Quick Summary

Several Metamucil options, including capsules and unflavored powders, contain no added sweeteners. The brand also offers a Premium Blend sweetened with stevia for a plant-based, sugar-free alternative. Other natural psyllium husk products from different manufacturers provide additional choices for those avoiding aspartame and sugar.

Metamucil Options Without Added Sweeteners

For consumers seeking to avoid both sugar and artificial sweeteners like aspartame, several Metamucil formulations are available. Unlike many flavored sugar-free versions that use aspartame, Metamucil offers products that are unflavored and contain no added sweeteners.

Unflavored Metamucil Powder

One option is the unflavored psyllium husk powder, which is free from aspartame and added sugar. Its minimal ingredient list typically includes psyllium husk, maltodextrin, and citric acid. This makes it suitable for mixing into various liquids without significantly changing the taste.

Metamucil Capsules

Metamucil also provides psyllium husk capsules, offering a convenient, pre-measured dose of fiber without added sweeteners, flavors, or sugar. These are a good choice for those who dislike the taste or texture of powders. Remember to take capsules with a full glass of water.

Metamucil Premium Blend

A third option is the Metamucil Premium Blend, which is sugar-free and uses plant-based stevia as a sweetener instead of aspartame. This provides a flavored, yet artificial sweetener-free, experience.

Natural Psyllium Husk and Generic Alternatives

Besides Metamucil, numerous pure psyllium husk products are available from other brands that contain no sugar, aspartame, or other additives. These can be more cost-effective and offer complete control over ingredients, often sold as bulk psyllium husk.

Advantages of Generic Psyllium Husk

Purity: Many generic options contain only psyllium husk.
Cost-Effective: Generic psyllium is often more affordable.
Versatility: Pure psyllium husk can be added to various foods or mixed with natural sweeteners.
