D-Aspartic Acid – Pure raw material for your protocols

The D-Aspartic Acid powder from RawSeries is a dietary supplement based on D-aspartic acid.

A raw powder made up exclusively of 100% pure D-Aspartic Acid. It contains no additives, anti-caking agents, sugars, or other ingredients that could interfere with customizing your daily intake. It’s an amino acid in its D- form, known and used in advanced sports nutrition as an ingredient often included in specific protocols, especially in strength training environments and high-level athletes. As a RawSeries product, you’ll find it in the cleanest and most transparent form possible, 100% pure, so you decide how to integrate it into your nutrition plan.

A single-ingredient product, no extras: just pure D-Aspartic Acid powder.

If you’re looking for a pure, clear raw material designed for personalized sports formulas, this D-AA is made for you.

What HSN Raw’s D-AA is like

The philosophy behind our RawSeries line is to offer unique, high-purity ingredients so advanced users have maximum control over their nutrition. In this case, the product contains only D-Aspartic Acid, with no other added components.

The powder has a naturally acidic taste, due to its own nature, and includes no flavors or sweeteners. That’s why many users prefer to mix it with other flavored raw materials or drinks they’re used to, to better fit it into their daily routine.

Who the D-Aspartic Acid powder is for

This product is especially aimed at users with some experience in sports nutrition, who already know about D-Aspartic Acid and want to include it in their plan with specific goals.

It’s great for:

•  Strength athletes and performance-focused training folks working with advanced, periodized protocols.
•  RawSeries users who prefer additive-free, single-ingredient products that are easy to combine with other raw materials.
•  People who want to design their own sports “stacks” by adjusting doses based on their own judgment or advice from coaches or nutritionists.

D-Aspartic Acid in the context of sports nutrition

D-Aspartic Acid has caught the interest of the sports and scientific communities over recent years, and it’s often found in products aimed at strength and gym users.

In practice, many advanced athletes include it as part of specific protocols, adjusting usage periods, especially during volume training phases, combined with other ingredients like tribulus extract, boro, or vitamin D.

How to use D-Aspartic Acid in your daily routine

The powder format makes it super easy to include D-AA in your daily routine, since you can precisely adjust the dose.

General usage recommendation

The usual guideline is to mix 1 scoop of 10 ml (about 3 g) in 200 ml of water, once a day. You can take it whenever fits best with your plan (for example, with a meal or as part of your pre-workout routine) — find a convenient time to keep it consistent.

Practical ideas to integrate it

•  Mix it with cold water or a drink with HSN flavoring for amino acids to soften its slightly acidic taste.
•  Add it to your pre-workout protein shake.
•  Include it at times of day when you already have the habit of taking other powdered products, to improve routine adherence.

How to include it in your sports stack

One of the biggest advantages of D-Aspartic Acid powder is its ability to fit into advanced supplementation schemes. Being a single-ingredient product, it easily combines with other common ingredients.

Example of integration in a strength athlete’s stack

•  Daily base: Use protein powder (could be plant protein or other protein sources) and creatine monohydrate.
•  D-Aspartic Acid: Take 3 g daily, at the time that best fits your schedule (many users take it pre-workout).
•  Other supplements: intra-workout powdered carbs, depending on session volume and intensity.

Example of use during higher load phases

During especially demanding training phases, some athletes keep their usual supplementation scheme (protein, creatine, electrolytes, etc.) and add D-Aspartic Acid as an extra element.

Questions and answers about D-AA

What’s the difference between this D-AA and others on the market?

The main difference is the approach we take in our RAW range: We use 100% D-Aspartic Acid raw material, with no additives of any kind. This lets you include it in personalized protocols without interference from other components.

What does D-Aspartic Acid powder taste like?

It has no added flavorings, so it keeps its naturally acidic taste profile. Many users prefer mixing it with other flavored preparations or drinks they’re familiar with, although its natural taste isn’t strong.

Is it suitable for vegans?

Yes. HSN’s D-Aspartic Acid powder is vegan-friendly and contains no animal-derived ingredients.

D-AA base vs 'D-AA Ca'

Some commercial versions of D-Aspartic Acid use “calcium” forms or salts derived from the amino acid, meaning part of the final product isn’t pure D-AA but a combination with calcium. This lowers the actual percentage of D-Aspartic Acid available per gram.

In contrast, our product contains 100% base D-Aspartic Acid, with no added salts or intermediate compounds. This means the amount shown on the label fully corresponds to the compound itself, allowing total dose control and more precise integration into personalized protocols.

For those seeking the purest form, the base option is the best choice.
