Indigold and algal DHA explained
Indigold is one of the ingredients named in Vplus Formula. It contains algae extracts and Crypthecodinium cohnii, a microalga used as a source of DHA. Understanding that source is useful, but it does not tell you the DHA amount in a finished serving.

What is in the Indigold blend?
The Vplus ingredient list names Chlorella sorokiniana, spirulina and the Indigold blend. Indigold includes Chlorella sorokiniana extract, spirulina extract and Crypthecodinium cohnii. An extract is a preparation taken from a source ingredient; its composition depends on how the producer makes it.
Read the current product information for the full formula and serving directions. The amount of a blend is not the same as the amount of each component within it.
What is Crypthecodinium cohnii?
Crypthecodinium cohnii is a marine microorganism that can produce DHA. Researchers cultivate it using a carbon source, such as glucose, in fermentation systems. This is an established way to obtain DHA without extracting oil from fish.
Research on a species or a purified oil does not give the DHA concentration of Indigold or Vplus. For a milligram comparison with an omega-3 supplement, use a DHA amount declared for the finished product.

How do algal DHA and fish oil compare?
Algal oils and fish oils can both contain DHA. The source matters for dietary preferences; the amount per serving matters when comparing the products. Fish-oil products often list EPA, and some algal oils do too.
Check the complete ingredient list, including any capsule shell, and any certification you need. If a doctor or pharmacist has set you a particular omega-3 amount, show them the label rather than substituting a different product by ingredient name alone.
