ProLon, sold under the vendor name Prolon Life, builds its products around the fasting mimicking diet developed by Dr. Valter Longo and researchers at the University of Southern California. The idea is to supply food that keeps the body in a fasting-like state while still providing calories, so a person can complete a fast without going without food entirely.
MediDepot carries the ProLon range as a nutrition and wellness line rather than a clinical one. The products are food and supplements, not medical devices, and they are chosen by people running a structured fasting protocol or building fasting into an ongoing routine.
Why Use ProLon Products?
- A structured protocol, not loose advice. The kits are portioned and sequenced, so there is no daily decision about what counts as fasting-compatible.
- Plant-based throughout. The range is built on plant sources, with gluten-free, soy-free, vegan and non-GMO products across much of the line.
- Research-linked formulation. The formulations trace back to the longevity research program the brand was founded on, which is the reason people choose it over a generic meal kit.
- Everyday and protocol formats. Alongside the multi-day kits, the range includes bars, spreads and shakes intended for regular use.

Who Uses ProLon?
ProLon is bought by individuals running a fasting protocol on their own, by nutrition and wellness practices that guide clients through structured fasting, and by integrative and functional medicine practices that include fasting protocols in a broader plan. It also sells to people who are not fasting formally but want the bars, spreads and shakes as part of a plant-based routine.
Benefits of Using ProLon for Your Facility
For a practice that recommends structured fasting, a portioned kit removes the largest failure point, which is the client improvising meals partway through. Stocking a single line also means one set of ingredient and allergen information to communicate rather than a different one per client. The subscription formats suit clients who repeat a protocol on a schedule.
Choosing the Right ProLon Product
Start with whether the goal is a defined protocol or everyday use. A structured multi-day or single-day kit is the choice when someone is completing a fast on a set schedule. The bars, spread and shakes fit people who want fasting-compatible food without committing to a full protocol, or who want something to carry through a fasting window. The supplement is a daily product rather than a protocol component. Because these are food products, check the ingredient and allergen information on each product page before ordering, particularly for tree nut content.

Why Buy ProLon at MediDepot?
MediDepot lists the ProLon range with the manufacturer's own ingredient, allergen and nutrition information on the page rather than summarized marketing copy, which matters more for food than for equipment. The line sits alongside the rest of the store's nutrition catalog, so a practice can order fasting products and general oral nutrition in the same place.
Frequently Asked Questions
What is a fasting mimicking diet?
It is an eating protocol designed to provide food while keeping the body in a state similar to fasting. ProLon's products are formulated around this approach, which came out of the longevity research program the brand is built on.
Are ProLon products plant-based?
The range is built on plant sources, and much of it is labeled vegan, gluten-free, soy-free and non-GMO. Check the individual product page, since the certifications differ by product.
Do ProLon products contain allergens?
Some do. The L-Spread, for example, is made largely from almonds, which is a tree nut. Always read the ingredient and allergen statement on the specific product page before ordering.
Can I buy ProLon products on a subscription?
Several products are offered in both one-time and subscription formats, with the subscription priced below the single purchase. The available formats are shown as options on each product page.
Is ProLon a medicine or a medical treatment?
No. ProLon products are food and dietary supplements. They are not medicines, they are not a treatment for any condition, and anyone with a medical condition or on medication should speak to their clinician before starting a fasting protocol.
Which ProLon product should someone new to fasting start with?
A single-day kit is the shortest structured option and requires the least commitment. The bars are the lowest-commitment entry point of all, since they can be used without following a protocol at all.
Final Thoughts
ProLon occupies a narrow space: food built specifically to be eaten while fasting. Whether that is worth it depends on whether a person wants the structure of a portioned protocol or simply fasting-compatible food to keep on hand. Browse the ProLon range at MediDepot and check each product page for the full ingredient and allergen detail.
