium 400 presents a surprisingly clean profile for a general-purpose supplement.
The primary active ingredients are Magnesium oxide and Magnesium bisglycinate. These are simply mineral forms of magnesium and contain no carbohydrates. They are used to boost your magnesium levels, which is crucial on keto to prevent the 'keto flu' and muscle cramps.
Next, we have the capsule itself. The ingredient Gelatin is listed, which is derived from animal collagen. Gelatin is 100% protein and fat, containing virtually zero carbohydrates, making it the ideal choice for keto dieters compared to plant-based capsules like hypromellose (which can sometimes be processed with starches).
Looking at the inactive ingredients, Microcrystalline Cellulose is a common bulking agent. It is a refined wood pulp and is considered a fiber, meaning it has a negligible net carb impact. Similarly, Magnesium salts of fatty acids and Silicon dioxide are anti-caking agents used in microscopic amounts; they do not contribute to your daily carb count.
Finally, we have Pyridoxine HCl (Vitamin B6) and L-Tryptophan. These are amino acids and vitamins with no carb load. The only potential red flag in any supplement is Titanium dioxide, used here for color. While it is technically carb-free, some health-conscious consumers prefer to avoid it due to concerns about bioavailability and gut health, though it is not a 'keto' disqualifier.
Nutritional Value
From a macronutrient perspective, Magnesium 400 is virtually a 'free' item on the keto diet. The serving size is typically one capsule, and the nutritional label will show 0g of carbohydrates, 0g of sugar, and 0g of fat. This means it fits strictly within the ketogenic macros, which usually limit carbs to under 20-50g per day.
Because it contains no sugar or starches, it will not spike your insulin levels or kick you out of ketosis. The calorie count is also negligible (likely less than 5 calories per capsule), so it won't impact your daily energy balance or weight loss goals.
However, it is important to note that while the supplement is keto-compliant, the Magnesium oxide used here is not the most bioavailable form. It is often used because it is cost-effective and allows for a high dosage of elemental magnesium, but it is not absorbed as efficiently as chelated forms like magnesium citrate or glycinate. While it fits your diet, it may not be the most effective option for correcting a severe deficiency.
