HYZEN is a clean-label hydration mix designed to support daily hydration routines with a clinically inspired electrolyte profile and a premium taste. It is built with the POTS community in mind and for anyone who needs reliable hydration support.

HYZEN was created with the POTS community in mind and is designed to support hydration as part of an everyday routine. Everyone's needs are different, so if you have POTS (or any medical condition), we recommend discussing electrolytes and sodium intake with your clinician.

HYZEN is a dietary supplement intended to support hydration and electrolyte intake. It is not a medication and is not intended to diagnose, treat, cure, or prevent any disease.

HYZEN is sweetened with a balanced system of allulose, erythritol, and monk fruit extract to deliver a clean taste without added sugar. This approach supports daily routine use and helps avoid the overly sweet or heavy taste common in many hydration products.

HYZEN is formulated to be sugar-free with 0g added sugar (final sugar values will be shown on the Supplement Facts panel). We avoid traditional sugars and use non-sugar sweeteners for taste and daily adherence.

HYZEN contains erythritol, a sugar alcohol used to support sweetness without added sugar. Some people prefer to introduce sugar alcohols gradually to assess personal tolerance.

Mix 1 stick into 16 oz of water. Shake or stir well. For best taste, use cold water.

Yes. If you prefer a stronger flavor, use 12-14 oz. If you prefer lighter, use 18-20 oz.

Most people use HYZEN in the morning, mid-day, or whenever they want hydration support. If you are following a clinician's guidance for sodium/electrolytes, use HYZEN within that plan.

This depends on your personal needs, diet, and clinician guidance - especially for anyone monitoring sodium intake. Start with one stick per day and adjust as needed.

HYZEN is built around three standards: (1) supportive daily hydration design, (2) clean label commitment, and (3) consistency and quality you can trust. We obsess over both the formula and the taste so it is something you can actually use consistently.

HYZEN is formulated to taste premium without unnecessary additives. Refer to the product label for the exact sweetener system and amounts.

Check the Supplement Facts and ingredients panel for the exact details for your version. Our goal is a clean, modern profile that fits everyday use.

HYZEN is designed as a hydration formula. If any product variation includes stimulants, it will be clearly labeled. Always refer to the label for the specific SKU.

We aim for broad compatibility, but always refer to the label and allergen statement for the most accurate information. If you have severe allergies, contact us before use.

Total sodium per serving is listed on the Supplement Facts panel. If you are monitoring sodium for any reason, use the label values as your source of truth.

If you have a medical condition, are pregnant/nursing, take prescription medications, or have been advised to limit sodium/electrolytes, consult your healthcare provider before use.

HYZEN is formulated for adults. For children, consult a pediatrician before use.

You can, but be mindful of total daily sodium and electrolyte intake. If you stack products, use the labels to track totals and follow clinician guidance if applicable.

We take quality seriously and prioritize documentation and consistency. We maintain supplier documentation and product records to support a high standard of manufacturing discipline.

We can provide ingredient or lot documentation when appropriate. If you need documentation for a specific batch, contact our support team and we will guide you.

HYZEN® V4 HERO includes 500 mcg of Vitamin B12 to support neurological function, energy metabolism, and autonomic health. This level is commonly used in clinical nutrition and is especially relevant for individuals with POTS, dysautonomia, or fatigue-related conditions, where B12 needs can be higher than average.

The Daily Value (DV) for Vitamin B12 is very small (2.4 mcg). Because HYZEN provides B12 in micrograms and uses an active form, the percentage appears high. This does not mean the amount is unsafe.

Yes. Vitamin B12 is:
• Water-soluble
• Non-toxic
• Has no established upper limit
Any excess B12 your body does not need is naturally excreted.

HYZEN uses methylcobalamin, the bioactive form of Vitamin B12. This form:
• Is ready for the body to use
• Does not require conversion in the liver
• Is often preferred in clinical and neurological settings

Higher-dose B12 is commonly used by:
• Individuals with POTS or dysautonomia
• Those with low or borderline B12 levels
• People with digestive or absorption challenges
• Individuals experiencing fatigue or neurological stress

Vitamin B12 is not a stimulant. It does not act like caffeine. Most people tolerate it very well, even at higher doses. If you are sensitive or under medical care, consult your healthcare professional.

HYZEN is designed for daily hydration support. If you are already supplementing with high-dose B12 elsewhere, you may wish to factor that into your routine.
