Best Kelp Powders

As a supporter of healthy living and nutrition, I have tried many different superfoods and supplements over the years. Recently, I discovered kelp powder and have been amazed by its incredible nutritional profile.

Best Kelp Powders

Kelp is a type of seaweed that is rich in vitamins, minerals, antioxidants and other beneficial compounds. After doing extensive research, I decided to start taking kelp powder daily as part of my diet.

I will share my personal experience and advice on the best kelp powder to buy. As someone who has sampled products from several brands, I have insights into the key factors that make up a quality kelp powder.

                    My Advice When Buying Kelp Powder:

                    When searching for the highest quality kelp powder, pay attention to a few key factors:

                    Source of the Kelp

                    Where the kelp comes from significantly impacts its nutrient content. Iceland and Norway have very clean, unpolluted waters ideal for harvesting nutritious kelp. Contaminants are minimal, and their cold waters boast a vibrant ecosystem for kelp to flourish.

                    Certain brands also sustainably wildcraft by hand in pristine waters, maximizing preservation of the environment. These meticulous sourcing practices result in a superior quality product.

                    Processing Methods

                    Look for kelp powder made from raw, freshly harvested seaweed. The harvesting and drying process should avoid high heat, excessive light or oxygen exposure. Too much processing depletes nutritional content.

                    The best powders use gentle roller drying or low temperature air drying techniques. These minimize damage to enzymes, vitamins and antioxidants. Verifying the production process ensures maximal preservation of the kelp’s nutritional richness.

                    Purity & Composition

                    Search for 100% pure kelp powder, without additives or fillers. It should consist of finely ground whole kelp fronds, containing the entire nutrient spectrum of the sea vegetable.

                    I also prefer powders made from Ascophyllum nodosum species of kelp, which offer a diverse array of vitamins, minerals, antioxidants and phytonutrients for optimal nutrition. Really high quality kelp powder is just pure, dried kelp with all its amazing health promoting compounds intact.

                    Taste & Texture

                    The highest grade kelp powder has a mild ocean-like taste and reasonably fine, smooth texture. It should dissolve fairly well in water, juices or smoothies without clumping.

                    I tend to use powders as ingredients blended into other foods and drinks. So texture and solubility does impact my experience. Just something to potentially consider depending on your intended uses for the supplement.

                    Price & Value

                    When purchasing a health supplement, I always evaluate if the quality aligns with the price tag. Inexpensive kelp powder likely cuts corners in their production practices.

                    However premium kelp powders with the highest purity, nutritional content and most meticulous harvesting do warrant a higher price. Evaluating the standards and sourcing really informs if the price matches the overall value.


                    Reputable kelp powder brands have their products tested for heavy metals and contaminants. They also comply with current Good Manufacturing Practices (GMP). Those carrying organic, non-GMO, or B Corporation certifications indicate further commitment to purity and ethics.

                    Reviewing a company’s approach, testing standards and certifications provides helpful insight on their quality control. This legwork on the front end leads to more peace of mind in the supplements you ultimately select.


                    What are the benefits of taking kelp powder?

                    Some of the top benefits reported from taking kelp powder include:

                    • Thyroid support - Rich source of iodine to promote healthy thyroid hormone production
                    • Immune function - Contains antioxidant vitamins C and E to support immune health
                    • Cardiovascular function - Has heart health minerals like magnesium and calcium
                    • Digestion - Aids digestion and gut health with prebiotics and fiber
                    • Anti-inflammatory - Includes bioactive compounds that help reduce inflammation
                    • Detoxification - Supports the body's natural ability to detox heavy metals and toxins

                    How much kelp powder should I take per day?

                    Most kelp powder supplements recommend taking 1-2 grams or 1⁄4 to 1⁄2 teaspoon per day. This provides sufficient iodine, vitamins, minerals and antioxidants without going overboard.

                    Those with thyroid issues already being treated should exercise additional caution and consult their physician before taking new iodine rich supplements.

                    When is the best time to take kelp powder?

                    I prefer taking kelp powder in the morning, at least 20-30 minutes before food or other supplements.

                    However kelp powder is quite flexible. It can be taken anytime that works best, either solo or blended into smoothies, juices, yogurts and more.

                    Experiment to find what timing you prefer for your daily routine. Just be consistent once you decide when it fits in best.

                    What does kelp powder taste like?

                    Kelp powder has a distinct briny, ocean-like flavor. The taste is actually quite pleasant, mild and a refreshing change from typical greens powders.

                    I don’t mind it solo stirred into water. But it also blends very nicely into other foods and drinks without overpowering them. So the taste should not deter you from the immense nutritional benefits kelp powder offers!

                    Can I take kelp if I have thyroid issues?

                    You can take kelp powder if you have low thyroid function since the iodine aids production of thyroid hormones. However those being treated for hyperthyroidism or autoimmune thyroid conditions should first consult their physician before taking kelp powder.

                    For these thyroid issues, the high iodine content could potentially aggravate symptoms. But your doctor knows your condition best and can guide if kelp powder is appropriate.


                    I highly recommend incorporating kelp powder into your regular diet and nutrition regimen. It offers an incredible array of vitamins, minerals, antioxidants and health promoting compounds essential for whole body wellness.

                    Based on my personal experience sampling various brands, I feel Starwest Botanicals Organic Kelp Powder provides exclusive quality and purity. It delivers exceptional nutritional properties. Their production process maximizes preservation of heat-sensitive compounds too.
