How Sea Moss is Harvested & Processed & Why Does it Matter?

Sea moss is a superfood. It's packed with nature's goodness and contains almost every vital ingredient that your body needs to survive, thrive, and shine. It contains calcium, magnesium, phosphorus, iron, zinc, you name it, and it has it! It is your natural multivitamin that gently replenishes your body's essential minerals and vitamins without relying on pharmaceuticals.

That sea moss is healthy and pocket-friendly is a well-known fact, but few people know how it is harvested and processed. It is also important to understand these basics, as both harvesting and processing significantly impact product quality and potency.

How?

Let's find out.

Natural Vs Artificial Growth

Sea moss, as you all know, grows on the sea beds of nutrient-rich water. If you collect sea moss as it is, it's called wildcrafted. Wildcrafted sea moss is the most natural form and the gold standard against which other forms are compared or prepared. 

If you grow sea moss in a man-made pool, it's called pool-grown sea moss. Pool-grown sea moss is a farmed variety with added nutrients. 

• Wildcrafted sea moss is more nutrient-rich than the pool-grown variety. 

• It has more bioactive compounds, has a better authentic and natural texture and aroma. 

• Pool-grown sea moss is relatively cheaper than the wildcrafted variety but has a more uniform appearance.

Cleaning & Drying

Once collected or harvested, raw sea moss goes through cleaning to remove sand and salts. Cleaning is vital to remove the debris from the weed. Once cleaned, it is sun- or solar-dried by spreading over plastic sheets or raw bamboo sticks. The purpose of sun-drying is to reduce the moisture content to 40% or less. 

Over-exposure to the sun or over-drying (with artificial means) can strip the weed of its vital nutrients, particularly phenolic compounds. Gentle drying is key to preserving the bioactive compound for health benefits.

Dosage Form - Gel, Powder, or Capsule

Once dried, sea moss is ground into powder, which is left as such or blended into gel. The nutrient profile remains the same in both cases, but if high temperatures are used for a long time, some important nutrients can be lost. This is why Herbal Vineyards uses natural methods to preserve the minerals and vitamins. 

All three forms, gel, powder or capsules, provide the same health benefits:

• Improve immunity

• Strengthen thyroid function

• Help gut health

Quality Assurance

Another thing to ensure, as you buy the sea moss product, is third-party lab testing, which guarantees that every batch meets the safety standards. 

Every step in sea moss collection, harvesting, and processing matters, so choose the best seller, choose Herbal Vineyards, because we ethically harvest and lab-test our products to ensure 100% goodness and quality.
